Modules

The modules comprising the 505ITM include:

RTD Input Module

CT Input Module

AC Voltage Input Module

Potentiometer Input Module

DC Voltage Input Module

Current Input Module

Dry Contact Closure Module

Powered Contact Closure Module

RTD Input Module

RTD Input Modules are used for monitoring liquid, ambient, or if used in a heated well,

winding temperatures. The input to the module is either a 100 ohm platinum RTD or 10 ohmcopper RTD.

For measuring liquid or ambient temperatures, the module is scaled over the range of -40 -120 C. If it is used in a heated well, the scale is -40 - 200 C. When ordering the 505ITMfrom the factory, the temperature requirements need to be specified.

CT Input Module

The CT Input Module is used to monitor winding temperatures, winding currents, motorcurrents of LTCs, or fan currents. The input to the module is a clamp on the CT, provided byQualitrol, which has an input range of 0 - 5 A, 0 - 10 A, or 0 - 20 A, other ranges areavailable, and an output of 0 - 0.333 VAC, can be used as the input to the CT Input Module.

If this module is used for winding temperatures, the scaling is in the range of -40 - 200 C;for anything other than temperature, the range is scalable to a maximum of 99999.9 C.


The AC Voltage Input Module is used to monitor any AC voltages under 320 VAC. The inputmodule works in conjunction with the Qualitrol Voltage Sensor, TRA-600-1, and measuresranges of either 0 - 140 VAC or 0 - 320 VAC.

The range is scalable to a maximum of 99999.9 VAC.


The Potentiometer Input Module is used for monitoring liquid level, flow gauges, or gasaccumulation. The input to the module is a potentiometer that is typically supplied byQualitrol. The range of the potentiometer input is up to 15,000 ohm. Typically, the 25 markon a liquid level dial is set to the center of the potentiometer range, and the high and lowreadings are simply ratios of the angular deflections from the normal setting. Qualitrolgauges use a 340 angular degree potentiometer on a 2:1 gear ratio from the dial travel tothe potentiometer travel. The Potentiometer Input Module must be calibrated on site. For


11/113



more information, see the Using the Factory Calibrator Tool (Advanced users, only)sectionin the SoftwareInstructions.

The scaling of the 505ITM for this module is 0 - 100%.


The DC Voltage Input Module is used for monitoring transducer outputs with an outputsignal in either the 0 - 100 mVDC or 0 - 10 VDC range.

The range for this module is scalable to a maximum of 99999.9 VDC.


The Current Input Module is used for monitoring transducer output with an output signal ineither the 0 - 1 mA DC or 4 - 20 mA DC range. These can be devices such as pressuretransducers for measuring main tank pressure, bushing pressure, or dissolved gas in oiltransducers.

The input module can be configured to operate with either two-wire loop transducers, which

are powered by the module, or three-wire transducers that are powered by the module orfrom the transducer.

The range for this module is scalable to a maximum of 9999.99 mA DC.

Dry Contact Closure Module

The Dry Contact Closure Module is used for monitoring a contact and indicating on a displayif it is open or closed. An open contact means there is no connection between the contacts;a closed contact signifies a shorted connection across the contacts. This can be used, forexample, to monitor pumps or fans. The system internally treats closed and opened contactsas either a 0 or 100 numeric value. Therefore, if the module is used to control a relay, therelay set point should be set at midrange, e.g., 50.

This module can monitor a non-powered, dry contact.

Powered Contact Closure Module

The Powered Contact Closure Module is used to monitor a powered contact, and it indicateson the display whether it is opened or closed. An open means there is no connectionbetween the contacts, and closed indicates a shorted connection across the contacts. Thiscan be used to monitor alarms or active fans, for example. The system internally treatsclosed and open contacts as either a 0 or 100 numeric value. Therefore, if the module isused to control a relay, the relay set point should be set at midrange, e.g., 50.

This module can monitor a powered contact of >80 VAC/DC or >130 VAC/DC jumperselectable.

Heater Option

If the Enclosure or Panel Mount monitor is supplied with the Heater Option, the supplypower, 120 or 240 VAC, as specified when ordering, is applied to Terminal Block TB1terminals 1 and 17, as shown in the Heater Option Connection figure.

Heater Option Connection

Qualitrol recommends that the heater circuit be installed with a fuse for safety and protectionpurposes. The fuse is the responsibility of the installer. The rating of the heater is 75 watts at120 VAC. A 240 VAC heater uses two of these heaters in a series, for a total of 150 watts.Qualitrol recommends installing a slow-blow fuse rated at 1.00 A, at 600 V.

RTD Input ModulesFor each RTD Input Module, one standard 100 ohm RTD (or 10 ohm RTD), with a three-conductor, shielded cable is required to measure liquid and ambient temperature, or if in aheated well, winding temperature. The three conductors and the shield drain lead areconnected to the monitor, as shown in the RTD Input Wiring Connections figure.

CAUTION: RTD wiring should be continuous, and the shield drain lead must begrounded only at the instrument.

The monitor uses a compensation scheme for the RTD cable connection. The three-wireconnection compensates for the resistance of the connecting wires.

RTD Input Wiring Connections

If you are upgrading an existing Qualitrol device, or if the RTD you have installed is a four-wire RTD, DO NOT connect the fourth wire in parallel with the third wire, this will adverselyaffect the compensation scheme.

If you have a fourth wire on the RTD connection, cut the fourth wire flush with the jacket.Qualitrol recommends a maximum length of 75 feet for RTD cabling.


17/113



Note: Due to dimensional and mounting variations, the RTD, well, and connector must beordered separately and are available from Qualitrol.

CT Input Module

For each CT Input Module, one standard clamp on the CT, TRA-017-X, is required to

calculate winding temperature or currents. Input the current range as specified.

Pull the supplied Qualitrol clamp on CT Sensor apart and place the wire which carries thecurrent to be sensed, into the CT opening. Push the CT sensor back together and check thatit is fully engaged. As shown in the CT Input Connections figure, connect the output wires ofthe clamp on CT to the terminal board.

CT Input Connections

The Qualitrol clamp-on CT sensor comes with 20 feet of cable. While it is not recommendedto run the wire longer than 20 feet, if the application requires a longer distance, splice thelonger cable as close to the clamp on sensor as possible. This replacement cabling shouldconsist of shielded twisted pair wire.

Note: Because the CT sensor is isolated from the transformer, the burden is so small it canonly be measured in a laboratory. For all practical purposes, the burden sensed bythe transformer is zero.

Caution: The 505ITM measures current using the clamp on CT sensors. Wiringcurrent directly to the 505ITM will damage the unit.


18/113




For each AC Voltage Input Module, one AC Voltage Sensor, TRA-600-1, is required tomeasure the AC voltage. The module can measure either 0 - 140 VAC or 0 - 320 VAC,50/60 Hz, as specified at the factory. Connect the voltage to be measured to the sensorinput Terminal Block TB1 of the voltage sensor (TRA-600-1). Then connect the sensor

output to the terminal block of the AC Voltage Input Module, as shown in the AC VoltageInput Connections figure.

AC Vol tage Input Connections

Caution: The 505ITM measures voltage using the Voltage sensor. Wiring direct ly tothe Voltage Input Module wi ll damage the unit.


For each Potentiometer Input Module, one standard potentiometer in the range of 1500 -15000 ohm, as supplied by various Qualitrol case assemblies, is required to measure liquidlevel, flow, or gas accumulation. The module must be calibrated on site. See the Using theFactory Calibrator Tool (Advanced users, only)section in the Software Instructions.

The three conductors and the shield drain lead are connected to the monitor, as shown inthe Potentiometer Input Connections figure.

CAUTION: Wiring should be continuous, and the shield drain lead must begrounded only at the instrument.

Potentiometer Input Connections


19/113




For each Voltage Input Module, one voltage transducer, 0 - 100 mVDC or 0 - 10 VDC, asspecified, is required.

Connect the output wires of the transducer to the terminal block as shown in the DC VoltageInput Wiring figure.

DC Voltage Input Wiring


The Current Input Module is configurable to accept either a 0 - 1 mA DC or a 4 - 20 mA DC(SCADA type) signal. Either of these options can be a transducer that is:

2-wire, self-powered from the transducer

2-wire, powered from the input module

3-wire, powered from the input module

For each Current Input Module, one current transducer (0 - 1 mA DC or

4 - 20 mA DC) is required.

Connect the output wires of the transducer to the terminal block as shown in the CurrentInput Wiring figure.

Current Input Wiring


21/113



Dry Contact Closure Input Module

The Dry Contact (Switch) Closure Input Module is designed to detect the actuation or de-actuation of one dry, non-powered switch contact. The system internally treats closed andopen contacts as either a 0 or 100 numeric value. Therefore, if the module is used to controla relay, the relay set point should be set at midrange, e.g., 50.

See the Contact Closure Wiring figure for the correct circuit wiring.

Contact Closure Wiring

Powered Contact Closure Input Module

The Powered Contact (Switch) Closure Input Module is designed to detect the actuation orde-actuation of a powered switch contact. This is accomplished by measuring a potentialacross the switch contact of 0 volts when closed and a potential greater than 80 volts AC/DCcontact is open. For applications where a higher potential is being measured, e.g., 240 V

AC, 250 V DC) there is a jumper on the board that can be moved that will raise the sensevoltage to 130 V, if required. The system internally treats closed and open contacts as eithera 0 or 100 numeric value. Therefore, if the module is used to control a relay the relay setpoint should be set at midrange, e.g., 50.

See the Powered Contact Wiring figure for correct circuit wiring.

Powered Contact Wiring


22/113



Output Contacts

Five isolated sets of normally open/normally closed output contacts, for Output Relays 1 - 4and the System State Output Relay, are provided for controlling cooling equipment,sounding an alarm, or operating remote breaker coils.

35/113



Setup alarms, communications, and other features.

Factory Setup Allows the factory to configure the 505ITM. This tool is not accessible tothe user.

Password Each tool requires a password. Passwords are set at the factory, butyou can change them when you are in the tool. The factory setpasswords are:

Monitor 111111

Simulator 111111

Calibrator If required, call Qualitrol ApplicationEngineering at 585-586-1515 x 410.

Customer Setup 111111

The Factory Setup tool can only be entered by Qualitrol factory

personnel. This section is reserved for the factory except in the Demomode(offline).

Remember MeCheck Box

By checking in this check box, the password is stored in thecommunications file so that you do not have to re-enter it every timeyou start the tool.

Important: Enabling this feature will disable security protection andallow anyone using this computer to gain access to thesoftware.

Start Button Activates the selected tool.


36/113



Opening a ToolTo open any of the 505ITM software tools, do the following:

1. Establish communications with the 505ITM.

2. From the Desktop Menuwindow, enter the correct password for the tool you wish tostart.

Note: If the Remember Mefeature is enabled, you do not have to enter a password.

3. Click [Start].

Using the Monitor ToolThe Monitor tool provides remote monitoring and control of the 505ITM by simulating thecontents on the 505ITM LCD, and relay LEDs appear on your PC screen. The monitorrequests an update from the 505ITM three times every second.


37/113



There are eight control buttons on your PC screen: Test, Reset, Menu, Enter, Up, Down,Left, and Right. These buttons are activated by clicking on them with the left mouse button.

Activating a button in this way has the same effect as pressing the same button on the505ITM monitor itself. See the Operationsection of the Hardware Instructionsfor specificinformation on the control and operation of the 505ITM.

Click [Close] to exit the tool.

Note: The actual 505ITM continues to operate when the Monitor tool is closed.


38/113



Using the Simulator ToolThe Simulator tool allows you to simulate values regardless of the actual inputs that thesensors register. The 505ITM responds to the input signal changes from the Simulatorwindow as if the signals originated in the field. This mode is useful for testing items such asrelay connections and wiring.

When you click [Start Simulation]:

The field inputs disconnect from the actual field signals and connect to the signals from theSimulator tool. You can now change the simulated signals remotely as you desire. The

505ITM responds to the simulated signals as if they were the actual field signals.

With the exception of the CT, Temperature signals, the transfer from the field to thesimulation is almost undetectable because the initial simulation value is set to the last valueof the actual field signal. The winding temperature (CT, Temperature) is a calculated valueusing load currents, oil temperatures, and time constants. All of these are bypassed in thesimulation mode where the calculated values are replaced with the simulated values.

Important: While the simulation is active, the actual field signals are not being monitored.If you have Trip functions connected to the 505ITM, you can activate them insimulation mode.

When you click [End Simulation]:

The field signals reconnect to the input of the 505ITM. The 505ITM responds immediately tothe actual field signals.

Note: If you make no changes to any of the input signals for more than 3 minutes, thesimulation ends automatically. Whenever any button is pressed, the 3-minute timerresets.


39/113



Using the Factory Calibrator Tool (Advanced users only)The Factory Calibrator tool allows you to calibrate most inputs. When you f irst enter theCalibrator - Signal Selectionwindow, the Input 1channel is selected by default.

Important: All channels, except for the Potentiometer Input module, are calibrated at the

factory. Under normal operation, they will not need to be calibrated again. Youmust have a separate password for this application for the ITM manager toallow you to use this tool.


40/113



Calibrating the Input Channels

1. Open the Factory Calibrator tool.

2. Select the input channel to calibrate.

3. Click [Calibrate]. The Input Channel Calibrationwindow displays.

4. In the terminal block that corresponds to the input module being calibrated, enter thesignal value displayed in the Set input signal tofield.

Important: The Set input signal tofield displays the value of the external signal thatmust be applied to the module terminals. For the RTD Input Modules, theinput signal is expressed in terms of degrees C. If you continue the calibrationprocedure without inputting the correct excitation (stimulus) signal, you willoverwrite the calibration with invalid data. This will cause the monitor tomalfunction.

5. After you have entered the input signal on the terminal block and it is stabilized, click[Next] to accept the value in the Set input signal tofield.

Note: All channels require at least a two-step calibration procedure. The [Next] buttonchanges to [Finish] for the second step in the procedure. If you want to return to theprevious step, click [Back].

6. Enter the value for the second input and click [Finish]. The calibration of this channel iscomplete.


41/113



Calibrating the Output Channels

The analog outputs can be adjusted in a four-point calibration; see the Output Calibrationsection of the manual for more details. However, this calibration should not be necessarybecause it is done at the factory.

Saving Calibration s in FilesYou can save calibration values in files using the Filepull-down menu. These files have thedefault file extension .qca3.

Import Allows you to import a valid calibration file stored in the PC.

Export Allows you to save the current calibration to a previously specified filefor future use.

Export As... Allows you to save the current calibration in a newly specified file forfuture use.


42/113



Using the Setup ToolsThe User Setup tool allows you to set all the adjustable parameters of the 505ITM. TheFactory Setup tool is used to set the hardware configurations of the monitor. The CustomerSetup limits access to some of the 505ITM parameters, such as serial number,

manufacturing date, and configuration date.

Note: You can save configurations as f iles, which you can use to restore settings or to pre-configure before connecting to the 505ITM. See Importing and ExportingConfiguration Files.

When you open the Customer Setup tool, the Customer - Setupwindow displays. When youopen the Factory Setup tool, the Factory - Setupwindow appears. The windows for bothtools are the same and allow for a specific subsystem to be configured.


43/113



The Setup windows have three main sections:

Password Setup

This section of the System Settingswindowallows you to configure the passwords thatprovide access for the different software tools. The passwords are stored in the 505ITM andhave the following characteristics and requirements:

Passwords consist of one to six alphanumeric characters, and they are case-sensitive.

The password for the User Setup tool is also the password used to enter themodification section of the MENU Mode from the front panel of the 505ITM.

The password for the Calibrator tool must be different from the other tool passwords.This is a precaution to prevent users from accidentally entering the calibration sectionof the monitor.

There is a hierarchy to the password system. The password for the Customer Setuptool will also work in the Monitor and Simulatortools, even if they have differentpasswords. This is because all of the passwords can be changed in the CustomerSetup tool, so it is treated as the master password.

When passwords are changed in the Password Setup tool, the user must enter thenew password values the next time the tools are opened.

There are five Passwordfields and five corresponding Verifyfields. The Passwordfieldsaccept the password values for the associated tools. The Verifyfields are used to check thecorresponding password.

Note: The Factory Setup password is not available to the customer.

To enter a new password:

1. Type the new password value into the Passwordfield. Use one to six alphanumericcharacters.

2. Type the same password value into the Verifyfield. Use the same alphanumericcharacters and the same case as you did in the Passwordfield.

3. Click [Load].

The software compares the values in the Passwordand Verifyfields when they areloaded into the 505ITM. If the values do not match, an error message displays.

Module

This section of the Input Module Setupwindowincludes the fields described below.

Input ModuleNumber

Indicates the input module number that is being configured. This field isfor informational purposes only.

Input ModuleType

Indicates what module type was installed in this corresponding site of the505ITM. This is designated at the factory according to the input modulethat was ordered and installed. If the module type indicates "undefined,"there is no physical module installed in that location.

Input ModuleFunction

Enables and disables the module function. If the input module isdisabled:

It cannot be viewed on the LCD display located on the front panel.

It cannot control any relays.

Input SignalName

Identifies the input module name. The name can be changed and canconsist of up to seven alphanumeric characters. This name will alsoappear on the 505ITM LCD display, along with its input signal value.

Custom Scaling

The configuration parameters in this section of the Input Module Setupwindowallow you tochange the scaling of the process input signal. Custom Scaling is not available if the InputModule Typefieldis set to a "Logic Switch", "AC/DC Input" or Temperature input module,for example, RTDs, Ambient, and CT, Temperature. The fields in this section aredescribed below.

Use CustomScaling

Indicates that custom scaling is defined for the input signal. If the checkbox is checked, you must specify three additional parameters for theinput:

Custom Units Labelfield allows the user up to three characters for aunit of measure, for example, ppm, RH, %.

Low-End Valuefield is the scaled minimum value for thecorresponding minimum input value.

High-End Valuefield is the scaled maximum value for thecorresponding maximum input value.

Custom UnitsLabel

If the Use Custom Scalingfield is checked, the 505ITM uses this labelinstead of the default label defined by theInput Module Typefield. Thislabel can consist of up to three alphanumeric characters.

Low-End andHigh-EndScalingValues

Provide the custom values corresponding to the indicated low-end andhigh-end values for the selected module type. The 505ITM translates theinput signal into the alternate monitors using the low- and high-endvalues provided.

Example:You have a Dissolved Gas Monitor with 0 - 1 mA representinga 0 - 2000 PPM scale. Using a 0 - 1 mA input module, set:

Low-End Scaling Valuefield to 0 mA = 0

High-End Scaling Valuefield to 1 ma = 2000

Custom Units Labelfield to PPM

An input of 0.4 mA would appear as 800 PPM on the display.

CT Current Parameters

If the Input Module Typefieldis set to "CT, Current" or CT, Temperature, this section ofthe Input Module Setupwindowprovides linear scaling between the 505ITM output and theactual current sensed by the Power Transformer CT. The fields in this section are describedbelow.

CT clamp-onsensor Rating

Indicates the maximum rating of the CT clamp-on sensor used with thismodule, for example, 10 Amp, 30 Amp). You can read this rating from theclamp-on sensor. When selecting the sensor value, make sure that:

the maximum rating of the sensor value is greater than the current it

will be sensing. This will prevent saturation. the sensor value is as close to the maximum current reading as

possible. This will optimize the resolution.

CT ratio(2 fields)

Provides the parameters needed for CT Current Scaling. The left fieldidentifies the true current, such as winding or bushing, being sensed bythe instrumentation or metering CT. The right field identifies thesecondary or output of the instrumentation or metering CT that will beused with the 505ITM Clamp-On CT Sensor.

Example:If the Instrument CT on the transformer has a ratio of 1200 : 5Amps, the two CR ratiofields are set to CT Ratio = 1200 : 5. The clamp-on sensor is on the 5 Amp circuit and now acknowledges that the 5 Amp

are passing through the CT to scale the current to the 1200 Amp range.

Winding TimeConstant

Allows you to set the time constant for the temperature rise of thiswinding. The time constant is defined as the time it takes the windingtemperature to reach 63.2% of its final value for a given current input.

Note: It takes approximately five time constants to elapse for thetemperature to reach full value for a given load. If the time

constant is unknown, the IEEE Std C57.91-1995 Annex Grecommends a value between 3 and 7 minutes. Qualitrol uses adefault value of 6 minutes.

Oil Rise Parameters

This section of the Simple CT Temperature Scaling Setupwindowincludes the parametersthat are required if you want to use the Critical Forecast feature of the TransLifeTMSetup. Ifyou are not using the Critical Forecast feature, leave these parameters at the default values.

The fields in this section are described below.

Oil risetemperature

Allows you to set the temperature rise value of the transformer oil atnominal load. This is derived from the Transformer Heat Run Report bytaking the value of the Oil Rise Temperaturefield over ambient atnominal load, and subtracting the ambient test temperature.

Oil Rise Temp = (Oil Rise Temp over Ambient - Ambient Temp)

Oil time

constant

Allows you to set the time constant for the temperature rise of this

winding. The time constant is defined as the time it takes the windingtemperature to reach 63.2% of its final value for a given current input.
