3. OPERATION 3.1 INTRODUCTION The Scanner has two different modes of operation, ‘RUN’ mode and ‘PROG’ / MENU CONFIGURATION mode. The first - RUN mode is the normal operating mode of the scanner in this mode the scanner scans the input channels, displays the process values and channel information, and monitors the alarm limits. The other mode ‘PROG’ or Menu configuration mode is used to navigate through the menu options and configure the scanner as per user requirement.

For your instrument to operate properly the user must first program or configure the

system through the configuration menu. 3.2 RUN MODE 3.2.1

On power on a self test is done and all LEDs and displays light up for a few seconds, the scanner then displays the hardware configuration setup sequentially for a few seconds. The ‘Fn’ display shows ‘Su’ (setup). The value window displays the following information: -

1. v xx = Version Number 2. Ch xx = Number of channels 3. rL xx = Number of relays provided. 4. Input type available (First type) 5. Input type available (Last type)

If only one input type is available item 4 and 5 will be the same. If more than one type

is available item 4 will display the first input from the input list and 5 will display the last item from the list , all inputs in between will be available. After the setup display the system is ready and the display indicates: MCS rdy The scanner enters RUN mode and normal scanning operation is performed. If any channel has exceeded its Alarm set points the corresponding channel alarm LED starts flashing and if any relay is assigned to the alarm the corresponding relay is also energized. Alarms can be programmed to be latching ‘TRIP’ or non-latching ‘ALARM only’ types. Refer to section 3.2.3 ALARM OPTIONS for details.



3.2.2 AUTO / MANUAL SCAN MODE Two display scanning options are provided namely AUTO and MANUAL. In Auto display scanning mode the channel display scanning of the system is automatic and the display shows the channel number and its corresponding values sequentially as per selected rate. Pressing the [HOLD/SCAN] key in auto mode would hold the particular channel value and HOLD LED would keep flashing. Pressing the [HOLD/SCAN] key again would revert to auto sequential display scanning. In Manual display scanning mode HOLD LED is steady on. The system operates in manual mode indicating the current channel number and its value continuously on the display. The channel number could be increased / decreased by using [UP] or [DOWN] keys.

3.2.3 ALARM OPTIONS

Alarms are arranged in two groups A1 and A2, each channel has one alarm from A1 group and one alarm from A2 group. Each groups alarm mode can be configured for non-latching (ALARM only) or latching (TRIP) Mode operation. The sensor break or error condition output for each group can also be set separately. 3.2.3.1 ALARM MODES

ALARM only – Non latching (auto reset) mode, in this mode once a channel crosses its alarm set point the corresponding alarm LED starts flashing and the associated relay if any is energized. If [ENTER / ACK] key is pressed the LED becomes steady and the alarm relay is de-energized. When channel value returns to normal the alarm LED is OFF, if the alarm was not acknowledged earlier both the LED and relay are automatically reset.

TRIP – Latching mode, in this mode once a channel crosses its alarm set point the corresponding alarm LED starts flashing and the associated relay if any is energized. If [ENTER / ACK] key is pressed the LED becomes steady and the alarm relay continues to be ON. When channel value returns to normal if alarm was acknowledged the alarm LED and relay is reset.

In all cases the internal channel scanning and alarm monitoring is always maintained irrespective of the display mode.

In ALARM only mode, alarm relay is automatically reset as soon as channel value return to normal or fault is acknowledged. This mode is normally used where an audio alarm / electronic hooter is connected to the relay output and needs to be disabled as soon as the operator acknowledges the alarm. Or an external alarm annunciator unit is used.

In TRIP mode the alarm is required to be acknowledged by pressing the [ENTER / ACK] key so that the alarm LED and relay is reset when process value returns to normal.



3.2.3.2 ALARM OUTPUT IN SENSOR BREAK / ERROR CONDITION The alarm output status for each group on sensor break or error condition can be separately set to either enable alarm or disable alarm under such conditions. 3.2.3.3 ALARM TYPE The type of alarm ‘High alarm’ or ‘Low alarm’ or ‘Alarm off’ can be separately programmed for each channel. Four combinations are available for each channel:

TYPE A1 A2 REMARKS

OFF ALARM OFF ALARM OFF -

H-L HIGH ALARM LOW ALARM -

H-VH HIGH ALARM VERY HIGH ALARM Set A2 > A1

L-VL LOW ALARM VERY LOW ALARM Set A1 > A2

3.2.3.4 A1 & A2-ALARM SET POINTS The A1 and A2 alarm set points for each channel can be set independently for all channels.

3.3 PROG MODE / MENU CONFIGURATION MODE This mode is used for programming or configuring the scanner as per user requirement. This mode is protected by two level security code, the first level is the USER LEVEL where access is available to the normal configuration parameters required by the user. The second level is the FULL ACCESS LEVEL, which is normally required only during initial setup of the scanner.

To ensure that the scanner is not left in PROG mode, the scanner automatically returns to RUN mode if no keyboard activity is detected within 30 seconds. 3.3.1 ENTERING PROG MODE

To enter into PROG. mode , keep [PROG/RUN] key pressed at the time of power on. (If scanner is running press [PROG/RUN] key and [PRN/NEXT] keys simultaneously)

To configure alarms as High - Very high or Low - Very Low for each channel appropriate set points A1 and A2 are to be configured as functionally both A1 & A2 are identical.

In PROG mode system does not monitor the inputs and the relays remain in the previous state.

4. INSTALLATION

Before proceeding with the installation please check the label to verify the rating.

4.1 Install the scanner in the panel cutout and tighten the fixing clamp carefully.

4.2 POWER CONNECTION

Connect the 90VAC - 260VAC, 50/60Hz power supply to the terminals marked ‘L’ Live, ‘N’ Neutral

& ‘E’ Earth. Refer TABLE-3.

Be sure to connect L, N and E as indicated. Failure to wire the power as indicated could result in damage to the scanner.

Do not connect power to your device until you have completed all input and output connections. Failure to do so may result in injury!

Do not enter Calibration Mode unless system is out of calibration and you have fully understood the Calibration Procedure.

Calibration details are given in separate calibration manual



Also refer to Safety Considerations in section 1.2 4.3 SENSOR CONNECTION

Connect the sensor / inputs to the appropriate terminals - refer TABLE-1. Care should be taken during installation to check polarity of the wires.

4.3.1 THERMOCOUPLE INPUT (Type – J, K, T, E, B, R, S, N)

• This input must be wired by using proper thermocouple compensating or extension cable of the type of input selected.

• Normally un-grounded thermocouples (TC) should be used. If grounded type TC is used then other inputs should be isolated since they will also get grounded.

• Polarity of cables must be maintained.

4.3.2 RTD INPUT (Type – PT 100, Ni 100, Cu 50, Cu 53)

• PT 100 RTD are as per 385 curve (0.385 ohms/deg.C - DIN 43760)

• For two-wire RTD short ‘-‘ & ‘R’ and connect RTD between ‘+’ & ‘-‘ • The two-wire connection is simplest method, but does not provide wire resistance

compensation that may lead to reading error due to connecting cable resistance.

• The three-wire connection provides wire resistance compensation and produces excellent lead-resistance cancellation for balanced measurements. So three-wire connection is recommended.

To prevent shock ensure that the instrument is properly earthed.

Thermocouple Wire Colors are different as per different Standards. Please check your manufacturers specification for the polarity indication.

Signal cables should be routed away from all power cables and cables connected to relay contacts.

Use shielded cable for signal wiring.

Tighten all RTD cable terminals properly, loose junction box terminals or connectors will lead to erratic readings.



4.3.3 Process / Linear Input – VOLTAGE (0 to 5V or 1 to 5V)

4.3.4 Process / Linear Input – CURRENT (0 to 20mA or 4 to 20mA)

• Connect 150Ω conditioning resistance across ‘+’ & ‘-‘ terminals for current input. • Current loops connected to the system should be isolated or share a common return path

to the negative terminal due to common negative terminal. 4.4 RELAY CONNECTION

Connect the potential free contacts from the ALARM relays as required. Terminal numbers for

relay contacts are given TABLE-2.

• Voltages greater than 5.6 Volts should not be applied; this may affect accuracy of other channels or damage the input.

• If voltage inputs are left open you may get floating values, so the inputs must be either shorted or switched off and not be kept floating.

Relays provided are for alarm annunciation. Switching heavy loads is not recommended. In case of inductive loads use suitable RC snubber network. Recommended values for R & C are R = 470 ohm and C = 0.1 uF/250V, RC value will depend on connected inductive load.

10. CALIBRATION

The Scanner is factory calibrated for the three basic types RTD, Thermocouples and Volts. The calibration is not required to be changed if the input type is changed. However if the scanner is required to be recalibrated in case of error over time, or any component has been changed, the calibration procedure is as follows. The Scanner has auto calibration feature. It gets calibrated automatically when the required input in the acceptable range is given. If its not in acceptable range it is rejected and there is calibration failure.



EQUIPMENT REQUIRED:

INPUT TYPE EQUIPMENT REQUIRED

RTD –PT100 Decade resistance box 0 to 400.0 Ohms accuracy 0.05% or better.

Thermocouple 1. 0 to 75.00 mV calibrator, accuracy 0.05% or better. 2. Thermometer 0 to 60 Deg C, 0.1 Deg C resolution, accuracy

0.1 Deg C or better.

VOLTS 0 to 5.000 V DC Precision voltage source, accuracy 0.05% or better

Connect the following inputs to the following channel:

CHANNEL INPUT TYPE VALUE

Channel - 1 RTD input 400.0 Ohms

Channel - 2 Thermocouple input 75.00 mV

Channel - 3 Voltage input 5.000 V

(Refer Table – 1 of USER MANUAL for the connections).

CALIBRATION PROCEDURE:

The scanner need not be opened for recalibration and the calibration can be done from the front panel keyboard. There are no internal potentiometers and the entire calibration is done digitally via software.

Before proceeding with calibration ensure that the required equipment is available, and the calibration procedure is fully understood, improper calibration will change the factory calibration and make the scanner unusable or display incorrect reading.

ENTERING CALIBRATION MODE:

Enter the PROG mode and enter password 135, to access the full menu. Press NEXT key till display shows:

Before calibration ensure that the scanner is at room temperature and provide a

warmup period of 15 minutes.

The above-mentioned inputs should not be changed as this will lead to calibration failure.

Before entering calibration mode connect the three calibration inputs to channel 1, 2 and 3.



Set Cal If you want to continue calibration press the ENTER key else to exit press the [>] NEXT key. On pressing ENTER display shows:

CPS 000 Use the UP key to change 000 to 015 and press ENTER. This will access the calibration menu. The display indicates the following sequentially as follows:

C1 rtd 400.0 C2 tC 75mV C3 Lin 5.00 CJC 00XX Where ‘00XX’ is the previous set ambient temperature (eg 30.0 Deg C). Measure the ambient temperature (back terminal temperature) and set this value using the UP or DOWN key. Press ENTER and display changes to:

CAL busy The Scanner now starts auto calibration based on the input values at terminal 1,2 and 3. This process should take 2 to 3 minutes.

Display then indicates the following one after the other:

rtd Pass tC Pass



CJC Pass Lin Pass

And then display returns to:

Set CAL The calibration is now complete.

If any of the inputs at channel 1, 2 or 3 are incorrect or Scanner has hardware failure then display would indicate ‘FAIL !!’ instead of ‘PASS !!’.

Press the PROG/RUN key to quit PROG mode or press the NEXT key to return to first item of the Prog menu.
