3.1 General Information

This section of the instruction book explains the operation of the control-ler. Read the entire Operation section before operating the unit.

The SCU provides proportional output for a 4-20 mA input, typically aflow signal. The output may control a motor-operated actuator or a pulsedoutput may be selected. A 4-20 mA Output is available, which may be setto represent the output or the 4-20 mA input.

The output can be scaled by the Dosage Factor (DF). This allows the userto change the gain of the controller from 10% to 400%. DF affects actuatorposition, pulsed output, and 4-20 mA output when set to “Out”.

The input signal may also be scaled by the Flow Factor (FF). A typical useof this function is to allow the user to oversize a flow meter for futureincreased demand, while displaying an operating range defined by the user.The 4-20 mA may be scaled from 10% to 400%. The 4-20 mA Output isalso scaled by FF when it is set to “FLOW/IN”.

Control output is determined as follows:

Control Output = (input signal) X (Dos Factor) X (Flow Factor)

Motor-operated actuators are set equal to the Control Output by energiz-ing the motor in the increase or decrease direction through two relays onthe SCU circuit board. When used with a V-notch valve, “increase” opensthe valve. When used with a stroke-controlled pump, “increase” increasesthe stroke length. If the input signal drops below 3 mA, the SCU respondswith a NO FLOW/NO INPUT error message, and drives the actuator tozero (automatic mode only). Some USF/W&T actuators are equippedwith contacts that indicate when the actuator is at the lower stop. This canbe used as a no flow alarm condition.

When a pulsed output is selected, a relay on the circuit board pulses linevoltage at pin 14, at up to 200 pulses per minute.

The SCU utilizes a menu structure to organize user operation and setupfunctions. A flow diagram of basic operation is shown in Dwg.40.100.180.010.

IM 40.100CB UA (A/1-01)


23

3.2 Keypad Function (See Dwg. 40.100.170.010)

Movement through the menus and selections are made using six keyslocated on the front panel. If no keys are pressed for five minutes, the SCUreturns to the first menu.

The keys have the following functions:

• UP/DOWN arrows (3): Used to move up and down a menu; to scrollthrough lists of options; to scroll through numbers.

• “F” (1): Used to move to the next menu, only when at the top of amenu. In calibration, it is used to skip to the next calibration point.

• “E” (2): Used to enter a selection or go to the submenu.

• “*” (5): Used to acknowledge an error message. See Section 4 for adescription of the applicable error messages.

• DOT key (4): Moves back one level; escapes current function with-out making a selection.

All setup selections and calibration points entered are stored in non-vola-tile memory. If power is lost, the settings will remain.

3.3 Main Menus

There are five main menus used to operate the unit: Basic Operation,Setup, Input/Output Setup, Calibration, and Diagnostics.

The following is a summary of operation in each of the five main menus.

3.3.1 Basic Operation

The first menu is used for operating the SCU after all calibration and setuphave been completed. This menu has no heading, but starts immediatelywith screen 1.

• SCREEN 1: OUT= 20% - This indicates the output. This displayshows the ammonia feed rate. Otherwise, control output is as previ-ously defined.

When the unit is in the manual mode, pressing ENTER here brings theuser to a submenu. This submenu is where the output may be manually

IM 40.100CB UA (A/1-01)


24

controlled through the UP/DOWN arrows. The DOT or ENTER keysreturn the unit to screen 1.

• SCREEN 2: FLO= 10% - This screen indicates the 4-20 mA inputsignal, which is scaled as required by the FF setting.

When the ENTER key is pressed at screen 2, the user may select “FLO”or “IN” to represent the 4-20 mA input signal. This selection is con-sistent throughout all menus.

• SCREEN 3: AUTO - Here, Automatic or Electric Manual Operationmay be selected. Press ENTER to enter the submenu.

A red LED labeled “AUTO” is located above the keypad. This LEDis on when in the Auto mode, off when in the Electric Manual Mode,and flashes when the actuator knob is out.

• SCREEN 4: DF= 100% - Dosage Factor setting. By pressing EN-TER, the DF value can be scrolled.

• SCREEN 5: FF= 100% - Flow Factor setting. By pressing ENTER,the FF value can be scrolled.

3.3.2 Setup

• SCREEN 1: CODE=? - This screen is displayed only when the SCUis locked. Pressing ENTER allows the user to scroll to the lock code.When the correct code is entered, temporary access is gained, andlocked functions may be entered or changed for a five-minute timeperiod. If the wrong code is entered, the display returns to the top ofthe SETUP menu.

The SCU is shipped with a lock code of 911. This number may alwaysbe used if the user code is lost.

• SCREEN 2: UNLOCKED - By entering, the user may scroll toLOCKED. If ENTER is then pressed, the SCU is locked, and nosettings may be changed without first entering the lock code, as de-scribed above. If any changes are attempted when the SCU is locked,the display flashes CODE ! for two seconds. If left unlocked, screen 1disappears, and the user has access to all functions for unlimited time.

• SCREEN 3: SET CODE - When the SCU is unlocked, pressing EN-TER here displays the existing lock code. The user may scroll to anew code. Pressing ENTER stores the new code into the memory.

IM 40.100CB UA (A/1-01)


25

• SCREEN 4: CONTRAST - Pressing ENTER in this screen allowsthe user to adjust the display brightness by scrolling the contrast num-ber.

3.3.3 Input/Output Setup

• SCREEN 1: REL=ACT - Pressing ENTER in this screen allows se-lection of the function of the relays on the printed circuit board. Thereare three choices:

* ACTUATOR: This allows the SCU to control the position of amotor-operated actuator by applying line voltage to the motor inthe increase or decrease direction.

* PULS/MIN: In this setting, line voltage is pulsed at pin 14, pro-portional to Control Output.

* OFF: This selection disables the relays. This is used if the 4-20mA output is used for control.

• SCREEN 2, ACTUATOR ONLY: SENS=1.0 - Pressing ENTER here,the user scrolls to the desired sensitivity setting, in percent of fullscale output, from 0.1% to 5.0%. This determines the deadband, orthe level of error that causes the motor to correct the actuator posi-tion.

For example, if the sensitivity is 2.0%, the ammonia feed rate feedbackindicates 41% and Control Output is 40%, no correction will be made.If the Control Output goes to 43%, the actuator is moved up until thefeedback is 43%, +2%. If the sensitivity is small or the actuator move-ment is fast, the actuator may occasionally overshoot the setting, ormay oscillate.

Choose a sensitivity setting that avoids oscillation. The SCU comespreset to 1.0% sensitivity. This setting typically operates correctly.

• SCREEN 2, PULSE OUTPUT ONLY: P/M= 100 - Pressing ENTERhere allows the user to select the pulse range, from 30 to 200 pulsesper minute.

• SCREEN 3: mAO= OUT - By pressing ENTER in this screen, themAO can be set as follows: “OUT” represents the ammonia feed rate,or otherwise the control output. “FLOW/IN” represents the input 4-20 mA signal, after scaling by FF. If “OFF” is selected, the 4-20 mAoutput is set to 0 mA.

IM 40.100CB UA (A/1-01)


26

3.3.4 Calibration

• SCREEN 1: FLO CAL - Pressing ENTER here begins the 4-20 mAinput signal calibration. The display indicates “SET 4mA”. When theinput signal is at the zero percent point, press ENTER. The displaythen advances to “SET 20 mA”. Again, press ENTER when the inputsignal is at 100%.

Pressing the “F” key, when either “SET” display is indicated, will skipthat calibration point and allow the user to adjust only one point.Pressing theDOT key at any time, allows the user to escape without making anyfurther changes to the 4-20 mA input calibration. The SCU will rejectcalibration points that deviate too far from typical values.

• SCREEN 2, ACTUATOR ONLY: 2PT CAL - Pressing ENTER atthis point allows the user to select either two- or three-point calibra-tion. For two-point, the actuator is calibrated at 0% and 100%. Forthree-point, the actuator is calibrated at 10%, 50%, and 90%. It isrecommended that calibration is done in order, from lower point tohigher point.

After the number of points is selected with ENTER, the value is stored.

Next, the SCU moves the actuator until the upper feed rate limit isfound, then until the lower limit is found. During this time, the displayflashes, “FIND LIM”, and raw counts are displayed to show progress.Pressing the DOT key at any time, allows the user to escape back tothe calibration menu without saving limit switch or calibration points.Pressing “F” advances to the actuator calibration without changinglimit settings.

NOTE: The SCU detects a limit by sensing no change in actuatorposition for about two seconds. If used with an actuator that movesvery slowly or stalls briefly, it is possible that the SCU may detect alimit early.

By pressing either the up or down arrow, the SCU will continue search-ing for the limit until the button is released.

The SCU steps through the calibration one point at a time, promptingthe user where to set the actuator. For example, “SET 50%” means setthe actuator to 50%, then press ENTER. Any calibration point may beskipped by pressing the “F” key. Pressing the DOT key at any timeallows the user to escape from the actuator calibration without making

27

further changes. The SCU will reject calibration points that deviate too farfrom typical values.

After completing the actuator calibration, the SCU runs a test compar-ing the points entered. If they are not acceptable in relation to oneanother, the SCU will flash the error, ACT CAL. Calibration should berepeated.

• SCREEN 3: mAO CAL - For this calibration, connect a current meterto the 4-20 mA output loop. By pressing ENTER here, the displayreads “SET 4mA”. The user scrolls the UP/DOWN arrows until 4 mAis read on the meter. Pressing ENTER advances the display to the20 mA adjustment. As before, either calibration may be by-passed byusing the “F” key, or the mA output calibration may be canceled bypressing the DOT key.

3.3.5 Diagnostics

• SCREEN 1: SHUTDOWN - By pressing ENTER, the SCU enters asleep mode. The output relays are turned off, the 4-20 mA output isset to 0 mA, and the display flashes “SHUTDOWN”. Pressing anykey returns the SCU to normal operation.

• SCREEN 2: RESET - Pressing enter reboots the SCU.

• SCREEN 3: SET DEF - In case of operating difficulties, the originalfactory default settings may be restored, replacing all user settings,including calibrations. To do this, press ENTER, scroll to “YES”,then press ENTER again.

• SCREEN 4: DISPLAY - Pressing ENTER in this screen performs adisplay test, illuminating all segments of the display for two seconds.

• SCREEN 5: FLO= 8000 - This screen displays the 4-20 mA inputsignal in raw counts, for diagnostic purposes.

• SCREEN 6: FB= 500 - This screen displays the ammonia feedratesignal in raw counts, for diagnostic purposes.

4.1 Routine Service

In the automatic mode, move the actuator to a new position by pulling outand turning the actuator knob. Press the knob back in and verify that theactuator returns to its proper position without oscillating (hunting). Ifoscillation is observed, increase the sensitivity setting. See paragraph 3.3.3.

4.2 Troubleshooting Guide

NOTE: When troubleshooting the unit and before replacing parts, it issometimes possible to restore proper operation by returning the unit tothe factory settings. This is done from the “DIAG” menu, as describedin paragraph 3.3.5. All user settings and calibrations are overwrittenand it is necessary to repeat setup and calibration.

This method of troubleshooting may be used when recalibration fails torestore the unit to normal service.
