Worcester Controls
Use the UP and DOWN pushbuttons to browse through the main
menu and the sub-menus.
The main menu is divided up into a basic menu, and a full menu.
Other functions:
ESC - Exit the menu without making any changes (as long as any
changes have not been confirmed with OK).
FUNC - To select function and change parameters.
OK - To confirm selection or change of parameters.
MENU INDICATOR - Displays the location of the current menu
row in the menu.
IN SERVICE - The positioner is following the input signal. This is
the normal status when the positioner is working.
OUT OF SERVICE - The positioner is not following the input
signal. Critical parameters can be changed.
MANUAL- The positioner can be adjusted manually using the
push buttons.
UNPROTECTED- Most of the parameters can be changed when
the positioner is in the ‘Unprotected’ mode. However, critical
parameters are locked when the positioner is in the ‘In Service’
mode.
MENU STATUS INDICATORS - On the left side of the display there
are indicators that mean the following:
Top Left (on and flashing) - OUT OF SERVICE
Middle Left (on and flashing) - MANUAL MODE
Bottom Left (on) - UNPROTECTED MODE
Calibration
The following steps are used to calibrate the unit for verification of
installation. Specific programming and advanced features are
explained in the Technical Reference Manual (Part No. 19990).
1. Apply 80 psig air to the supply ‘S’ port of the positioner.
2. Set the input signal source to 10–12 milliamps.
3. Look at the display- it should read “BASIC MENU” over
“CALIBRATE”
4. Momentarily depress the pushbuttons in the following sequence
to begin the auto-calibration routine.
FUNC, FUNC, OK, OK, OK, OK, OK
5. At this point, the positioner will begin it’s auto-calibration
routine.
Note: If the display reads ‘increase C+ damper’, there is too much air
volume flowing to the actuator (speed is too high). Adjust the
damper by turning the C+ damper screw clockwise

turn and press
the ‘ok’ button. Refer to the inside electrical cover for location of the
C+ damper screw. Adjust until the unit performs the auto-calibration
routine without getting the ‘increase C+ damper’ message.
6. For double acting actuators, both the ‘C+’ and ‘C-’ damper
screws may need adjusting. Follow the display instructions
accordingly.
7. At the end of the auto-calibration routine, press and hold the OK
pushbutton for three seconds to place the unit back to ‘IN
SERVICE’.
8. If an internal leak is detected during the auto-calibration
routine, the display will show ‘AIR LEAK DETECTED’. The next
screen will show ‘ESC=ABORT’ and ‘OK=GO ON’. Press the ESC
to stop the calibration routine or OK to allow you to continue
the calibration and ignore the leak.
9. When the unit is back ‘IN SERVICE’, the positioner should
respond to the 4–20 mA input signal with 4 mA= Full CW and 20
mA=Full CCW positions.
4–20 mA Output Option Calibration
Attach a current meter (4–20 mA range) in line with the positive
meter lead connected to terminal strip position 12, the negative
meter lead connects to the negative power supply (10–28 volts DC)
lead, and the positive power supply lead connects to terminal strip
position 11.
1. Turn on the ammeter and power supply.
2. Press and hold the ESC pushbutton for three seconds to get the
display back to the root menu. Display should show ‘BASIC
MENU’ over ‘MAN/AUTO’.
3. Press the DOWN button twice and display should read ‘BASIC
MENU’ over ‘SHIFT MENU’.
4. Press the FUNC button once and display should read ‘Full menu’
over ‘no’.
5. Press the DOWN button and display should read ‘Full menu’
over ‘yes’.
6. Press the OK button and display should read ‘FULL MENU’ over
‘SHIFT MENU’.
7. Press the DOWN button four (4) times and display should read
‘FULL MENU’ over ‘TUNING’.
8. Press the FUNC button and the display should read ‘TUNING’
over ‘Close time’.
9. Press the DOWN button three (3) times and display should read
‘TUNING’ over ‘Expert’.
10. Press the FUNC button once and the display should read ‘Expert’
over ‘togglestep’.
11. Press the DOWN button three (3) times and the display should
read ‘Expert’ over ‘Ref Cal’.
12. Press the FUNC button once and the display should read ‘Ref
Cal’ over ‘Set point’.
13. Press the DOWN button four (4) times and the display should
