XV. CALIBRATION
1. Valve Position Calibration (UBEC1, UBEC2, UBEC3, UICS2)
All valves must have the position calibrated after installation.
The program has to be calibrated for the voltage level at both full closed and full open position of the valve.
After the 2 valve positions are calibrated, the program will check to make sure that the voltage levels are
within normal limits.
If they are not, an alarm will be generated to indicate a system failure:
UBEC1 will flash the red CLOSED and green FULLY OPEN LEDs.
UBEC2, UBEC3, and UICS2 will show an F1 in the pressure display.
NOTE: The valve should be partially open before starting valve position calibrationl.
Set Fully Closed Position
1. Press and hold the CLOSE and PRESET buttons. Release both buttons when the red CLOSED LED
starts to flash.
2. Use the CLOSE button to close the valve.
3. When the valve is fully closed (detected by a high current surge when the valve hits the positive stop),
the CLOSED LED will flash at a faster speed.
4. Press and hold the PRESET (CAF SELECT for UICS2) button for 5 seconds to accept and exit the
calibration. Red LED will stop flashing.
Set Fully Open Position
1. Press and hold the OPEN and PRESET buttons. Release both buttons when the last green LED in the
fully opened window starts to flash.
2. Use the OPEN button to open the valve.
3. When the valve is fully opened (detected by a high current surge when the valve hits the positive stop),
the last fully opened LED will flash at a faster speed.
4. Press and hold the PRESET (CAF SELECT for UICS2) button for 5 seconds to accept and exit the
calibration.
2. Automatic Valve Position Calibration (E3F, E4F, E5F, & E6F)
All valves must have the position calibrated after installation.
NOTE: The valve should be partially open before starting valve position calibrationl.
The automatic calibration routine has been added to further simplify the calibration of the open and closed
positions of the valve. After initiating the calibration routine, the valve will automatically travel completely
closed. After setting the closed position, the valve will automatically travel completely open. The valve is
then returned to the completely closed position at the end of the routine. The routine can be enabled with
the use of any type of valve controller.
UBEC
The automatic calibration can be activated with the use of any UBEC controller. This routine can be
initiated by pressing and holding the CLOSE and PRESET buttons for 5 seconds. This routine can also be
initiated by pressing and holding the OPEN and PRESET buttons for 5 seconds.
External Switches
The automatic calibration routine can be activated through the use of external switches by pressing and
holding the CLOSE and PRESET switches for 5 seconds. This routine can also be initiated by pressing and
holding the OPEN and PRESET switches for 5 seconds.
No Controller
The automatic calibration routine can be activated without the use of any controller. This can be
accomplished by supplying a 12 or 24 VDC signal to PIN 5 on the 12-pin connector for 10 seconds. Please
refer to the Wiring section on Page 68 for further details.
