To initiate zero calibration from the OPECL:
1. Using the magnet, activate the magnetic calibration
switch on the OPECL receiver. See Figure below.
The green LED will turn red.
2. The UD10-DCU will display “Waiting for Zero” on
the main display screen, with a solid red LED on the
OPECL housing illuminated.
3. After the calibration is successfully completed,
the UD10-DCU automatically returns to the normal
display with the green LED illuminated on the OPECL
housing.

If the OPECL system experiences a Transmitter (Tx)
Lamp Fault condition, the UD10-DCU display will not
indicate a fault condition and its output will remain at 4
mA. The OPECL system is still fully functional and able
to detect gas. If a gas alarm condition should occur,
the alarm condition will override the Tx Lamp Fault
condition.
The OPECL system indicates a fault condition by
amber indicator LEDs on both the transmitter and the
receiver.
To verify an OPECL Tx Lamp Fault condition, within the
Menu Structure of the UD10-DCU Display navigate to
the device Fault/Status menu:
The Fault status will indicate Y (Yes). Click on “Fault”
and the Fault menu will identify the fault as a “Lamp
Fault”.
For complete information regarding OPECL fault
indications and operation of the OPECL transmitter
lamps, refer to the OPECL instruction manual, number
95-8556.
