purpose is to detect and shutdown the module in the event of flame detection. The following alarms
may be displayed on the AP11 controller:
UA-17 UVIR fault alarm. In addition to the fault alarm displayed on the AP11 controller, the UVIR
detector will illuminate one LED to visually indicate a fault. Faults may include temperature,
excessive input voltage, low input voltage, no power, detector fault, relay fault, self-checking fault,
analog “0” current. Descriptions of these fault alarms can be found in the UVIR Detector appendix
section of this manual.
RSHH-17 UVIR flame detect. If a flame is detected for more than 5 seconds at the module, the UVIR
detector will send a shutdown signal. Upon receipt of this shutdown signal through a hardwired input,
power is removed from the J-T heater and heat trace, all valves are closed and process gas flow stops.
This would cause and interruption of process gas flow to the customer.
RSHH-18 is Optional
It is the UVIR Detector viewing Source A2. This UVIR detector is mounted
and positioned in the field to view the source container connection. Its purpose is to detect and
shutdown the module in the event of flame detection. The following alarms may be displayed on the
AP11 controller:
UA-18 UVIR fault alarm. In addition to the fault alarm displayed on the AP11 controller, the UVIR
detector will illuminate one LED to visually indicate a fault. Faults may include temperature,
excessive input voltage, low input voltage, no power, detector fault, relay fault, self-checking fault,
analog “0” current. Descriptions of these fault alarms can be found in the UVIR Detector appendix

RSHH-19 is Optional
It is the UVIR Detector viewing Source B2. This UVIR detector is mounted
and positioned in the field to view the source container connection. Its purpose is to detect and
shutdown the module in the event of flame detection. The following alarms may be displayed on the
AP11 controller:
