3 Troubleshooting and Test Functions
Module Type Changed
At switch-on, the detector has recognized a new configuration. Only G1315B
and G1365B detectors have built-in hardware for temperature control. The
type of the module changed from A to B or vice versa because the hardware
for the temperature control was either detected or not detected.
The parameter of the event determines the new module type:
Look at the product identifier to check if your detector is of type A (G1315A or
G1365A) or B (G1315B or G1365B) and proceed accordingly.
Type A, Parameter 0 or 2
Probable Causes
• Main board has been exchanged
Suggested Actions
✔ Power cycle the detector
Type B, Parameter 0 or 2
Probable Causes
• Defective or missing heater connector
Suggested Actions
✔ Ensure the connector to the detector main board is seated firmly and power
cycle the detector. At next switch-on you will get the same error message,
but with parameter 1 or 3 because the temperature hardware is detected
again (see below).
0 means G1315 no temperature hardware detected
1 means G1315 temperature hardware detected
2 means G1365 no temperature hardware detected
3 means G1365 temperature hardware detected
