Figure 77: Catalytic latch reset
NOTE
There may be several status titles displayed, which correspond to the
catalytic latch event e.g. FULL SCALE LOCK, SETPOINT FLAG SET
and READING OVER RANGE.
4. The display will return to the menu without showing a confirmation. Once the latch is successfully
reset, the gas reading should again reflect the actual gas value and the status flags shall in turn
become unset.
LED Indicator Test
The LED indicator test can be used to verify the function of the three LED indicators on the GG2 Display.
The test sequence should be as follows:
1. One LED flashes several times, this repeats for the other LEDs, after which the cycle repeats.
This should happen approximately four times per LED.
2. The three LEDs should then flash together with increasing frequency until the end of the test.
3. On completion, the menu is displayed.
The behaviour of the LED test cannot be ensured when the fault/alarm LEDs are flashing due to alarm or
fault
