15.2 Serviceable sensor cell replacement
Caution: For toxic sensors, remove the shorting clip from the bottom
of the sensor prior to installation. For O2 sensor, there is no shorting clip provided.
Caution: There are two types of sensor cap - teon coated (black) and stainless steel.
Ensure that a teon coated sensor cap is retted for S3KXSF1SS (HF), XSZ1SS (O3),
and XSR1SS (HCl) cells.
The serviceable sensor allows replacement of the cell inside the sensor. The cell can only be replaced
with the same type cell. To replace the cell follow the procedure below.
1. Enter the change sensor menu (see section 12).
2. Unscrew the weatherproof cover, loosen the sensor retainer locking screw and unscrew the sensor retainer.
3. Remove the old sensor by pulling without twisting.
4. Unscrew the sensor cap.
5. Remove the old cell by pulling without twisting.
6. Ensure the new cell is the same type as the old cell.
7. Plug the new cell into the sensor, taking care to align the sensor pins with the connector holes in the pcb.
8. Ret the sensor, taking care to align the sensor pins with the connector.
9. Ret the sensor cap, ensuring that it is the correct type. Ret the sensor retainer, tighten the locking
screw and ret the weatherproof cover.
10. Countdown time of up to 180 seconds (dependant on sensor type) is displayed.
11. Re-Calibrate the detector following the procedures in section 8.2.
