6.3.18 Replacing a Remote T/H Sensor (33010516)
Prerequisites
● A T/H sensor needs to be replaced.
● A spare T/H sensor of the same model is available and functional.
Context
A T/H sensor can be maintained only from the rear door.
Procedure
Step 1 Tap Shutdown on the controller home screen.
Exercise caution because the device is still energized after it is shut down on the
controller home screen.
Step 2 Remove the cables from the T/H sensor.
After removing cables, wrap exposed terminals with insulation tape and do not
block cable labels. If cable labels are blocked, cables may be connected incorrectly
later.
Step 3 Remove the faulty T/H sensor.
Step 4 Attach the new T/H sensor to an appropriate position on the IT cabinet door
frame based on site requirements.
Step 5 Reinstall the cable removed from the T/H sensor.
Before removing a T/H sensor, remember the DIP switch setting on it. When you install a
new T/H sensor, you need to set the same DIP switch setting for the new one.
