Replacing a
Sensor
If a damaged sensor needs to be replaced then the cover of the
enclosure will need to be opened unless the choice is made to join
the wires externally (see Lengthening Sensor Wire section above).
1. Remove the mains power supply. Make sure no other power
source is feeding back through other connections.
2. Remove the 4 screw covers on each corner of the lid of the
enclosure. This will require a fine tipped tool such as a screw
driver. Be careful not to damage the lid. Always press the tool
away from you to avoid injury if you slip.
3. Remove the 4 screws that hold the lid on.
4. Unscrew the damaged sensor from the terminal block.
5. Loosen the cable clamp for the sensor leads.
6. Carefully pull the wire back through the opening in the bottom
case.
7. Thread the new sensor wire back through where the old one
came from.
8. Place the wires of the new sensor into the terminal block where
the old sensor came from and retighten the screws.
