EC Sensor Remote Mounting Kit
The remote sensor mounting kit is used to mount the EC sensor
away from the transmitter. To mount the sensor remotely, follow
this procedure:
1. Unscrew the weatherproof cover, loosen the retainer
locking screw and unscrew the sensor retainer.
2. Remove the sensor by pulling (without twisting).
3. Plug the remote sensor cable connector into the bottom of
the transmitter and secure the retainer.
4. Route the cable to the location where the remote sensor is
to be mounted.
5. Optional: make a loop of cable at the junction box. This
will provide some excess for future re-terminations.
6. If necessary, cut the cable to the required length.
Caution: Do not cut the cable too short. Once cut, additional lengths of cable cannot
be added as this will invalidate the intrinsically safe certification.
Warning: Enclosures of remotely mounted sensors contain aluminum. Be careful to
avoid ignition hazards due to impact or friction when installed in Zone 1 locations.
7. Mount the remote sensor junction box, allowing enough
room below to t the sensor and weatherproof cover. See
control drawing 3000E3159 in the Remote Sensor Mount
section for specic mounting information.
