5.3 Installing the sensor
WARNINGS
Care should be taken when removing and refitting the Sensepoint XCD plug-in Sensor to
the Sensor Socket so that damage to the connection pins can be avoided.
If using an anti-seize compound, the threads should be thinly coated with an approved
silicone free compound e.g. petroleum jelly
Take care when handling old sensors as they may contain corrosive solutions.
Take care when removing or replacing the Sensor Retainer as there may be sharp edges
present on the adjoining threads.
The equipment is designed and constructed as to prevent ignition sources arising, even in
the event of frequent disturbances or equipment operating faults.
Only assessed for ATEX for ignition hazards.
The sensor head must be fitted with the supplied weather protection, and mounted so that
the sinter is pointing downward to provide ingress protection IPX6.
The weather protection is a potential electrostatic charging hazard. The manufacturer’s
instructions should be observed.
A remotely mounted sensor should be mounted using a suitable junction box . For further
details regarding mounting sensors to suitable junction boxes refer to the relevant sensor
manual.
1. Connect the remote sensor/junction box to the Sensepoint XCD RFD transmitter
using suitable cable with wires of diameter 0.5 - 2.5mm
2
(20AWG - 13AWG).
2. Connect the cable to the transmitter enclosure via the bottom entry.
3. Cable (non conduit) based installations must use appropriately certified cable glands.
Refer to the Sensepoint XCD RFD Control Drawing 3001EC091 shown in section 17
for conduit based installation in the Americas.
Note: The maximum cable length between the remotely mounted sensor and the
Sensepoint XCD RFD transmitter is 30 meters (100 feet). The maximum loop
resistance is 17 Ω.
4. Terminate the wires from the sensor in the transmitter as shown in chapter 6.2.
5. Select sensor type at configuration menu after remote sensor mounting. Refer to the
chapter 12.1 Sensor Replacement and the chapter 13.3.1 Sensor Selection.
