Probe connections, general

WARNING
Bodily injury.
• Before making any connections, ensure that the power
supply, any high voltage-operated control circuits and
high common mode voltages are switched off.
Perform the procedures detailed below.
A 4 mm earth bonding point is provided on the back of the
probe head – see Figure 11.

Access to probe terminals

Referring to Figure 13:
1 Release 2 captive screws
and remove the terminal cover.

Preparing the cable(s)

The cable(s) must be prepared to suit the non-AutoCal/AutoCal
systems before connections can be made.
Cable requirements:
• one length of 14-core cable is required to connect
non-AutoCal systems (probe to transmitter) –
maximum length 100 m (300 ft).
• two lengths of 14-core cable are required to connect
AutoCal systems (probe to AutoCal unit and AutoCal unit
to transmitter) – maximum combined length 100 m
(300 ft).
Refer to the following pages for connection requirements:
• page 19 for non-AutoCal systems (probe to transmitter)
• page 21 and page 22 for AutoCal systems
(probe to AutoCal unit and AutoCal unit to transmitter)

Cable glands

NOTICE
The special EMC cable gland supplied with the probe/
transmitter can be replaced by any 1/2 in NPT or 1/2 in BSP,
EMC metal gland that forms a watertight seal on the outer
sheath of the cable and an electrical contact to the braided
copper shield.
The gland must form a good electrical contact with the
probe for grounding purposes and form a NEMA 4X
watertight seal with the probe – see Figure 10, page 14.
