SENSOR, ALARM AND OUTPUT CABLE CONNECTORS:-

To open the spring clamp terminals, EITHER:-

Inseli a flat bladed screw-driver into the rectangular slot, above the cable entry

and twist it through 90°. This forces the cage open and the cable can be inserted

through the round hole.

Twist the screw-driver back through 90° and extract it from the rectangular slot,

to clamp the cable.

Only if the cable connector has been unplugged from the instrument, lay the

connector on a flat surface and push down on the upper section of the spring

clamp which is visible through the slot in the top of the connector. This forces the

cage open and the cable can be inserted through the round hole.

Remove the downward pressure on the spring clamp to clamp the cable.

SENSOR CABLE

Connect the sensor cable to the lower left 5 pin connector, ensuring that the correct

colour coding is observed and that the cage is securely clamped onto the bootlace ferrules

on the cable provided.

Root the sensor cable to the intended site of the sensor.

NOTE

Do not install the sensor at this time. Wait until the commissioning stage,

as described on page 9.

ALARM CABLE

Make the appropriate connections, noting the normally open and normally closed relay

contact positions.

ANALOGUE OUTPUT CABLE

Make the appropriate cOlmections, ensuring that the correct polarity and the maximum

load specification is strictly observed.

As can be seen from the label, the output can be used in either ACTIVE or PASSIVE

mode and it is impOliant that the correct option is used, to ensure normal operation of the

output system.
