panel mounted indicator. It will provide accurate measurement and display of
temperature and other process variables. A modular build accepts a wide range of plug-in modules allowing: up
to four alarm outputs, two process variable (PV) inputs, direct strain gauge/pressure sensor measurements,
custom linearisation, analogue retransmission, remote setpoint (SP) input and digital communications.
The indicator is supplied configured in accordance with the order code. The order code and instrument serial
number is shown on a label fixed to the top of the case, and this can be checked against the order code given in
section 5 of these instructions.

To Install the Indicator
Please read the safety information in section 6 before proceeding.
The indicator is intended to be mounted on a panel within an enclosure such as a control cubicle.
1.
Prepare the panel cut-out to the size shown.
2.
Fit the sealing gasket behind the front bezel of the instrument.
3.
Insert the indicator in its sleeve through the cut-out.
4.
Spring the panel retaining clips into place. Secure the indicator in position by holding it level and pushing
both retaining clips forward.
5.
Peel off the plastic film protecting the front of the indicator.
1.2.2
Removing The Indicator From The Sleeve
W
The indicator can be removed from its sleeve by easing the latching ears outwards and pulling it forward out
of the sleeve. When plugging the indicator back into its sleeve, ensure that the latching ears click into
place to maintain the moisture sealing protection.
It is recommended that power to the controller is turned off when removing or replacing the controller into
its sleeve, to prevent premature wear on the connectors when current is flowing through them.
