CAUTION:
Installation should be only performed by
technically competent personnel. Local Regulations
regarding electrical installation & safety must be observed.
1. INSTALLATION
Installing Option Modules
CPU PCB
Option Module 1
(Fixed Limit Relay)
Option Module 2
Mounting Struts
Option Module A
Option Module 3
PSU PCB
To access module A, first detach the PSU and CPU boards from the front by lifting
first the upper, and then lower mounting struts. Gently separate the boards.
a.
Plug the required option modules into the correct connectors, as shown below.
b.
Locate the module tongues in the corresponding slot on the opposite board.
c.
Hold the main boards together while relocating back on the mounting struts.
d.
Replace the instrument by aligning the CPU and PSU boards with their guides
in the housing, then slowly push the instrument back into position.
Note: Option modules are automatically detected at power up.

Ratchets
Gasket
Slide mounting clamp
over the instrument
housing towards rear face
of mounting panel until
the tongues engage in
ratchets and instrument is
clamped in position.
Hold instrument firmly in
position (apply pressure
to bezel only)
CAUTION:
Do not remove the panel gasket; it is a seal against dust and
moisture.
Rear Terminal Wiring
USE COPPER CONDUCTORS (EXCEPT FOR T/C INPUT)
Single Strand wire gauge: Max 1.2mm (18SWG)
Actual connections required depend on the options fitted.
CAUTION:
Check information label on housing for correct operating
voltage before connecting supply to Power Input
Fuse: 100 – 240V ac – 1amp anti-surge
24/48V ac/dc – 315mA anti-surge
2. SELECT
MODE
Select mode is used to access the configuration and operation menu functions.
It can be accessed at any time by holding down and pressing .
In select mode, press or to choose the required mode, press to enter.
An unlock code is required to prevent unauthorised entry to Configuration, & Setup
modes. Press or to enter the unlock code, then press to proceed.
Note: At first power-up the message
!"#"

Notes: Output 1 is always a Latching Limit Relay output.
If Option Slot A has the Digital Input module fitted, this always functions as a
Remote Reset, duplicating the function of the Reset) key .
As these functions cannot be changed, no Configuration menus are required.
CAUTION:
Process Variable Offset can be use to modify the measured
value to compensate for probe errors. Positive values increase the
reading, negative values are subtracted. This parameter is effectively,
a calibration adjustment and MUST be used with care.
There is no front panel indication of when this parameter is in use.
4. SETUP
MODE
Note: Configuration must be completed before adjusting Setup parameters.
First select Setup mode from Select mode
(refer to section 2).
The Setup LED
will light while in Setup mode. Press to scroll through the parameters,
then press or to set the required value.
To exit from Setup mode, hold down and press to return to Select mode.
Note: Parameters displayed depends on how instrument has been configured.

CAUTION:
An excessively large filter time could significantly delay
detection of a limit condition. Set this value to the minimum required
to remove noise from the process variable
