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.

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 !"#" $"%& is displayed, (see section 6).
Access to other menus is denied until configuration mode is completed

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.

Exceed Condition
An Exceed Condition is when the Process Variable exceeds the Limit Setpoint value
(i.e. PV > SP when set for high limit action, PV < SP for low limit action). The
LED is on during this condition, and is extinguished once it has passed.
Limit Output Function
Limit Output relay(s) de-energise whenever an Exceed condition occurs, causing
the process to shut down. The LED is on when the relay is de-energised.
The relay remains latched off even if the Exceed condition is no longer present.
Only giving a reset instruction (after the exceed condition has passed) will re-
energise the relay, allowing the process to continue. The LED then turns off.
Limit Annunciator Outputs
An Annunciator output will activate when an Exceed condition occurs, and will
remain active until a reset instruction is received, or the Exceed condition has
passed. Unlike the Limit Output, an Annunciator can be reset even if the Exceed
condition is present. When an Annunciator is active, the LED will flash and the
Alarm Status screen is available.
Resetting Limit Outputs & Annunciators
A reset instruction can be given by pressing the key, via the Digital Input (if
fitted) or via a Comms command if an RS485 Communications module is fitted.
Annunciators will deactivate. Limit Outputs will only re-energise if the Exceed
condition has passed.
CAUTION: Ensure that the cause of the Exceed condition has been
rectified before resetting the Limit Output.
