CONCISE PRODUCT MANUAL (59333-2)
CAUTION:
Installation should be only performed by
technically competent personnel. Local Regulations
regarding electrical installation & safety must be observed.
1. INSTALLATION
The models covered by this manual have three different DIN case sizes (refer to
section 9). Some installation details vary between models. These differences have
been clearly shown.
Note: The functions described in sections 2 thru 8 are common to all models.

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.

These diagrams show all possible option combinations. The actual
connections required depends on the exact model and 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
Note: At first power-up the message
is displayed, as described in
section 6 of this manual. Access to other menus is denied until configuration
mode is completed
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.

3. CONFIGURATION MODE
First select Configuration mode from Select mode (refer to section 2).
Press to scroll through the parameters, then press or to set the required
value. Press to accept the change, otherwise parameter will revert to previous
value. To exit from Configuration mode, hold down and press , to return to
Select mode.
Note: Parameters displayed depends on how instrument has been configured.
Refer to user guide (available from your supplier) for further details.

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 used 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.
