UNIVERSAL DIGITAL CONTROLLER PRODUCT MANUAL (51-52-25-123-EN)
CAUTION: Installation should be only performed by
technically competent personnel. Local Regulations
regarding electrical installation & safety must be observed.
1. INSTALLATION
Models UDC1200 and UDC1700 have different case sizes (refer to section 10).
Installation differences between these models the have been clearly shown.
Note: The functions described in sections 2 thru 9 are common to all models.

To access modules 1, A or B, first detach the PSU and CPU boards from the front b
y
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 7 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.

there is no key activity for 2 minutes.
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.
