To withdraw the Digital Controller Programmer from its housing, simply grip the side
edges of the front panel (there is a finger grip on each edge) and pull the panel
forwards. This will release the Digital Controller Programmer from its rear
connectors in the housing and will give access to the PCBs. Take note of the
orientation of the Digital Controller Programmer for subsequent replacement into
the housing.The positions of the PCBs are shown in Figure 3-1.

3.2 REMOVING/REPLACING THE OUTPUT 2/OUTPUT 3
OPTION PCBs
With the Digital Controller Programmer removed from its housing:
1. Gently push the rear ends of the CPU PCB and Power Supply PCB apart
slightly, until the two tongues on each of the Output 2/Output 3 Option PCBs
become dis-engaged - see Figure 3-2B; The Output 2 Option PCB tongues
engage in holes in the Power Supply PCB and the Output 3 Option PCB
tongues engage in holes on the CPU PCB.
2. Carefully pull the required Option PCB (Output 2 or Output 3) from its
connector (Output 2 Option PCB is connected to the CPU PCB and Output 3
Option PCB is connected to the Power Supply PCB) - see Figure 3-2C. Note
the orientation of the PCB in preparation for its replacement.
Adjustments may now be made to the link jumpers on the CPU PCB, the Output
2/Output 3 Option PCBs (if DC output) and (if fitted) the DC Output 1 PCB. The
replacement procedure is a simple reversal of the removal procedure.
3.3 REMOVING/REPLACING THE RS485
COMMUNICATIONS OPTION PCB
The RS485 Communications Option PCB is mounted on the inner surface of the
Power Supply PCB and can be removed when the Digital Controller Programmer is
removed from its housing (see Subsection 7.1) Figure 3-3 illustrates the
removal/replacement procedure. It is not necessary to remove the Output
2/Output 3 Option PCBs to perform this procedure.

3.4 INSTALLING/REMOVING THE DIGITAL INPUT OPTION
PCB
The location of the Digital Input Option PCB is shown in Figure 3-4. It is connected
to the CPU PCB via a flexi-strip connector, as shown.
To install the Digital Input Option PCB:
1. Hold the PCB ap proxi mately in po si tion and care fully in sert the free end
of the flexi- strip ca ble into the socket near the bot tom edge of the CPU PCB
(en sur ing that none of the pins on the end of the flexi- strip be come bent
and that the flexi- strip is not twisted).
2. Fully in sert the Digi tal In put Op tion PCB into its con nec tor at the rear of
the front panel (when the PCB is fully in serted, it will be come en gaged in
