the slots above and be low its con nec tor).
To remove the Digital Input Option PCB:
1. Dis- engage the PCB from its slots (above and be low the con nec tor at the
rear of the front panel) and with draw the PCB clear of the con nec tor.
2. Dis con nect the flexi- strip from the con nec tor near the bot tom edge of
the CPU PCB.
3. Re move the Digi tal In put Op tion PCB com pletely from the in stru ment.

Figure 3-4 The Digital Input Op tion PCB and Event Output Option PCB3.5 INSTALLING/REMOVING THE EVENT OUTPUT OPTION
PCB
The location of the Event Output 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 Event Output 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 top 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 Event Out 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
the slots above and be low its con nec tor).
To remove the Event Output Option PCB:
1. Dis- engage the PCB from its slots (above and be low the con nec tor at the
rear of the front panel) and with draw the PCB clear of the con nec tor.
2. Dis con nect the flexi- strip from the con nec tor near the top edge of the
CPU PCB.
3. Re move the Event Out put Op tion PCB com pletely from the in stru ment.
3.6 REPLACING THE DIGITAL CONTROLLER PROGRAMMER
IN ITS HOUSING
To replace the Digital Controller Programmer, simply align the CPU PCB and Power
Supply PCB with their guides and connectors in the housing and slowly but firmly
push the Digital Controller Programmer into position.
CAU TION: En sure that the in stru ment is cor rectly ori en tated. A stop will
op er ate if an at tempt is made to in sert the in stru ment in the wrong
ori en ta tion (e.g. upside- down). This stop must not be over- ridden.
3.7 SELECTION OF INPUT TYPE
The se lec tion of in put type is ac com plished on link jump ers LJ1/LJ2/LJ3 on the CPU
PCB (see Fig ure 3-5 and Ta ble 3-1).
