5.8 Processor PCB
The ID3000 Series Processor PCB controls and monitors
all ID3000 Series Control Panel processing functions.
The Processor PCB is electrically connected to the
Display PCB and the Base PCB. The Processor PCB
(PN: 124-360) engages a 64-way socket on the right-
hand edge of the Base PCB and is held in place with two
M3 x 8 SEM screws. Connection is provided to the
Display PCB via a 34-way ribbon cable.
In the unlikely event that the Processor PCB needs
replacing, follow the procedure described below using
the PCB supplied as part of a spares kit (PN: 020-569).
Before starting, make sure you have a PC back-up of
the panel’s current configuration data.
Ensure you take appropriate anti-static precautions
before undertaking this procedure.
1
With the front cover moulding(s) removed
and all
power disconnected
, proceed as follows:
2
Using a suitable-sized coin, release the two
quarter-turn fasteners (A) located at the left-hand side
of the main chassis front door (B). Open the door to
gain access to the main chassis’ PCB enclosure (C).
3
On the Processor PCB (D), at socket J2, disconnect the
34-way ribbon cable (E) from the Display PCB (F). Third
layer PCB(s) if fitted, have to be removed at socket J6.
Note:
If applicable, the wiring on the upper edge of the
Processor PCB may have to be disconnected.
4
Using a No.1 Posidriv screwdriver, remove the two M3 x
8 SEM screws located in the two right-hand corners (G)
of the Processor PCB and place in an anti-static bag.
Note:
The Processor PCB is held in position until
withdrawn from the 64-way socket on the Base PCB.
5
Using a constant and firm pulling action, withdraw the
Processor PCB from the main chassis PCB enclosure
and place in an anti-static bag.
6
With the replacement Processor PCB correctly orientated
(see lower drawing), offer the PCB to the right-hand edge
socket SK1 on the Base PCB. Ensure the connector
J5 cleanly engages the Base PCB socket SK1. Once
in position, replace the two screws (G) and secure.
7
Re-connect the 34-way ribbon cable between the
Processor PCB and Display PCB.
8
Close the main chassis front door. Re-connect mains
power and the batteries. If no faults exist, the following
message is displayed in the bottom left-hand corner
of the LCD:
*UNCONFIGURED*
9
If no faults exist, use the Off-line Configuration Program
to download your previous system configuration data.
If any faults exist, consult the ID3000 Series Operating
Manual (ref. 997-505-000-X), or your supplier if the
problem persists.
10
If panel status is normal, replace the front cover
moulding(s).

Make sure you have a PC
back-up of the current
configuration data.
WARNING - Disconnect
ALL power from the ID3000
Series panel.
CAUTION - To avoid a
system fault only use panel
software version 4.6x, or
later.
