Description
S1
Battery isolation switch. Isolate battery before transportation.
Table 15 – PSU Board Switches
4.6.5 Changing
Fuses
See section 7.3.5 for fuse change procedure.
4.6.6 PSU Board address
The PSU board is a GSPI peripheral and as such is addressed in the normal way as an
I/O board. The address is fixed at 15 and is not user selectable.
Address 15 must not be used by any other GSPI peripheral if a PSU board is
present in the system.
4.6.7 Replacing a faulty PSU board
The PSU board is not considered to be a field replaceable part as the unit needs to be
fully disassembled to replace it. If the PSU board is thought to be faulty, return the
complete unit for repair.
4.7
Inbuilt
Backup Battery
The inbuilt sealed lead acid backup battery should be replaced as routine maintenance
typically every 3-5 years under normal circumstances to ensure that the backup time is
adequate for instation communications during a power failure. The battery test (see
below) can be used to determine exactly when to replace the battery.
If the application demands backup at extremes of temperature (outside -20°C to +60°C),
then an external battery can be connected to the Power supply board via the rear 10 way
connector. If this option is used, note that:
1. The internal battery
MUST
be disconnected. Unplug and/or remove the internal
backup battery as described in section 7.3.4.
2. Any external battery
MUST
be a lead acid type and 12V.
3. The external lead acid battery is should be connected to the General Functions
connector, negative to pin 9, Positive to pin 10 – refer to Table 13.
4. An external battery
MUST
be fused externally with an in-line fuse holder and 5A
quick blow fuse.
5. The internal battery charger will charge an external lead acid battery.
6. There is no limit to the size/capacity of any external battery. The system firmware
will automatically shut the system down after 1 minute following a power failure so
there is no benefit in increasing external battery capacity above the capacity
required for 1 minutes running at the system load and with minimum operating
temperature in mind (where battery capacity is reduced).
