PSU LED INDICATIONS
The power supply continuously monitors the AC supply, the battery connection, the battery charging voltage,
and the output supply voltage. It will bring up the appropriate Fault conditions if these are outside of
specifications. These faults will be indicated by the respective LEDs on the Power Supply PCB
– see Figure

PSU LED Indications
1.8.4.2
PSU FAULT INDICATIONS
◼
AC Fault
The AC Fault LED, Supply Fault Relay and General Fault Relay activates. When the Fault is cleared,
indications and relays restore immediately.
◼
Earth Fault
The Earth Fault LED and General Fault Relay activates. When Fault is cleared, indications and relay
restore within 30 seconds.
◼
Charger Fault
The Charger Fault LED and General Fault Relay activates. When the Fault is cleared, indications and
relay restore within 30 seconds.
◼
Battery Fault
The Battery Fault LED and General Fault relay activate. When the Fault is cleared, a panel reset or hard
reset on the PSU is required to restore indications and relays, or alternatively the fault will clear once a
successful load test was complete.
◼
Output Fault
The maximum continuous operating output current is 1.2 A. Should you exceed 1.2 A, three modes are
provided to protect the output or to provide additional current, depending on the amount of current draw.
▪
Boost Mode
‒
Should the current draw exceed 1.2 A, the 27.5 V DC output Fault LED will flash, and the
battery charger circuit will be shut down.
‒
If the 27.5 V DC output current draw exceeds 1.2 A, but is less than 1.8 A, for more than
10 minutes, the General Fault Relay and the 27.5 V DC output LED will be on solid.
The Charger Fault LED will also be solid on to indicate the charger is still off due the additional
current drawn on the output.
‒
The 27.5 V DC output remains active.
‒
When current draw is reduced to below 1.2 A, LED indications, relay and charger will restore
automatically within 30 seconds.
▪
Overload Mode
‒
Should the current draw exceed 1.8 A, the 27.5 V DC output Fault LED will flash, and the
battery charger circuit will be shut down.
‒
If the 27.5 V DC output current draw exceeds 1.8 A, but is less than 2.5 A, for more than
10 minutes, the General Fault Relay and the 27.5 V DC output LED will be on solid.
‒
The output will shut down and attempt to restore every 30 seconds; this will continue until the
load is reduced to below 1.8 A.
‒
The charger will switch back on automatically.
‒
When current draw is reduced to below 1.8 A, the 27.5 V DC output will restore automatically
after 30 seconds into BOOST MODE condition. The general fault relay will remain on.
‒
When current draw is reduced to below 1.2 A, the relay and charger will restore automatically
within 30 seconds. The Output Fault LED will be solid on and requires a hard or soft reset to
clear.
