Status Message:
“Locked Out - Fan”
Relay is waiting for fan
interlocking system.
If interlocking is not required then a 10k
ohm resistor must be connected
between terminals 9 and 12.
If fan interlocking is used ensure that
the fan is running and the current
threshold setting in the fan outlet’s RTU
is correct.
The Fan Outlet IPD should pick up its
FID (Fan Interlock Drive) signal, which
causes all other relays to pick up their
FIR (Fan Interlock Read). Check these
conditions level 6, position 4.
If fan interlocking is not correct check
the wiring between the fan relay and
other relays (terminal 9).
Relay displays ‘Outlet Close Fail’
message after start is pressed.
The relay’s MCI input is
not closing within 5 Sec of
MCR relay pickup (level 6
position 2).
Check that main contactor is closing. If
not check circuit or replace main
contactor.
RDM displays ‘Tripped-No Volts’
message.
Relay not receiving/lost
voltage feedback on one or
all three outlet phases
when contactor closed.
Check system voltage display (level 4,
position 1) as contactor closes.
Compare this with the under voltage
threshold.
Check continuity from the relay,
through the CCMD to power
conductors. This can be achieved by
testing each phase to earth at the
outlet, provided the circuit is isolated.
Typical readings:
CCMD-415 2340k ohm
CCMD-1000 2340k ohm
CCMD-3.3k 7520k ohm
Relay Trips on MCF on power
up.
Main Contactor Fail
condition.
Check main contactor for leakage
across terminals on frozen contactor
condition.
Return to Ampcontrol for battery
replacement and full testing.
Time and date incorrect.
Resets to 1/01/9? on power up.
Return to Ampcontrol for battery
replacement and full testing.
