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.
6
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 IPC 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.
Check auxiliary contacts and wiring.
10
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.
6
Check continuity from the relay, through
the CCMC to power conductors. This can
be achieved by testing each phase to earth
at the outlet, provided the circuit is isolated.
Typical readings:
CCMC-415 2340k ohm
CCMC-1000 2340k ohm
CCMC-3.3k 7520k ohm
17
Relay Trips on MCF on
power up. Main contactor fail
condition. Check main contactor for leakage across
terminals on frozen contactor condition.
6
Flat or faulty battery. Return to Ampcontrol for battery
replacement and full testing.
11
Time and date incorrect.
Resets to 1/01/9? on power
up.
Low IS battery Return to Ampcontrol for battery
replacement and full testing.
