Low VA
The ACE2 is not correctly calibrated.
The regulator has a bad field circuit or has
become shorted.
Run though the Lamps-Out Calibration;
during that process the ACE2 calibrates the
system.
Recalculated the present load, and adjust
accordingly.
Incorrect Current
(Incorrect Current)
ACE2 configuration does not match
regulator.
The ACE2 is not properly reading the steps
of the regulator. (In Stand-Alone Only)
The regulator is not outputting the correct
current levels.
Make sure that the ACE2 is configured for 3
Step or 5
Step
depending on the regulator.
Ensure the regulator is set to 6.6A or 20A
depending on the regulator type.
In the lower left corner of the LCD screen,
the step of the regulator is displayed, if this
does not match the actual step, there is a
problem with the internal wiring. See wiring
diagrams.
There is an internal problem in the regulator;
call ADB Airfield Solutions for further
assistance. Return CCR to RMT control.
Protective Shutdown
CHECK THE CALLOUT
(Protective Shutdown)
The regulator had an error such as Open
Circuit or Low VA and was shut down. The
regulator was commanded On but has no
output current.
Check the Regulator for open connections
and visible damage. Restart the system.
Over Current
The regulator’s output has gone above the
acceptable threshold.
The ACE2 is set to the incorrect regulator
values.
Open Circuit problems, or the SCR has
become damaged. Check the SCR and all
connections.
Check to ensure the ACE2 is set for the
current regulator. If the regulator is a 20A
output, ensure ACE2 is set to 20A. If the
regulator is a 6.6A output ensure ACE2 is
set to 6.6A.
Open Circuit
The regulator does not have a connection
to the load. Or the field circuit is open.
Remove main power. CAREFULLY Check
all connections in field circuit.
Lamps-Out Warn
(Lamps-Out Warning)
Too many lamps have gone out passing
the set threshold.
The Lamps-out warning threshold is too
low.
Replace burned-out lamps.
Reset the Lamps-out threshold using the
display in standalone. (Figure 8) Or use
ACLMS configuration.
Lamps Out Alarm
Too many lamps have gone out passing
the set threshold.
The Lamps out Alarm threshold is too low.
Replace burned-out lamps.
Reset the Lamps-out threshold using the
display in stand-alone. (refer to Figure 8) Or
use ACLMS configuration.
Insulation Warn
(Insulation Warning)
Somewhere on the load a wire has become
exposed, allowing current to flow to
ground.
The Insulation Alarm threshold is too low.
Check load for damaged lines.
Reset the Insulation threshold using the
display in standalone. (Figure 8) or use
ACLMS configuration.
