ACLD Troubleshooting using the ME-ARTR
This section assists you in using your router to identify a fault and to resolve an abnormal
operational condition detected within your ACLD system.
11.3.1 ACLD Fault Message Screens
When an ACLD fault is detected (i.e., ACLD’s LED blinks), navigate to the
METER: 06 ACLD
Meters/06A ACLD Status
menu to view the fault status. Figure 11-2 is an example of how ACLD
fault messages appear on the ME-ARTR router. Use the router’s LCD screen, your ACLD owner’s
manual, and the information in this section to identify and correct the issue.
11.3.2 Resolving
ACLD Faults using the ME-ARTR
For the listed faults below, refer to their respective remedy.
•
Desat Fault
– Hardware saturation has occurred—indicates a possible catastrophic failure.
Remedy:
This fault requires a reset of the ACLD. Press the ON/OFF switch on the side
of the ACLD controller to remove power to the unit, and then press the ON/OFF switch
again to restore power. If fault recurs, contact Sensata for service.
•
High Current Fault
– The current is at least 30% above rated current. This may be the result
of a load that is not sized correctly, or may be a bad power board.
Remedy:
Ensure that the load is connected. Press the ON/OFF switch on the side of the
ACLD controller to remove power to the unit, and then press the ON/OFF switch again
to restore power.
•
High VAC In Fault
– The AC input voltage is above 275 VAC.
Remedy:
This fault automatically clears once AC input voltage falls below 260 VAC.
•
No Load Fault
– No loads detected on either output terminals (or min. current
fl
ow to loads).
Remedy:
Check to ensure that the loads are sized and connected correctly.
•
Output Short Fault
– A shorted output to loads has been detected.
Remedy:
Check to ensure that the loads are sized and connected correctly. See the
ACLD owner’s manual for load sizing criteria.
•
Overcurrent Fault
– The current has reached an extremely high level (about twice the rated
current). Possibly the result of too big of a load.
Remedy:
Check to ensure that the loads are sized and connected correctly. Press the
ON/OFF switch on the side of the ACLD controller to remove power to the unit, and then
press the ON/OFF switch again to restore power. See the ACLD owner’s manual for load
sizing criteria.
•
Overtemp Fault
– The unit temperature has risen above 194°F/90°C—will automatically
reset once temperature falls below 158°F/70°C.
Remedy:
This fault automatically clears once the temperature falls below 158°F/70°C.
See the ACLD owner’s manual for load string criteria.
