19.3.2 Power Source Shuts Down
CONDITION POSSIBLE CAUSE, REMEDY
The power source shuts down when the EUT load is
applied If the companion power source shuts down when the
EUT load is applied, it is very likely that the power
source is being severely overloaded. Any severe
overload will cause the MX to fold back the output
voltage or trip off depending of the selected Current
protection mode.
The power source shuts down immediately when it is
programmed to the test voltage Another possible cause of shutdown is a short circuit
in the EUT wiring or EUT load. Make sure neutral and
line wires don’t form a short circuit.
19.3.3 Power Source Overload Light On
CONDITION POSSIBLE CAUSE, REMEDY
Overload light on power source is on When the overload light is on, the power source is close
to faulting or folding back the output voltage.
Adjust
EUT loading if possible to keep power source within its
ratings.
19.3.4 No Signal To PC Interface
CONDITION POSSIBLE CAUSE, REMEDY
EUT is being driven properly and voltage and current is
present, but the CTSMXL Software GUI shows zero
current or zero voltage or otherwise incorrect
measurement readings.. The PACS-3-75 front panel power switch is not on. Turn
on switch, check ON LED.
The ½ Amp input fuse is open. Replace fuse.
The interface cable between the PACS-3-75 and the PC
is not properly seated in its mating connectors. Reinsert
connectors. Check for any bent pins..
The Sensor Circuit board assembly inside the PACS-3-
75 module is defective. See next section.
