Motor current fell below the value set in DRY WELL
CURRENT under OPERATING PARAMETERS menu.
Used to detect dry well condition.
Indicates a large and sudden overcurrent event on the
output module. Check the motor circuit for faults. Sudden
changes in the load may also have occurred such as the
closing of a relay that results in an across-the-line start of a
motor. Never install relays in the motor circuit.
Input voltage has fallen below a level for safe operation of
the drive.
A fault between an output line and earth has been
detected. Immediately disconnect input power and check
output lines with a megger to verify a fault. Nuisance trip is
a possibility. Sensitivity of fault detection can be adjusted
by the Operating Parameter GND FAULT DETECT. See
Table 12 for details.
Indicates open circuit. 4-20mA analog signal is not present
on Control Terminals I+ and I-. This could indicate failure
of the 4-20mA sensor or that the cables from the sensors
have been disconnected. Only in Analog CP.
Indicates closed circuit. Check for short circuit between
lines. Check the polarity of the wires on I+ and I- . Only in
Analog CP.
Broken Pipe fault. Indicates the possibility of a broken
pipe.
P = Fault may be related to an adjustable parameter. Always check the value of the
parameter to eliminate nuisance tripping.
1 = Drive has shut down due to a potentially dangerous condition. Drive will remain OFF
until input power is cycled OFF/ON. Use caution if the drive is restarted.
2 = WARNING: Auto restart allowed for this fault. Motor may restart automatically
without warning after a fault when operating conditions permit. Make certain input power is
disconnected before servicing the unit or its connected loads.
