Bell & Gossett P2001489 Integrated Technologic with Sensorless Control - Manual (Page 51)

Warning/Alarm Description Cause Remedy
59 — Current limit The current is higher than
the value in 4–18 Current
Limit.
Ensure that motor data in
parameters 1–20 through
1–25 are set correctly.
Possibly increase the
current limit. Be sure that
the system can operate
safely at a higher limit.
60 — External interlock A digital input signal is
indicating a fault condition
external to the frequency
controller.
62 — Output frequency at
maximum limit
The output frequency has
reached the value set in 4–
19 Max Output Frequency.
Check the application to
determine the cause.
Possibly increase the output
frequency. Be sure the
system can operate safely at
a higher output frequency.
The warning will clear wieh
the output drops below the
maximum limit.
65 — Control card over
temperature
The cut-out temperature of
the control card is 80°C.
Check that the ambient
operating temperature is
within limits.
Check for clogged filters.
Check fan operation.
Check the control card.
66 — Heatsink temperature
low
The frequency converter is
too cold to operate. This
warning is based on the
temperature sensor in the
IGBT module.
Increase the ambient
temperature of the unit.
A trickle amount of current
can be supplied to the
frequency controller
whenever the motor is
stopped by setting 2–00 DC
Hold/Preheat Current at 5%
and 1–80 Function at Stop.
67 — Option module
configuration has changed
One or more options have
either been added or
removed since the last
power down.
Check that the
configuration change is
intentional and reset the
frequency controller.
68 — Safe stop activated Loss of the 24 VDC signal
on terminal 37 has caused
the frequency controller to
trip.
To resume normal
operation, apply 24 VDC to
terminal 37 and reset the
frequency controller.
69 — Power card
temperature
The temperature sensor on
the power card is either too
hot or too cold.
Check that the ambient
operating temperature is
within limits.
Check for clogged filters.
Check fan operation.
Check the power card.
70 — Illegal FC
configuration
The control card and power
card are incompatible.
