Programmable Parameters
8G –
Low Current Flag
The soft starter has low and high current flags to give early warning of abnormal operation.
The current flags can be configured to indicate an abnormal current level during operation,
between the normal operating level and the undercurrent or instantaneous overcurrent trip
levels. The flags can signal the situation to external equipment via one of the
programmable outputs.
The flags clear when the current returns within the normal operating range by 10% of the
programmed flag value.
Range:
1% - 100% FLC
Default:
50%
Description:
Sets the level at which the low current flag operates, as a percentage of
motor full load current.
8H –
High Current Flag
Range:
50% - 600% FLC
Default:
100%
Description:
Sets the level at which the high current flag operates, as a percentage of
motor full load current.
8I –
Motor Temperature Flag
The soft starter has a motor temperature flag to give early warning of abnormal operation.
The flag can indicate that the motor is operating above its normal operating temperature but
lower than the overload limit. The flag can signal the situation to external equipment via one
of the programmable outputs.
Range:
0% - 160%
Default:
80%
Description:
Sets the level at which the motor temperature flag operates, as a
percentage of the motor's thermal capacity.
8J –
Main Contactor Time
Range:
100 – 2000 milliseconds
Default:
400 milliseconds
Description:
Sets the delay period between the starter switching the main contactor
output (terminals 33, 34) and beginning the pre-start checks (before a start)
or entering the not ready state (after a stop). Set according to the
specifications of the main contactor used.
9.11 9 Analog Output
9A –
Analog Output A
Options:
Current (% FLC)
(default)
Current as a percentage of motor full load current.
Motor Temperature
(%)
The motor's temperature, calculated by the thermal
model.
Motor pf
Motor power factor, measured by the soft starter.
Heatsink
Temperature %
The soft starter's temperature, as a percentage of the
heatsink’s maximum allowed operating temperature.
Description:
Selects which information will be reported via the analog output.
9B –
Analog A Scale
Range:
0-20 mA
4-20 mA (default)
Description:
Selects the range of the analog output.
