• 8 Analog Output
The LV-DS has an analog output, which can be connected to associated equipment to monitor motor
performance.
8A – Analog Output A
Options:
Current (% FLC) (default)
Current as a percentage of motor full load current.
Motor Temp (%)
Motor temperature as a percentage of the motor's
thermal capacity.
Motor kW (%)
Measured motor kilowatts, as a percentage of
maximum kW.
Motor kVA (%)
Measured motor kilovolt amperes, as a percentage of
maximum kVA.
Motor pf
Motor power factor, measured by the soft starter.
Measured motor kW:
√3 x average current x mains reference voltage x
measured power factor
Maximum motor kW:
√3 x motor FLC x mains reference voltage. Power
factor is assumed to be 1
Measured motor kVA:
√3 x average current x mains reference voltage
Maximum motor kVA:
√3 x motor FLC x mains reference voltage
Description: Selects which information will be reported via the analog output.
8B – Analog A Scale
Range: 0-20 mA
4-20 mA (default)
Description: Selects the range of the analog output.
8C – Analog A Maximum
Range: 0% - 600% Default: 100%
Description: Calibrates the upper limit of the analog output to match the signal measured on an
external current measuring device.
8D – Analog A Minimum
Range: 0% - 600% Default: 0%
Description: Calibrates the lower limit of the analog output to match the signal measured on an
external current measuring device.
• 9 Auto-Reset
The LV-DS can be programmed to automatically reset certain trips, which can help minimise operating
downtime. Trips are divided into three categories for auto-reset, depending on the risk to the soft starter:
Group
A
Current imbalance
Phase Loss
Power loss / Power circuit
Frequency
B
Undercurrent
Instantaneous overcurrent
Input A Trip
C
Motor overload (thermal model)
Motor thermistor
Heatsink Overtemperature
Other trips cannot be automatically reset.
This function is ideal for remote installations using 2-wire control in Remote mode. If the 2-wire start signal is
present after an auto-reset, the LV-DS will restart.
9A – Auto-Reset Action
Options: Do Not Auto-Reset (default)
Reset Group A
Reset Group A & B
Reset Group A, B & C
Description: Selects which trips can be auto-reset.
9B – Maximum Resets
Range: 1 - 5 Default: 1
Description: Sets how many times the soft starter will auto-reset, if it continues to trip. The reset
counter increases by one each time the soft starter auto-resets, and decreases by
one after each successful start/stop cycle.
