Digistart D3: User Guide
Issue: G
8.8.9 Group 8 - Analog I/O
The Digistart D3 has one analog output (terminals AO1, 0V).
If required, a second analog output and an analog input are available on the input/output expansion card.
8A – Analog Input Trip
An analog input can be fitted to the Digistart D3 if required. An external device can activate the analog input to trip the
soft starter in response to external conditions.
Options:
Do Not Trip (default)
Trip High
Trip Low
Description:
Selects the soft starter's response to the analog input signal.
8B – Analog Input Scale
Options:
0-10 V
2-10 V (default)
Description:
Selects the scale of the analog input.
8C – Analog Trip Point
Range:
0% - 100%
Default:
50%
Description:
Sets the signal level at which an analog input trip will occur, as a percentage of the maximum
signal on the input.
NOTE
The analog input is only available if the input/output expansion card is installed.
8D – 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.
8E – Analog A Scale
Range:
0-20 mA
4-20 mA (default)
Description:
Selects the range of the analog output.
8F – 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.
8G – 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.
