Soft Starter Voltage and Current Calibrations
Although not common, it is possible for a Soft Starter to show an incorrect Power Supply Voltage and/or Motor Current reading, in which case the reading can be calibrated by setting the following parameters:
For both the GW Series and GS Series Soft Starters:
- Current Calibration: Change parameter FM to increase or decrease the Soft Starter Current reading to align with the actual current drawn by the motor. If the Soft Starter Current reading is too high, reduce the value of this parameter. If the Soft Starter Current reading is too low, increase the value of this parameter.
- Voltage Calibration: Change parameter FN to increase or decrease the Soft Starter Voltage reading to align with the actual voltage of the power supply. If the Soft Starter Voltage reading is too high, reduce the value of this parameter. If the Soft Starter Voltage reading is too low, increase the value of this parameter.
* Please Note: The FM and FN parameters are most likely locked for editing, in order to remove the parameter locking, please set parameter FC = 2 first.
* Note that the GS Series Soft Starter also allows for calibrations using hardware (screw terminals) for making large adjustments – small screws on sides of Terminals (below plastic cover) – on the left-hand side for Current Calibration and on the right hand side for Voltage Calibration (turn Clockwise to reduce readings and Anti-Clockwise to increase readings).
