GE DS3800NSFC Voltage monitoring module

The EPQ96-2 converts the relay output from a PI controller to a control voltage/current or PWM signal as input for the electronic speed governor. In case of supply voltage drop-out, the potentiometer is automatically preset according to the adjusted preset value or preset to the value before supply drop-out after reconnection of the supply voltage. The output is based on a 20 mA current generator shunted internally by means of a 500  resistor, resulting in the output signals shown below. The EPQ96-2 is equipped with two push-buttons on the front for settings between manual or auto mode

Manual control

The speed is controlled by activating two push-buttons on the front of the unit after the EPQ96-2 is set to manual mode.Output: To be set within the range: 0...±10V DC, 0…±20 mA DC. ±10V is set by means of a jumper mounted on the terminals. Start/end value: the start value and the end value can be adjusted inside the output span to any value between 20% span and up to 100% span by means of two potentiometers “min”, “max” located on the rear of the unit.
