DRMS Series Hybrid Motor Starters are intelligent and convenient solutions for controlling 3-phase asynchronous motors. These compact devices can provide up

to 6 functions in the same unit: Forward/Reverse, Soft Start/Soft Stop, Motor Overload Protection, and Mains Isolating Relay.

Motor overload detection is based on a thermal load curve. The relays are de-energized when an overload condition is present, ensuring a long service life.

INSTALLATION INSTRUCTIONS • Install the motor starter on the DIN rail, as shown on fig. 1. • Wire the motor starter to the control side. AWG #22 (0.5mm²) minimum, AWG #14 (2.5mm²) maximum. • Wire the motor starter to the output side. AWG #30 (0.05mm²) minimum, AWG #12 (4 mm²) maximum (stranded/solid). • Maximum terminal screw torque control side 3.46 lb-in (0.39 Nm) & output side 5-7 lb-in (0.564-0.79 Nm). • Use 60°C / 75°C copper conductors only.

FUNCTION DIAGRAMS tu = switchover delay time tp = overload response time according to characteristic class 10A or 5 DEVICE OPERATION Forward/Reverse Control Forward (clockwise) and reverse (anticlockwise) rotation can be selected via control inputs R and L respectively. The input signal detected first is executed if both inputs are applied simultaneously. After the detected signal is cancelled, the rotational direction is reversed via the Soft Start function.

Motor Overload Protection The thermal load of the motor is calculated using a thermal model (see Thermal Overload Protection Curves). The nominal motor current Ie can be adjusted via a potentiometer on the front. To calculate the thermal load the current is measured in phase T3. A symmetrical load current in all 3 phases of the motor is assumed for flawless operation. When the trigger value, stored in the trigger characteristics, is reached, the motor is switched off and the device switches to fault 8.
