5.4.2 PULSAR Motor

Connect the pump motor to the J3 terminal block labeled 'PUMP MOTOR OUT AC/DC.' (Use 14

AWG (2.1mm

), 105

C insulation wire size or larger.) The pump motor must be wired to operate at

the DLC supply voltage (i.e., if the power supplied to J1 is 115VAC 60Hz, then the motor must operate

on 115VAC at 60Hz).

THE DLC USES SOLID-STATE RELAYS FOR IT'S HIGH VOLTAGE OUTPUTS (I.E., MOTOR AND

ALARM). IN THE 'OFF' STATE, THESE DEVICES TYPICALLY LEAK 20-30MA OF CURRENT AT THE

SUPPLY VOLTAGE TO THE ATTACHED DEVICE (OR TERMINAL BLOCK)! THE SUPPLY POWER

MUST BE DISCONNECTED AT THE MAIN BEFORE WORKING ON ELECTRICAL CONNECTIONS OR

ANY MOVING PUMP COMPONENTS (E.G., MOTOR, GEAR TRAIN, ETC.).

DOUBLE CHECK ALL CONNECTIONS TO CONFIRM GOOD ELECTRICAL CONTACT BETWEEN THE

TERMINAL BLOCK CLAMP AND BARE WIRE. MAKE SURE THE CLAMP IS ON THE WIRE, NOT THE

INSULATION. INSURE THAT BARE WIRE IS NOT FRAYED AND DOES NOT RISE ABOVE DIVIDERS.

If the PULSAR pump motor is controlled by a Variable Speed Drive (e.g., DC Drive), the Variable

Speed Drive must be powered by the DLC. Wire the Variable Speed Drive to J3. Wire the PULSAR

motor to the Variable Speed Drive in accordance with the Variable Speed Drive manufacturer's

instructions. Refer to Section 8 – Diagrams: Diagram 2 for recommended wiring.

If the PULSAR pump motor or Variable Speed Drive operates at a voltage different than that supplied

to the DLC or is a three-phase motor, then a motor starter must be used. Wire the motor starter relay to

J3. Wire the PULSAR motor or Variable Speed Drive to the motor starter in accordance with the

starter manufacturer's instructions. Refer to Section 8 – Diagrams: Diagram 2 for recommended

wiring.

DAMAGE MAY OCCUR TO THE DLC IF THE PULSAR PUMP MOTOR IS NOT WIRED AND

COMMUNICATING WITH THE DLC.
