5.4.2 PULSAR Motor
In most cases the DLCM is supplied with a factory installed DC motor. If a motor was not supplied, it
is important to select the proper type. Refer to the chart below for acceptable DLCM motors (refer to
Section 9 – Specifications for motor details):
Motors must be permanent magnet, SCR drive rated DC motors. The DLCM cannot control motors
with separate field windings.

Connect the permanent magnet DC pump motor to the J3 terminal block labeled 'PUMP MOTOR OUT
AC/DC.' Use 14 AWG, 105
° C insulation wire size or larger. If the DLCM supply voltage is
115VAC, you must use a 90Volt Armature motor. If the DLCM supply voltage is 230VAC, you must
use a 180Volt Armature motor.

At high motor turndown settings the DC motor can overheat under certain conditions. Non-standard
motors must include built-in thermal protection and a dry contact thermal switch for connection to the
DLCM’s Motor Thermostat input. Refer to Section 5.8 – Motor Thermostat for additional
information.
