Heaters should be selected on the basis of the actual full load
current and service factor as shown on the motor nameplate or
in the manufacturer’s published literature. When the service factor
of the motor is 1.15 to 1.25, select heaters from the heater
application table. If the service factor of the motor is 1.0, or there
is no service factor shown, or a maximum of 115% protection is
desired, select one size smaller heater than indicated. When motor
and overload relay are in different ambients and when using non-
compensated overload relays, select heaters from the table using
adjusted motor currents as follows: decrease rated motor current
1 % for each °C motor ambient exceeds controller ambient.
Increase rated motor current 1% for each °C controller ambient
exceeds motor ambient.
COIL
The A200 motor controller is available with a single or dual
voltage coil. When equipped with a single voltage coil, the
contactor is wired as shown in Figure 6. A connection diagram
for a dual voltage coil is shown in Figure 4. When supplied with
a dual voltage coil, the motor controller is normally wired for the
high voltage connection. The wiring may be changed to the low
voltage connection by removing and reconnecting the jumpers as
illustrated below.
