Single phase motor
protection and suggested
wiring diagram
Single phase compressor motors are internally
protected by a temperature / current-sensing
bimetallic protector which senses the main and
start winding current as well as motor winding temperature. If the motor were to be overloaded
and the protector trips, it might take up to
several hours to reset and restart the compressor.
The trickle circuit provides the facility of heating
the compressor crankcase by feeding a small
current to the auxiliary winding and the run
capacitor (See the drawings in section “Electrical
connections and wiring”). For the larger single phase compressor models
NTZ048-068, the use of the PTC crankcase heater
is recommended.
PSC wiring may be used for refrigerant circuits
with capillary tubes or expansion valves with
bleed ports. Pressure equalisation must be ensured before start-up because of the low
starting torque characteristics of this system.
CSR wiring provides additional motor torque
at start-up, by the use of a start capacitor in
combination with the run capacitor. This system
can be used for refrigerant circuits with capillary
tubes or expansion valves. The start capacitor is
only connected during the starting operation, a
potential relay is used to disconnect it after the
start sequence. Some applications with high differential pressure
can require a very high starting torque. For such
cases the CSR starting kit can be converted to
a very high starting torque kit by an additional
start capcitor of 100 μF parallel to the start
capacitor of the CSR kit. This configuration
can also be used to reduce erratic starting
at unfavourable conditions such as very low
ambient temperature or weak voltage.
