1.6. The PTC Starting Device
It should be noted that starting device 1 03N001 2, which is used for the freezing compressor of refrigerator/freezer uprights, is installed differently than is starting device 1 03N001 1, which is used for the refrigerating compressor.
On starting device 1 03N001 2, the N terminal is separated from the connections in the starting device and is used as a terminal for the thermostat wire to the refrigerating compressor.
Note that there are three black wires at this starting device, which can cause confusion in installation. The return wire from the freezing thermostat is normally equipped with a protective plastic cover. This wire is connected at terminal C on the starting device.
From serial No.212 starting device 1 03N001 1 or 1 03N0021 is mounted on both cooling and freezing compressors.
Universal PTC Starting Device
The relay 103N0015 is a universal relay, which can replace the relays 103N0002, 103N0005, 103N0011, 103N0012 and 103N0016.
103N0002 103N0005 103N0011 103N0012 103N0016
is replaced by
Place the shunt between M and N when replacing 103N0002, 103N0011 and 103N0016.
The plug S is only used when connecting a condenser.
The HST Starting Device
The tunction of the starting relay is to cut in the motor start winding in order to attain a torque. When the motor speed is high enough (and the current through the run winding is re- duced), the relay cuts out the start winding.
Ensure that the starting device and the starting condenser fit the compressor. See the spare parts list.
