A controller for controlling a heater associated with the crankcase of a compressor senses electrical current flowing through the heater. The sensing is preferably accomplished by a transformer in combination with an amplifier providing a feedback signal to the controller. The transformer is installed in the line which carries the electrical current flowing through the heater. The controller checks for the presence of an appropriate voltage level from the amplifier. In the event that the voltage level is not above a threshold level, the controller sends an alarm signal indicating that the heater is not operating properly.

Crankcase heater control

Housing is provided for electronic circuitry that monitors the operation of a compressor. The housing includes a module containing the electrical circuitry as well as electrical connectors that connected the circuitry to external wiring. The module is mounted to an external housing member. The wiring inserts through an opening in the external housing member before being connect to the electrical connectors associated with the electronic module. Further openings in the housing member receive conduits carrying further wiring. The conduits extend outwardly from the housing member so as to allow the wiring in the conduits to be supported for an appreciable distance from the housing. A removable housing member is connected to the aforementioned housing member so as to cover the wiring connected to the electrical connectors associated with the electronic module. The removable housing member is easily removed from the aforementioned housing member so as to thereby allow access to the various connections of wiring to the electrical connectors associated with the electronic module.
