Product description
Structure / functions
The BCM 2000 is used solely for monitoring the operation of BOCK refrigerating compressors. All
monitoring parameters have been coordinated exactly to the compressor connected up in the factory.
Incoming signals are detected as status, information or error messages and processed to release,
shutdown and reporting functions. The unit does not exercise any regulating function.
The unit has three main components:
A - Electronic section B - Power supply section C - Control section
Altogether the unit has 8 monitoring functions: motor winding temperature, compressed gas tempera-
ture, oil temperature, oil pressure, liquid detection during start-up, compressor rotation detection,
surge guard, recommended oil change.
