Robertshaw Vibration Monitor 563A-C1, 24 Volts VDC Power Supply, NEMA 4 Housing

The Robertshaw Model 563A-C1 Vibraswitch Electronic Monitor is a microprocessor based supervisory control system designed for use with Robertshaw Model 365 or 366 Vibraswitch Malfunction Detectors. It may be used with one to eight Vibraswitches and has been programmed to provide a means of differentiating between valid excessive vibration and excessive vibration resulting from temporary external disturbances.

The Vibraswitch malfunction detectors 366 and 365A (not included) units provide maximum protection for large motors, pumps, compressors and other rotating or reciprocating equipment by responding to mechanical malfunctions the instant they occur.

The Start Time Delay circuitry inhibits monitoring from the time a machine is first started until it reaches its normal operation speed and condition. This time is adjustable from 0 to 999 seconds by means of three digital rotary switches. A Monitor Time Delay period is initiated when any Vibraswitch trips from excessive vibration. The Monitor Time Delay period is adjustable from 0 to 99 seconds by means of two digital rotary switches. If the vibration continues to the end of this period, the alarm and/or shutdown contracts will actuate and the red indicator within the Reset Button on the instrument door will turn ON. The Robertshaw 563AC1 monitor is NEMA 4 rated with a 24 VDC power Supply.
