The Robertshaw 375A-A3-F3 Vibraswitch malfunction detectors provide maximum protection for large motors, pumps, compressors and other rotating or reciprocating equipment by responding to mechanical malfunctions the instant they occur. Robertshaw "Start Delay" FUNCTION holds the Vibraswitch armature in its "reset" position for a preset starting time after application of supply voltage to the instrument. This prevents the Vibraswitch from tripping out during machine startup. Fixed timing periods of 15, 30, 60 or 90 seconds are available. After the time period, the Vibraswitch functions as normal with shutdown or alarm functions provided by utilizing the SPDT switch contacts in the unit. In addition the Robertshaw "Monitor Delay" function prevents nuisance shutdowns due to tripping-out of the Vibraswitch during high level short term transient vibration conditions by automatically resetting the Vibraswitch. Under continuing high vibration, the Vibraswitch trips, is immediately reset, trips out again and is reset; this �sampling� process continuing until the time delay period has elapsed, after which the unit remains "tripped" out. An AC output by means of a solid state "TRIAC" switch can be used for either ALARM or SHUTDOWN. The "TRIAC" switch can be set for either NO or NC operation by repositioning the jumper plug located on the circuit board.
The Robertshaw 375AA3F3 vibration switch has a range of 0-4.5 G's. Contacts are SPDT 5A for the Start Delay models and SPST 2 A Triac Solid State Contacts (NO or NC operation) for the Monitor or Start & Monitor Delay Models. The Robertshaw 375AA3F3 is NEMA 4, NEMA 12 and CSA enclosure 4 and 12.
