SPECIFICATIONS (CONT.)
E-- AS THE UNIT STARTS DURING A CRANK CYCLE, AT A SET FLYWHEEL
SPEED AS SENSED BY A MAGNETIC SPEED PICKUP, CRANK DISCONNECT
OCCURS AND THE ASSC GOES TO THE RUN MODE. AT THIS TIME A
PROTECTION BYPASS TIME DELAY PERIOD BEGINS WHICH ALLOWS THE
ENGINE OIL PRESSURE TO RISE SUFFICIENTLY TO SATISFY THE
COMPRESSOR ENGINE PROTECTION CIRCUIT. THIS PREVENTS PREMATURE
SHUTDOWN. THE PROTECTION BYPASS TIMER SHOULD BE ADJUSTABLE
FROM 0 -- 60 SECONDS (FACTORY PRESET TO 15 SECONDS). THE
SPEED CRANK DISCONNECT ADJUST RANGE SHOULD BE FROM 20 -- 2000 HZ.
INSTRUCTIONS ON SETTING THIS SHOULD BE PROVIDED.
F-- ONCE THE ENGINE REACHES A NORMAL RUNNING CONDITION, THE UNIT
REQUIRES A WARMUP PERIOD PRIOR TO LOADING THE COMPRESSOR
TO ITS NORMAL OUTPUT PRESSURE. THIS WARMUP PERIOD SHOULD BE
ADJUSTABLE FROM 0 -- 10 MINUTES IN 10 SECOND INCREMENTS
(FACTORY PRESET TO 5 MINUTES).
G-- AFTER THE WARMUP PERIOD, THE ASSC WILL AUTOMATICALLY LOAD
THE COMPRESSOR BY DEACTIVATING THE START/RUN VALVE. THIS
ENABLES THE COMPRESSOR TO DELIVER RATED PRESSURE AND FLOW
FOR NORMAL OPERATION.
H-- THE UNIT MAY BE SHUT OFF AT ANY TIME WHILE RUNNING IN
AUTOMATIC MODE BY EITHER SWITCHING THE ASC TO ”OFF”
OR TURNING THE COMPRESSOR ON/OFF SWITCH TO ”OFF ON
THE FRONT OPERATOR PANEL. THIS WILL SHUT DOWN THE
COMPRESSOR IMMEDIATELY.
J-- ONCE THE CUSTOMER TRANSFER SWITCH OPENS, THE UNIT WILL BEGIN
A COOL--DOWN PERIOD. THE COOL--DOWN PERIOD SHOULD BE ADJUSTABLE
FROM 0 -- 30 MINUTES (FACTORY PRESET TO 5 MINUTES).
K-- AT THE END OF THE COOL--DOWN PERIOD THE UNIT WILL AUTOMATICALLY
SHUT DOWN AND RETURN TO THE STANDBY MODE AS IN 4.4 A.
5. OPERATION SEQUENCE -- MANUAL MODE
WHEN THE SELECTOR SWITCH INSIDE THE ASSC BOX IS TURNED TO THE ”MANUAL”
POSITION ALL AUTOMATIC FUNCTIONS WILL BE DISABLED. THE COMPRESSOR
MUST BE ABLE TO BE OPERATED MANUALLY FROM THE COMPRESSORS MAIN
CONTROL PANEL. THE COMPRESSOR MUST SHUT DOWN IMMEDIATELY IF, WHILE
COMPRESSOR IS RUNNING IN AUTOMATIC MODE, THE SELECTOR SWITCH IS
SWITCHED TO MANUAL OR OFF. IF THE ON/OFF SWITCH ON THE COMPRESSORS
MAIN CONTROL PANEL IS TURNED ”OFF” THE UNIT WILL IMMEDIATELY SHUT DOWN.
6. OPERATION SEQUENCE -- OFF MODE
WHEN THE SELECTOR SWITCH INSIDE THE ASSC BOX IS TURNED TO THE ”OFF”
POSITION DURING ANY MODE OF OPERATION, THE UNIT WILL IMMEDIATELY SHUT
DOWN. IF THE SWITCH ON THE COMPRESSORS MAIN CONTROL PANEL IS TURNED
”OFF”, THE UNIT WILL ALSO IMMEDIATELY SHUT DOWN.
