of
Operation
With the selector switch in the AUTO position the compressor will automatically start and stop
based on the signal from either the suction or discharge pressure switch. When shutdown by either
switch, the compressor will remain on standby until the pressure reverts back to the "cut in" point
of the switch, at which point the compressor will restart. If shutdown by high gas temperature, the
unit will remain off until the it cools down below the temperature switch set point and the fault is
cleared by pressing and releasing the emergency stop button. To manually stop the unit, switch the
HOA switch to the OFF position.
Electrical
Schematic
Description
The following explains the logic sequence as reflected on the schematic:
a.
With power applied to the unit and the selector switch (SA) in HAND, push
the START pushbutton.
b.
The two pressure switches, low inlet (SPI) and discharge (SPD) are connected
in series to the motor controller. If the inlet pressure is high enough to close
the inlet switch, and the discharge switch remains closed (pressure below the
switch "cut in" setting) the compressor will start.
c.
Current passes through the two closed pressure switches, the closed relay
(KA-2) and energizes the starter coil (KM). The starter coil starts the main
drive motor (M). The fan motor (FM) and hour meter (HM) also operate at
this point. The green light (HL1) will energize indicating the compressor is
running. Tripping of either the inlet or discharge switch will break current to
the coil which will stop the drive motor.
d.
If the 3
rd
stage temperature reaches the switch set point the temperature
switch (TIS) opens and de-energizes relay KA. When relay KA is de-energized,
contact KA-2 opens and removes power to the motor starter coil (C). This
stops the compressor motor, fan motor, and the hour meter. The green light
will de-energize. Contact K1-1 closes and the red light (HL2) energizes
signaling a high temperature condition. After the temperature switch has
reset, the emergency stop button must be pushed to clear the fault, followed
by the start button to restart the compressor in manual mode. In auto mode
the compressor will restart after the emergency stop is pressed and released.
e.
The compressor may also be run in the automatic mode by selecting AUTO on
the HOA (SA) switch. All features are the same as described above except that
after the inlet or discharge switch shut down the unit, the compressor will
automatically restart when the switches are moved to the "cut in" setting. The
compressor will continue cycling until the selector switch is moved to either
HAND or OFF.
f.
The unit may be stopped at any time by switching the HOA to OFF.
