6.5.3 Compressor High Temperature
See Figure 6-11. The compressor high temperature switch is mounted on the high pressure compressor
block, on the third, fourth or fifth stage head, depending on model. Under normal operating conditions,
the switch is closed. On a high temperature condition, the compressor will shutdown and the alarm will
be displayed on the Operator Interface.
6.5.4 Compressor Low Oil Pressure
See Figure 6-12. The compressor Oil Pressure Sensor is located on the back of the compressor block,
mounted with the oil pressure gauge. During start-up of the compressor, the oil pressure sensor is
bypassed for a time period set in the program by
OIL PRESS TD
parameter. This allows the oil pres-
sure to stabilize at operating pressure before the an alarm is sensed. After this initial time period, should
the compressor lose oil pressure, the Oil Pressure Sensor will cause the alarm to be displayed on the
Operator Interface.
6.5.5 Compressor Overrun Timer
The compressor has an timer, where if the compressor runs continuously for a number of hours set by
the
OVERRUNTIMER
parameter, the compressor will shutdown, and the alarm will be displayed on
the Operator Interface. This is done to secure the equipment if it were to be started and left unattended.
6.5.6 Condensate Fault
See Figure 6-13. The compressor condensate level switch is located in the condensate collection tank,
below the Automatic Condensate Drain separator. The switch is N.O., Normally Open, and is con-
nected to the PLC. Refer to wiring diagram for additional information. As the condensate tank fills up
the Condensate Level Float Switch rises until it closes. At this time the compressor will shutdown and
NOTICE
If the DIN Connector is removed, ensure that it is replaced in exactly the same position, otherwise electri-
cal damage to the unit may occur.
