WS CONTROLLER FAULTS AND WARNINGS
5.4
MACHINE BEHAVIOR AFTER
A POWER INTERRUPTION
If the compressor was faulted prior to the power
interruption, the controller will resume the FAULTED
condition and display the reason for the fault. Repair
the cause of the fault and press the STOP
pad to reset the controller.
If the compressor was manually stopped prior to the
power interruption, the controller will return to the
manually stopped mode. Press the start button to
manually restart operation.
If the restart timer is greater than zero AND the
controller was in Automatic or Manual mode prior to
the interruption, the controller will resume that mode
after the restart timer expires. No key press is
necessary to restart the compressor.
5.5
INTERNAL BATTERY
The WS Controller employs an internal battery that
maintains the real-time clock and maintains the
integrity of the controller memory records when
power is disconnected from the controller. For best
performance, ensure that the battery is functioning.
If the controller is operated with a drained or dead
battery, the time-of-day records will not work properly
and loss of recent records could occur. If recent
records are lost due to an inoperative battery (or
other reason), the controller will revert to the last
saved versions of settings and records.
The internal battery is located inside the controller I/
O module and will operate for several years without
requiring maintenance. When the battery voltage
gets low, the controller will issue a “Replace Battery”
warning. Perform the following steps to replace the
battery.
