The list of displays may be navigated from either direc-
tion by using the
(Up arrow) or
Down arrow
pads. For example, to change language from normal
view, press the
(Up arrow) pad once, press the
(Enter) pad to select your language, and press the
(Enter) pad again. The number of displays varies with
compressor model, but will follow this pattern.
The large Emergency Stop button located near the con-
troller overrides all electronic functions to turn off the con-
trol devices. The controller senses this, and will display
E-stop. To reset, twist and pull out the Emergency Stop
button, then press the
(Stop) pad to reset the WS
Controller.

LED lights
The four LED lights indicate the general condition of the
machine.
The blue Power indicator
simply indicates that power
is applied to the controller. It will blink very slowly if the
WS Controller is set up to automatically restart after
power failure.
The green Run mode indicator
indicates compressor
operation is enabled. It lights steadily if the motor is run-
ning. If the motor stops while in Automatic mode, this
LED will blink to indicate that the motor may restart.
The yellow Maintenance indicator
comes on when-
ever there is recommended maintenance or a warning.
The text display will periodically indicate the recom-
mended actions or the cause of the warning.
The red Fault indicator
indicates that a compressor
fault has occurred and needs to be repaired before fur-
ther operation. The text display will indicate the cause of
the fault.
The PC support program for the WS Controller provides
additional information about compressor operation and
advanced setup adjustments to optimize operation.
Software part numbers are shown in the display following
a power interruption or other interruption of communica-
tion with the controller. The P/N remains on the display
until satisfactory communications are established with
the Input/Output module.
