UNLOAD (REMOTE) BUTTON
The administrator may set up the controller for
remote control by Modbus. To do so, select the
“Modbus timer 1” to control the “Remote Unload”
function above. Also select “Remote”, Hours”, or
“ComNum” Sequence mode on the User’s
“Adjustments” tab to enable remote control.
When this is done, an additional button labeled
“Unload” will appear under the “Connection” button in
the Status Bar. See Figure 7-12. Click on the
“Unload” button to toggle the compressor operation.
A bright yellow box next to the Unload button
indicates that the machine is being forced to unload.
A darkened yellow box next to the button indicates
that the machine will operate normally.
If continuous communication from the PC is not
received, the compressor will revert to normal
operation within a couple minutes.
SENSOR CALIBRATION
The compressor is equipped with sensors that
monitor and measure various characteristics of the
compressor performance. These values are received
at the WS Controller as analog input signals from the
sensor. Most sensors input can be adjusted to
calibrate the reading at the controller with the actual
measured value at the sensor location. This section
will describe the steps necessary to calibrate the Line
Pressure transducer. Calibrate other sensors in the
system in a similar manner.
