DIGITAL INPUT OPTIONS (DROP-DOWN
ARROWS)
The following options may be selected for a Digital
Input by clicking on the associated drop-down arrow
(refer to Figure 7-10):
ON—Activates the function continuously. The input
signal is ON.
Off—Deactivates the function. The input signal is
OFF.
Running—Activates the function when the
Compressor is running.
Din 7, 8, 9, 4 ON—Activates the function when the
input signal at the respective input (7, 8, 9, or 4) is
ON. The list of available inputs varies with models.
Din 7, 8, 9, 4 OFF—Activates the function when the
input signal at the respective input (7, 8, 9, or 4) is
OFF. The list of available inputs varies with models.
MB Remote ON—Activates the function when the
Modbus Remote signal is ON.
MB Timer 1, 2, 3 ON—Activates the function when
the respective Modbus Timer signal (1, 2, 3) is ON.
MB Remote OFF—Activates the function when the
Modbus Remote signal is OFF.
MB Timer 1, 2, 3 OFF—Activates the function when
the respective Modbus Timer signal (1, 2, 3) is ON.
FACTORY-DEFINED OUTPUT OPTIONS (DROP-
DOWN ARROWS)
The following options may be selected for a Factory
Defined Relay (A – E) by clicking on the associated
drop-down arrow (refer to Figure 7-10):
ON—Turns the relay ON.
OFF—Turns the relay OFF.
Drain—Activates the relay when the Drain solenoid
is actuated.
Running—Activates the relay when the compressor
is Running.
Enabled—Activates the relay when the compressor
is Enabled.
Fault—Activates the relay when a Fault condition
occurs.
Warning—Activates the relay when a Warning
condition occurs.
Fault or Warn—Activates the relay when either a
Fault or a Warning occurs.
Master Enabled—Activates the relay when the
controller is enabled as the Master device in a
sequence.
Dryer Running—Activates the relay to operate an
integrated refrigerated dryer.
ANALOG SIGNAL ZERO TRIMS
The Analog Zero Trim settings allow for calibration of
various analog inputs. Refer to Figure 7-10. Analog
inputs are assigned to sensors used to measure
specific characteristics of the compressor system.
The Analog Signal Zero Trims function is used to
adjust the displayed value of the measurements to
equal the measured value at the analog device.
Sensor Calibration on page 63 provides steps on
calibrating analog input measurements.
The inputs used vary with compressor models and
design. The display will indicate which sensors are
active by indicating their function.
Typical analog input assignments are shown below.
