Analysis Of The Displayed Values - Wow COOLIUS A50 Original Manual

6.1

Analysis of the displayed values

Pressure Transmitter:
With the correct calibration, dismount the LP quick coupler.
The ABS (Absolute) Pressure value compensated shall be roughly the ABS atmospheric pressure -10 / -15
mb.
Blow compressed air into the LP service hose (blue):
The display has to show an increase of the ABS Pressure value and of the ADC points.
Disconnect the Pressure Transmitter connector from the mainboard "A" (PWR).
The ABS Pressure value shall be 1 and the Pressure Transmitter ADC point should be roughly 1.
Refrigerant Scale:
The shown value is the net value (Total–Tare Weight Value)
The ADC point value is the total value.
The first four numbers shall be stable, the last three can float.
The values displayed are directly linked to the weight on the scale.
As a reference, consider that a calibrated scale with all the containers empty shall show roughly 8900000
points. Values that are significantly different from the reference indicate a possible problem.
To check quickly if the weighing system is working correctly it is enough to press on the load cell (scale
bracket): both the ADC points and the net value compensated shall increase.
Used Oil Scale:
The value shown is the net value (Total–Tare Weight Value)
The ADC point value is the total value.
The values displayed are directly linked to the weight on the scale.
CPU board temperature °C
The temperature is shown in tenths of Celsius degrees.
The displayed value is the temperature of a sensor mounted on the board.
