Restore Backup Restores all the user programs (settings) to the status before
last change was done. This function can be used to restore
programs which have been deleted or modified by mistake.
Close Exits the Calibration tool service program.
Before performing the following calibrations, start the System Calibration
Software and activate “Calibration” in the “Mode” frame.
6.4.2 EXTERNAL PRESSURE SENSOR AND MAIN PRESSURE
REGULATOR CALIBRATION
This also calibrates the “Low pressure” alarm
1. Do not connect the equipment to the external air supply, remove the
red cap from the Main Pressure connector (Fig.4, ref.6).
2. Adjust R47 on the 393120 sensor board (decreases clockwise) until you
read 0mBar in the “External” indicator of the “Pressure” frame.
Connect a 10bar (145PSI) pressure gauge to the Main Pressure
connector, connect air supply to the equipment, loose the Phillips screw
on the Main Pressure Regulator (Fig.4, ref.8) and rotate the knob to
read any pressure between 4.5 and 5Bar on the pressure gauge.
3. Adjust R45 on the 393120 until the reading in the “External” indicator of
the “Pressure” frame matches (within display resolution) the pressure
gauge reading.
4.
Rotate the main pressure regulator knob fully counterclockwise and
then slowly adjust for a reading of 5.2 -0+0.1Bar.
Note: for this calibration, the external pressure source should be at 6±
±±
±
0.1Bar.
The pressure regulator has a noticeable hysteresis, after each
adjustment of the knob position, activate air flow.
At the end of this calibration, tighten the screw to stop the regulator knob,
remove the pressure gauge from the Min pressure connector and re-plug the
red cap.
