What to do if there is no change in recovery volume in Protec Protection Device?
If the Protec Protection Device displays no change in recovery volume, first stop recovery. Then, check if the support screw of the gas cylinder load cell is loosened according to the 'Operation preparations' chapter. Finally, calibrate or change the gas cylinder load cell, or replace the PCA.
Why does the recovery function not stop on my Protec AC-200-dual?
If the Protec Protection Device recovery function does not stop, it could be due to a leakage in the automotive A/C or equipment pipeline. Perform a leakage test, referring to the service manual for the machine leakage test. Alternatively, the compressor may not be working, in which case it should be replaced. A faulty pressure sensor can also cause this issue; try fastening the pressure sensor connection to the PCA or replacing the pressure sensor.
Why is my Protec AC-200-dual Protection Device charging slowly?
If the Protec Protection Device is not charging or is charging slowly, it could be due to insufficient refrigerant in the equipment. In this case, fill the equipment tank with more refrigerant. Another potential cause is a problem with the charge line. Inspect the charge line, including the tank red valve, tank red hose, solenoid #5, solenoid #9 (high side), solenoid #11 (long side), service hoses, and HP/LP quick couplers.
What to do if Protec AC-200-dual Protection Device displays high pressure alarm 004?
If the Protec Protection Device shows 'High pressure alarm 004' but the gas cylinder gauge does not indicate excessive pressure, first check if the high pressure switch plug is disconnected from the PCA socket and fasten it. If the issue persists, inspect the hoses and connections between the compressor exit and the tank blue hand valve for any blockages.
How to fix no display on Protec Protection Device?
If your Protec Protection Device has no display, the fuse may be fused in the power cable connection box or PCA; try changing the fuses. The PCA might be burnt, requiring a PCA replacement. A loosened power cable could also be the cause, so ensure it's reliably connected. Lastly, the LCD may not be working, in which case, replace the LCD.
Why is the vacuum pump injecting oil in my Protec AC-200-dual Protection Device?
If the vacuum pump of the Protec Protection Device is injecting oil, it may be due to an excessive oil volume. Discharge some oil to the proper level. Alternatively, the entrance pressure could be too high; try running the Recovery function first.
How to fix low vacuum degree in Protec AC-200-dual?
To address a low vacuum degree in the Protec Protection Device, start by adding oil to the central line if the vacuum pump oil is insufficient. If the pump oil is emulsified or dirty, replace it with new oil. Also, check for a plugged pump oil inlet and clean it if necessary. Examine the pump connection for any leakage and ensure the connection is secure. Lastly, maintain the machine, paying special attention to o-rings, washers, and other sealing parts that may be worn out.
What does alarm 005 mean on Protec AC-200-dual Protection Device?
If the Protec Protection Device displays alarm 005 while the auto A/C has refrigerant, it indicates that the low pressure switch plug is disconnected from the PCA socket. Fasten the low pressure switch plug to resolve this issue.
What to do if vacuum pump is pressurized during recovery of Protec Protection Device?
If, during recovery, the vacuum pump in your Protec Protection Device is pressurized and there's too much oil in it after a period, it suggests that the contact between solenoid valve #8 and the valve base is not well sealed. To resolve this, remove solenoid #8 from the valve base and clean both the solenoid valve and the valve base.
Why is there suction in the old oil bottle during vacuum in Protec AC-200-dual?
If there is suction in the old oil bottle during vacuum in your Protec Protection Device, the contact between solenoid valve #2 and the valve base is likely not well sealed. Remove solenoid #2 from the valve base and clean both the solenoid valve and the valve base.
