If there is a TPR cable open circuit in your Pfeiffer Vacuum Controller, replace the cable.
Why is the Pirani pressure reading too high on my Pfeiffer Vacuum TPG 300?
A Pirani pressure reading that is too high on your Pfeiffer Vacuum Controller can be caused by a contaminated Pirani gauge. Try calibrating the measuring circuit or replacing the gauge. You may also want to clean the gauge.
What to do if the pressure display is unstable on my Pfeiffer Vacuum TPG 300 Controller?
If the pressure display on your Pfeiffer Vacuum Controller is unstable, the filter time constant might be too low. Increase the filtering to stabilize the display.
Why are the switching functions (relays) fluttering on my Pfeiffer Vacuum Controller?
If the switching functions (relays) on your Pfeiffer Vacuum Controller are fluttering, it could be due to hysteresis being too small. Try modifying the threshold values. Alternatively, increasing the filtering may resolve the issue.
What to do if the Pirani measurement circuit cannot be calibrated on my Pfeiffer Vacuum Controller?
If the Pirani measurement circuit on your Pfeiffer Vacuum Controller cannot be calibrated, the combination of the measurement plug-in board, gauge cable, and gauge might not be compatible. Select the correct combination. Another reason may be that the Pirani gauge is severely contaminated, in which case you should clean or replace the gauge.
Why does no display appear when my Pfeiffer Vacuum TPG 300 Controller is switched on?
If no display appears when your Pfeiffer Vacuum Controller is switched on, it might be because the unit was switched off for too short a period. After switching the unit off, wait approximately 10 seconds before restarting it.
What to do if a key is pushed on my Pfeiffer Vacuum TPG 300 Controller?
If a key is pushed on your Pfeiffer Vacuum Controller, release the key.
What to do if the TPR gauge is not connected to my Pfeiffer Vacuum Controller?
If the TPR gauge is not connected to your Pfeiffer Vacuum Controller, connect the gauge.
What to do if the TPR gauge is defective on my Pfeiffer Vacuum TPG 300?
If the TPR gauge on your Pfeiffer Vacuum Controller is defective, replace the gauge.
What to do if I get an incomprehensible reading on my Pfeiffer Vacuum TPG 300?
If you are getting an incomprehensible reading on your Pfeiffer Vacuum Controller, check if the plug-in board is securely screwed down and tighten the screws if necessary. Also, inspect the contacts for contamination or bending; clean or carefully straighten them.
