An overvoltage suppressor (or surge suppressor) is an appliance designed to protect electrical devices from voltage spikes. A surge suppressor attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold.

These surge suppressors are built in to the latest Pacemaker models and machine controls (from 2009).

Check, if one or more modules of the surge suppressors are red/defect. Replace the red modules.

Attention!!!

Do not bridge the signalling contacts and run the machine with defective red modules because they no longer protect the system from voltage peaks!!!
If the modules are defective, check the main supply. Measure and check all voltages between the phases and all phases to earth before exchange the modules and restart the machine.

Software Upgrade:

The software for the Pacemaker HF is memorized on a small processor board. For an update with new software, you need to change this board.
NOTE:

Before you start to change the board write down the voltage value you were using for your application.

 

Switch off the main switch of PowerCURE™

 

WARNING:
Wait 5 minutes, before you remove the cover. Capacitors with high voltage inside!

 

Remove the processor board carefully by hand. Do not use any tools for that.

 

Install the new processor board.

 

NOTE:
Be careful and make sure that you mount the new processor board correctly and that pins match the socket!! Watch from the side.

 

NOTE:
When you first start up, use a low voltage of approx. 80 V.
We hope the upgrade work was successful. Thank for your support!
