What is Error 1226 on a Polar Cutter its a 2001 machine

Hi sir:

Cause:

This message occurs only in connection with a PDR board installed. The message
is output during a cut release, if the computer detects a difference between the
nominal and actual values of the clamping pressure. The nominal value results from
the machine parameter setting. The actual value of the current clamping process is
fed back to the computer via the board PDR for control purposes.
Attention! Please note: To carry out the tutorial during any service work performed,
the DIP switch on card CPxx for the service mode must have been previously
switched on, since the error control is suppressed in this way.
Remedy: - Check / replace PDR- board.

- Replace hydraulic control block.
- Check external switching of board PDR (S29).
- Short circuit +24V d.c.
- Check connection to ground

Blessing
