2005 Heidelberg PM 74

Hello all.
Fault with PM 74 registration.
Mechanically it is registering 100% but it still continues to beep.
This happens no matter what side you register.
Checked sensors both sides (clean etc) and all seems fine.
What are the likely causes of this?
Help appreciated
Thank you

Hi sir
How did you check the sensors? Did you follow the leaf presence signal? Sometimes the sensor glass breaks and disrupts the reading range. You need to make sure the sensors and the control box are in good condition. To do this, try with another sensor.
Good luck

Where is the control box for the sensors?

follow cable you will find it under the margin table

It is just a 3 plug connector.
I am thinking that because it's continues to beep no matter what side I Register that the problem is the sensor in the middle.Could this be the case?
Thankd
