If anyone on the forum has a Heidenhain Positip 850 I have a favour to ask.
My unit has died and it appears the power supply is at fault. If someone has a similar unit I would be very grateful if they could take the lid off and measure the DC voltages out of the power supply. My plan is to replace the existing with other power supplies, there's plenty of space within to do so.
There are four wires on the output connector, brown, red, black and yellow. As they are laid out it may be black is the common 0V and the other colour wires are the positive outputs, or they are in pairs.
It's really easy to get the lid off, it's seven screws as shown below and the lid slides back and off.
Even though I have a later unit I like this old CRT type because the display is large and bright.
In the meantime I will ask Heidenhain if they can supply a wiring diagram so I can get the power supply repaired, but I am not holding too much faith in them doing so.
Many thanks Adrian.
