Hi,
i have the following problem: having the controller alone, no externals, no arm connected. When powering up the controller i dont have any power-led on the processor-board lighten up - so obviously the power-supply is not generating any supply-voltages.
is the a kind of "interlock" or loop which has to be closed or connected for the power-supply to start working? will this thing produce supply-voltages even outside the controller, on the desk for testing purpose? does anyone have a pinout for the power-supply or the backplane in the controller?
the 4 fuses inside the power-supply are ok.
there are 2 red LED's inside the power-supply-unit itself, labeled somewhat like AC H and AC L. one LED is just blinking when the AC is connected/switched on and lighten up when disconnecting the AC-power, dimming slowly thereafter - so it might be that these are some kind of Over-AC and Under-AC warnings.
does someone have a maintenance/service/circuit-manual of the c-series-controller, maybe the C70?
best regards
Carsten
