Hardware problem with the power supply
After the electronics supply has been switched on, both LEDs
flash
, and
no
actual-value display is provided. Take off the control panel and
observe the 7-segment display. When all 7 segments light up, this means
there is a problem in the electronics supply. Replace SDCS-PIN-3A if
necessary.
