Pump in alarm after 40 sec

Pump in alarm after 40 sec This weekend the pump was installed and it appears that after 40 seconds the pump goes into alarm? We have checked everything carefully, water supply OK, venting OK?

"Hi @patrickdl ,

I assume that it is a Marco UP12E, is this correct? According to p.12 of the user manual there are two warnings that use both LEDs. One says that:

Yellow and blue LED that blink together indicate that the power supply is providing the wrong voltage. Please check to have the correct wire section for the power supply and a charged battery, if present.

See table on p.13 regarding the wiring specifications If the wiring is not adequate there may not be the correct voltage at the pump terminals."
