6105 power supply shutting down

[Rosscopeco]

Hi Roger,
One of my 6105s keeps shutting down. The red light goes out after a while and the pump stops. If I unplug the power supply and plug it back in it works fine.
The problem started when I altered the program so that the pump is stopping and starting. In the previous pulse setting the pump was always on and had no issues.
The pump seems pretty clean and the power supply has the 18v jumper installed.
Should I be looking at the power supply or the pump? or both?
:beer:
Ross.

This would generally be an overload, the pump is drawing more than the 50W limit of the power supply. It could be caused by a pump that is partially jammed, check that the prop is not stuck to the metal shaft, it should spin and slide up and down on the shaft freely. It can also be the power supply, sometimes if they get dropped the overload detection goes out of whack and it detects a normal load as an overload.
