Hi,

Just seen an alarm on one of our close control downflow units in a comms room, the alarm is "Al 40 Probes error driver 1" The manual says it's either the suction pressure transducer or the suction line temperature probe, how do I determine which one is at fault?

cheers

Hi Boulting
I assume the temp probe would be the easiest to access.
So removing it and warming it should show a change?
Or you could just disconnect either and see what happens!
