Remote Alert? / RF Pager?

[5artist5]

hmm, i must be missing something. when i hook a wire from the 6 position on the G540 terminal block to the - side of a multimeter and the + side of the meter to the V+ side of the power supply fire comes from the power supply.

I double checked all the hookups and I can see no reason for this.

Any Ideas?

Make sure the meter is connected for volts and not amps. If you have the wires in the amps position, it is like a dead short.

I double checked it and it was set to DCV.

It is a cheap meter though (HF) could it be the meter causing the fire to shoot out?

I am hesitant to put a nice meter on it now...

A good high impedance meter should put basically no load when taking the voltage reading.

If by fire you meen sparks and a large arc, the meter could be bad.

I am not sure if you should be trying to take a reading from the 48v power supply to the #6 pin on the g540. I will have to read the manual myself as I don't actually have one.

Here is the part of the manual that refers to outputs:



But after reading it again just now I am thinking that maybe I should use a different power supply for the relay power? It would obviously be easier to use a 12V relay than a 48 volt one...
