The supply is a Condor...
Model HC5-6/OVP-A+
Input 120/240
0.9/0.5 amps
Output 5VDC @ 6amps
Here is my problem.
My 5volt dc supply is tripping out. Cycling the power to it restores it working immediatly.
It is now plugged into a battery backup unit with the computer. (its a small batter backup but it works).
The 5 volt supply is still tripping. It only seems to do it when the 480v 3ph motor shuts off after hitting a 24volt limit switch. (powered by the 24vdc Condor supply that works just fine)
The 5vdc supply will be on for HOURS, doing nothing really.. If I go around the machine and flip limit switches by hand, the OPTO relays turn on and off just fine. (they are powered by the 5volt supply)
But when the 480volt motor is operating, and gravity is working against it, the 5 volt supply will trip the second the mechanical movement hits the upper limit switch.
It does not trip when it hits the lower switch.
The mechanical action hits the upper switch, the motor shuts off (as the computer tells it to) and my 5volt supply trips out all at the same time.
The only thing the 5volt supply is hooked up to is the Opto22 relay boards and my ICM2900. There are 2 boards.
A G4PB32DEC and a PB16T and of course it powers the ICM2900.
When the supply is running, it is cool to the touch.. when it trips, it gets warm and continues to get warmer the longer I let it go before cycling the power on and off. Once I cycle the power, it turns back on immediatly and begins to cool off.
A multimeter says its pulling less than 200 milliamps when it blows.
Any ideas?
Thanks,
Murphy
