Troubleshooting
Overload is Tripping
1. Confirm the FLA of the motor and that the overload is set to 125% of the FLA.
2. Multiply the FLA * 1.25 to set overload amperage.
Cartridge filters load up but no dust in the dust tray. Check the following:
1. Check that the Pulse Filter Cleaning System is working properly.
2. Check for oil or moisture on the filter media. If oil or moisture exists in the air supply,
it will transfer to the cartridge.
3. In some cases, very high oil content is present on the surface of the steel stock, and
the cutting process may cause the oil to vaporize. This will cause the cartridge filters
to load up prematurely. In this situation the best solution is to remove most of the
oil from the steel before it is processed. Call the RoboVent Service Department at
1-888-762-6836 for more information.
HMI display reads “0” or has a consistently low reading for Filter Pressure.
1. Check that the plastic tubing from the Controller has not come loose from either of
the barbed ends on the pressure transducer.
2. Check for a pinched line in the plastic tubing from the Controller.
3. Remove tubing from pressure transmitter connection barbs and blow air into the
¼” plastic tubing lines with low pressure away from the transmitter. Dust particles,
insects and dirt can get into the tubing and prevent an accurate reading.
4. In some cases, the Pressure Transducer will need to be replaced.
Smoke Detector Alarm Sounds*:
1. Alarm trips – Audible alarm, red light on control cabinet is red, alarm button on
control pad is red. Press Log on HMI screen for detail of what alarm tripped. If smoke
is detected follow below.
a. Power to motor is turned off by the onboard control system, and the audible
alarm goes off alerting you of a shutdown. The Andon light on the cabinet door
will turn red.
b. If the unit is equipped with the Supprex-200 Fire Suppression system, intake
dampers will close, sealing off the unit. The intake damper is fail-safe and will
close either when the unit goes into alarm, or when power is cut off to the unit.
c. Turn power off at the main disconnect for the unit.
d. Turn the compressed air supply off to the unit.
