Troubleshooting
HVE Hi-Vac Machine shuts down.
1. If all intakes are closed the HVE Hi-Vac Machine may go into fault mode. In this case
the VFD will need to be reset. This is an amperage overload fault to protect the
turbine from burning up. Note that your turbine will always need air going into the
intake to allow blower cooling. If not, the turbine will shut down the whole system.
Make sure the inlet Surge Filter is clean.
2. If equipped, check the Safe Sensor. If there is excessive particulate or smoke present
in the clean air side of the collector the Safe Sensor will go off and shut down the
system. Check for a cartridge filter fire or a hole or gap in the filter. If particulate
passes the filter media the Safe Sensor will go off, shutting down the system.
Cartridge Filter loads up but no dust in the dust tray.
1. Check that the PowerFlex is working properly and that the parameters on the ePad
Controller are set 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 high oil content is introduced in the welding process causing the
oil to vaporize. This will cause the cartridge filters to load up prematurely. In this
situation a specialized filter may be needed. Call the RoboVent Service Department
at 1-888-ROBOVENT.
4. Check for re-entrainment. Run a Manual Pulse-Down Cycle on the ePad Controller.
When finished record how much particulate is in the 20 gallon bucket. Replace the
bucket and run the system for one minute. Shut off the HVE Hi-Vac Machine with
the Power Disconnect. Remove the 20 gallon bucket and compare the particulate
level. If the level has reduced by 30-40% then there could be an air leak in or around
the flex hose or bucket cover. Check for leaks and plug with Vulkem. Allow to fully
dry before restarting the HVE Hi-Vac Machine.
Differential Pressure Gauge consistently displays a high reading.
1. Check for a pinched line in the blue plastic tubing from the Minihelic Gauge.
2. Make sure the hoses to the Differential Pressure Monitor on the back of the ePad
have not been switched or removed. There should be 2 hoses.
3. Check for loaded cartridge filters. Clean or replace if needed.
