Troubleshooting
RoboVent unit is making excessive noise. Check the following:
1. Make sure the blower wheel is not hitting the venturi.
2. Check that all venturi bolts are securely tightened.
3. Make sure motor bearings are good. (Amperage rating will be higher than normal.)
Motor Overload will trip frequently/need to be set >then 125% FLA.
4. If the noise is an electrical hum in the control panel, it could be a defective motor
starter relay. Loose connection in motor contact/loose wire
5. Blower wheel could be out of balance. If the blower wheel has gone out of
balance, there will be excessive vibration. In this case, please contact the RoboVent
Service Department at 1-888-762-6836. Blower wheels should only be balanced by
qualified service personnel.
Pulse Filter Cleaning System not operating. Check the following:
1. Check thresholds are set to recommending levels
a. High – 3.0
b. Low – 2.0
3. Verify that the airline is connected to the air tank and that there are no pinched or
clogged airlines.
4. Check air tank pressure at the filter regulator. The pulsing system works best when
pressurized at 85 PSI.
5. Check control pad to make sure Online and Offline pulse are turned on.
6. Manaully check each vale by pressing the manual pulse button and listening for each
of the 10 valves to fire. Default pulse timing is 10 seconds between each valve.
Little or no suction at intake. Check the following:
1. Confirm the set point selected. May need to increase set point to increase suction.
2. Confirm if it is set to Auto Speed Control and what that set point level is.
3. Confirm if it is set to RPM Setpoint and what that set point level is.
4. Check motor rotation. When the unit is powered down note the rotation of the
motor shaft. Motor rotation should be clockwise when viewed from above unit.
5. If motor is spinning backwards, Change Phase A and Phase C on line out side of
VFD. DO NOT change Phasing on disconnect or Overload.
6. Cartridge filters are loaded. Check the Controller reading. Any reading of 6” Water
Column (Collector loading level maximums can vary depending on application,
contact Robovent for specifics on your unit if in doubt) or greater signals that the
cartridge filters could be loaded. Initiate a manual cleaning cycle (see “Operating
your Spire Collector Using the Control Pad”) before replacing cartridges.
7. Check intake damper, if closed, limited suction will occur.
