The table below provides guidance on identifying and correcting any problems with your Model B-30 Bollard system. Please refer to the HPU O&M manual for more detailed troubleshooting guides referring to the pumping unit. If you encounter problems that you cannot fix, contact B&B ARMR and we will gladly work with you to correct them.
| Symptom | Actions |
|---|---|
| Bollard does not raise | 1. Check power. 2. Check overload protector. 3. Check pressure gauge. 4. Manually raise the bollard by depressing the directional control valve to see if problem is mechanical or electrical. Q. If mechanical: 5. Check for binding between moving plate and frame. Check connection of linkage between frame and plate. Check for foreign debris. Q. If not: 6. Check PLC input 7. Check that safeties are clear. 8. Check PLC output. 9. Check push button operation. |
| Bollard does not close | 1. Check power. 2. Check overload protector. 3. Check pressure gauge. 4. Manually close the bollard by depressing the directional control valve to see if problem is mechanical or electrical. Q. If mechanical: 5. Check for binding between moving plate and frame. Check connection of linkage between frame and plate. Check for foreign debris under bollard cylinder. Q. If not: 6. Check PLC input. 7. Check that safeties are clear. 8. Check PLC output. 9. Check push button operation. |
| HPU pump will not build up pressure but is running | 1. Check power. 2. Close pressure relief valve. 3. Motor is running backwards (counterclockwise). Motor should be running clockwise. |
| HPU pump will not turn on | 1. Check incoming power and power to motor. 2. Check motor overload, press start. 3. Check motor starter. 4. Check low level switch. 5. Check pressure switch. |
| Bollard makes noise during operation | 1. Check delrin guides and properly lubricated (dry graphite spray). 2. Check hydraulic cylinder celvis pins for lubrication (multi-grade grease). |
| Hydraulic unit is excessively hot | 1. Check that the pressure relief valve is closed (fully clockwise). 2. Check that the pressure switch is adjusted to shut the motor off before 1900 PSI. 3. Check for correct voltage. |
| Bollard moves too slowly | 1. Check for mechanical binds. 2. Check flow control valve. 3. Extreme cold temperatures. |
| Traffic indicator light does not change | 1. Check proper limit switch operation. 2. Check bulbs. 3. Check PLC outputs. |
