SubDrive/MonoDrive Troubleshooting (Continued)
SubDrive15, 20, 30, MonoDrive, and MonoDriveXT (NEMA 3R)
Troubleshooting
| Condition | Indicator Light | POSSIBLE CAUSE | CORRECTIVE ACTION |
| LOW PRESSURE | GREEN MOTOR FREQUENCY ON DISPLAY | - Pressure sensor setting, pump rotation, pump sizing - High temperature | - Adjust pressure sensor, check pump rotation - Check frequency at max flow, check max pressure - High ambient and/or drive temperature will cause drive to foldback power and run with reduced performance |
| HIGH PRESSURE | GREEN MOTOR FREQUENCY ON DISPLAY | - Pressure sensor setting - Shorted sensor wire | - Adjust pressure sensor - Remove sensor wire at Pressure Input Board, if drive stops running, wire may be shorted - Remove sensor wire at Pressure Input Board, if drive continues to run, replace Pressure Input Board - Remove sensor wire at new Pressure Input Board, if drive continues to run, replace drive - Verify condition of sensor wire and repair or replace if necessary |
| AUDIBLE NOISE | GREEN MOTOR FREQUENCY ON DISPLAY | - Fan, hydraulic, plumbing | - For excessive fan noise, replace fan - If fan noise is normal, drive will need to be relocated to a more remote area - If hydraulic, try raising or lowering depth of pump - Pressure tank location should be at entrance of water line into house |
| NO DISPLAY | NONE | - Display board cable disconnected or loose | - Verify cable connection between main control board and display board |
| CANNOT CONNECT TO DRIVE WI-FI | FE Connect light on solid | - Attempting to connect to incorrect drive - Out of Wi-Fi range of drive | - Ensure the Wi-Fi SSID (hotspot name) you are connecting to matches the drive you wish to connect to - Wi-Fi range is 100 feet line-of-site, must be closer to drive if walls or floors are between you and the drive - Wi-Fi module not responding, cycle power to drive - Cycle Wi-Fi radio on mobile device, refresh Wi-Fi connection list |
| FE Connect light off | - Wi-Fi timeout expired | - If more than fifteen (15) minutes since last power cycle, cycle power to drive - If more than one (1) hour since last disconnection from Wi-Fi, cycle power to drive | |
| RFI-EMI INTERFERENCE | GREEN MOTOR FREQUENCY ON DISPLAY | - Poor grounding - Wire routing | - Adhere to grounding and wire routing recommendations - An additional external filter may be needed. See Accessories section for ordering information |
