Automatic pool cover torque motor4/2/2024 This misalignment is more common on older systems and rarer (though still possible) on newer ones. If the shifting dogs do not engage each other, the pool cover can not move. Check the shifting dogs (or shifting gears) for accurate alignment.Most modern drive pins are made of hardened steel and should not break, but should be checked regardless. While some systems have a shear pin, technicians should not confuse this with the present drive pin. If the rope or ropes need to be replaced, the technician should check with the individual manufacturer for replacement instructions, as each has different guidelines on replacement procedures. Any part of the rope less than 3.175 mm (0.125 in.) in diameter is showing signs of internal wear and should be proactively replaced at this time. Ropes should always be 6.35 mm (0.25 in.) in diameter. The ropes should then be inspected for exterior wear or diameter inconsistency. In this case, the technician must first untangle the ropes and go back to step #3 to prevent a recurrence. If ropes are tangled, it is very likely due to a lack of tension on the rope reel tension blocks (see step #3). The technician needs to ensure there is enough tension on the rope reels to make turning them by hand somewhat difficult. Check for proper tension on rope reel tension blocks.These bolts are not designed to break, but will fracture if put under an inordinate amount of torque over a prolonged period of time. Broken bolts are an indicator of other problems, not necessarily the main cause of a cover not operating. Check for broken or loose motor coupler bolts.Whether the motor is quick-connected or hard-wired, the connection must be secured. Check for secure electrical connection to motor.After the housing lid has been removed, the motor end of the drive system needs to be checked using the following steps: While it is important to remember each manufacturer’s system is unique, these checkpoints are the best starting point for any technician looking for a mechanical issue with an automatic cover. Of course, since each manufacturer’s product is different, technicians should consult the manufacturer or its manual for repair details. If all of the above steps have failed, the problem lies within the motor or controller. When all else fails, all connections at junction boxes and components need to be rewired. These connection locations are usually the most difficult electrical problems to diagnose and repair. If the shaft does not move and the motor still has no activity, it is time to move on to the next step.Įlectrical issues are not always the motor or controller components, but can be attributed to wiring and/or connections between these components. If this is the case, he or she can skip further electrical diagnosis. If it moves in both directions, but the cover does not, the technician is dealing with a mechanical issue. Next, the controller should be gently operated to see if the motor shaft is able to move in both forward and reverse. The ultimate goal of this process is to determine whether the problem at hand is an electrical issue or an electrical component issue, either the controller or motor. Each location should be investigated until the location of the breakdown has been determined. If it is, he or she should continue to look for power at the next connection, usually a junction box near the motor or controller. The technician should start at the electrical box to see if the breaker is on. If this is not the case, the path of power (or reverse path of power) should be followed. A step-by-step guide to diagnosing mechanical issues on the motor end of the drive system. If no power is present, the problem might be solved in the first five minutes-a tripped ground fault interrupter (GFI) circuit breaker. As such, they are a must-have for any service technician. Not only are these devices handy, they are also affordable they typically cost less than $10. When held against power cords, it will illuminate to indicate whether power is present. Sometimes the most obvious problem can be answered with the simplest question: “Is there power to the pool cover?” The quickest way to test for power is to use an electrical tester pen.
