What to do if the hook does not stop promptly on my EXE RISE Chain Hoists?
If the hook on your EXE RISE Chain Hoists isn't stopping promptly, it could be due to brake slipping, so you should check the brake. Also, excessive load can cause this issue.
What to do if hook lowers when hoisting control is operated on my EXE RISE D8?
If the hook on your EXE RISE Chain Hoists lowers when you operate the hoisting control, it could be due to phase failure. Also, phase reversal can cause this issue; refer to the installation instructions.
What to do if the hook lowers but will not raise on my EXE RISE Chain Hoists?
If the hook on your EXE RISE Chain Hoists lowers but will not raise, it could be due to excessive load causing the mechanical load clutch to slip. Also, an open hoisting circuit, such as an open or shorted winding in the reversing contactor coil, a loose connection, a broken wire, control station contacts not making, or upper limit switch contacts being open, could be the cause; check electrical continuity and repair or replace any defective part. Phase failure can also cause this issue.
What to do if hook fails to stop at either or both ends of travel on my EXE RISE D8?
If the hook on your EXE RISE Chain Hoists fails to stop at either or both ends of travel, it could be that the limit switches are stuck and not opening the circuits, or they are not adjusted correctly. Check the switch connections, electrical continuity, and mechanical operation, and verify the switch adjustment. It could also be that the limit switch shaft is not rotating; check for damaged limit switch gears and their fixing. Another possibility is that the traveling nuts are not moving along the shaft due to a loose guide plate, or damaged shaft or nut threads; tighten the guide plate screws and replace any damaged parts.
Why is my EXE RISE D8 Chain Hoists motor overheating?
If your EXE RISE Chain Hoists motor is overheating, several factors could be responsible. Check for low voltage conditions and correct them. Excessive load could also cause the motor to overheat, so ensure you are not exceeding the limit. High external temperatures can also lead to overheating; if the ambient temperature exceeds 40°C (104°F), limit the frequency of hoist operation or provide ventilation and shielding. Frequent starting or reversing can also cause overheating; avoid excessive inching, jogging, or plugging. Phase failure or unbalanced current can also lead to overheating. Lastly, check for a dragging brake.
Why does my EXE RISE D8 operate sluggishly?
If your EXE RISE Chain Hoists operates sluggishly, it could be due to several reasons. First, check for excessive load. Low voltage can also cause sluggish operation, so correct any low voltage conditions. Phase failure or unbalanced current in the phases may also be the cause. Finally, a dragging brake can also lead to sluggish performance, so you should check the brake.
What to do if the hook raises but will not lower on my EXE RISE Chain Hoists?
If the hook on your EXE RISE Chain Hoists raises but will not lower, it could be due to an open control circuit, such as a broken or short-circuited "down" contactor coil or a broken "down" limit switch; check electrical continuity and repair or replace any defective part.
Why does the chain move in the opposite direction on my EXE RISE D8?
If your EXE RISE Chain Hoists chain moves in the opposite direction, it's likely due to a three-phase power inversion. Refer to the installation instructions.
Why does the hook stopping point vary on my EXE RISE D8?
If the hook stopping point varies on your EXE RISE Chain Hoists, it could be that the limit switch is not holding its adjustment. Also, the brake may not be holding.
What to do if my EXE RISE Chain Hoists does not respond to the controller?
If your EXE RISE Chain Hoists aren't responding, several factors could be at play. First, check for voltage at the hoist main line and ensure the control circuit switch is closed, replacing any blown fuses. Phase failure due to damaged power or supply cables, or a broken stator winding, could also be the culprit; in this case, check for electrical continuity and repair or replace any defective parts. An open control circuit, perhaps from a blown primary transformer fuse, a broken transformer winding, or a faulty limit switch, could also be the reason. Also, verify that you're using the correct voltage and frequency as indicated on the hoist's identification plate, and check the power supply voltage to rule out low voltage issues. The brake not opening, possibly due to an open, short-circui...
