Glad I got to use a 20% off coupon when I purchased the table, this helped to make the extra work to make the table work more bearable. The control transformer fuse is blown. Some of the add-ons on this site are powered by. Make sure that the coil is energized when the down valve button is pushed. When the cables become loose, the power within them becomes intermittent, meaning that sometimes the power can flow through them and sometimes it cant. Step 4: Check the continuity of the coil; if it isnt working, your scissor lift could be experiencing a problem with its solenoid. However, if the motor start solenoid is damaged, the lift will fail to perform properly. The voltage may be low. Check for low oil level or clogged breather holes in reservoir fill plug. Lower lift to closed position and continue to hold DOWN button an additional 10-30 seconds to bleed air from cylinder. If the hydraulic lift is stuck in the up position, there are high chances that the control valve has been jammed. Oil line, hose, or fitting may be leaking. From manuals to instructional videos, a glossary of terms to an FAQ of your burning questions, we have all the resources you need to be successful with your lift. Moreover, you must monitor the cooling compartment as well as the heat exchanger to make sure they are working properly.

Your desk should automatically turn back on and begin functioning as normal. 
In addition, if some components are damaged and cannot be tightened with a bolt, you will need to hire a mechanic to weld these parts. While one motor may turn, the second will either remain still or turn more/less than the first motor. While being in reset mode, a sit stand desk can only travel downwards. Foreign material clogging suction filter, breather cap or pressure line, Pump may be overheating due to insufficient oil, Down valve may not be fully open or stuck closed. My Blog: .

If a single-phase motor is being run more than 15 20 motor starts per hour, or a 3-phase motor more than 200 starts per hour, the problem may be motor over-heating. Use the checklist below. This is indicated by the pump shaft and motor turning backward on their own with no power applied. Supply voltage should be +/- 10% of the rating at the motor terminals. Here are photos of the taken apart valve and a close up of the release "button" that I end up filing down. Check voltage near coil. Do not check at the line source or while the pump is idling. Any other suggestions or experiences would be greatly appreciated. The load may exceed the bridge rating. Meet our team of professionals from each department. I missed this thread before. Every height adjustable table has a maximum lifting capacity. Most of Autoquips standard motors are rated for intermittent duty (two minute run times with two minute rests). The main disconnect switch / distribution panel circuit breaker is tripped or a fuse is blown. If it trips again, check for cause in the motor circuit. It is suggested that you inspect the lift, particularly around the arm and hydraulic system, to tighten up the loose bolts, if any. The chain may be off of a sprocket. Check wiring to the down valvle. If the tilter does not lower after trying Step 2, wait approximately 10 15 minutes for the pressure in the hydraulic system to equalize.
