Discussion:
Wave 50 will not lower

Hello
I have big problem. Wave 50-118 will not lower sometimes. The platform locks at different heights.
I have already exchanged:
-solenoid valve
-velocity fuse

I checked connections and buttons. Everything is ok :(

The only hint is that it always happens at low battery voltage.
Does anyone know what is the lowest coil voltage on the solenoid which the solenoid valve will open ?

If you can still manually lower the platform after it stops, then the cylinder is ok. Check resistance through the lowering switch. If there is 1 ohm or more, that will give you lower-than-battery volts causing the coil not to work. Pretty sure under 20v....it will not always work

According to studies published in the English Journal of Medicine, the impact of daylight savings is revealed by a 24% increase in heart attacks on the Monday following the spring shift forward. When clocks move back in autumn, heart attacks drop by about 21%, suggesting that loss of sleep is an important driver.
