there is usually a resistor/diode around the brake coil, have you tried decreasing the resistance? if so, i have had a few over the years, that do this, remove the diode from the brake circuit, brake will drop immediately after relay drops. have done it a few times, and it works great

there is usually a resistor/diode around the brake coil, have you tried decreasing the resistance? if so, i have had a few over the years, that do this, remove the diode from the brake circuit, brake will drop immediately after relay drops. have done it a few times, and it works great although you will probably have to adjust the floor level on auto if it is a composite controller.

FYI: decreasing the resistance allows the brake to circulate more current and stay up longer. If you want it to drop sooner increase the resistance. Completely removing the resistor diode on a brake circuit can rupture other solid state diodes. The typical inductive kick from a brake coil can reach 16,000 volts for a couple nanoseconds and most Rectifiers have PIV of 1000 volts. It will soon rupture solid state components. Rule of thumb for the resistance to protect but not hold is a Minimum of 10-20 times the resistance of the brake coil.

thanks for the info rolly, bad advice on my part. i have had it backward for some time now, i guess increasing the resistance makes sense now that you explained it. i do know about the emf from the brake coil collapsing, and have removed the diode on smaller brake coils, but again i guess i should have found the original problem instead of masking the situation. thanks for putting me in my place you obviously are quite a smart elevator man. i will try and think about what i am posting next time.

We are all here to help others. Takes teamwork to analyze problems. No one person knows it all. We all get stuck in ruts and need another opinion from time to time to get the blinders off. There are a lot of very smart Elevator Men on this forum.
