Speed monitor /W
option
We recommend monitoring the speed of the coupling using a speed monitor to avoid
uncontrolled slippage of the coupling and the associated wear to the friction ring pads.
The speed of the output end coupling half of the torque limiting coupling is detected in a
proximity-type method using a trigger cam and an inductive encoder. The speed monitor
compares the pulses with a defined reference speed. The output relay (NC or NO
contact) trips when the speed drops below the specified speed (overload). The monitor
is equipped with a start bypass to suppress error messages during the startup phase.
The start bypass can be set within a time window of 0.5 to 15 seconds.
Reference speed, start bypass and switching hysterisis can be set on the speed monitor.
