RESET after release
Manual and automatic reset
If manual reset is selected, resetting can be carried out directly on the device by pressing the
RESET button.
A remote reset (remote RESET) is possible in conjunction with the mechanical and electrical
RESET modules, which are available as accessories. If automatic RESET is set on the
overload relay, the relay will be reset automatically.
Can result in death, serious injury, or property damage.
If a switch-on command is present after an overload trip and a manual reset or automatic
reset is performed, the machine will start up immediately. People may be injured if they stay
in the danger area of the machine.
Make sure that the motor does not start up again following an overload trip until a new
switch-on command has been issued (e.g. via an additional ON button) and that no one is
in the machine danger zone at the time of restarting.
If, in the event of an overload release, the electronic overload relay is used without external
thermistor protection (e.g. 3RN thermistor motor protection relay), the motor may only be
switched in by properly qualified personnel.
