EMERGENCY OFF category 0; 230 V AC or 24 V DC (option L57)
Description
EMERGENCY OFF category 0 for uncontrolled stop according to EN 60204-1. This function
disconnects the cabinet unit from the power supply via the line contactor, while bypassing
the electronics by means of a safety combination according to EN 60204-1. The motor then
coasts to a stop. To prevent the main contactor from switching under load, an OFF2 is
triggered simultaneously. The operational status is indicated by means of three LEDs (-
K120).
When delivered, the type with 230 V AC pushbutton circuit is set.
Note
When the EMERGENCY OFF pushbutton is pressed, an uncontrolled stop of the motor
takes place and the main motor voltage is disconnected in accordance with EN 60204-1.
Auxiliary voltages (e.g. for separately-driven fans or anti-condensation heating) may still be
present. Certain sections of the converter (e.g., the closed-loop controller or any auxiliary
equipment) also remain live. If all the voltages have to be completely disconnected, the
EMERGENCY OFF pushbutton must be integrated in a protection concept, which must be
implemented on the line side. For this purpose, an NC contact is installed at terminal -X120.
