4-30 Operating Manual
4.9.7 EMERGENCY OFF Category 0; 230 V AC or 24 V DC (Option L57)
Description
EMERGENCY OFF category 0 for uncontrolled stop to EN 60 204. This function
involves disconnecting the cabinet from the supply via the line contactor bypassing
the electronics by means of a safety combination to EN 60 204-1. The motor then
coasts to a stop. To prevent the main contactor from switching under load, a pulse
block is triggered at the same time via an external fault. A restart is only possible
after the fault has been acknowledged. The operational status is indicated by
means of three LEDs.
In the factory setting, this version is set with a 230 V AC button circuit.
