WARNING:
HAZARDOUS VOLTAGE
CAN CAUSE ELECTRICAL SHOCK
AND BURNS.
DISCONNECT POWER BEFORE PROCEEDING
WITH ANY WORK ON THIS EQUIPMENT.
Application
You can use the safety controlgear C576 in safety circuits as per VDE 0113
Part 1 (11.98) or EN 60 204-1 (11.98), e.g. with movable covers and guard
doors; the safety controlgear C577 in EMERGENCY STOP devices as per
EN 418. Depending on external connections, category 4 as per DIN EN
954-1 is achievable.
Functions and connections
The safety controlgears C576/C577 have two release circuits (safety cir-
cuits) configured as NO circuits. The number of release circuits can be
increased by adding one or more C579 expansion units. Three LEDs indicate
operating state and function.
When the EMERGENCY STOP button or the limit switch is unlocked and
when the ON button is pressed, the internal circuit of the safety controlgear
and the external contactors are checked for proper functioning.
On the C577, the ON circuit Y33, 34 is checked for short-circuit. This means
that a fault is detected when Y33, 34 is closed before the EMERGENCY
STOP button is closed.
Connect the EMERGENCY STOP button or the limit switch to terminals Y11,
12, 21, 22. Connect the ON button in series with the NC contacts of the
external contactors (feedback circuit) to terminals Y33, 34.
