Instructions
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 controlgears C571/C573 in EMERGENCY STOP
devices as per EN 418 and in safety circuits as per VDE 0113 Part 1 (11.98)
and/or EN 60 204-1 (11.98), e.g. with movable covers and guard doors.
Depending on the external connections, categories 3 and 4 (with additional
external measures) as per DIN EN 954-1 are achievable.
Functions and connections
The safety controlgear C573 has three release circuits (safety circuits)
which are configured as NO circuits and a signal circuit configured as an
NC circuit.
The safety controlgear C571 has two release (safe) circuits which are confi-
gured as NO circuits. The number of release circuits can be increased by
adding one or more C579 expansion units. Three LEDs indicate the opera-
ting state and function.
When the EMERGENCY STOP button or the limit switch is unlocked and
when the ON button is pressed, the internal circuits of the safety controlge-
ars and the external contactors are checked for proper functioning.
Connect the EMERGENCY STOP pushbutton or the limit switch in the supply
cable from A1 to +24 or L24 V. To evaluate over two channels, connect
Channel 2 from A2 to 0 V or N. Connect the ON button in series with the NC
contacts of the external contactor (feedback circuit) to terminals Y1 and 2
(for circuit examples, see Figs. IV to VII).

Control supply voltage
The safety controlgear is protected by an internal self-healing
PTC fuse (multifuse).
Be sure to fit the specified fuses. Otherwise safe interruption
in the event of a fault cannot be guaranteed.
