The devices must be installed in switchgear cabinets complying with degree of pro-
tection IP32, IP43 and IP54, depending on the prevailing environmental conditions.
The products described herein are designed to be components of a customized
machinery safety-oriented control system. A complete safety-oriented system
may include safety sensors, evaluators, signaling units and concepts for ensuring
safe switch-off. It is the responsibility of each manufacturer to ensure the correct
overall functionality of its systems and machines. ABB AG, its subsidiaries and
affiliates (collectively "ABB") are not in a position to guarantee all of the charac-
teristics of a given system or product not designed by ABB.
ABB accepts no liability for any recommendation that may be implied or stated
herein. The warranty contained in the contract of sale by ABB is the sole warranty
of ABB. Any statements contained herein do not create new warranties or modify
existing ones.
The C581 safety switch gear can be used in EMERGENCY-STOP devices
according to DIN EN ISO 13850 and in safety circuits according to VDE 0113-1
and/or DIN EN 60204-1, e.g. with movable guards and protective doors.
Depending on the external circuit, SIL3 according to IEC 61508 or PLe according
to EN 13849-1 can be achieved. Depending on the risk assessment, additional
measures may be required in the sensor circuit (e.g. protected laying of cables).
When using the safety switch gear in the "Automatic Start" operating mode, the
automatic restart (according to EN 60 204-1, Section 9.2.5.4) must be prevented
through adequate measures in the case of an emergency switch-off (EMERGEN-
CY-STOP).
The C581 safety switch gear has three enabling circuits (safe circuits, NO con-
tacts) and a signaling circuit (not safe, NC contact). The number of enabling cir-
cuits can be completed by adding one or more C579 or C579-AC expansion mod-
ules. Two LEDs indicate the operating mode of the device.
When the EMERGENCY STOP button or the limit switch is unlocked and when
the ON button is pressed, the internal circuits of the safety switch gear and the
external contactors are checked for proper functioning.
Connect the EMERGENCY STOP button or the limit switch to terminals T1/IN1
and T2/IN2. The ON button is connected in series with the NC contacts of the ex-
ternal contactor (feedback circuit) at terminals T3/IN3.
Short-circuit protection for enabling and signaling circuits
Be sure to fit the specified fuses. Otherwise safe interruption in
the event of a fault cannot be guaranteed.
On first commissioning or after device replacement, the correct
functioning of all machine/system safety functions must be
checked so that wiring errors and accidental terminal mix-up can
be detected!
For further data and accessories see Catalog.
Read and understand these instructions before installing,
operating, or maintaining the equipment.
