Safety Instructions
Only trained professional electricians may
install, startup, modify, and retrofit this
equipment! Disconnect the device / system
from all power sources prior to starting any
work! If installation or system errors occur,
line voltage may be present at the control
circuit in devices without DC isolation!
Observe all electrical safety regulations
issued by the appropriate technical authorities
or the trade association. The safety function
can be lost if the device is not used for the
intended purpose. Opening the housing or
any other manipulation will void the warranty.
Caution!
Perform the following precautionary steps
prior to installation, assembly, or disassembly:
1. Disconnect supply voltage to the
equipment / system prior to starting any
work!
2. Lockout/tag the equipment / system to
prevent accidental activation!
3. Confirm that no voltage is present!
4. Ground the phases and short to ground!
5. Protect against adjacent live
components using guards and barriers!
6. The devices must be installed in a
cabinet with a protection class of at least
IP 54.
Caution!
Limited contact protection! Protection type
according to DIN EN 60529.
Housing/terminals: IP 40/ IP 20.
Finger-proof acc. to VDE 0660 Part 514.

Description of Device and Function
This device is a two-channel safety switching device with self-monitoring on each ON-OFF cycle.
It conforms to EN 60204-1 and is equipped with positively driven relays. It is intended for
monitoring connected switching elements on separating safety devices and generating a safety-
oriented output signal (enable). Depending on the design, separating safety devices may include
protective screens, safety doors, enclosures, covers, screens, etc.
Basic function: After supply voltage has been connected to terminals A1/A2 and the safety
inputs closed, operating the reset button closes the enabling current paths (manual start). When
the safety inputs are opened the enabling current paths will open.
Operating modes / system functions
•
Two-channel activation The device uses two-channel activation. With equivalent activation
safety channel CH1 is connected via positive potential, safety channel CH2 via negative
potential. With non-equivalent activation both safety channels are connected to positive
potential.
•
Cross monitoring With equivalent activation cross monitoring is achieved by means of the
short-circuit principle; with non-equivalent activation it is achieved through functional
diversity.
•
Manual start When the safety inputs are closed, a button is used to close reset input S34
and then open it again (triggering with falling edge) or to close reset input S35 (triggering
with rising edge).
•
Automatic start Reset input S35 is connected to S33/S14. The device starts with the rising
edge of the signal on safety input S14.
•
Starting lockout After supply voltage has been connected and the safety inputs closed, the
enabling paths will not close. Starting is only possible after the reset button has been
operated. For starting lockout the reset inputs have to be activated with the button, as in
manual start mode.
•
Restarting lockout No restart after the safety inputs have been opened and closed.
Restarting is only possible after the reset button has been operated. For restarting lockout
the reset inputs have to be activated with the button, as in manual start mode.
•
Synchro-check Synchro-check is only possible in automatic start mode (bridge S33/S14 -
S35). After safety channel CH1, safety channel CH2 must close (S24) or open (S22) within
the synchronous time t
Please observe instructions from safety authorities.
