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!
If the device has been subjected to improper or
incorrect use it must no longer be used, and the
guarantee loses its validity. Impermissible
conditions include:
strong mechanical stress, for example through a
fall, or voltages, currents, temperatures or
humidity outside of the specifications.
Before starting up your machine/plant for the
first time, please be sure to check all the safety
functions according to valid regulations, and
observe the specified test cycles for safety
equipment.
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 EN 60529.
Housing/terminals: IP 40/ IP 20.
Finger-proof acc. to EN 50274.

Device and Function Description
With the supply voltage applied to terminals A1/A2 and the E - Stop circuit closed, the control logic
is activated by closing the contact of the RESET button. This last controls the K1 to K4 relays that
after the response time t
become self - locking. After this switch - on phase the three safety paths
A1
at the output 13/14, 23/24 and 37/38 are closed. Three LEDs display the status of the K1/K2,
K3/K4 internal relays and the power supply. If the E - Stop contact switch is opened the current
leads for the K1 and K2 relays are interrupted. The enabling current paths 13/14, 23/24 at the
output are immediately opened (after their release time t
stays closed during the preset off - delay time t
- channel connection of the E - Stop switch and cross monitoring wiring of the E - Stop circuit, it is
possible to monitor the presence of a short circuit between the connected cables (cross monitoring)
and ground faults. An internal electronic circuit protects the device relay from damages. After
eliminating the fault the item will return into operation after about 3 s.
RESET button monitoring
The device is equipped with the monitoring feature for the RESET key. The device can be enabled
with the falling edge (RESET released) or rising edge (RESET closed) of the signal (terminals S34 or
S35). For the specific use in the emergency stop applications with manual START the RESET but-
ton must be connected to terminals S33/S34. The device is enabled only with a falling edge of the
RESET signal. In order to start the RESET button has to be closed and released. For those applica-
tions with protective gates where an automatic RESET must be performed, it is necessary to
jumper terminals S35 with S35. The device will react at the rising edge of the input signal at S12
which is internally connected to S33.
Synchronous check
The use of safety limit switches for single or dual channel circuit in the protective gate application
depends from the required safety level. The device features a dual channel control and in addition
a synchronous check of the limt switches on request. Precondition for a simultaneity check t
the position of the limit switches. The limit switches must be positioned so that channel 1 (terminals
S11/S12) has to close before channel 2 (terminals S21/S22) does. If channel 2 closes before channel 1
