Safety Instructions
Device and Function Description
With the supply voltage applied to terminals A1/A2 the relays K3 and K4 are immediately energized (ter-
minals 37/38) according to the pre selected on-delay time. The on-delay time t
A1
can be adjusted from
0,15 through 3 s or 1,5 through 30 s according to the selected device. The activation of the device is done
by the RESET switch. Two operation modes are available:
Operation mode with RESET switch monitoring
(manual START, evaluation of the falling edge of the
signal)
The RESET switch must be connected to terminal S34 via S33. The device starts by closing the RESET
switch. The relays K3 and K4 (terminals 37/38) go to their off position. With the falling edge of the signal
(RESET switch released) the RESET controls the K1 and K2 internal relays that after the on-delay time t
A3
become self-locking. After this switch-on phase the two safety circuits at the output 13/14, 23/24 are
closed. With the activation of the STOP command the current leads for the K1 and K2 relays are inter-
rupted. The enabling current paths 13/14, 23/24 at the output are immediately opened (after their release
time t
R
) and the internal relays K3 and K4 are energized after the pre selected on-delay time (t
A1
) has
elapsed. The enabling current path 37/38 is closed.
Three LEDs display the status of the K1/K2, K3/K4 internal relays and the power supply.
Operation mode without RESET switch monitoring
(automatic START, evaluation of the rising edge of
the signal)
For monitoring of interlocking devices with tumbler and those applications with protective gates where
an automatic RESET must be performed, it is necessary to jumper terminals S33 with S35. The device will
react at the rising edge of the input signal at S12 which is internally connected to S33. The relays K3 and
K4 (terminals 37/38) go to their off position. With the rising edge of the signal at S12 the relay K1 is ener-
gized and the on-delay time t
A2
is started. In this case the two enabling current paths at the output (ter-
minals 13/14, 23/24) are closed after the time t
A2
has elapsed. With the activation of the STOP command
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
R
) and the internal relays K3 and K4 are ener-
gized after the pre selected on-delay time (t
A1
) has elapsed. The enabling current path 37/38 is closed.
With a two-channel connection and cross monitoring wiring of the transducer in 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.
Synchronous check
The use of safety limit switches for single or dual channel circuit in the protective gate application de-
pends from the required safety level. The device features a dual channel control and in addition a syn-
chronous check of the limit switches on request. Precondition for a simultaneity check t
S
≈
0,5 s is 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 or S11/S31) does. If channel 2 closes before
channel 1 the simultaneity time t
S
=
.
Please observe instructions from safety authorities.
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.
