3 Safety functions in accordance with EN 12453:2017
EN 12453:2017 places special requirements on safety-related signals. These signals must comply with a
minimum of PL “c”, cat. 2 in accordance with EN 13849-1. To guarantee these safety requirements, the
complete chain of sensors, actors and if necessary, the wiring must be taken into account accordingly. This
affects (amongst others):
•Path restriction units (limit switch)
•Actuators with automatic reset
•Slack rope switch
•Slip door switch
To comply with these standard requirements, these signals can be connected via the Emergency-Stop inputs
of the controller (terminal no. 31-32 and 41-42).
Alternatively, standard digital inputs can be used. In this case, an additional output must be configured as a
test output and integrated in the signal chain.
3.1 Connection example testing
In this example, the testing is described using a
transmitter-receiver light barrier.
The transmitter is supplied with 24 V via a test
output.
In a test case, the output is switched off so that
the transmitter is voltage-free.
The receiver now switches the input.
The controller checks whether the input really
switches and switches back.
If YES, the test was successful, if NO, error F.928
is set.

damaged controller may result in significant consequential damage to the controller as well as hazards to
the user.
•The controller must never be operated with a damaged membrane keypad or Display window. Damaged
keypads and Display windows must be replaced.
•Do not touch any electronic parts, in particular the components of the processor circuit. Electronic
components can be damaged or destroyed by electrostatic discharge.
•Before opening the cover of the housing, ensure that no drilling swarf can fall into the housing from the
cover.
•When installing the controller it is important to ensure that it is not subject to mechanical stresses.
•Unused cable entries must be sealed to maintain the requirements of IP54.
•In large housings (controller variants -CGH, -CXGH, -LGH) , the screw on the frame near the motor
connection must be tightened to ensure the IP65 protection rating of the housing (tightness).
•The cable entries must not be exposed to any mechanical stress, such as tensile loads.
•The controller must never be operated without the CEE-plug except when the supply voltage can be cut
all poles by an installed main switch. The main switch and the CEE-plug must be within easy reach.
•A not rotating motor is no indication of the galvanic isolation from the power grid! The mains connection
terminals, motor terminals and terminals for the brake resistor can still carry dangerous voltages, e.g.
under stop or emergency stops.
•If the supply cable is damaged, it must be replaced by the manufacturer or another qualified person in
order to avoid danger (like connection type Y EN 60335-1)
•When moving the door in deadman mode, ensure that the operator has an unobstructed view of the door
area. In this mode, safety equipment such as safety edge and photo eye may have been defeated. If this
is not possible for structural reasons, you must ensure that this mode is only accessible to appropriately
trained personnel or that the feature is disabled altogether.
•To prevent damage to the keypad, do not use pointed objects to operate the keys. The keypad is only
designed to be operated by human fingers.
•Depending on the type of the door it may be necessary that the door can only be operated when it is
within visual range. In these cases, no remote control (e.g. wireless) may be used to issue commands.
•It is important to ensure that the controller is installed with the wall spacers that are supplied to guarantee
that the power stage can dissipate heat as necessary.
•The control unit should not be mounted on flammable surfaces (e.g. wood ≤ 2 mm thickness) or in
environments with highly flammable substances (e.g. carpentry).
•When the controller is installed in an additional housing, e.g. in a barrier housing, a sufficient air volume
of at least 0.02 m3around the controller must be ensured.
•Should cooling not be sufficient, an additional heat sink may be inserted between the controller housing
and the additional housing to dissipate the heat to the outside (see chapter 5.2 Additional heat sink for
small housing).
