Electrical connection
•
Any wiring, testing and maintenance work
on an open controller shall only be
performed when power has been turned off.
Pay particular attention to the points shown
under "Safety information".
•
The controller must never be operated while
it is open.
•
When the controller has been turned off,
dangerous voltage levels are still present for
up to 5 minutes.
•
During the downtime, no isolation exists
between the amplifier module and the motor
terminal.
•
Touching
electronic
components
is
dangerous due to residual voltages.
•
Never operate the controller while the cover
is removed.
•
When the installation was completed, check
that the system was configured correctly
and that the safety system works properly.
•
The controller may be opened only if all the
poles of the supply voltage have been
turned off. It is not permitted to turn on or to
operate the controller when it is open.
•
Never operate the controller without having
connected the protective earth conductor.
The absence of a protective earth conductor
will result in hazardous voltages on the
controller housing caused by terminal
capacitances. The RFI filters integrated into
the controller may increase the leakage
current up to a max. of 7 mA (see DIN EN
60335-1 section 16.2). A corresponding
routine test was carried out by the
manufacturer before delivery of the device.
•
Hazardous voltages remain stored in the
DC-bus capacitors for up to five minutes
after power has been turned off. The
discharge time until voltages fall below 60
VDC is a maximum of 5 minutes. Touching
internal controller components within this
discharge time is hazardous.
•
If the potential free contacts of the output
relays or other terminals are supplied by an
external voltage, i.e. dangerous voltages
that are still present after switching off the
controller or disconnecting power, you
must attach a suitable warning sign to the
housing.
•
A defective switching power supply can
considerably increase the discharge time
of the DC-bus capacitors before reaching
a voltage less than 60VDC. In this case,
discharge times of up to 10 minutes may
be possible.
•
The processor circuit is galvanically
connected to the power line. Important:
when taking measurements on the
processor circuit, do not use test
equipment with PE reference to the
measuring circuit.
•
The controller must never be operated with
a damaged membrane keypad or Display
window. Damaged keypads and Display
windows must be replaced. 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.
Disconnect all supply circuits before
opening the housing for access to the
terminals.
•
When moving the door in deadman
mode, ensure that the operator has an
unobstructed view of the door area, since
in this mode safety equipment such as
safety edge and photo eyes are
defeated.
•
Parameter settings inclusive the speed
as well as all operations of the safety
devices must be checked. The setting of
parameters, bridges and other operating
elements may only be carried out by
qualified specialists.
