cegard/Mini
Trouble shooting
If the cegard/Mini does not operate as expected, observe
the following trouble shooting guide step by step:
1. Switch off the light curtain and then switch it on again
(Power-up for both the Rx and Tx edges)
2. Check supply voltage both on emitter and receiver. Is
the green indicator LED in the emitter edge on and is
the orange LED in the receiver edge on when there are
no obstacles between the emitter and the receiver? Is
the supply voltage between 10 and 30 Volts DC? The
ripple on the DC voltage should not exceed more than
10% of the mean voltage within the min. and max.
range.
3. If the output of the receiver (black wire) is high when
the protected area is not obstructed, and in this case
it should be low, connect the white wire of the receiver
(Rx) cable to 0 V (blue wire, which is also negative
power, page 4).
4. If the output of the receiver (black wire) is low when
the protected area is not obstructed, and in this case it
should be high, connect the white wire of the receiver
cable (Rx) to the positive power (brown wire, page 4).
5. If the output signal of the receiver is not stable during
the closing of the door, make sure that
there is not excessive EMI-noise generated by the
door drive or the door inverter or any other means
that is disturbing the door edge. In such a case,
move the cable of the receiver so that the distance
to the noise source is as wide as possible. In
addition, filter out the noise of the source by using
the optional relay module, the optional power
supply or the power line converter available from
CEDES.
there are no obstacles between the emitter and the
receiver. Make sure that the door lock or any other
obstacle does not enter the light path.
the edges are properly installed and aligned so
that they cannot swing or vibrate and therefore
lose line of sight between themselves.
the optical elements of the edges are clean and not
full of dust or dirt. Although the cegard/Mini is very
tolerant to this condition, its performance is much
better when it is clean.
6. If the doors are closing even with an obstacle
are two possible reasons:
Output selector not properly set (see step 2 and 3)
Faulty / defective system wiring or defective
receiver edge

Due to the nature of door system designs, (which as com-
plete systems is not fail safe), in extremely rare conditions doors
can close even with an obstacle present. Therefore, there must
be, by code, other safety means to prevent passengers from
being hurt by the elevator doors. These dangerous situations
should and can be detected by the elevator control, which
case, take the elevator out of service.

Maintenance
Although the cegard/Mini does not need periodical
maintenance, a functional check at least with every
elevator maintenance check is strongly recommended.
This periodic functional test should consist of the following:
Test the reopening function over the whole door
area. The door should reopen if an object is placed
anywhere between the sill and up to 1,800 mm
(standard configuration) above the sill.
Clean the front surface with a soft towel from dust
or dirt. Especially when the door edges are installed
before the construction of the building is finished
(perhaps weekly during construction). To clean the
surface with a towel, it must be either dry or slightly
moist, but not wet.
Confirm edges are fastened securely to the door wings
and slam post
Confirm cables are routed properly as described in the
appropriate mounting kit installation instructions.
Important notices:
Never use any solvents, cleaners or mechanically
abrasive towels to clean the edge. The plastic lens can
be damaged!
Although the edges are water and weather resistant,
never use lots of water to clean the edges!
Never use high pressure water to clean the edges!
Do not scratch the surface when cleaning the edges!
Disregard of the mentioned precaution may lead to a loss
of safety!
Disposal
The light curtain should only be replaced if a similar door
protection device is installed. Disposal should be done
using the most up-to-date recycling technology according
to local rules and laws. There are no harmful materials
used in the design and manufacture of the light curtain.
Traces of such dangerous materials could be used in
the electronic components but not in quantities that are
harmful to health.

This device (as well as all other door protection systems on
the market) cannot – by its nature – provide absolute safety for
elevator passengers passing through the doorway. It must not
be used as the final fail safe device of the door mechanism.
This ultimate safety function has to be provided by a fail safe
force and kinetic energy limiter.
