5.2.1. Criss-cross beam mode (Jumper JP1)
JP1 set = Criss-cross beam mode on
JP1 off = Criss-cross beam mode off
With the criss-cross beam mode on, the smallest
object size detected is in the area of high resolution.
In this area the minimum object size detected is
equivalent to half the element separation distance,
plus 7 mm (beam diameter). In order for the criss-
cross mode to function properly a minimum
operating distance must be obeyed.
With the criss-cross beam mode off, the response
time is reduced. Minimum object size detected in
this mode is equal to the element separation
distance, plus 7 mm (beam diameter).

5.3. Test input

Only for control unit with test input.
This system can be compared with a testable light
barrier. When a test input is made, it triggers a test
and the relay is switched. This must be evaluated by
a super-ordinated control unit. To ensure the system
functions failure-free, the test input has to be
connected to 24 VDC.

Maintenance

Although
periodical maintenance, a functional check at least
with every elevator object 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 top element 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!
Despite having a test input, the system is
not a safety product according EN 954-1!
