INSTALLATION INSTRUCTIONS
Ensure that the Sender (TX) and Receiver (RX) are at the same level and
are in line with each other.
Securely fix the profiles to the lifting platform walls ensuring passengers
can enter/exit the car without disturbing the profile's positioning.
Securely fix the SIL 2 controller on the platform, ensuring that the control-
ler is grounded.
Connect 12-24 VDC to terminal 3 and 4 in the SIL 2 controller.
Voltage selection is not required, as the controller will automatically adjust.
Connect terminals 1 and 2 in the SIL 2 controller to the platform´s safety
chain. Relays are rated for 4A 250V.
Turn on the power. The green LED in the SIL 2 controller should light
continuously if there is no obstruction between the profiles. The green
LED in the RX should also light continuously.

The WELIG series is designed for static installation only,
on lifting platforms that do not have a cabin door.
The SIL 2 is a safety device, which requires initial testing at the commissioning
stage and regular further testing as part of any planned maintenance program.

· This equipment should be installed only by qualified technicians.
· Carefully follow the instructions in this manual.
· Do not drill the PCB.
WARNING
· Keep connection cables away from high voltage and/or high current wires.
· Avoid direct sunlight or other infrared ingress to the receiver (RX).
· Prior to power-on, clean the lenses with a soft, damp cloth.
· Do not bend or twist the edges, and do not scratch the lenses.
PLANNED MAINTENANCE PROCEDURE
· Ensure that the green LED is lit constantly (system powered up and functioning) in
both the WEBOX and the RX profile.
· Check all plug and terminal connections as well as the output to the safety chain.
· Perform the test procedures outlined below.

The green status LED will immediately start to blink and after 5s the buzzer will
activate, as long as the obstruction is detected.
When an obstacle is detected, the green status LED in the SIL 2 controller
will begin to blink and, after 5 seconds, the buzzer will activate.

WEBOX and WELIG are powered ON
and the green LED is not lit in the RX.
The green LED in the RX profile is
blinking, even though there is no
obstruction between the profiles.
The plastic filter is too dirty.
Other infrared equipment is nearby.
The ambient light is stronger than allowed.
There is a system fault.
WEBOX and WELIG are powered
ON and there is an obstacle between
the profiles but the safety relays do
not activate.
If the green LED is flashing, then the device
is defective and the platform must be shut off.
If the green LED does not flash, check all
connections and recommission the device.
The power supply wires are broken or
incorrectly connected.
The terminal connection is too loose.
The power supply is broken and needs
to be replaced.
The cable is broken or not connected
