6 ALIGNMENT PROCEDURE.
After having carried out the correct mechanical assembly and the correct
connections as described in the previous paragraphs, it is necessary to
align the pairs of photocells. Follow the operative modes as follows:
•
Turn off the power supplying the control unit.
•
Open the TEST pushbutton.
•
Power the control unit.
•
Align the photocells by observing the LEDs on the control unit: If the
alignment of the relevant pair of photocell is correct, the
corresponding LED will turn on.
•
After the alignment, turn off the power supplying the control unit,
close the TEST pushbutton and re-power the control unit again.
•
Wait for the control unit to carry out the initial tests.
•
At the end of this operation, the unit indicates the right alignment
with the guard led green on.
•
Carry out all the checks described in the final checks and in the
routine maintenance operations.
During aligning operations or normal working, check that the photocells
connected to the same or other units do not interfere which each other,
modifying their mutual position, for instance by positioning some pairs of
transmitters on the other receiver side.
NOTICE
The control unit can detect the mutual interference between safety PESs. The
control unit forces the output contact to open, when it detects external
disturbance light including mutual interference light.
The safety PESs should be installed the following way to avoid mutual
interference.
- The safety PESs are installed with sufficient distance.
- Emitters and receivers of safety PES are installed alternately as follows:
