5.3. Photocell installation (option)
INSTALLATION
It is recommended to install photocells at a height of not less than 20 cm and not more than 2 m.
The photocells must be installed vertically and parallel to each other (see Fig. 6).
The first to be installed and connected is the receiver, and after that - the transmitter.
Move the transmitter when installating, till the photocells become parallel to each other. In
this case, the receiver turn-off lamp will turn off, then fasten the transmitter.
The installation is complete.
CARE AND MAINTENANCE
Due to propagation properties of infrared radiation, an incorrect function of the system is
possible at a small distance between the transmitter and the receiver. The distance between
them should be at least 1 meter. If the receiver sensitivity at a small distance between
the transmitter and the receiver is insufficient, remove the lens of the receiver in order to
increase its sensitivity.
Avoid direct sunlight!
Select the desired mode of the photocells with respect to the control contacts: NO (normally
open) or NC (normally closed). If necessary, change the jumper position NO / NC.
For steady work, the maximum distance between the photocells must not exceed 25 m. In
bad weather (fog, rain, etc.) the coverage may be reduced by 30%
OPERATIONAL RECOMMENDATIONS
Keep photocells clean; if necessary, wipe the front of the sensors from dust and dirt.
At least once a month, check the correct operation of the photocells (in presence of
obstaclesbetween the photocells, the gates should be left open during the commands and
when closing thegate, they have to go to reverse or stop)!
Install a jumper on the photodetector for work with the NC (normally closed) contacts.
