Chain Installation Guide: Power Supply, Master/Slave Setup & Photocells
Photocells for Chain: Types and Installation
There are two types of photocells used with the Chain system, depending on the installation length:
-
Battery-powered photocells – for Chain systems up to 10 m
-
Wired (classic) photocells – for Chain systems from 10 m to 20 m
The main reason for using battery-powered photocells is installation simplicity. However, they do not operate efficiently at distances greater than 10 meters. For installations exceeding 10 meters, wired photocells must be used.
1. Battery-Powered Photocell (Chain up to 10 m)
For Chain installations up to 10 meters, a battery-powered photocell can be used.
Installation Requirements
During installation, batteries must be inserted into the photocell located on the slave unit. Standard AA batteries are used, with an average lifespan of approximately one year. After that period, the batteries should be replaced to ensure proper operation.
The battery-powered photocell should be mounted on the slave unit and batteries should be inserted. Find photo of battery powered photocell in Image 1. Master unit photocell is always mounted and connected in production.
2. Wired Photocell (Chain from 10 m to 20 m)
For Chain installations longer than 10 meters, a wired photocell is mandatory.
Preparation Requirements
During the preparatory phase (before installing the Chain), it is necessary to route:
-
2 cables of 0.5 mm² from Master to Slave unit of Chain
After the Chain installation is completed, the photocell on the slave unit must be connected according to the wiring diagram provided in the Image 3.
This setup ensures stable and efficient operation at longer distances.
Conclusion
Choosing the correct photocell type depends on the Chain installation length:
-
Up to 10 m – battery-powered photocell
-
Over 10 m – wired photocell required
Proper preparation of power supply and correct master/slave wiring, along with suitable photocell selection, are essential for reliable and safe Chain system performance.
