APPENDIX 1
Protection of the power line for the CS8C
controller
I. CONTROLLER CHARACTERISTICS
The CS8C controller is protected at its input from risks of short-circuits by Am type fuses.
The load on the primary circuit depends on the type of arm installed, the voltage rating of the power supply and
the type of network (single phase or three-phase) (load = current in the controller power supply circuit when the
arm is operating).
When the controller is powered on, a surge current is generated. The current reaches the level of continuous duty
after ª 8 periods, i.e. ≈ 160 ms for a 50 Hz power frequency. The first peak of the surge current is ª 20 x In.
II. PROTECTION UPSTREAM FROM THE CONTROLLER
The protections upstream from the controller are used to protect the secondary circuits of the upstream
transformer from overcurrents and short-circuits.
