7. FAILSAFE
FAILSAFE is a system for checking the functionality of the photocells.
The check is always performed before the motors are started. It turns off the power supply temporarily to the photocell transmitter
and checks that this causes the contact on the receiver to open. If it does not, movement of the leaves is inhibited for safety reasons.
To enable the FAILSAFE it must be set during the programming phase.
Using the FAILSAFE requires a separate power supply for the photocell transmitter (see Figs. 26, 27, 28, 29, 30, 31)
