5.2 Mains power connection
Connect the 230V AC supply to the controller using a flexible cable (2 core + earth) of suitable cross
section to the L, E and N terminals as shown. This cable should be capable of carrying the actuator load
current up to a maximum of 6A @ 230V AC
5.3 Actuator Connections
Two terminal blocks are supplied for the connection of actuators to the controller. If connecting to more than
two actuators, then external junction boxes will be required.
Connection to the actuators is made using 3 core + earth cable of suitable cross-section to carry the
maximum actuator current.
In operation, the actuator power is timed off automatically after a period defined for the mode of
operation. For Caretaker, Rain and Thermostat demands this period is 180 seconds (Factory adjustable).
For day to day and 0-10V demands the default period is 18 seconds (Factory adjustable).
The default actuator output mode is for motor open/motor close actuators. Other devices (such as
magnetic catches) can be selected at the factory by S E Controls.
