Each channel has a toggle switch with three settings
Manual on, Auto, Manual off.
There are 2 LEDs fitted per channel:
The upper LED is two-colour and displays the operating mode for the channel:
amber = Manual; green = Automatic
The lower LED displays the switch state of the relay:
Red = relay activated.
Example (above):
Output 0:
Manual off
LED 1 = amber
Relay off
LED 2 = off
Output 1:
Manual on
LED 1 = amber
Relay on
LED 2 = red
Output 2:
Automatic
LED 1 = green
Relay off
LED 2 = off
Output 3:

LED 1 = green
Relay on
LED 2 = red
If there is no external supply to the relay coils, the LED does not light up and the
relays are not activated.
There is no error message to the Saia PCD
®
where the electrical supply is not pres-
ent.
