The Relay functions

Description

Relay functions modify the status of a relay between on and off. When somebody pushes a button, the connected relay is switched (the status is changed from OFF to ON or if already ON it is changed to OFF).

The functioning of an interface:

Relay
this parameter defines the relay which is being switched by this function.

Option 'Switch On/Off' (standard)

Short
with a short push the relay is being switched. In particular this means that the light switches ON when it was OFF and vice versa.
Long
with a long push the relay is being switched. In particular this means that the light switches ON when it was OFF and vice versa.

Option 'Switch On'

Short
with a short push the relay is being switched on. In particular this means that the light switches ON.
Long
with a long push the relay is being switched on.

Option 'Switch Off'

Short
with a short push the relay is being switched off. In particular this means that the light switches off.
Long
with a long push the relay is being switched off.

Behaviour when the function is used in another function

'Relay' type

When the relay is called from another function, the functioning depends on the set target value. Following possibilities can occur:

On
the relay switches ON when it was OFF and remains switched ON when it was switched ON.
Off
the relay switches OFF when it was switched ON and remains switched OFF when it was switched OFF.
On/Off
the relay switches ON or remains switched ON when activating the function and switches OFF when the function is switched OFF.
Off/Off
The relay switches OFF and remains switched OFF when the function is switched ON. If the function is switched OFF, then the relay remains switched OFF.
Not every function can be switched off. Consult for this matter the description of the respective function.

General Remarks

If the function is used from an interface or from another function, if the direction relay of a motor function is activated, then the respective motor function is being executed. Consult the description of the motor function for more information.
If several relays are being switched simultaneously, then the central unit will switch the different relays consecutively with an adjustable time delay between the two actions. This time delay is adjustable in the 'Extra' 'Options' 'Specials' 'Relays delay' menu and is set by default to 50 msec.
