Control functions
The new switching actuators provide automation of lighting or control
of motors. These control functions are available for that purpose:
• Switching input: control input for ON respectively OFF commands
• Control value input: A control value input with configurable
thresholds for On and Off switching can be used as an alternative
to a switching input. The control value input is a control input for an
analog control value e.g. temperature, percent value, power, illumi-
nance and integer numbers. The control value input is transformed
via an upper and a lower threshold into an ON respectively an OFF
command.
• Alternatively available operating types:
- Normal operation
- Timer operation
- Flashing operation
• Logic operations (AND, OR, NAND, XOR, NOR, FILTER, TRIGGER)
• Central switching
• 8-bit scene control
• day / night operation
Each output of the actuator can be individually set to one of these
operating modes:
• Normal operation
• Timer operation
• Flashing operation
In the operation mode „normal operation“ the timer functions for
delayed On and Off switching and timer night mode operation are
available.
In the operation mode „timer operation“ the functions timer day ope-
ration and timer night operation are available. In the operation mode
„Flashing“ the output is cyclically turned on and off with configurable
on and off duty cycles. In timer day or night operation switching On of
the output can be time limited (e.g. for cleaning lighting), if applicable
with warning before switching off via off and on switching of the
output (single flashing).
Per output there is an integrated 8-bit scene control with each output
assignable to up to 8 scenes.
Override control functions
To realize special functions which have a higher priority than standard
control functions. Up to six different override function blocks plus
forced control can be activated to override the control functions.
Per actuator output up to six different override functions (1 to 6) can
be freely selected. The override control function 6 has the highest
priority, the override function 1 the lowest. With the switching actu-
ators the forced control function always has second highest priority
between the override functions with priority 5 and 6. For each one of
the activated override functions one of the following functions can be
chosen:
• Manual override ON
• Permanent OFF
• Blocking function
• Central override
• User-defined override function
• Forced control
This allows to flexibly configure a different priority dependent overri-
de for each actuator output. For the override functions a control valve
input can be selected instead of a switching control input. Override
functions can be used to address special cases in room and building
control like fire alarm, evacuation or maintenance work.
For instance, in case of a fire by switching off loads the ignition res-
pectively support energy for the fire is removed. In case of evacuation
the evacuation route lighting can be force controlled switched on. To
avoid person and property damage during maintenance work an
output can be switched off and switching on of the output can be
blocked during maintenance.
