Behaviour on locking
Defines the behaviour of the locking function.
•
no action
die Schaltuhr wird nur gesperrt
•
fix value (one time)
the time switch is blocked and a fixed value is sent once upon activation
•
fix value (cyclic)
the time switch is blocked and a fixed value is transmitted cyclically
The cycle time is set by means of a common parameter for
"lock / enable" and " holidays"
Value for lock:
The value to be sent depends on the selected function. For example, only ON or OFF can be sent for
"Switching". With "Dimming", ON/OFF or a fixed value of 0% - 100% can be sent. A 1 bit value would
be transmitted via the 1 bit output object, e.g. object 0 (for function 1) "Dimming ON/OFF", but an
absolute value would be transmitted via object 2 "Dimming absolute ( only for time switch).

Table 147: Communication object: Time switch - locking object
The status output can be controlled via the flags of the lock object:
•
- By default, the K flag and the S flag are set -> The object can only be described.
•
- If the L flag is also set, the internal lock status can also be read.
•
- If the L flag and the Ü flag are also set, the object sends its internal lock status active. It
should be noted, however, that if several lock objects are located in a group address, all locks
are also set when a lock object sends its status!
When the lock object is read/sent, the internal lock status is output. Both the lock function and the
leave function can set this status.
A locked time switch is displayed in red on the device!
