9.12 Time switch
9.12.1 Function of the timer
The device has a real time clock. The clock is backed up (Gold Cap) and has a reserve of 2 or 3 days
after suf
fi cient operation on a voltage supply.
The time and date must be set during start-up operation and when using the real-time clock. The
device calculates the weekday based on the date.
In principle, the timer function acts like a digital switch input (timer
“ On ” closed contact at inverting
OFF). The same functions can be assigned to the timer switch as the digital inputs (see IO Setup/Di-
gital inputs
“ DI ” ).
Inverting of the timer function
The timer function can be inverted by inverting the digital input to which the timer function is assigned
(see IO Setup/Digital inputs
“ DI ” ).
With inversion “ DI ” = “ OFF ” (factory setting) the programmed function is activated at the switch on time
(clock symbol in display) and deactivated again at the switch off time.
With the setting
“ DI ” = “ ON ” the programmed function is deactivated at the switch on time and
reactivated at the switch off time (clock symbol in display).
