9.11 TIMER FUNCTIONS
The timer functions make it possible for the internal RTC (Real Time Clock) to control
functions. All the functions that can be controlled with a digital input, can also be controlled
with the RTC, with time channels 1-3. It is not necessary to have an external PLC to control a
digital input. You can program the closed and opened intervals of the input internally.
To get the best results of the timer functions, install a battery, and make the settings of the
Real Time Clock carefully in the Start-up wizard. The battery is available as an option.
NOTE!
We do not recommend that you use the timer functions without an auxiliary battery.
The time and date settings of the drive are reset at each power down, if there is no
battery for the RTC.
TIME CHANNELS
You can assign the output of the interval and/or timer functions to time channels 1-3. You can
use the time channels to control on/off type functions, for example relay outputs or digital
inputs. To configure the on/off logic of the time channels, assign intervals and/or timers to
them. A time channel can be controlled by many different intervals or timers.
