3.5.13 Group 3.11: Timer functions
The functions of this parameter group can be made the fullest advantage of if the Real Time
Clock settings have been properly made during the Startup Wizard (see page 2 and page 3).
You can program the up to five incidents to take place between set points of time (Intervals)
and additionally three timer-based functions to last for a set period of time.
Intervals and Timers are assigned to the three available Time Channels .
Example of programming: You want to apply Preset frequency 1 (M3.3.11, set to use with
parameter M3.5.1.15, Preset frequency selection 0) Mondays, from 08:00 until 16:00 hrs .
1. Set the parameters for Interval 1 (3.11.1):
M3.11.1.3: From day: '1' (=Monday)
M3.11.1.1: ON time: '0800'
M3.11.1.2: OFF time: '1600'
M3.11.1.4: To day: '1' (=Monday)
M3.11.1.5: Assign to channel: '1' (= Time Channel 1)
2. Then assign the selected Time channel to a digital input using the programming
method described in chapter 3.5.2.
Go to menu Parameters (M3), further down to menu I/O config (M3.5) and Digital inputs
(M3.5.1). Locate the parameter Preset frequency selection 0 (M3.5.1.15). Change the value of
this parameter to TimeChannel.1.
Now the function Preset frequency selection 0 is activated at 08:00 on Monday and deactivated
at 16:00 the same day.
The status of the Intervals and Time channels can be monitored in Menu M2.3.
