3.21 Main Menu - Time-based Functions - Group 23

3.21.1 23-0* Timed Actions
3 3
Use Timed Actions for actions needing to be performed on
a daily or weekly basis, e.g., different references for
working hours / non-working hours. Up to 10 Timed
Actions can be programmed in the Adjustable frequency
drive. The Timed Action number is selected from the list
when entering parameter group 23-0* from the LCP.
23-00 ON Time – 23-04 Occurrence then refer to the
selected Timed Action number. Each Timed Action is
divided into an ON time and an OFF time, in which two
different actions may be performed.
The clock control (parameter group 0-7* Clock Settings) of
Timed Actions can be overridden from Timed Actions Auto
(Clock Controlled) to Timed Actions Disabled, Constant OFF
Actions or Constant ON Actions either in 23-08 Timed
Actions Mode or with commands applied to the digital
inputs ([68] Timed Actions Disabled, [69] Constant OFF
Actions or [70] Constant ON Actions, in parameter group
5-1* Digital Inputs.
Display lines 2 and 3 in the LCP show the status for Timed
Actions mode (0-23 Display Line 2 Large and 0-24 Display
Line 3 Large, setting [1643] Timed Actions Status).
NOTE!
A change in mode via the digital inputs can only take
place if 23-08 Timed Actions Mode is set for [0] Times
Actions Auto.
If commands are applied simultaneously to the digital
inputs for Constant OFF and Constant ON, Timed Actions
mode will change to Timed Actions Auto and the two
commands will be disregarded.
If 0-70 Date and Time is not set or the Adjustable frequency
drive is set to HAND or OFF mode (e.g., via the LCP), the
Timed Actions mode will be change to Timed Actions
Disabled.
The Timed Actions have a higher priority than the same
actions/commands activated by the digital inputs or the
Smart Logic Controller.
The actions programmed in Timed Actions are merged
with corresponding actions from digital inputs, control
word via bus and Smart Logic Controller, according to
merge rules set up in parameter group 8-5*, Digital/Bus.
NOTE!
The clock (parameter group 0-7*) must be correctly
programmed for Timed Actions to function correctly.
