4.3.
TIMER - MODES OF OPERATION
Permitted by the SrEG parameter from the Hidden System Parameters section.
The timer section can work independently of the rest of the controller (from the
measured value) by starting / stopping with buttons or on the pulse front at the "Start timer"
input
or it works depending on the measured value as the timer starts when the assigned
value is reached(selected by the
SrEG
parameter).
●
MODE 1 - The timer works independently of the controller
Starting from digital input Start timer / start on front /
A button is used to manually start.
MODE 1.1:
The timer is started by activating the GND level at the Start timer input
( pressing an external button,for example), with which the timer output is activated and
begins to decrease the set time. The timer output is active until the time has elapsed or the
external button is pressed again.
The red LED blinks until the time has elapsed.
MODE 1.
2 :
ТThe timer is started by pressing an external button. The red LED flashes
until the set time elapses. After that, the output activates (indicated by a permanently
illuminated red LED) and remains active until pressing the external button or by a power
failure.
●
MODE 2 - The timer starts depending on whether the
measured value
(PV) has
reached the
controller
(SP)
setting
.
The Start timer input must have a
GND
-level enable.
A
switch
is used for manual permission.
MODE
2 .1:
The timer starts when the starting conditions are reached and an active
level at
Start timer
(permission from an external switch), which activates the timer output
and the set time starts to count down. The timer output is active until the time elapses or until
disabled by the external key. The red LED flashes until the time runs out. A new start is only
possible afterwards prohibition and re-authorization by the external switch.
MODE
2 . 2 :
The timer starts when the starting conditions are reached and an active
level at Start timer (permission from an external switch). The red LED flashes until the set
time elapses. After that, the output activates (indicated by a permanently illuminated red
LED) and remains active until disabled by the external key or by a power failure. A new start
is only possible afterwards prohibition and re-authorization by the external switch .
In the above two modes, when feeding the supply voltage, if enabled from the external
switch
and the startup conditions are present, the timer restarts!
