Pixsys DRR244 - Retransmission Function on Analogue Output; Timer Functions

User manual - DRR244 - 19
7.13 Retransmission function on analogue output
If not used as command, the analogue output can be used to retransmit process/ setpoint/ current
read by the C.T. input/ output percentage.
Select on parameter 298
r t M .1 (“Retransmission 1”) the value to be retransmitted and on parameter 299
r.1 . t Y . (“Retransmission 1 Type”) the output type.
It is possible also to select on parameters 300
r.1.L.L. and 301 r.1 . u . L. the input value rescale limites.
7.14 Timer functions
The DRR244 integrates two timers that can be independent, sequential or looped together.
Timer 1 is enabled on parameter 328
t m r.1 . ; timer 2 on parameter 331 t m r. 2.:
EN A B. the timer starts from the keyboard or digital input (user intervention is required)
EN.StA. the timer starts counting when the regulator is in RUN.
The timer time-base set in
mm.ss or hh.mm by changing parameters 329 t.b.t.1 for timer 1 and 332 t. b. t.2
for timer 2.
In parameter 334
tM r.S. can be define whether the timers should be independent or related to each
other.
Sin G L. The timers work independently of each other.
S e Q u e. When timer 1 ends, timer 2 starts. The sequence is active only by starting timer 1. When
timer 2 expires, the sequence is interrupted.
LooP When a timer ends, another starts: the sequence repeats itself cyclically.
To change the duration of the counting time, follow the steps below:
Press Display Do
1
SET
Press until
ti mE 1 or ti m e 2 visualized on
display 1.


Digits on display 1 changes.
Increase or decrease time value for the
selected timer.
To start the keyboard count follow the steps below:
Press Display Do
1
FNC
Press until
ti m e 1 or ti m e 2 visualized on
display 2. Display 1 shows STOP if the
timer is stopped, otherwise it shows the
remaining time.
2
SET
The timer stops if active or starts counting
if in STOP.
Start/Stop of Timer is possibile also by digital input (see parameters
d . i .1 . F ... d .i .4 . F. .)
The alarm outputs can be associated with the timers (parameters
A L .1 . F .... A L. 5. F.). On parameters 330
A. tM.1 and 333 A. tM.2 is possible to select the activation mode. The proposed solutions are as follows:
Start Alarm active during timer counting
End Alarm active when the timer expiry
W A rn. Alarm active 5 “ before the timer expiry
