6. ConFigurAtion proCedure
6.1 introduCtion
When the instrument is powered, it starts immediately to work
according to the parameters values loaded in its memory.
The instrument behaviour and its performance are controlled
by the value of the stored parameters.
At the first start up the instrument will use a “default”
parameter set (factory parameter set); this set is a generic
one (e.g. a TC J input is programmed).
wArning! before connecting the output actuators
,
we recommend to configure the parameters to
suit your application (e.g.: input type, Control
strategy, alarms, etc.).
wArning!
Do not change the
[5] unit (engineering unit)
value during process control as the set point
inserted by the user (thresholds, limits etc.) are
not automatically rescaled by the instrument.
To change these parameters you need to enter the
“Configuration mode”.
6.2 instrument behAviour At
power on
At power ON the instrument can start in one of the following
mode depending on its configuration:
Auto mode
.
–
The upper display will show the measured value;
–
The middle display will show the Set point value;
–
The lower display will show the valve position (measured
or theoretical according to the control strategy selected).
–
The instrument is performing the standard PID control with
servo-motor drive output.
Manual mode
(oPLo).
–
The upper display shows the measured value;
–
The middle display shows the power output [preceded by
H
(for heating) or
C
(for cooling)]. The MAN LED is lit;
–
The lower display will show the valve position (measured
or theoretical according to the selected control).
–
The instrument does not perform Automatic control;
–
The control output can be manually modified by
and
buttons.
Stand by mode
(St.bY).
–
The upper display will show the measured value;
–
The middle display will show alternately the set point value
and the message
St.bY
or
od
;
–
The lower display will show the valve position (measured
or theoretical according to the control strategy selected).
–
The instrument perform no control at all
(Out 2 [close] is always ON);
–
The instrument is working as an indicator.
We define all the above described conditions as
“
standard display
”.
6.3 entering in the
“ConFigurAtion modes”
The configuration mode allows to take advantage of all
instrument features.
The instrument have one complete parameter set indicated as
“
Configuration parameter set
” (or “
Configuration parameters
”)
The access to the configuration parameters is protected by a
password.
note:
The instrument shows only those parameters that are
consistent with the hardware and in accordance with the
value assigned to the previous parameters (e.g.: if you
set an Alarm as “not used”, the instrument masks all the
remaining parameters related to this Alarm).
6.3.1 Complete configuration procedure
The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (e.g.: control, alarms, output functions).
1.
Push the
button for more than 5 seconds. The upper
display will show
PASS
while the middle display shows
0
.
2.
Using
and
buttons set the programmed password.
notes: 1.
The factory default password for configuration
parameters is equal to
30
.
2.
During parameter modification the instrument
continue to perform the control.
In certain conditions, when a configuration
change can produce a heavy bump to the
process, it is advisable to temporarily stop the
control during programming procedure.
When it is desired to stop the control during
progrmming procedure, use a password equal to
2000 + the programmed value (2000 + 30 = 2030).
The control restarts automatically when the
configuration procedure will be manually closed.
3.
Push the
button.
If the password is correct the display shows the acronym of
the first parameter group preceded by the symbol:
]
.
In other words the upper display shows:
]inp
(group of the
input parameters
).
The instrument is in configuration mode.
4.
If the password is not correct, the instrument returns to
the Standard Display.
6.4 leAving the “ConFigurAtion mode”
Pushing the
button for more than 5 seconds, the
instrument returns to the “Standard display”.
6.5 KeyboArd FunCtions during
pArAmeter ChAnging
A short press allows to exit from the current parameter
group and select a new parameter group.
A long press allows you to close the configuration
parameter procedure (the instrument will come back
to the “standard display”).
When the upper display is showing a group and the
middle display is blank, this key allows to enter in the
selected group.
When the upper display is showing a parameter and
the middle display is showing its value, this key allows
to store the selected value for the current parameter
