PRESSURE PROBES S1 AND S2
By setting the type of pressure probe S1 for driver A and S2 for
driver B, the measuring range and alarm range are defined based
on the construction data of each model and generally indicated on
the card placed in the probe.
Parameter
Description
S1
NTC temperature sensor
S2
Suction pressure transducer from 0 to 45 bar
NOTE:
If two pressure probes S1 and S2 are installed, they
must be of the same type.
It is not possible to use
one proportional and one electronic probe.
NOTE: In the case of ducted systems where the same
pressure probe is shared between twin1 and twin2
controllers, choose the normal option for driver A
of the twin1 controller and the “remote” option for
the other drivers.
Example: If you want to use for driver A and B the same pressure
probe P1, type: 4...20mA, -0,5...7 barg
For driver A of twin 1 controller select: 4...20mA, -0.5...7 barg.
For driver B of twin 1 controller and for driver A and B of twin 2
controller select: remote 4...20mA, -0.5...7 barg.
NOTES:
•
The default measurement range is always in bar gauge
(barg). In the Manufacturer menu, you can customize the
parameters corresponding to the measuring range and
alarms if the probe used is not in the standard list. If the
measuring range is modified, the driver will detect the
modification and indicate the probe type S1 and S3 as
“Custom”;
•
The driver software takes the unit of measurement into
account. If a measuring range is selected and then the
unit of measurement is changed (from bar to psi), the
driver automatically updates the measuring range limits
and alarm limits. By default, the main control probes S2
and S4 are set to “NTC CAREL”. Other probe types can
be selected in the service menu.
•
Unlike the pressure probes, the temperature probes
do not have any parameters corresponding to the
measuring range that can be changed, and therefore
only the models listed can be used (see the chapter on
“Functions” and the parameter list). In any case, in the
manufacturer’s programming mode, you can customize
the probe alarm signal limits.
MAIN CONTROL
When setting the main control, the operating mode of each driver
is defined.
Parameter/description
Predet.
1= channeled counter/chamber
Counter/channeled camera
The superheat set point and all the parameters relative to PID
control, the operation of the protectors and the meaning and use
of probes S1/S3 and S2/S4 will be automatically set to the values
recommended by CAREL according to the selected application.
During this initial configuration phase, only the superheat control
modes from 1 to 10 can be set, which differ according to the
application (chiller, refrigerated counter, etc ).
In case of errors in the initial settings, these parameters can be
accessed later and changed in the service or manufacturer menu.
If the default controller parameters are reset, the display will show
the guided start-up procedure again at the next start-up.
CHECKS AFTER INITIAL START-UP
After the first start-up:
• Check that the valve performs a complete closing cycle for
alignment.
• Set, if necessary, in the Assistance or Manufacturer
programming mode, the overheating set point (if you do not
want to maintain the one recommended by CAREL depending
on the application) and the protection thresholds (LOP, MOP,
etc ).
STEPS FOR PARAMETER SETTING AND
SEPOINT SUPER HEAT.
As mentioned in the display programming mode section, enter the
regulation menu.
By pressing the
down
key, scroll the regulation menu to number 1.
Press
enter
and use the
up
and
down
keys to select the desired
super heat setpoint, then press the
enter
key and then the
esc
key
to return to the menu selection.
