INTRODUCTION
The LoopView indicator measures the electrical current circulating in
a current loop and displays values proportional to the measured
current. It obtains the electrical energy necessary for its operation
from the electrical current circulating in the control loop, without
affecting the value of this current.
LoopView is suitable to receive in its female connector 2-wire type
transmitters (sink) whose connection is in DIN EN 175301-803 A
standard.
The relationship between the measured current value and the
respective value shown in the display is established by defining the
Indication Range. For the definition of the indication range, the
values to be shown in the display must be entered for the current
value 4 mA (
IN.ll
) and the current value 20 mA (
IN.Kl
).
PRESENTATION
The indicator frontal panel can be seen in Figure 01:
Figure 01 – Overview of LoopView
Display: It shows the measured variable, the configuration
parameters and its respective values and conditions.
and Navigation Keys: It allows you to change the
parameters values and access the configuration cycles and
calibration of the indicator.
FUNCTIONAL FEATURES
LoopView has the following functional features:
•Adjustable indication range;
•Increasing or decreasing indication;
•Adjustable decimal point;
•Adjustable Offset;
•Adjustable digital filter;
•Display alarms: minimum value, maximum value or out of range
values;
•Factory calibration repair;
•Configuration protection with password.
OPERATION
By simultaneously pressing the keys + simultaneously,
several configuration parameters will be displayed sequentially. The
keys must be released in the desired parameter.
When you release the keys in the desired parameter, it will be
displayed. Its current value is also displayed.
The + keys allow to make desired changes in current
value of the parameter. To save the new set value, simply press the
+ keys simultaneously, returning to sequential display of
the configuration parameters.
STARTUP
LoopView must be installed in a previously validated process loop
with a power supply and a properly operating 4-20 mA transmitter in
order to establish an electrical current proportional to the measured
variable (PV): temperature, pressure, flow rate, etc.
Under the above conditions, when the power supply is turned on,
LoopView will display a value proportional to the measured electrical
current and according to the current configuration. If necessary, a
new configuration must be made at this time, align with process
characteristics.
The configuration consists of setting appropriate values for the
several parameters of the indicator that together determine its
operation mode. The parameters are displayed in the same order as
the indicator.
CONFIGURATION PARAMETERS
dp.po
Decimal Point.
It allows you to determine the position of the
decimal point the indication range configuration.
IN.ll
Lower limit of the indication range.
It allows you to determine the value set for the
display corresponding to the current value 4 mA.
IN.Kl

It allows you to determine the value set for the
display corresponding to the current value 20 mA.

Function that allows changes or corrections to the
PV value displayed by the indicator.
Filt
Filter
.
Parameter that defines the value of the filter
applied to the signal processing. Used to improve
the stability of the measured signal.
Configurable with values between 0 and 9 (Value
in seconds of the filter 1).
FvaL
Alarm Function.
LoopView has the ALARM function to indicate
that process critical PV values have been reached.
When a PV value defined as critical is measured
by the indicator, the d
isplay interpolates the
presentation of PV value with
AL
message.
The PV value critical to the process is set in
SPAL
parameter.
Three alarm functions are available:
LO
The display should indicate that the PV
value is BELOW the critical value that
has been set (
spaL
).
KI
The display should indicate that the PV
value is ABOVE the critical value that
has been set (
spaL
).
IErr
The display should indicate that the PV
value is out of the defined measuring
range.
Off
Critical value indication is disabled.
spaL
Alarm Setpoint.
It allows you to set the PV value critical to the
process used for alarm indication.
This parameter will not be displayed when Alarm
Function is set to
Off
or
IErr
.

the Protection parameter.
Without the password, the configuration can only
be viewed.

It allows you to calibrate the indicator, showing the
necessary parameters for the procedure

Do not retrieve the last calibration.
yes
YES, retrieve the last calibration.
pas.(
Setting a new access password.
It allows you to set a new access password,
always different from zero.

It allows you to set the level of protection to be
adopted by the indicator.

CONFIGURATION PROTECTION
The indicator allows the protection of the configuration created by the
user, preventing improper changes in the values of the configuration
parameters.
You can always view the parameters. To make changes, you must
enter the password in the
PASS
parameter. You can change the
parameters if the password is correct. You cannot make changes if
the password is not correct.
LoopView allows two different levels of protection: Protection for all
configuration parameters or protection for a special group of
parameters, defined as Special Configuration Parameters. These
parameters are always protected because they are relevant to the
operation of the indicator.

Table 02 – Configuration protection levels
ACCESS PASSWORD
When accessed, the protected cycles require the Access Password.
If entered correctly, the password will allow changes to be made to
the configuration of the parameters of these cycles.
The access password must be entered in the Access Password
(
PASS
) parameter, shown in the first of the protected cycles. Without
the access password, the parameters of the protected cycles can
only be viewed.
The indicator leave factory with the access password set to
1111.
MASTER PASSWORD
The Master Password is intended for allowing the user to define a
new password in the event of it being forgotten. The Master
Password doesn’t grant access to all parameters, only to the
Password Change parameter (
PAS.(
). It enables you to set a new
password for the indicator.
The master password is made up by the last three digits of the serial
number of the controller added to the number 9000.
As an example, for the equipment with serial number 07154321, the
master password is 9 3 2 1.
The serial number of the indicator is available in the
sn.x
and
sn.l
parameters.
ELECTRICAL CONNECTIONS
The indicator has standard EN 175301-803 (formerly DIN 43650) male and female connectors, located at the top and bottom of the device. It is also
has internal protection against inversion of the polarity of the supply voltage.
Figure 02 shows the required connections:

RECOMMENDATIONS FOR THE INSTALLATION
Installation, operation, and maintenance must only be carried out by
qualified personnel and in accordance with the information provided
in this manual. Any deviation from these instructions will be the sole
responsibility of the client.
Normal safety precautions should be taken to avoid the possibility of
an accident occurring when operating under high pressure and/or
high temperature conditions.
Do not connect the power supply until the entire installation is
complete.
CALIBRATION
The indicator leaves the factory calibrated and ready for use.
Recalibration is a procedure that is not recommended for
inexperienced operators.
You should consider using the recovery feature of the last performed
calibration (
rstr
). If no other calibration has been performed, the
factory calibration is still available.
If the calibration is actually required, you should proceed as follows:
1. Provide a power generator with accuracy compatible with the
measurement accuracy specification of the indicator.
2. Connect the generator to the indicator according to Figure 03:
Figure 03 – Power generator
3. Set a current of 12 mA in the power generator.
4. Set a value for the
inLL
parameter (the value must be lower
than the defined value set for
nxL
).
5. Enter the correct password.
6. Change the
Prot
parameter to
2
and thus allow changes in all
configuration parameters.
7. Change the
(alib
parameter to
YES
and thus enable the
calibration and its parameters.
8. Access the
INL(
parameter.
9. Set a current of 4 mA in the power generator.
10. Set the value of parameter
INL(
so that it reads -1999.
11. Access the
INx(
parameter.
12. Set a current of 20 mA in the power generator.
13. Set the value of
INx(
parameter so that it indicates 9999.
14. Validate the calibration mode.
