OPERATION
The controller’s front panel, with its parts, can be seen in the
Fig. 04.
Fig. 04
– Indicator overview
Display
: Shows the measured variable, the configuration parameters
and their values / conditions.
Decrement Key and
Increment Key
: Allow altering the
values of the parameters and accessing the indicator operation and
configuration cycles.
STARTUP
When the power is on, the indicator shows the value of the measured
process variable
(PV)
. This is the
Indication Screen
.
In order for the indicator to operate properly, its parameters need to
be configured first. The configuration consists of the calibration and
definition of the programmable interval. The user must be aware of
the importance of each parameter and for each one determine a valid
condition.
The 2 cycles of parameters are:
•
Operation
•
Configuration
When pressing both keys (
and
) at the same time, the
indicator shows a screen where the device password must be
entered. After entering the password, the indicator will show the
configuration cycle. To advance the parameters of this cycle, use the
key with short touches. To rewind parameters, use the
key. To select the parameter, press both keys (
and
) at the
same time.
ACCESS PASSWORD
On the login screen, “
0000
” will show on the display, to enter a
value, press the
, key, to change decimal places, press the
key, and to confirm the password, press both keys (
and
) at
the same time, the password is requested “
66
”.
PARAMETERS
OPERATION CYCLE
PV
PV Indication Screen
. Value of measured variable.
CONFIGURATION CYCLE
Ad-L
AD-L
Statement of the minimum calibration signal at the
beginning of the range applied to the input (Low).
Ad-h
AD-H
Statement of the maximum calibration signal at the
end of the range applied at the input (High).
Ds-l
dS-L
Sets the lower value of the indication range (Low).
Ds-h
dS-H
Sets the upper value of the indication range (High).
-Dp-
dP
Sets the number of decimal places that will be shown
on the display.
Line
Line
Parameter that allows the user to make corrections to
the indicated PV value.
Filt
Filter
Digital Input Filter - Used to improve measured signal
(PV) stability. Adjustable between 0 and 9. At 0, it
means minimum filter and at 9, maximum filter. The
larger the filter, the slower the measured value
response.

Final parameter that, when pressing both keys (
and
)
at the same time, save the settings that
have been set by the user.
CALIBRATION
Following is the
LoopView
calibration procedure, which can be
divided into two steps, the
unlocking
and the
calibration
steps:
Unlock:
1.
Connect
LoopView
into a 4-20 mA signal simulator. Vary it and
check if the indicator is powered up accordingly between 4 and
20 mA.
2.
Press
and
keys simultaneously (from now on referred
to as
/
) for 3 seconds and release them. Then
parameter
Lccy
will be displayed. It means we’ve accessed
Configuration Cycle.
3.
At
Lccy
parameter click
/
in order to enter this
parameter’s adjustment. The current displayed value will be
0000
. The
key increments values from
0
to
9
in a single
digit. The
key shifts to the next digit to be adjusted. Define
value
0066
at it and press
/
to confirm.
Calibration:
4.
Parameter
AD-L
will be displayed. Click
/
to enter this
parameter. A random number is displayed.
5.
Simulate 4 mA in its input.
6.
Single click
key. At this moment
LoopView
reads input’s
current and determines it as its lower point (4 mA). Press
/
to confirm and go back to
AD-L
.
7.
Press
key to shift to the next parameter,
AD-k
.
8.
Press
/
to enter
AD-k
. A random number will be
displayed.
9.
Simulate 20 mA in its input.
10.
Click
key. At this moment
LoopView
reads input’s current
and determines it as its superior point (20 mA). Press
/
to confirm and go back to
AD-k
. Calibration is finished
here.
11.
Press
key until parameter
END
be displayed.
12.
Press
/
to leave Configuration Cycle.
