OPERATION
The indicator front panel, and its parts, can be viewed in Fig. 12:
Fig. 12 – Identification of front panel parts
The indicator has the following parts:
Upper Display / Programming: Shows the intended value (set on
Ma1n
screen of Function Cycle). At the time of setup, it shows the
mnemonics for the different parameters that should be defined.
Lower Display / Parameters: Shows the intended value (set on
Ma1n
screen of Function Cycle). At the time of setup, it shows the
values established for the several parameters.
Rx and Tx Indicators: They show activity in the RS485
communication line.
A1, A2, A3 and A4 Indicators: They show the alarms that are on.
Key: “Function” key, whose operation is user selectable.
Key: This key has two functions. When you press it quickly,
you are taken to the next screen. When you press and hold for more
than 3 seconds, you will be taken to the next cycle and subsequently
on if you keep holding.
Up
and Down
keys: They allow changing the parameter
values. They are also used for viewing the memorized maximum and
minimum values.
Key: Return key. When you press it quickly, you are taken to
the previous screen. If you press and hold for more than 3 seconds
outside the main cycle, you will be taken back to the main cycle. If
you hold this key for more than 10 seconds inside the main cycle,
the 8-digit serial number will be shown on both displays.

SPECIAL KEYBOARD FUNCTIONS
There are several screens whose values are the “floating point” type,
that is, they take a varying number of decimal places. In such cases,
special combinations of keys may be used to edit values.
The special function is activated by pressing
, therefore you
have 3 seconds to use it with any other key, otherwise the original
.
In order to increase the number of decimal places, quickly press
while holding
. The number of decimal places will be
reduced if you quickly press
while holding
.
When the operating element of the screen is the floating point type, it
is also possible to choose which digit will be increased or decreased.
In order to choose the digit, quickly press
while holding
.
Selection of the digit occurs from right to left and the chosen digit will
blink fast.
There is an exception to the main screen. Instead of parameters, this
screen shows values for the inputs. These values are shown as
floating points in both displays. In this case, it is possible to set the
number of decimal places in the lower display by quickly pressing
while holding
. In order to set the number of decimal
places in the upper display, quickly press
while holding
.
