To edit weight thresholds for both setpoints:
1.
Press
TARE
( ) on the front panel, and keep it pressed for around three seconds.
The display shows
Fn 00
. The left zero flashes.
2. Editing setpoints is function 01, so press
t
(
TARE
) to move to the second digit. It
starts flashing.
3. Press
u
(
P.TARE
) once. The display should now show
Fn 01
.
4.
Press
( ) to confirm. The display shows
SEtP 1
briefly. Then it shows the
current threshold for setpoint 1. The extreme-left digit flashes.
If you don’t want to change this threshold, press
( ) and skip to step
6.
If you do want to change it, proceed to step 5.
5. Enter a new threshold value. To do this, press
u
(
P.TARE
) to change the current
digit, then
t
(
TARE
) to move to the next digit. To finish, press
( ).
6. The display now shows
SEtP 2
briefly, then the current threshold for setpoint 2.
The extreme-left digit flashes.
If you don’t want to change this threshold, press
( ) and skip to step
8.
If you do want to change it, proceed to step 7.
7. Enter a new threshold value. To do this, press
u
(
P.TARE
) to change the current
digit, then
t
(
TARE
) to move to the next digit. When you are done, press
( ).
8. The threshold values are saved in EEPROM memory.
7.4 Configuring Analog Output
The analog output channel allows the indicator to communicate with PLC devices,
using one of the following two methods:
Converting load cell input into voltage (0-10V).
Converting load cell input into current (0-20mA or 4-20mA).
This feature is only active if your indicator is equipped with an optional analog output
board. Section
7.4.1 below explains how to connect the analog output board, and set
a hardware jumper to define which of the two output methods to use.
After connecting the board and setting the jumper, you can set analog output
parameters using the
SETUP
>
ACAL
menu (see section
7.4.2).
