Setting Thresholds for Digital Setpoints
VT400 Technical Manual, Rev. A5 51 Doc # UM-VT400-EN
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 PRINT (
) 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 PRINT (
) and skip to step
6.
If you do want to change it, proceed to the next step.
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 PRINT (
).
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 PRINT ( ) and skip to step
8.
If you do want to change it, proceed to the next step.
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 PRINT
(
).
8. The threshold values are saved in EEPROM memory.
7.3.1 Parameters for Digital Outputs
The following parameters can be edited by accessing SETUP > SETUP 5.
Par. Description Values
5.1, 5.2 Setpoint 1 output. 5.1=0 and 5.2=0: normal
5.1=1 and 5.2=0: no motion
5.1=0 and 5.2=1: error
5.3, 5.4 Setpoint 2 output. 5.3=0 and 5.4=0: normal
5.3=1 and 5.4=0: zero
5.3=0 and 5.4=1: net
5.6 Net / gross for both setpoints. 0=net
1=gross
5.7 Normally open / closed for both setpoints. 0=normally open
1=normally closed
