6.3 CONFIGURING THE ANALOG OUTPUT (EXAMPLE)
The analog output can be configured in the menus ZP (zero point) and EP (end point). The following example shows how to use them:
In this example, the device has a measurement range of 0–6 bar (0–87 psi), and it is connected to P1. The analogous signal amounts to 4…20 mA / 3-wire and were
configured in the menu 26 “SiAn” on “P1.”
The output analog signal:
0 bar (0 psi) = 4.00 mA
3 bar (43.5 psi) = 12.00 mA 6 bar (87 psi) = 20 mA.
If the value is changed from 0 to 1 in ZP and the EP value from 6 to 5 , the output signal changes as follows:
1 bar (14.5 psi) = 4.00 mA
3 bar (43.5 psi) = 12.00 mA 5 bar (72.51) = 20 mA.
The values of ZP and EP are adjustable up to 1:10 of the nominal pressure range.
6.4 HYSTERESIS AND COMPARE MODES
The diagrams below show the operation of the switch outputs.
To reverse the relevant modes, you have to swap the values for the switch-on and switch-off points.
