VEGA VEGAFLEX series 60 Recurring function test - Manual (Page 9)

3 .2 Verification of the current output
In this test point you simulate certain level values via the current
output. With this you can test the reaction of the sensor with different
current output values and the switching behaviour.
Warning:
The recurring function test influences connected devices. Take note
that downstream devices may be activated during the test.
1 Select in the DTM under the menu "Service" the menu item
"S
imulation".
2 Select "Current" as measured variable for the simulation.
3 Activate the simulation.
4 Set the simulation value to 4 mA.
Take note that downstream devices may be activated.
5 Accept the simulation value.
Wait approx. 30 s.
The simulation is running and a corresponding current is being
outputted.
6 Note the displayed value (4 mA simulation) of the mA-meter.
The value must correspond with the simulated value within the
safety accuracy of 2 % (±0.32 mA).
Continue with the simulation if the two values correspond.
1 Set the simulation value of the current simulation to 20 mA.
Take note that downstream devices may be activated.
2 Accept the simulation value.
Wait approx. 30 s.
The simulation is running and a corresponding current is being
outputted.
3 Note the displayed value (20 mA simulation) of the mA-meter.
The value must correspond with the simulated value within the
safety accuracy of 2 % (±0.32 mA).
The verification of the current output was successful if the two values
correspond.
Caution:
Deactivate the simulation.
Continue with the next test point.
Simulation 4 mA
Simulation 20 mA
