Switch Test Option
6.12 Switch Test Option
This function automates the testing of pressure switch devices. Connect the pressure port of the
switch to be tested to the output port. Connect the switch contacts in series with the 24
V dc
output and the Logic input.
Figure 6-2: Example Switch Test Connections
Note: The volt-free logic input connections require a switching potential (24 V max) to be applied.
If necessary, this can be an external DC source. Common mode must be kept within 30
V
maximum.
