Chapter 6. Reference

6.12.2 Test

Controls pressure between two set-points and can repeat (loop). Auto-reverse can be selected.

6.12.3 End

Controls pressure to a safe condition to disconnect switch under test.

6.12.4 Procedure

Select the switch test parameters in the switch test menu, including the start pressure, end

pressure and test rate of change. Slower rates give more accurate results. The de-bounce time

can be set between 0 and 200

ms.

After the test, the display shows the pressures at which the contacts open and close and the

switch hysteresis (the difference between the two switching pressures).

Before disconnecting the switch under test, press Release pressure to release any residual

pressure.

Note: This switch test procedure can be repeated to “exercise” the switch unit.

Logic input is opto-isolated. An external supply (5V to 24 V dc) can be used provided its’ common

mode voltage remains with 30V max with respect to chassis.

6.13 Test Program Option

The test program task provides a facility for writing and executing test procedures. Selecting a

test program from the Task menu displays all the task programs currently stored, together with

the ability to write new ones.
