Switch Test
Note:
Result files are stored within the internal memory of the DPI 610E. See Chapter 14 (File
System). Only the list of test result files can be viewed on the device. Details of the files can only
be accessed when the files are opened on a PC (See Section 9.6.2 on page 169).
Step 7 Close the pressure line by fully closing the pressure release knob. Check there are no leaks.
Step 8
Slowly start to pressurize the system. If
the trip or actuation point is known and
it is safe to do so, the pump may be
used to quickly ramp up the pressure
close to the setpoint and then the
volume adjuster can be used to slowly
increase the pressure closer to the
setpoint.
Once the switch is actuated, the
actuation pressure is recorded in the
switch test channel window. The state
icon for the actuation is also displayed
i.e. icon of a switch open or a switch
closed.
Increase the pressure a little more and
allow to settle.
Gradually start to reduce the pressure
using the volume adjuster. At the switch
reset (De-actuation) point, the pressure
is recorded and the switch state icon at
this point is displayed.
The test is concluded with the
Hysteresis value calculated and
displayed. This completes the switch
test cycle.
If required, the test result can be saved
by selecting the
Save
softkey
before exiting the test screen.
A keypad appears on the screen. Use
this keypad is you want to enter a new
name for the results file.
If the results are saved, the test details
will be cleared and the test will be
restarted.
If the results are not saved, a new
switch test cycle can be set up ready to
be run. To do this, carefully vent the
system (open the pressure release
knob) and then select the
Restart
softkey.
