Figure 18: Solenoid test with pressure sensor
Before the IDC can perform a test the system must be calibrated. The calibration consists of two
steps, an endpoint calibration and a reference.
When a test is started the position and pressure is evaluated. A test will not be started if the start
conditions are not correct. The start conditions are as follow:
• Valve must be at the operational position
• Pressure must be within the Start pressure low and Start pressure high limits. This function
can be disabled.
An error will indicate what the problem is.
The IDC monitors the position and pressure during the test. The IDC aborts the test and report an
error if the limits in the error parameters are reached.
If a test does not reach the limits it will run until finished and then the warning parameters are
evaluated.
If the system does not have a pressure sensor, all pressure related parameters, warnings and errors
will be ignored.
The errors or warnings can only be removed by performing a successful test.
