Section 5: Working Principle
Working Principle
The SOV TEST can be performed by using a dedicated input (SOLENOID B CONTROL) or a dedicated
parameter (RL B CMD).
The SOV TEST is executed only on to the SOV B.
The SOV B is not involved in the other commands of the IMVS2000v2 (Calibration, Signatures and PST),
for these commands the SOV A is used.
In this configuration:
• SOV A is used for the PST
• SOV B is just used for its own SOV TEST.
• The SOV TEST can be performed only if a Baseline PST is already successfully done.
See Errore. L'origine riferimento non è stata trovata. for details.
3. Configuration Z
• “Act. Mode” = “Single” or “Double-S”
• “SOVs Qty” = “Simplex”
• “PST Ser. SOVs” = “One”
• “Pr. S. 1-2” ≠ “None”
• “PST En.” = “No”
• “PST Pos. %” = 0.0%
• “PST Pres. %” = 0%
• “PST Time %” = 0%
• “Al. PSA En.” ≠ “No”
4. Configuration T
• “Act. Mode” = “Single” or “Double-S”
• “SOVs Qty” = “Series”
• “PST Ser. SOVs = “Both”
• “Pr. S. 1-2” ≠ “None”
• “PST En.” = “No”
• “PST Pos. %” = 0.0%
• “PST Pres. %” = 0%
• “PST Time %” = 0%
• “Al. PSA En.” ≠ “No”
• “Al. PSB En.” ≠ “No”
The SOV TEST can be performed by using a dedicated input (PST CONTROL) or the dedicated
parameters (BASELINE PST CMD or MANUAL PST CMD).
The SOV TEST is executed on both solenoid valves and it can be completed only if a Baseline Signature
is already successfully done.
