7.1.5.1 FILL OPTION 1
Option 1 (default):
This option is for setups using 3 solenoids to control flow from low/mid/high banks. The solenoids are
connected as follows:
If all three lines are not being used, remove solenoid connections, starting from the highest
bank.
At the start of the fill, both the low bank valve and the high bank valve are opened. After flow starts and
the optional
pfs
initialization (see section 8.3, page 34) is complete, flow is continued through the low
bank valve. The flow is allowed to stabilize for ¼ second and then the flow is measured over the next
¼ second. If this flow is below MIN. FLOW (m500 setting) , then the mid bank valve is opened
immediately. Otherwise sequencing continues comparing the flow rate with IPTP1 (Increase Pressure
Trip Point 1) to determine when to open the mid bank valve (see Figure 17, next page). When the mid
bank valve has been opened, the flow is again allowed to stabilize for ¼ second and then flow is
measured over the next ¼ second. If the flow is less than the MIN. FLOW (m500 setting), the high
pressure valve is also opened and the sale is allowed to complete; otherwise sequencing continues
comparing the flow rate with IPTP2 (Increase Pressure Trip Point 2) to determine when to open the
high bank valve.
