Sequencing Rate
Only available on CNG dispensers. Needs appropriate
software.
The sequencing rate (SE9) enables you to set the percentage level of
maximum flow that sequencing occurs to the next pressure bank.
There are three settings to choose from:
 FAS: Switching to the next higher-pressure bank occurs at 40% of the
maximum flow rate for a particular bank.
 nOr: Switching to the next higher-pressure bank occurs at 30% of the
maximum flow rate for a particular bank.
 SLO: Switching to the next higher-pressure bank occurs at 20% of the
maximum flow rate for a particular bank.
From software version HIA29.25.3CNG onwards the
sequencing rates are as follows:
 FAS: Switching to the next higher-pressure bank occurs at 60% of the
maximum flow rate for a particular bank or when the flow rate drops to
5 kg/min, whichever occurs first.
 nOr: Switching to the next higher-pressure bank occurs at 40% of the
maximum flow rate for a particular bank or when the flow rate drops to
3 kg/min, whichever occurs first.
 SLO: Switching to the next higher-pressure bank occurs at 20% of the
maximum flow rate for a particular bank or when the flow rate drops to
1 kg/min, whichever occurs first.
The dispenser leaves the factory with the FAS setting.
To set the sequencing rate
1. Make sure that the dispenser is idle, with the nozzle in its holster.
2. Press and release the Parameter switch (17 or more times) until SE9
xxx is displayed.
3. Enter the sequencing rate. Each press of the Parameter switch passes
you over a digit in the setting, making the digit blink. Holding the switch
down for more than a second changes whichever digit is currently
displayed. If you want to pass over a setting without changing any
digits, keep pressing and releasing the switch.
4. The displayed sequencing rate is now selected and operation of the
dispenser will be affected immediately. The displays will reset after a
ten (10) second timeout.
