Wait Mode
If necessary, press STEP until you see the message:
Wait Mode selects which method the system uses to determine thermal stability before performing a line leak test,
TEMP. MEAS. (temperature measurement) or VOL. CHG. MEAS. (volume change measurement).
Select TEMP. MEAS. if your system has both an in-tank probe and a ground thermistor installed, and has lines less
than 500 feet (151 m) in length.
Select VOL. CHG. MEAS. if your system does not have both in-tank probe and ground thermistor installed, or your
system has lines over 500 feet in length.
NOTE: If you are using flexible piping, you cannot use the VOL. CHG. MEAS. option.
Press STEP to accept TEMP. MEAS., or CHANGE then ENTER to select VOL. CHG. MEAS. The system
confirms your choice with the message:
Press STEP to continue.
New Blender Protocol (NBP) Partner
If necessary, press STEP until you see the message:
The NBP (New Blender Protocol) Partner feature allows LLDs attached to lines, where products are blended at
the pump using a blend valve, to continue operating if the blend valve leaks. The recommended setting is NONE.
However, if line leak failures repeatedly occur because of blend valve anomalies, choose the corresponding
blended line number (determined by the number of volumetric LLDs).
NOTE: NBP is normally used for mechanical blenders only.
To accept None for the NBP Partner, press STEP. (The system displays the LAST ANNUAL TEST PASSED
message).
To choose a pipeline for the NBP Partner, press CHANGE in response to the NBP PARTNER message. Select
the desired line and press ENTER. The system displays the message:
Press STEP to continue.
