level. This automatic reset of the bypass ensures the alarm is active
the next time the tank is filled. The bypass can also be manually
removed by pressing the TOTAL and SHUT DOWN buttons at
the same time. If multiple tanks are in alarm, they all must be
bypassed before the alarm is turned off.
To program the overfill warning and shutdown alarm points:
1. Using the 817 programmer, set alarm 1 for the overfill
shutdown point, alarm 2 for the overfill warning point, and
alarm 3 for the bypass removal (minimum tank level) point.
Alarm 1 must be higher than alarm 2, and alarm 2 must be
higher than alarm 3.
2. All three of the alarms must be programmed as shutdown.
3. A3 should be set a few inches above the normal minimum tank
operating level. This way tank sloshing will not inadvertently
remove the bypasses and activate an alarm, and yet ensure
that the bypasses are removed prior to filling during normal
tank operation.
