High Water Alarm
Set this value at a level lower than the Pump Pickup value for the submersible Pump or suction Line (See
Figure 1).
When Console detects that the Water level in the Tank is higher than the High Water Alarm value an
Alarm is posted.
Water Alarm Filter Level
The Console can be configured to provide water Alarm filtering during Deliveries. Filtering may be
required because turbulence in a Tank during Delivery may cause false Water Alarms. On a per Tank
basis, the user is able to select the level of filtering; Low, Medium or High. The default filter setting of Low
will provide the quickest Alarm response time, but may be susceptible to false Alarms. In most
applications the Water Alarm Filter Level setting of Low will not produce false water Alarms.
Adjustments to the Delivery fill tube may eliminate false water Alarms caused by Delivery turbulence. If
Deliveries are causing an unacceptable number of false water Alarms increase the Water Alarm Filter
Level to Medium. If the false water Alarms continue increase the filter level to High.
The three filter levels are explained in more detail below.
LOW FILTER
When the Water Alarm Filter is set to Low Deliveries will not inhibit the posting of Water Alarms.
With the Low setting the Console detects that a Delivery is occurring when the fuel level in the Tank
increases by 25 Gallons per Minute (GPM).
Low Filter - High Water Alarm
During a Delivery if the Console detects a High Water Alarm condition for three minutes it posts both an
High Water Alarm and a High Water Warning immediately. The Delivery may still be in-progress when the
Alarm and Warning occurs.
During a Delivery if the Water level is less than the High Water Alarm value the Console will clear the
Alarm.
Low Filter - High Water Warning
During a Delivery if the Console detects a High Water Warning condition for three minutes, but does not
detect a High Water Alarm condition during this time, the Console posts a High Water Warning after the
Delivery is complete.
If the Delivery is in progress for more than 60 minutes, the High Water Warning posts after 63 minutes
from the start of Delivery detection.
The same logic applies to the clearing of the High Water Warning.
Low Filter - Maximum Height for the No-Delay Condition
If the Water level is six inches or above the High Water Alarm value for three minutes, then the Console
posts a High Water Alarm and High Water Warning, even when a Delivery is in progress.
