SubDrive Duplex Alternator
Setting the Alternate Time
The alternate time is set by pressing the button labeled "Change Interval".
One press will move the orange indicator light over one position; each position
is labeled with a different alternate time. When the primary system has
accumulated an amount of run time equal to the selected alternate time, the
alternator will switch the primary system to the backup system and the backup
system to the primary system.
Note: Changing the alternator time will NOT reset the cumulative clock.
Fault Detection
The alternator continuously monitors the water system demand, checking to see
if the water demand is being met as expected. If the water demand is not being
met as expected, the alternator will begin looking for possible problems with the
system. While it's looking, the alternator will alternate the two drives back and
forth a few times. After performing the check, the alternator will either declare a
fault or leave the system as it was if no problem was found.
Manual Override/Clear Fault Button
The manual override button allows the user to switch which SubDrive system
is the primary system at any time. When the user presses the "Switch Pump or
Clear Fault" button, the alternator switches the primary system to the backup
system and the backup system to the primary system. When this happens, the
cumulative clock is RESET and begins counting again.
The second function of this button is to clear a fault from the alternator's
memory. If this button is held down for 5 seconds, the red FAULT light will clear
and the Alarm Relay will open.
Note: If the alternator loses power, it will not retain any faults found and will reset
the cumulative clock. The alternator will "relearn" a fault that was lost during loss
of power.
