Testing and Inspection
Testing can begin once the system is completely installed and sufficient water is in the
pump tank. Walk through the dispersal field and inspect any valve, air relief valve and
other exposed equipment and insure that each is properly aligned for automatic
operation. Switch the control and pump breaker to
OFF
. Insure that power is available
from the primary house or building breaker box. Switch the pump breaker to
ON
.
Switch the control panel 10 amp or toggle switch to
ON
. The BDMC will beep, the
pump will start and the filter will go into an immediate back flush for the next two
minutes. The ON, FILTER FLUSH and FIELD FLUSH lights should be illuminated on
the BDMC panel. Upon completion of the two-minute filter flush the FILTER FLUSH
light will go off and FIELD FLUSH light will remain on for 6 more minutes. The FIELD
FLUSH light will go off once the flush is complete. The pump may remain operating if
the dosing time is set for more than six minutes. For more details, refer to the BDMC
Manual Start-Up Operations, Field and Filter Flush Operations on page 4.
A FIELD FLUSH will occur sequentially for each programmed zone. Each zone will
flush for the initial 6 minutes of operation. Once the initial flush has occurred, the
controller will begin a normal dosing cycle.
The system test can also begin with an initial dose operation. This can be
accomplished by holding down the SILENCE ALARM button when turning on the
controller. Continue holding the button until ONE BEEP is heard, do not hold the
Silence Alarm button for more than 5 seconds or the controller will enter the
programming mode. Release the button and the pump will start. The pump will run for
the programmed dosing time and then go into a rest mode until time to start the next
scheduled dose.
The alarm float can be tested in two ways. It is recommended the test be done by
raising the high water float, by hand or with another object. The float should be held
slightly above the horizontal plane. The BDMC will go into its emergency mode. The
filter will flush for two minutes and then the pump will dose for ten minutes.
(Switch off
the pump BDMC breaker once it starts and the operation is verified. This will
keep the dosing field from over loading and potentially damaging it.)
The pump
will shut down. If the water level or float is below the horizontal plane, the BDMC will go
back into normal operation. If the high water float is still above the horizontal plane then
the pump will start again and run for 10 more minutes. If this does not eliminate the
high water condition, then the BDMC will stop the pump and set the alarm visually and
audibly. This is referred to
“Three Strikes and You’re Out”
. The BDMC will make
every attempt to lower the water and keep the system on line. Only when this is not
possible will the BDMC shut down the pump and set the alarm.
The second method
(shortest time)
to test the high water alarm is to fill the pump tank
to a point above the high water (alarm) float horizontal plane
or raise the float
manually
. Switch the controller into the programming mode. Select MODE 1. The
alarm will sound after the controller indicates the low float and mid (Sentry) float via
beep codes. The alarm float is always indicated by the audible alarm and red light.
