Voltage Regulation - Primus Wind Power AIR 40 Owner's Manual

OPERATION SUMMARY
(REGULATION MODES—continued)
REGULATION FLOAT:
When the battery voltage set point has
been reached, the turbine enters a temporary mode called REGULA-
TION FLOAT where the voltage is briefly monitored to confirm the high
voltage readings. Depending on the code revision, the LED will either
blink erratically (quick blinks followed by long blinks) or blink approxi-
mately 3 times per second. After a short time, the turbine will shift to
REGULATION STOP or back to POWER MODE (depending on the
battery voltage readings).
REGULATION STOP:
If the high voltage threshold is confirmed via
REGULATION FLOAT (per the potentiometer/battery regulation set
screw setting), the AIR shifts to REGULATION STOP and stops charging
the battery; blades will slow dramatically or stop. The turbine remains
in regulation until the battery voltage drops below the regulation set
point (cut-in voltage). The blades then resume spinning in response to
the available wind.
In REGULATION STOP, the turbine's LED will blink approximately once
per second or 3 times per second depending on the code revision level
of your turbine.
When the battery voltage drops to the cut-in voltage; which is slightly
lower than voltage set point, AIR re -enters REGULATION FLOAT and
subsequently POWER MODE. The difference between the two values is
termed "hysteresis" and is purposely done to prevent the turbine from
bouncing in and out of a single regulation set point.

OPEN CIRCUIT CONDITIONS:
electrical load (i.e. battery). This results in a cycle of rapid blade speed increas-
es followed by rapid braking. This accelerates turbine wear and is non-
productive. Primus Wind Power recommends:
•
Using a properly installed switch to turn AIR off for short periods of time
•
Lowering the turbine completely or securing the blades to prevent rotation if
the turbine will be shut down for an extended period of time
IMPORTANT:
The AIR turbine may not charge if battery open circuit voltage
drops below 10.5V (12V system), 21V (24V) and 42 V (48V system) as the internal
charge control circuit may not recognize that the battery is connected to the turbine
f when connected voltage drops further indicating a totally "dead" battery.
BASIC LED (light) FUNCTION:
•
LED at "power up" mode will have two slow "BLINKS" (this should be
verified prior to raising tower )
•
LED "SOLID" indicates "operation or charging mode"
•
LED "FAST" blink indicates "overspeed protection or regulation mode"
