Float High
When the Classic is in Float Mode, AUX 2 will be ON. AUX 2 will be OFF in all other modes.
Day Light
When the Classic notices DAWN, AUX 2 will turn ON; when the Classic notices DUSK, AUX 2
will turn OFF.
Nite Light
When the Classic notices DUSK, AUX 2 will turn ON; when the Classic notices DAWN, it will
turn OFF.
Clipper Control
PWM control of the MidNite Clipper. AUX 2 sends a PWM signal to the Clipper whenever the
Classic wants to unload the turbine because the battery is full, close to it, or the turbine’s
output voltage (input to the Classic) approaches the Classic’s input limit. AC or DC Clipper is
selected here. WIDTH and VOLTS can be adjusted to fine-tune the PWM output. The MAX V
setting in the sub-menu should be set just above the voltage in step 16 of the wind curve.
NOTE: If the AC/DC setting within the CLIPPER CONTROL mode is set to DC, then all
WIDTH functionality in all AUX 2 modes will be disabled. Set to either AC or DC based
on the Clipper model used for your wind turbine. If NOT using wind, then set to AC.
PV V on Low
When PV voltage is lower than set point volts, a PWM signal is turned ON. It will
automatically turn OFF if PV voltage rises above set point volts.
PV V on High
When PV voltage is higher than set point volts, a PWM signal is turned ON. It will
automatically turn OFF if PV voltage falls below set point volts.
Toggle Test
AUX 2 cycles in 1-second intervals between ON and OFF.
Waste Not Lo
This mode will turn AUX 2 ON when the Classic reaches a certain voltage set point (V LOW)
for each charging stage (Absorb, Float, EQ) and turn AUX 2 OFF when battery voltage exceeds
the set point. This mode will allow maximum diversion while maintaining 3-stage charging.
V LOW is the number of volts above or below the charging set points that you want to turn
AUX 2 ON: A negative value means the change of state occurs below the set point and a
positive value means the change of state occurs above the set point. Set WIDTH to 1.0V
unless specifically instructed to do so by our Support Team.
Example:
1. Float programmed in Classic at 54V.
2. Classic is currently in Float.
3. AUX 2 V Low is set at -2.0V
4. Then …. when battery voltage drops to 52V, AUX 2 will turn ON. When battery voltage
