Polarity
PV Trigger
Function
:
When the
Enable Voltage
set point is exceeded, the
A
UX
output will activate.
Once the voltage decreases below the set point, the
output will remain active for the duration of the
Hold
Time
set by the user.
Purpose
:
This mode operates an alarm or a PV cutoff relay
when PV voltage exceeds a safe value.
Enable
Voltage
Hold Time
Active High
:
Activates when the
voltage exceeds the
set point.
Active Low
:
Activates when the
voltage drops below
the set point;
deactivates when
the voltage exceeds
the set point.
CAUTION:
Hazard to Equipment
Do not exceed 300 Vdc or the FLEXmax
100 could be damaged.
Error Output
Function
:
This mode responds to two emergency conditions:
low battery or failure to charge. Low battery is
defined by
Low Battery Voltage
. Failure to charge
means the PV has not exceeded the battery voltage
by 3 Vdc or more for 26 consecutive hours. Either
case may mean an array problem.
This mode is
Active Low
only. The
A
UX
output is
normally active. When either condition is met, the
A
UX
will deactivate.
Purpose
:
This mode is useful for monitoring remote sites. It
indicates when the controller has not charged the
batteries for 26 hours or more or if the voltage
remains too low for other reasons.
Deactivation is intended to operate a remote alarm.
It can send a signal through a modem to alert a
computer of the problem.
Low Battery
Voltage
Active Low
only.
Deactivates when
the voltage drops
below the set point
for 10 minutes.
Night Light
Function
:
When the PV voltage drops below the
Threshold
voltage set point for the
Hysteresis Time
, the
A
UX
output changes states and remains in that state for
the
ON Time
setting.
Purpose
:
This mode is intended to illuminate a small
(user-provided) light for as long as the controller
remains in
Sleep
mode or for the
ON Time
setting.

Active High
:
Activates for a set
time when the
voltage drops below
the set point for a
set amount of time.
Active Low
:
Activates for a set
time when the
voltage exceeds the
set point for a set
amount of time.
Deactivates when
the voltage drops
below the set point.
