Remove and safely brake charging sources
such as wind/solar/hydro. When in doubt, use a
qualified electrician. Missouri Wind and Solar,
LLC is not responsible for damages or injuries
caused by misuse or improper programming.
DANGER! SHOCK WARNING: Wind, solar,
hydro, batteries etc. may produce lethal
voltages! Use extreme caution.
Preset controller configuration
(use ½ these
voltages for a 12v system)
:
divert relay on at
28.8 battery volts, start relay off timer at 27.2
battery volts, relay off timer 5 seconds after
27.2 volts is reached. If battery voltage does
not fall below 27.2 volts, the relay will stay on.
WE RECOMMEND YOU DO NOT CHANGE
THE CONTROLLER
’S SETTINGS UNLESS
YOU ABSOLUTELY NEED TO. READ AND
UNDERSTAND ALL INSTRUCTIONS
INCLUDED WITH YOUR EQUIPMENT.
WARRANTY WILL BE VOID IF THE
SETTINGS ARE CHANGED
UNECCESSARILY.
Possible reasons to change settings
:
You have an inverter charger or other charge
controller which may charge batteries to above
28.8 volts. If another charging source performs
an equalize charge, you can leave the factory
settings alone and safely disconnect the
Missouri Wind Digital Controller while an
equalize charge is taking place.
Outback Inverter Charger/Grid feed
inverters
: Typically adjust the DIG controller
high volt trip point to 15 volts (12v system) or
29.5 volts (24v system).
To change settings:
1. Connect the small sense wires to proper
battery voltage or use a dc power supply
(red wire +, black wire -).
2. Wait 6 seconds.
3. Use the two black push buttons below volt
meter
“set” & “enter.”
You will be entering P-1 for time setting, P-3
for voltage set points.
4. Hold
“enter” until you see “P-3 display”,
then release.
5. Short press
”set” until you see “P-1”
display. This is the time setting. Time
setting is recommended for experienced
users as this changes the amount of time
the relay is on after battery falls to 27.2v, or
13.6v.
6. Press
“enter.” You will see “005.” This is 5
seconds. Short press
“set” to move the
flashing digit from left to right. Stop on the
digit for the preferred setting. Press
“enter”
to confirm the new setting.
If you pass the desired digit, continue to
short press
“set” until you cycle back
around to it.
7. After first 3 digits are changed, press
“set”
to view the second set of 3 digits. This is
the relay activity timer (RAT). Relay activity
timer starts countdown every time the relay
turns off. The RAT time period is preset at
5 seconds.
Relay Activity Timer:
Assuming the RAT is
005 (5 seconds), when the relay has activity
(turns on then off) the RAT will immediately
start a countdown from 5 to 0 seconds.
If the relay turns on again before the
countdown reaches 0, the relay will stay on for
10 seconds then relay off and RAT countdown
starts from 5 to 0 seconds again.
If the relay turns on again before countdown
reaches 0, the relay will stay on for 20 seconds
then relay off and RAT countdown starts from 5
to 0 seconds again.
If the relay does not turn on again before RAT
countdown reaches 0, then the next time the
relay turns on again it will be on for 5 seconds.
The relay must turn on again before the RAT
time reaches 0, otherwise the relay
’s on time
will stay at 5 seconds.
The RAT's purpose is to hold the controller in
divert for an increasing amount of time
because your controller is repeatedly diverting
within a short period of time (i.e. batteries
nearing full).
Referring to the example above, 20 seconds is
the maximum amount of time the relay will stay
on if the conditions continue to be met. If you
change the RAT (the second set of 3 digits) to
20 seconds (020 on display), then relay on time
will be 20 sec, 40 sec, 80 sec, 80 sec, 80 sec.,
etc.
In most systems there is no need to
change the RAT.
8. The third set of digits will appear as: d-9.
This means the LED display will turn off
after 9 minutes if no buttons are pressed
(user is not changing settings). Changing to
d-0 means the display will always remain
on.
You can turn the display back on at any
time by short pressing any button.
9. After the third set of digits, you will see your
first time setting with no flashing digits.
Hold
“enter” until you see P-1.
You are now done with the time (P-1)
settings.
Stop, do not press any buttons or make
changes.
10. If you don't need to change the preset high
or low voltage points, you still need to enter
into P-3 directly after programming P-1. If
this is the case, short press
“set” until you
