I f you have a dual load controller (discontinued), then choose “CIS/CIS-N
Dual Load Versions” button instead.
These products can be identified by the 2 load wires and no thin black dimming
wire.
Non-Expert Mode
Non-Expert Mode is appropriate for users who have lead acid batteries who may
also want to use load programming and adjust low voltage disconnect (LVD)
settings or dimming settings.
4.1 Nightlight Function
The Nightlight Function menu is used to program load on/off and dimming on/off
controls based on time and reference points like dusk, dawn, or the middle of
the night. Use the graphical aid to see the effect of settings changes.
Remember, CIS family controllers intelligently detect day and night based on
solar PV voltage. If timer settings exceed the length of night at the install
location, the daytime solar PV voltage will still cause the load to turn off.
NOTE: The slider bar for length of night does not control anything. Use
the slider bar to see how nightlight settings will automatically adapt to
seasonal changes in night length.
There are 3 settings modes available:
- Standard Controller: Load is on all the time
- Dusk to Dawn:Load turns on at dusk and off at dawn
- Evening/Morning: Load turns on at dusk and off at dawn with an off period in between
Rather than turning the light off, you can choose dimming instead, or choose a combination of dimming and off hours. These features save battery energy to avoid low voltage disconnect events caused by bad weather or aging batteries.
Dimming is only available for CIS family controllers that have built-in LED
drivers, or when a CIS family controller dimming wire is connected to a
compatible LED driver. For CIS controllers with built-in LED drivers, dimming
is accomplished by pulse width modulation (PWM).
NOTE: Load disconnect events will override theload programming
timers.
For Dusk to Dawn (D2D) mode, check the box for “Turn light ON from Dusk to Dawn (Entire Night)”.
For Evening/Morning mode, check one or both boxes for “Turn light ON at dusk. Turn light OFF hour(s) [reference]’ or “Turn light ON hour(s) [reference]. Turn light OFF at Dawn.” Next, select your preferred time reference with the drop-down menu, either “based on dusk and dawn” or “based middle of the night”. Next, select your preference of hours using the drop-down menus. Use the graphic and slider bar to see how the settings would be implemented.
In the above example, there will be no off time when the length o f night is 10h or less.
In the above example, the load will not turn on if the length o f night is 6h or less.
Figure 4.5: Evening/Morning Example with Different Reference Points for Load
ON/OFF and Dimming ON/OFF In the above example, if the length o f night
decreases, dimming time will decrease.
To adjust the dimming level, use the drop-down menu. At 100%, lights will be
at full brightness when dimming is enabled. At 0%, lights will be off when
dimming is enabled. There is a linear correspondence in between.
4.2 SOC/LVD
Low voltage disconnect (LVD) protects lead acid batteries from damage by
preventing over discharge. Over discharge can lead to shortened battery
lifespan.
Low voltage dimming extends run time of lights when the batteries are not
fully charged due to bad weather or when batteries are aging and cannot hold a
charge.
There are 2 modes of LVD and low voltage dimming:
- Voltage controlled
- State of Charge (SOC) controlled
Voltage controlled LVD considers battery voltage only. When the controller
measures a battery voltage below the setting for a few minutes, it will
disconnect (or dim) the load.
SOC controlled LVD considers battery voltage and load current. When load
current is high, the controller will wait for a lower battery voltage before
disconnecting (or dimming), and it will wait longer before disconnecting (or
dimming).SOC settings are valuable because battery voltage alone is not
acomplete indicator of battery state of charge.
Battery voltage must be below the setting for longer than 2 minutes and up to
30 minutes for LVD or low voltage dimming to take effect. Low voltage dimming
settings must be higher than LVD settings to take effect.
IMPORTANT: Program all settings for a 12V battery. CIS charge controllers
will automatically detect 12 or 24V batteries and automatically adjust
settings for 24V systems.
To determine when SOC settings will apply, you will need to know the load
currentconsumption and the controller’s load current rating. For example,
CIS-N-MPPT-85/20 is rated for 20A. If a connected streetlight was consuming
14A, that would be 70%, or 0.7, of the controller’s nominal current capacity.
If SOC4 was selected, the graph below shows the battery voltage must drop
below 11.55V for the controller to implement LVD, There is also a time delay.
4.3 Night Detection Threshold
As dusk turns to night, solar voltage drops to a very low level. As night
turns into dawn, solar voltage increases from a low level up to levels that
can be used for battery charging. CIS family charge controllers intelligently
detect this change of state by utilizing the Night Detection Threshold
setting. Night Detection Threshold is only relevant for Dusk to Dawn or
Evening/Morning load settings. Night Detection Threshold is the PV array open
circuit voltage at which the controller will determine the night state, Night
Detection Threshold + 1.5V is the level at which the controller will determine
the day state.
Increasing the voltage means the load will turn on sooner at dusk and turn off
later at dawn. Decreasing the voltage means the load will turn on later at
dusk and turn off sooner at dawn. If this setting is too low and there is
ambient light, then the controller might not be able to transition to night
properly.
To change this setting, mark the checkbox and use the dropdown.
4.4 Battery Type
The “Lead acid battery” setting enables equalization charging. This is
intended for flooded or liquid electrolyte lead acid batteries. The “Sealed
battery” setting disables equalization charging.
CAUTION: Always follow the charging recommendations of your battery
manufacturer.
4.5 Printor Send
Use the “Printer preview window’ or “Print” buttons to trigger the Windows
printer dialogue box and printa picture of the CIS-CU settings. Or, use the
“Send Settings” button to transmit settings to a CIS family controller via
the MXI-IR accessory.
5.0 Expert Mode
Expert Mode is appropriate for users who:
- have lithium ion batteries
- need access to additional low voltage disconnect options (LVD)
- have CIS-‘N-MPPT-LED or CIS-N-LED and need to program the LED current
- need to save settings files for later use
- have experience with solar design, batteries and CIS family charge controllers
WARNING: Do not adjust settings in Expert Mode if you do not know the
purpose or effect.
Incorrect settings can damage batteries, cause excessive gassing, and create
fire or explosion hazards.
CAUTION: Always follow the recommendations of your battery manufacturer.
IMPORTANT: Program all settings for a 12V battery. CIS charge controllers
will automatically detect
12 or 24V batteries and automatically adjust settings for 24V systems.
5.1 Enable or Disable Expert Mode
To enable Expert Mode, select the “Expert Mode Disabled” status button from
the main menu. To disable Expert Mode, select the “Expert Mode Enabled” status
button from the main menu.
5.2 Nightlight / Low Battery Settings
Load 1 is the load output for single load controllers such as CIS-N and
CIS-N-MPPT, Load 2 is the dimming control signal for single load controllers.
NOTE: Load disconnect events will override theload programming timers.
Day and night detection will override any load programming timers for 02D or
Morning and Evening.
IMPORTANT: Program all settings for a 12V battery. CIS charge controllers
will automatically detect 12 or 24V batteries and automatically adjust
settings for 24V systems.
Nightlight / Low Battery Settings | Description |
---|---|
Nightlight Mode (Load 1) | No Nightlight will turn the load output on all the |
time. (Standard Controller)
D2D will turn the load output on at dusk and off at dawn.
Morning and Evening hours based on Dusk & Dawn will use dusk and dawn as
reference points for hourly settingswith evening hours after dusk and morning
hours before dawn.
Morning and Evening hours based on Middle of the night will use the midpoint
between dusk and dawn as a reference point for hourly settings with evening
hours before the middle of the night and morning hours after the middle of the
night.
ON Hours After Dusk (Load 1)| With Morning and Evening hours based on Dusk &
Dawn, this is the number of hours the load will be on after dusk.
With Morning and Evening hours based on Middle of the night, this will be the
number of hours before the middle of the night when the load will turn off.
ON Hours Before Dawn (Load 1)| With Morning and Evening hours based on Dusk &
Dawn, this is the number of hours the load will be on before dawn.
With Morning and Evening hours based on Middle of the night, this will be the
number of hours after the middle of the night when the load will turn on.
LVD Indicator Type (Load 1)| SOC is a battery state of charge controlled low
voltage disconnect. Voltage is a battery voltage controlled low voltage
disconnect.
LVD load 1 Offset| With SOC LVD, higher numbers disconnect the battery at a
higher SOC. Lower numbers disconnect the battery at a lower SOC.
With Voltage only LVD, the setting will be the battery voltage offset added to
the base voltage. The sum of these voltages will be the battery voltage level
thattriggers LVD.
LVD: Base + Offset (V)| This is the automatic calculation of the sum of the
base voltage and offset voltage used to trigger LVD.
Nightlight Mode (Load 2)| No Nightlight will keep dimming off except by LVD.
D2Dfor Load 2 is not applicable to dimming features at night. Setting No
Nightlight for Load 1 and D2D for Load 2 will dim the light during the day and
switch to full brightness at night.
Morning and Evening hours based on Dusk & Dawn will use dusk and dawn as
reference points for hourly settings with evening hours after dusk and morning
hours before dawn. Evening hours are the delay after dusk until dimming is
implemented. Morning hours are when dimming will end before dawn, and the
light will switch to full brightness.
Morning and Evening hours based on Middle of the night will use the midpoint
between dusk and dawn as a reference point for hourly settings with evening
hours before the middle of the night and morning hours after the middle of the
night. Evening hours are the number of hours before middle of the night when
dimming will start. Morning hours are the number of hours after middle of the
night when dimming will end.
The load must be on for dimming to take effect.
---|---
ON Hours After Dusk (Load 2)| With Morning and Evening hours based on Dusk &
Dawn, this is the delay when dimming will take effect after dusk.
With Morning and Evening hours based on Middle of the night, this will be the
number of hours before the middle of the night when dimming will take effect.
The load must be on for dimming to take effect.
ON Hours Before Dawn (Load 2)| With Morning and Evening hours based on Dusk &
Dawn, this is the number of hours before dawn when dimming will stop.
With Morning and Evening hours based on Middle of the night, this is the
number of hours after the middle of the night when dimming will stop and the
light will switch to full brightness.
The load must be on for dimming to take effect.
LVD Indicator Type (Load 2)| SOC is a battery state of charge controlled low
voltage dimming. Voltage is a battery voltage controlled low voltage dimming.
LVD load 2 Offset| With SOC low voltage dimming, higher numbers implement
dimming ata higher SOC. Lower numbers implement dimming at a lower SOC.
With Voltage onlylow voltage dimming, the setting will be the battery voltage
offset added to the base voltage. The sum of these voltages will be the
battery voltage level that triggers low voltage dimming.
The load must be on for dimming to take effect.
LVD: Base + Offset (V)| Automatic calculation of the sum of the base voltage
and offset voltage used to trigger low voltage dimming. This must be higher
than the value for Load 1 for dimming to take effect.
Day/Night Threshold| PV array voltage at which the controller will switch from
day to night mode. The controller will switch from night to day at 1.5 / 3.0V
above this level.
---|---
Battery Type| Gel disables Equalize Charging. Flooded enables Equalize
Charging.
Dimming percentage| For CIS controllers with a dimming wire, 100% corresponds
to a 10V signal, and 0% corresponds to a OV signal on the dimming wire. There
is a linear correspondence in between.
For CIS controllers with integrated LED drivers, 100% corresponds to full
brightness, and 0% corresponds to off. There is a linear correspondence in
between.
Dimming is accomplished by PWM.
Dimming Base Level Value| For CIS-N-MPPT-LED:
This setting reduces LED output current linearly and is a percentage of the
maximum 3SOOmA output 100% corresponds to 3500mA, and 0% corresponds to OmA
with a linear correspondence in between.
Linear LED output current before dimming= 3SOOmA (Dimming Base Level Value
%)
For example, if the desired LED current before dimming is 2500mA, then select
70.0.
(2500mA/3500mA)100 = 71.4%
70.0% is the closest allowable value below 71.4%.
Any Load 2 settings for dimming will apply the dimming percentageto the
adjustedvalue, but dimming will be rd For CIS-N-LED:
This setting reduces LED output current by PWM and is a percentage of the
nominal rated value. Any Load 2 settings for dimming will additionally apply
the dimming percentage, and dimming will be accomplished by PWM.
5.3 Battery Charge Regime Settings
Battery Charge Regime Setting | Description |
---|---|
Emergency High Voltage | Fast acting protection intended primarily for a wiring |
error, when a fuse blows, or to stop charging when a secondary source (i.e.
generator) is unregulated or in error.
Maximum Charge Voltage| Highest charge voltage allowed by temperature
compensation. (Higher values can often be seen in the datalogger due to quick
fluctuations from high C-rates.)
Equalize Voltage| Equalize voltage at 25°C.
Only active when the Battery Type setting is selected as Liquid. It’s disabled
when Gel is selected.
This stage is chosen if the battery was discharged <12.1/24.2V the night
before. Overrides Main and Boost charge.
---|---
Boost Voltage| Boost (Absorption) voltage target at 25°C.
Setting applies to both the 2hr Boost charge and the 30min Main charge.
The 2hr is chosen if the battery was discharged <12.3/24.6V the night before.
Overrides the 30min Main charge.
Minimum Boost Voltage| Lowest Boost (Absorption) or Equalize charge voltage
allowed by temperature compensation.
Float Voltage| Float voltage at 25°C.
Minimum Charge Voltage| Lowest Float charge voltage allowed by temperature
compensation.
Load Reconnect Voltage| After dimming due to low voltage or LVD has occurred,
they will continue until the battery bank is charged above this level.
Emergency Low Voltage| Fast acting protection intended primarily for a wiring
error or old batteries. Similar to LVD, but immediate.
Base Voltage LVD| Reference voltage for adjusting voltage controlled LVD
settings. An offset is added to this voltage to create the final LVD or
dimming voltage settings.
Base Voltage SOC| Referencevoltage for adjusting SOC controlled LVD settings.
This reference voltage will be the battery voltage when no load current is
flowing.
Maximum step for SOC| A step for how the SOC LVD setting will compensate for
load current.
Temperature Compensation| Units of millivolts. The “negative” is already in
the internal calculation. It’s the total for a 12V battery (6 cells). In cold
weather, the target charge voltage will be increased by this amount for every
degree below 25°C. In hot weather, the target charge voltage will be decreased
by this amount for every degree above 25°C.
Referencing K instead of °C helps avoid confusion with negative signs when the
ambient temp is <0°C.
5.4 Pre-programmed Battery Charge Regime Settings
Expert mode includes three buttons for preprogrammed battery charge setting
profiles:
- “Lead acid”
- “LFP full capacity”
- “LFP extended life”
Battery Charge Regime Settings will automatically change in the software.
Battery Type must be updated manually if required.
When Battery Type is Gel, the “Lead Acid’ profile is best suited for AGM, gel,
or other sealed type lead acid batteries. When Battery Type is Liquid, the
Lead Acid profile is best suited for flooded or wet cell type lead acid
batteries that need the Equalize charge stage enabled.
“LFP full capacity” is for lithium iron phosphate batteries with a BMS where
charging to 100% capacity is a priority with a tradeoff in lifespan.
“LFP extended life” is for lithium iron phosphate batteries with a BMS where
extended lifespan is a priority with a small tradeoff in capacity.
5.5 Saving Settings Files
To save settings files, either read the controller settings or program them.
Select the “Save Data” radio button. Select the “Save CISCOM Data .cis”
button. Use the file explorer to name and save the settings file.
