Auxiliary Relays in the Classic

[Halfcrazy]

Ok here is a list of the Auxiliary 1 modes that will be in the Classic with the next firmware release coming in a week or two. These are all in there now just worded different and float mode is not working in the current firmware. i will work on Auxiliary 2 next and post them later. I will also be working on simple one page instructions on programming each of these modes. I hope to get all this done and in the manual in time for there release in the new firmware.

Aux 1
Vent Fan Lo
This mode will turn Aux 1 off above the voltage set point you program. It allows you to run a vent fan for a battery bank based on battery voltage. There is a voltage set point that you set and Aux 1 will turn off when the battery reaches that set point. The voltage has to fall 2 tenths of a volt below the set point for 30 seconds before Aux 1 will turn back on.


Vent Fan High
This mode will turn Aux 1 on above the voltage set point you program. It allows you to run a vent fan for a battery bank based on battery voltage. There is a voltage set point that you set and Aux 1 will turn on when the battery reaches that set point. The voltage has to fall 2 tenths of a volt below the set point for 30 seconds before Aux 1 will turn off.


Float Low
This mode will turn Aux 1 off whenever the Classic is in Float. Aux 1 will stay off until the Classic falls 3 tenths of a volt below the float voltage set point.


Float High
This mode will turn Aux 1 on whenever the Classic is in Float. Aux 1 will stay on until the Classic falls 3 tenths of a volt below the float voltage set point.


Clipper Control
This mode was intended to control the MidNite Clipper. It will send out a PWM signal whenever the controller is unloading the turbine because the battery is full or close to it. There are no adjustment in this mode the Classic is preprogrammed with the best parameters to control turbine RPM.


Day Light
This mode will turn Aux 1 on at sunrise and turn it off at sunset based on the PV input voltage.


Nite Light   
This mode will turn Aux 1 on at sunset and turn it off at sunrise based on the pv input voltage.


Toggle Test
This mode will cycle Aux 1 for 1 second off and 1 second on repeatedly. This mode is mostly for testing purposes.


Pv V on Low
This Mode will turn Aux 1 off above a user set voltage based on the input voltage to the Classic ( V High) and turn Aux 1 on when it hits a low voltage set point (V Low). It also allows you to set a delay time in seconds the Classic will wait before turning Aux 1 off after reaching the V High set point. It also allows you to set a hold time in seconds the Classic will wait before turning Aux 1 on after reaching the V Low set point. This mode can be useful for controlling a failsafe stopping system for Hydro or Wind.


Pv V on High
This Mode will turn Aux 1 on above a user set voltage based on the input voltage to the Classic ( V High) and turn  Aux 1 off when it hits a low voltage set point (V Low). It also allows you to set a delay time in seconds the Classic will wait before turning Aux 1 on after reaching the V High set point. It also allows you to set a hold time in seconds the Classic will wait before turning Aux 1 off after reaching the V Low set point. This mode can be useful for controlling a failsafe stopping system for Hydro or Wind.


Opportunity Lo
This mode will turn Aux 1 off when the Classic gets within a certain range of the voltage set points for each charging stage (V High) and turn Aux 1 on when it gets to a low set point (V Low). These set points are user adjustable and will allow the Absorb, Float and EQ timers to continue to run. You will adjust these set points to negative numbers and the numbers are an offset from the voltage set point. For example a  -.2 would turn Aux 1 off 2 tenths of a volt below your set points. This mode will allow you maximum diversion while maintaining your 3 stage charging.  It also allows you to set a delay time in seconds the Classic will wait before turning Aux 1 off after reaching the V High set point. It also allows you to set a hold time in seconds the Classic will wait before turning Aux 1 on after reaching the V Low set point.


Opportunity Hi
This mode will turn Aux 1 on when the Classic gets within a certain range of the voltage set points for each charging stage (V High) and turn Aux 1 off when it gets to a low set point (V Low). These set points are user adjustable and will allow the Absorb, Float and EQ timers to continue to run. You will adjust these set points to negative numbers and the numbers are an offset from the voltage set point. For example a  -.2 would turn Aux 1 on 2 tenths of a volt below your set points. This mode will allow you maximum diversion while maintaining your 3 stage charging.  It also allows you to set a delay time in seconds the Classic will wait before turning Aux 1 on after reaching the V High set point. It also allows you to set a hold time in seconds the Classic will wait before turning Aux 1 off after reaching the V Low set point.


Low bat disc
This mode will turn Aux 1 off when it reaches a set point based on battery voltage (V High) and turn it on at another set point based on battery voltage (V Low). It also allows you to set a delay time in seconds the Classic will wait before turning Aux 1 off after reaching the V High set point. It also allows you to set a hold time in seconds the Classic will wait before turning Aux 1 on after reaching the V Low set point. This can be used with a NC relay when the battery gets to the set point the Classic will send 12vdc to the relay holding it open and disconnecting the load.


Diversion
This mode will turn Aux 1 on when it reaches a set point based on battery voltage (V High) and turn it off at another set point based on battery voltage (V Low). It also allows you to set a delay time in seconds the Classic will wait before turning Aux 1 on after reaching the V High set point. It also allows you to set a hold time in seconds the Classic will wait before turning Aux 1 off after reaching the V Low set point.

Ok here is a list of Aux 2 functions and there descriptions. These are all outputs listed below Aux 2 does have the ability to be an input as well we just have not programmed any inputs yet. You will notice a lot of the same functions as Aux1 some of them are PWM signals here and just on/off on Aux1. These are mostly in the Classic now but worded different. Look for these on the soon to be released firmware update. You will also notice we have High and Low on all the functions this is to allow the use of NC relays instead of NO when it makes sense to do so for whatever the reason may be. The old MX60 had the ability to set the Aux active High or Low we just chose to give each function a High and Low to save programming steps. The Aux portion of the Classic is going to be rather large and detailed so the less things people have to dig for the better it should be for them?

Aux 2   

Float Low
This mode will turn Aux 2 off whenever the Classic is in Float. Aux 2 will stay off until the Classic falls 3 tenths of a volt below the float voltage set point.


Float High
This mode will turn Aux 2 on whenever the Classic is in Float. Aux 2 will stay on until the Classic falls 3 tenths of a volt below the float voltage set point.


Day Light
This mode will turn on Aux 2 at sunrise and turn it off at sunset based on the PV input voltage.


Nite Light   
This mode will turn on Aux 2 at sunset and turn it off at sunrise based on the pv input voltage.


Clipper Control
This mode was intended to control the MidNite Clipper. It will send out a PWM signal whenever the controller is unloading the turbine because the battery is full or close to it. There are no adjustment in this mode the Classic is preprogrammed with the best parameters to control turbine RPM.


Pv V on Low
This mode is PWM based and is just reverse logic of Pv V High. It would be comparable to using the NC contacts of the relay used in Pv V High. It can be used that way with a solid state relay with NC contacts for a failsafe load.  


Pv V on High
This mode is PWM based and will PWM Aux 2 above a user set voltage (V High) based on the input voltage to the Classic and stop when it hits a low voltage set point (V Low).


Toggle Test
This mode will cycle Aux 2 for 1 second off and 1 second on repeatedly. This mode is mostly for testing purposes.


Opportunity Lo
This mode is PWM based and is just reverse logic of Opportunity Hi. It would be comparable to using the NC contacts of the relay used in Opportunity Hi. It can be used that way with a solid state relay and NC contacts to do diversion above a set voltage.  


Opportunity Hi
This mode is PWM based and will PWM Aux 2 when the Classic gets within a certain range of the voltage set points for each charging stage (V High) and stop when it gets to a low set point (V Low). These set points are user adjustable and will allow the Absorb, Float and EQ timers to continue to run. You will adjust these set points to negative numbers and the numbers are an offset from the voltage set point. For example a  -.2 would turn Aux 2 on 2 tenths of a volt below your set points.

Diversion Hi
This mode is PWM based and will PWM Aux 2 at a set point based on battery voltage (V High) and stop it at another set point based on battery voltage (V Low).

Thanks!

I don't know if it's been discussed, but I would love to see an Aux 1 function based on battery temp. (Aux 1 changes state based on temp set-points)
Any possibility of this?

Thanks

Yes this is on the short list it will simply change the state of Aux 1 based on a user set temperature that the BTS reports. It may be a little bit though as boB is knee deep in data logging and parallel communications.

Just knowing that it is in the works is great news!
No pressure or anything, but I could really use this in a month or so... 

Thanks!
