How do I verify Follow
Me is working properly?
*You should first go to the Main menu and then into the “Temps” menu and
verify all controllers are seeing the Battery Temp from the one with the BTS
plugged in.
*You should also see a blue LED flashing inside the top vent. There are two
types of blink, A short blink that is about one tenth of a second means it is
getting good information. A long blink that is about half a second indicates it
did not get any info. If the blinks are ALL long then you probably have a bad
cable and all cables should be checked immediately
The Fans seem way to
loud
*If it is the internal fans make sure no wires or anything have come in contact
with them inside the wiring compartment
*If it is the external fan you may want to remove the front half of the “Turbo”
plastic housing and make sure the fan is still adhered into the back plastic
housing. If the fan has come loose a dab of silicone on each side should solve
the noise issue. Please make sure not to get any silicone on the fan blades
Updating the firmware
and the Classic went
well but the MNGP will
not update
*Make sure the MNGP (Display) is actually plugged in using the blue display
cable in the top jack of the main circuit board
*Verify you have an MNGP and not an MNLP. The MNLP is an LED panel
that comes with the Classic Lite and does not need to be updated
*When the black box pops up telling you to power the Classic up, Count to 4
before turning the breaker on
*If you do not have a breaker or disconnect and you are trying to connect a
wire to a terminal block or a battery the connection will likely be to dirty for
the boot loader. Install the proper breakers
Classic goes to absorb at
too low of a voltage
*Verify this is not normal operation do to the battery being warmer than the
neutral point. You can verify the battery temperature by going into the main
menu and selecting the “Temps” menu. The Classic like all other chargers will
adjust the actual charge voltage based on the temperature of the battery. It uses
2 variables you program in for this. 1-Temperature neutral point (Typically 25
degrees C) and this is found in the WBjr set up menus. 2-Milli volts per degree
C per cell (typically -5Mv). So verify both of these are set per the battery
manufacturers specs.
So for an example if Absorb was set for 58.8 volts and the battery is at 35
degrees C and the temp comp is set for -5mv we have a 10 degree C
difference:
10 x 24 = 240 x 5 = 1200Mv or 1.2v so the Classic would actually charge to
57.6v
Classic goes to absorb at
too high of a voltage
*Verify this is not normal operation do to the battery being cooler than the
Neutral point. You can verify the battery temperature by going into the main
menu and selecting the “Temps” menu. The Classic like all other chargers will
adjust the actual charge voltage based on the temperature of the battery.
See above calculation’s the same works for cold batteries as well you just end
up with a negative number so a battery that is 15 degrees C would look like:
-10x24 = -240x5 = -1200Mv or -1.2v so the Classic would actually charge to
60v
