Sterling Plumbing BB121250 User Manual

                 

this displays the output voltage and current of the 

battery you are charging. ( a less current but higher voltage ) 

( this is the setup information screen )  This screen gives different 

information depending on the system cycle, it is informing you., WET  OPEN= wet open lead acid cell batteries, 
this  shows that the  system battery type dip switches are set for wet cell batteries,( 14.8 v max setting ) Bulk 
charge refers to the initial charge rate, this could change to a timer, then adventually change to float ( float 
charger 14 volts )
                

  This screen shows the time left to the next pause cycle  

( for 2.5 min. ) and that it is on auto. The auto can be removed by pushing buttons 1 and 2 together. This 
removes the auto pause control, and the charger will still have all its safety and timing cycles, every 20 min. 
pause

 R:v2.0 C:v2.0, this shows the software version for 

remote ( R ) and for main PCB ( C ). the 12vIN-12vOUT, refers to the motel, a 12v-12v unit. There are 12-24 v, 
24-24 and 24-12.

:  There are 2 x screens on this button. Push once for screen a, then 

again for screen b. Screen a shows the alternator temp and the domestic battery temp, if the temperature 
sensors are not fitted it will default to 20 deg C

 Temp 4a+b:  There are 2 x screens on this button. Push once 

for screen a, then again for screen b. Screen b shows the box heat sink temperatures, LHS stands for left hand 
side, Guess what RHS stands for.
Do not expect these to be the same temperature
