Terminal #3 

LITE

 turns on the monitor backlighting.  It may  be  supplied  from a  switch

that controls  other instrument lighting or it may be connected to Terminal #4  if you wish

the lighting to be on all the time. Set at the default value the backlighting consumes about

8mA (0.008A).  If left on all the time it would use less than 0.2Ahrs per day.

Consider the options for the next wire.

Terminal #4  the 

RED WIRE

 (+12V) is the  +12V supply to power the meter.    The wiring

diagram shows two options.  The preferred option is to   jumper together terminals #4 and

#5 as shown. Wired this way, the meter cannot accidentally be  de-powered.  It has the

disadvantage of always consuming a little bit of power from the #1 Battery.  The meter

consumes about  28mA (0.028A).  If left on all the time it would use about 0.7 Ahrs per day.

If the system is left on for long periods, (long enough to significantly discharge the

battery) with no charging sources, then you  should consider the option shown with the

dotted line.   In this case the RED wire is not jumped to the BLUE but supplied from the

common of the battery switch. (Be sure to install the 2A fuse as near the battery switch as

possible.)  Whichever battery is selected is the battery that supplies the power.

Caution:

 With this option, if the battery switch is turned off, the meter is de-powered

and resets Amp-hours to zero, therefore the battery switch must never be turned off except

when leaving the system for a long period of time.  When the system is returned to service

you must  resynchronize the meter by fully charging the battery.

Another option for the red wire is to  install a separate on/off switch in it before it

lands on the terminal board.  Just remember to turn off the meter when leaving the system

unattended.  (Ahrs will be reset to zero when the unit is repowered.)

Terminal #5 the 

BLUE WIRE 

(B1V) supplies Battery #1 voltage for sensing. It should be

supplied directly from  Battery #1.  Be sure to install the 2 Amp fuse shown in the drawing

as near the battery as possible.

Terminal #6 the 

VIOLET WIRE 

supplies Battery #2 voltage for sensing.  It should be

supplied directly from  Battery #2.  Be sure to install the 2 Amp fuse shown in the drawing.

  Note: If only one battery is to be monitored jumper terminal #5 & #6 together.

PROGRESS CHECK #1

The  wires  hooked  up so  far allow  you to check  the voltage monitoring  functions.

Install the fuse  that supplies Terminal #4 and 

carefully plug the ribbon cable into the

Monitor Terminal Board,  note index key and be sure the pins  are lined  up correctly.

From now on you may de-power the meter by unplugging the ribbon cable. If

you remove the fuse that supplies terminal #4, +12V, with the ribbon cable plugged

in  you must be careful when reinstalling it.  It must be a deliberate action.  If the power

to the meter is turned on and off in less than 5 second intervals it can cause the

microprocessor to interrupt its initialization process.  De-powering and re-powering

by using the ribbon cable avoids this problem.

Check each  of the  battery voltages.  It  is best to have a separate, accurate digital

voltmeter to  compare the voltages shown against the actual battery  voltage.  They  should

be within a few hundredths of a Volt.   If  they  are not,  check your voltage sense lead fuses

and fuse holders.  Any problems must be  resolved   before  proceeding.  If  you  have

questions call your dealer or  Heart Interface.   Unplug the ribbon cable before proceeding,

or remove the fuses in the wires to terminals #4, 5, & 6 before continuing.
