MODEL A36D SERIES - INSTRUCTIONS AND TROUBLESHOOTING
Page 15 of 33
When remote sensing is wired, the unit output may have to be readjusted to compensate for the protection
diodes on the circuit board.
CAUTION: The polarity of the sensing terminals is critical. Check and verify the polarity carefully.
7.4 REMOTE EQUALIZE TERMINALS
NOTE: Remote equalize can only be used with other A36D Battery Chargers.
A terminal is provided on unit (RE) for a remote equalize function. The unit may be remotely forced into
equalize by connecting the “RE” terminal to negative.
Caution: Damage to the unit will result if the Remote Equalize Terminals are shorted to any other AC or DC
voltage source or ground on positive grounded units. In a system all unit “RE” terminals are
connected together and when any one master unit is put into equalize, all units will go into
equalize and display will read “RE”. To return to the float mode this master unit must be returned
to the float mode.
7.5 LOAD SHARING
When the load sharing Terminals (LS) are connected together, multiple units are forced to share the load
current /- 5%. Individual unit outputs must be greater than 10% of the rated current output.
Caution: Damage to the unit will result if the Load Sharing Terminals are shorted to ground or any other AC
or DC voltage source.
NOTE: If only one unit picks up the load, momentarily put the unit with no load into the
equalize mode, and then back to the float mode. The units should share load equally.
8.0 OPERATION
8.1 START UP
When all connections have been made, place the units’ AC breaker in the “ON” position, and turn “ON” the
DC breaker.
Verify the output voltage, output current, and the alarm and status lights to be sure the unit is operating
properly.
If the unit is not operating correctly check the connections again and read Section 12 , “TROUBLE
SHOOTING”.
8.2 CAPACITOR PRE-CHARGE INSTRUCTIONS
WARNING: READ INSTRUCTIONS BEFORE CONNECTING BATTERY to prevent the DC output fuse from
blowing when connecting the battery, connections to the power supply and batteries should be done in the
following order (single power supply).
Connect AC input line to the terminal block provided. Be sure the units’ AC circuit breaker is
off.
Observe the polarity of the battery cables, charger output, and relay rack terminals.
Connect the proper battery cable to the ground bar or battery charger output terminal.
Now energize the power supply by turning on the units’ AC breaker. This will charge the
capacitors inside the power supply and eliminate heavy arcing when the remaining battery
cable is connected. After approximately one (1) minute, turn off the power supply and
immediately connect the remaining battery cable.
Connect loads.
Now turn on the power supply again and the charger will commence charging the batteries and powering
the load. (NOTE: For units equipped with a low-voltage disconnect panel, the “Load On” switch must be
put in the “Load On” position.)
