Monitor functionality
All functionality described in this section requires that the Monitor Ignition Input (Terminal B) be high in
order to be active. All of the fault outputs have internal pull-ups to the +24v supply of 10K ohm.
A. Alarm Low Output
This output is pulled to ground if the 24V bus is below 24 volts, indicating an alternator or
regulator failure.
B. Monitor Ignition (Enable) Input
This input enables the monitor function, when this pin is taken to +24V then the monitor becomes
active. See below for more information.
C. Ground
D. Imbalance Alarm Output
This output is pulled low if the batteries are out of balance by more than 6%, this could indicate a
12V bus overload, a dead battery condition, or an Equalization failure.
E. Alarm High Output
This output is pulled low if the +24V bus is above 30 volts, indicating an alternator regulator
failure.
F. Undervoltage Protection Override
If this pin is pulled high (more than 6V) the low voltage lockout on the lower battery is disabled,
this is to allow jump starts with two wire jump, the added protection is then not available. See
below for more information.
–Note: some Equalizers available in the market do not have undervoltage protection.
G. Equalizer Fault Output
This pin is pulled low when the Equalizer is faulty. See below for more information.
H. Equalizer Disable Input
This is a control pin for the Equalizer, if it is pulled low the Equalizer will be disabled. If it is left
disconnected, or pulled high, the Equalizer will function normally.
J. Remote Sense Fault Output
If the compensation voltage (the total difference between the voltages at the equalizer and the
voltages measured by the remote sense) exceeds 1.5v, the Remote Sense function is disabled and
this pin is pulled low.
K. Unused
L. Unused
M. +24V Battery Remote Sense
If this pin is connected directly to the +24V battery positive by a separate line, it will improve the
accuracy of the Equalizer balance of the batteries when load current is drawn. See below for
more information.
N. +12V Battery Remote Sense
If this pin is connected directly to the +12V battery positive by a separate line, it will improve the
accuracy of the Equalizer balance of the batteries when load current is drawn. See below for
more information.
P. Battery Ground Remote Sense
If this pin is connected directly to the battery ground by a separate line, it will improve the
accuracy of the Equalizer balance of the batteries when load current is drawn. See below for
more information.
The monitor output from the unit is through a Deutsch brand connector P/N: HDP20-18-14PN.
The mating connector is the Deutsch P/N: HDP26-18-14SN housing with Deutsch
P/N: 1062-16-0622 socket contact.
