To use your dry contact output fail relay you must connect a 9-pin D connector to the unit.
You must use pins one and six as is indicated on page 7 in the remote connector diagram.
The relay is factory preset to fail in the closed position when the low output LED and buzzer
come on. If you wish to have the relay fail in the open position when the low output LED
and buzzer come on, you must take the cover off the unit and move the jumper on J10 to the
other position. J10 is located next to the relay K1.
To change the position of the jumper, first turn the unit off and disconnect the unit from both
the power and load(s). Next, turn the unit on for 30 seconds to discharge the capacitors,
then turn it off again. Remove the eight screws holding on the cover. Turn the unit upside
down, remove the cover and locate J10. It will be next to the relay K1 as is shown in the
above diagram. Simply move the jumper to the desired position as is shown in the above
diagram. Replace the cover and re-install the eight cover screws. Reconnect the unit to the
power and load(s).
Dry Contact Relay
Meters
High quality digital meters can be added to the charger (factory installed only). Both outputs
can be monitored for current and voltage.
The units may be configured for load sharing if they are equiped with the optional output
isolation diodes. To confirm that your unit has these diodes, use an ohmmeter to measure the
resistance between the two positive output terminals. If the diodes are present the terminals
will measure as not connected. If the diodes are NOT present, the terminals will measure as
a short circuit. Assuming the output isolation diodes are present, connect a one-foot piece of
red wire of the appropriate gauge (as shown in the table below)
