Dry Contact Relay
Remote Control Option
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 6 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 to the other position
on J22. J22 is located next to the relay.
To change the position of the jumper, rst 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 J22. It will be next to the relay 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 screws. Reconnect the unit to the power and load(s).
IMPORTANT: This remote is to be used only on
Voltage Converters manufactured by Analytic Systems.
A remote control panel may be connected to the voltage converter using a 9-pin D-connector
that attaches to the side of the voltage converter. The remote control panel and D connector
are part of the remote control option. The remote control panel allows the unit to be oper-
ated remotely as well as duplicating all the diagnostic indicators and audible alarm.
This connector is located on the side of the unit. Important: To prevent the possibility of High
Voltage Electrical Shock, do not power up the Voltage Converter unless all wiring from
the unit to the remote is securely connected. Do not remove the dust cover from the DB-9
connector if the remote is not being used.
