Dry Contact Relay
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 on J10 to the other
position. J10 is located next to the relay K1.
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 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).
Remote Control Option
Remote Connector
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.
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 operated
remotely as well as duplicating all the diagnostic indicators and audible alarm.
