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 posi-
tion on J5. J5 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 input power and load(s). Next, turn the unit on for 30 seconds to discharge the capacitors,
then turn it off again. Remove the six screws holding on the cover. Turn the unit upside down,
remove the cover and locate J5. 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 six screws. Reconnect the unit to input and output power.
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 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
converter using a 9-pin D-connector, which attaches
to the front panel 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.
