12. TO ACTIVATE AND DEACTIVATE REMOTE CONTROL MODE
The Remote control terminal is disabled by default at the factory and the output is always on.
To enable the Remote Control Mode, apply a positive 8 to 32VDC to Remote terminal.
After Remote Control Mode has been enabled it will stay enabled until it is disabled or reset to factory default
setting in 12.
To disable remote control mode
-
Press and hold SET button until
is shown.
-
Release button then wait for few seconds. The remote control will be disabled and the output will stay
always ON.
13. FACTORY DEFAULT SETTINGS
1.
Unit is in DC-DC Converter Mode with Output Voltage set at 13.8V
2.
Remote Control is disabled and the Output is always ON.
You can reset DC-DC Converter to factory default setting by following steps:
-
Press and hold SET button until
is shown.
-
Release button then wait for few seconds. The converter is reset back to factory default setting.
14. DISPLAY ON/OFF
The display will be switched off automatically after 5 minutes. Press the Set Button to restart the display for
another 5 minutes.
15. ALWAYS ON AUXILIARY OUTPUT
The DC-DC Converter will provide constant 12V, 0.5A to power critical devices such as security or alarm and
will supply a positive voltage source for manual remote On/Off control of the output.
Upon connection of the input to the 48V battery supply, the 12V terminal will be powered.
16. REMOTE VOLTAGE SENSING PORTS
The remote voltage sensing operates for both Converter mode and Charger mode. It compensates for
voltage drop at a distant load or auxiliary battery.
It further enhances the stability of the output voltage to the distant connected load or battery.
Connect the cable from the Positive S+ to Positive of load / battery and Negative S- to Negative of load/
battery.
17. ALARM --
The low input voltage pre-warning
The alarm signal port provides 12V 0.25A for external LED or other alarm device to give pre-warning signal
when input voltage drops below 42V before further dropping to 38V at which the output shuts down.
18. LOW CURRENT DISPLAY
The display will show
when the output current is less than 1Amp.
The converter can be in converter or charger mode or when the output is open circuit.
When in Battery Charger mode, it will mean that the battery is charged.
