The relay is intended for automatic ON/OFF of different devices connection.
Manual ON/OFF is possible. Regulation is done by installed multi-turn resistors through opening in the case. Visual diagnostic is possible with the help with LED.
1 Automatic mode
The relay turns ON automatically after the engine starts operating and «U ON» is held within 5 seconds. The relay turns OFF after voltage drops lower than «U OFF» and this voltage level is held within 3 seconds.
2 Manual operation
Manual ON/OFF (when the engine is already operating) is done by S switch pressure.
To return to automatic mode turn S switch off and hold «U ON»within 3 seconds.
3. Adjustment
Adjustment may be done during operating of the relay.
Relay operates when U ON>U OFF. At U ON≤U OFF the relay switches OFF and LED burns.
