Watson & Sons 520DUN user manual Remote stop

18.11 Remote stop

The 520DuN pump can be started and stopped with a remote switch between the 5V terminal and the i/p terminal of the Run/stop input, using an open=run or open=stop command sense. It also operates with a logic input between 5V and 24V on the i/p terminal of the Run/stop input. Disabling the remote stop control does not disable other remote controls.

￿In the third screen of the Setup menu select Remote stop using the UP and DOWN keys. Press ENTER to confirm your choice.

￿The pump displays a screen allowing the user to disable the remote stop fea- ture. Use the UP and DOWN keys to choose Yes or No and press ENTER to confirm the decision.

￿If No is chosen, the pump asks the user to make a further choice, according to whether the pump is required to run on an open or closed remote switch: Open=stop or Open=run. Choose using the UP and DOWN keys and press ENTER to confirm. The pump briefly displays a confirmation screen (an exam- ple is shown here) and returns the user to the third screen of the Setup menu.
