Watson-Marlow 520DuN IP66/NEMA 4X User Manual 48
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.
