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.
