Watson-Marlow 720UN and 720SN User Manual
If Yes is chosen, the pump asks the user whether the remote stop feature is to
be disabled fully (for both manual and auto operation), or only for manual oper-
ation, leaving remote stop functioning when the pump is operating in auto
mode. Choose using the UP and DOWN keys and press ENTER to confirm. If
manual and auto was chosen, the pump briefly displays a confirmation screen
(an example is shown here) and returns the user to the first screen of the Setup
menu. If manual only was chosen, the pump asks the user to make a further
choice, according to whether the pump (with remote control available in auto
mode only) 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 con-
firm. The pump briefly displays a confirmation screen (an example is shown
here) and returns the user to the first screen of the Setup menu.
Note: The confirmation screen indicates whether Remote stop is enabled or dis-
abled, and displays the command sense of the remote control switch even if
Remote stop has been disabled. This allows the command sense to be dis-
played if remote switching is disabled.
Even with the remote stop function disabled, the pump
could still start if the remote auto/manual toggle input
is used to toggle the pump into analogue mode.
Alternatively ...
To toggle the sense of the remote run/stop control between open=stop and
open=run: stop the pump. Turn off the mains power switch at the rear of the
pump.
Hold down the STOP key and the DIRECTION key, and turn on the mains
power switch.
