turned automatically) and choose
the chemical curve assigned to the switch. See Section 6.4.1 for more information
on chemical curves and chemical curve parameters.

bration parameters. Select

For the electrical properties of the two output signals, see Section 3.3.3, "Connecting
the Indicating transmitter".
process stops (as indicated by contact closure).The wash is
repeated when the process restarts (if the stop lasts over
60 seconds). The signal is on hold between washes.When
used with an external independent timer, contact closure
holds the output signal.
Switch closure prevents wash cycle. It can be used to pre-
vent wash action when the process pipe is empty. The mes-
sage will appear when a wash cycle is initiated.
WASH STOP
At switch closure the system waits for an external wash
command before initiating wash.
Any chemical curve and associated field calibration scale
can be selected by switch closure. The scales assigned to
each switch independently.
Contact closure prevents access to calibration and config-
uration ("external password"). Can be used to seal the cal-
ibration.
