Figure 6.9
Arrival to Switch 1’s sensor selection menu, sensor A selected
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.
3
WASH STOP
Switch closure prevents wash cycle. It can be used to pre-
vent wash action when the process pipe is empty. The mes-
sage
WASH STOP
will appear when a wash cycle is initiated.
4
REMOTE WASH
At switch closure the system waits for an external wash
command before initiating wash.
5
SCALE SELECT
Any chemical curve and associated field calibration scale
can be selected by switch closure. The scales assigned to
each switch independently.
6
CALIBRATION SEAL
Contact closure prevents access to calibration and config-
uration ("external password"). Can be used to seal the cal-
ibration.
7. If you chose Scale select as switch function, return to the Switch menu (if not re-
turned automatically) and choose
3 SCALE CHEMICAL
to enter the parameters for
the chemical curve assigned to the switch. See Section 6.4.1 for more information
on chemical curves and chemical curve parameters.
8. If necessary, the chemical curve assigned to a switch can be adjusted by field cali-
bration parameters. Select
4 SCALE FIELD
in the Switch menu to enter the parame-
ters.See Section 6.4.3 for more information on field calibration and field calibra-
tion parameters.
6.3.3 Configuring mA outputs
For the electrical properties of the two output signals, see Section 3.3.3, “Connecting
the Indicating transmitter”.
