For example, you can connect a flow sensor on a sample pipe to one of
the TTL inputs. If the sample stops flowing, the sensor signals the TTL
and the system bypasses that sample stream.
Configuring TTL Input Responses (Actions) in Chromeleon 7 PA
Refer to the Chromeleon 7 PA Help for details about how to configure
analyzers.
•
When a relay output is configured to change states with an alarm
event, do not configure it in an instrument method to control devices.
•
Always include a command that opens (turns off) the relay at the
beginning of the instrument method (see
page 49 ). Include the
command in all methods that are used with the system.
3.9 Liquid Level Sensor (Option)
The optional Liquid Level Sensor Kit
(P/N 068563) provides a sensor that signals
when the level of liquid in a reservoir
reaches the sensor. For example, the sensor
can be installed on a waste container to
signal when the container is almost full or on
a standards or mobile phase reservoir to
signal when the reservoir is almost empty.
The sensor status is displayed on the SP
ePanel in Chromeleon 7.
Figure 3-30. Liquid Level Sensor Installed
Up to four sensors can be connected to the SP. For installation instructions, see
Appendix F .
When liquid level sensors are connected, they are enabled on the Sensors page in
the Chromeleon 7 Instrument Configuration Manager.
