2-10 Setting Up the Detector
The following table describes the detector I/O connections.
Generating inject start
To generate the inject start function on the detector at the start of an injection
from the Alliance Separations Module, make the connections shown in the
following table and figure.
Detector analog-out/event-in connections
Signal
connections
Description
Inject start Activates timed events by triggering the run-time clock
to start.
Lamp off When the input is enabled, the lamps is turned off. The
lamp can only be turned on by sending a new method to
the detector, using the lamp button, or rebooting the
detector.
Chart mark Adds a chart mark (at 10% of full scale) to either or
both analog output channels (Signal Out 1 and Signal
Out 2) and is configurable.
Auto zero Calculates an offset value that, when added to the
sample signal, makes the resulting baseline signal
zero.
Analog 1 and
Analog 2
Method programmable analog output.
Minimum output voltage range: –0.1 to 2.1 VDC
For sample rates of 10, 20, 40, or 80 Hz, this output
runs at the selected data rate.
For sample rates of 1, 2, or 5 Hz, this output runs at 10
Hz.
Switch 1 Controls a timed event or threshold level and is a
user-programmable auxiliary output.
Switch 2 Controls a timed event or threshold level and is a
user-programmable auxiliary output.
