Pin assignment
Start:
Start signal. A measurement is started by closing (edge)
the
Start
and
DGnd
inputs.
Stop:
Stop signal. A running measurement will be stopped if 0V
are applied (open collector).
Ready:
Ready signal. Applied to (0V) if the device is ready for
measurement (open collector).
Error:
Error signal. Applied to (0V) if a device error (e.g. leakage)
exists (open collector).
Wait
1
:
Wait signal. Indicates that the detector is ready to measure
and waits for a start signal. This signal can be used to trig-
ger an autosanmpler to inject a sample.
Lumi:
High Luminescence signal: This signal is active in case a
high luminescence state is detected (if enabled in the sys-
tem settings. A high luminescence usually indicates mixing
problems (in case of liquid scintillation method) or a light
leak due to improper tubing.
Aux Out
Auxiliary output. Can be controlled through the controller
software.
Aux in
Auxiliary input. An external status signal can be monitored
at tis port. Status is available though the controller soft-
ware.
