Connecting a fraction collector

See your fraction collector's accompanying documentation for complete
Tip:
information on the product.
This section explains how to make electrical connections when the Waters
fraction collector is part of the Prep system.
Position the fraction collector on the system's left, close to the detector.
Tip:

Making the remote start connection

Fraction collectors need a signal from the injector to indicate when a
separation method begins. A cable carries this signal between the remote start
input on the fraction collector and the Inject and Gnd terminals on the
controller. Use a standard signal cable (Startup Kit) to connect the remote
start terminal on the fraction collector to the controller.
To make the remote start connection:
1. Connect the fraction collector's pin 3 to any vacant Gnd terminal on the
controller.
2. Connect the fraction collector's pin 4 to the Inject terminal on the
controller.

Making chart mark connections

The fraction collector outputs to a detector's chart mark input to indicate tube
changing during a separation.
Connect the fraction collector to the detector's chart mark input with a
standard signal cable (Startup Kit). The fraction collector outputs a signal
from terminals 9 and 10 of its I/O connector at every tube change.
To make chart mark connections:
1. Connect pins 9 and 10 on the collector to the appropriate input terminals
on the detector. Here are two examples:
• Connect to the Mark +/– terminals on the Waters 2487 or 2414
Detector.
• Connect to any available Event In and Gnd terminals on the Waters
490 Detector.
