Installing a manual injector 3-5
Connecting to the column or column heater
To connect the manual injector to the column or column heater:
Tip:
Ensure you have already installed the manual injector as described in the
instructions included with the manual injector:
1. Prime the pump, purging the injector (see the instructions appropriate
for your data control system in Chapter 4 ).
2. Connect the free end of the manual injector outlet tubing to the column
or column heater.
Connecting the inject start signal (for manual injector)
For 1500-series pumps with an optional 1500-series manual injector or
FlexInject dual manual injector, you make an inject-start output signal
connection from the I/O terminal block, on the pump, to the appropriate
inputs on the detector.
This section describes the connections for Waters 2489 and 2414 Detectors.
For a description of signal connections to other model detectors, refer to the
detector’s operator’s guide.
Required materials
• Two-wire cable from the manual injector
• Screwdriver, small, flat-blade
To make the inject start signal connection from the pump to the detector:
1. Remove the terminal block from the rear of the pump.
2. Insert the red stripped wire into position 1 of the terminal block, then
tighten the screw to secure the wire.
3. Insert the black stripped wire into position 2 of the terminal block, then
tighten the screw to secure the wire.
4. Firmly push the terminal into the back of the pump.
5. Remove the terminal block from connector A on the back of the detector
(see the figure “Inject start connection to a 2489 detector” on page 3-7
and the figure “Inject-start connection to a 2414 detector” on page 3-8 ,
depending on which model detector you have).
