Performing 600 Controller Extended Test Routines 99
5.3.2 Performing the Stop Flow Test
The Stop Flow switch accepts a signal from an external device that stops the pump. This
test verifies that the Stop Flow input switch is functioning.
1. Attach a jumper wire from the Stop Flow terminal to the Gnd terminal on the 600
controller rear panel (see Figure 5-2).
2. Press Enter.
• If the test is successful, Got Stop Flow appears on the screen.
• If the test fails, Did Not Get Stop Flow appears on the screen.
3. To exit the Stop Flow test, press Enter.
4. Remove the jumper wire.
5. Press Enter to proceed to the next test.
5.3.3 Performing the External Inject Test
The Inject screw terminal accepts a signal from the external injector (manual or
autosampler) to start a run. This test verifies that the associated inject switch is
functioning.
1. Attach a jumper wire from the Inject terminal to the Gnd terminal on the 600
controller rear panel (see Figure 5-2).
2. Press Enter.
• If the test is successful, Got INJECT appears on the screen.
• If the test fails, Did Not Get INJECT appears on the screen.
3. To exit the test, press Enter.
4. Remove the jumper wire.
5. Press Enter to proceed to the next test.
