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, Test Passed appears on the screen. • If the test fails, Test Failed appears on the screen. 3. To exit the test, press Enter. 4. Repeat steps 1 through 3 for the remaining switch terminals (S2 through S4). 5.
5.3.7 Performing the Sparge Valves Test This test identifies whether a malfunctioning sparge line is due to electronics or sparge-valve failure. Perform this test if you do not see any bubbles when the 600E system sparges eluents. 1. Press Enter.
2. Open the reference valve to release pressure in the system, or allow pressure to decay to zero. 3. Flush the 600E pump with an eluent that is miscible with methanol (used in step 7). To remove any buffers, flush with water, followed by methanol.
