In addition, the purge unit combines the eluent streams from the pump heads.
Tip: You may open the purge valve (by turning the valve knob counterclockwise) to
reduce the system pressure. However, if you are operating an ISO-3100BM,
observe the precautions on page 90.
2.10 Leak Sensor
A leak sensor is installed inside the pump. If liquid collects in the drip tray under the fluid
connections, the leak sensor reports a leak. The
Status LED on the front panel door
changes to red, a beep sounds, and a message appears on the pump display and in the
Chromeleon Audit Trail.
When the leak sensor reports a leak, eliminate the cause for the leakage and dry the leak
sensor (

page 124).
Leak detection is enabled as a standard when the pump is shipped. For more information, see
section 5.5.8 (
