Front Panel

The front panel of the liquid handler contains a Start button, Stop button, LED display, and power indicator light.

Start Button

The Start button can be used to home the XYZ-arm when the liquid handler is first powered up or when the motors for the XYZ-arm have been relaxed. When pressed, the yellow LED lights.

Stop Button

The Stop button is a large touch-sensitive pad that can be used to terminate a program and stop the liquid handler from responding to any more commands coming from the running program. This button also relaxes the motors for the XYZ-arm so that you can easily lift the probe and move the arm. When pressed, the yellow LED light is turned off.

In a situation where an emergency stop is required, pressing the Stop button immediately stops the liquid handler. The Stop button is designed to be sensitive enough that if you just brush it with your hand it activates.

LED Display

The 8-character LED display shows the current status of the liquid handler and any error codes as they are encountered. Your program can also contain instructions for showing 8-character messages on the display when the program is run.

Refer to Section 5, Troubleshooting for a list of current error codes and required actions.

Power Indicator Light

This indicator becomes lit when you turn on power to the liquid handler using the power switch located on the rear panel. Refer to the rear panel diagram on page 2-16if necessary.
