Bio-Rad BioLogic LP System - Manual (Page 83)

5.4 RUN MODE
Run mode is used to carry out the sequence of actions which are programmed within the current method.
The name of the current method which can be run is shown on the top line of the LCD in Manual mode and
on the main menu of Program mode. To run a method which is not the current method, see section 5.3
Programming Mode, and section 5.3.1 Programming Mode’s Main Menu. The following sections describe
starting runs, runs in progress, and interpreting the chart recorder trace.
5.4.1 Starting a Run
To start the Run Mode press the Run mode key. When entering Run mode, an internal system check is
made to make certain that all of the required valves are connected and that all run parameters are valid.
Section 5.4.1.1 describes the possible errors and how to resolve them and allow the method to be run.
Table 24 describes the Run Mode.
Note: The internal check before each run cannot determine if a fraction collector or chart recorder are con-
nected and will assume that they are connected. To avoid problems, check these components before start-
ing a run.

Reference Description
Countdown screen: When entering Run mode, the start of the
run is delayed 10 seconds to provide the opportunity to set the
Multirun and Delay features. The current status of these fea-
tures is shown on line 2 of the LCD.
The Multirun setting is always set to 1 when entering Run
mode. The Delay setting is remembered between runs so it is
important to check this setting. When the Multirun or Delay
softkeys are pressed the countdown is stopped while editing the
appropriate parameter.
After the parameter is set, the countdown timer is reset to 10
seconds and begins counting again. The run automatically
starts when the countdown expires.
•
Multirun: This allows number of runs to be set or changed.
• Delay: This allows the Delay to be set or changed.
• Cancel: This cancels the run and places the BioLogic LP in
Manual mode with the Pump instrument active.
• Start Now: This bypasses the countdown and starts the run
immediately.
Note: When entering Run mode, if you do not want to use multi-
ple runs and you are certain that the delay setting is correct,
pressing the Run mode key two times will bypass the count-
down exactly like pressing the Start Now softkey.
