System Operation
5.3.6 Program Mode’s Alarm Table
The Alarm Table displays the alarms programmed within the method. This table can be viewed by pressing
the Alarm instrument key while in Program mode or by pressing the Alarm softkey on the Method List
screen. When an alarm occurs the alarm status light will turn on, the Alarm instrument light will flash, and a
beeper will sound. The first key pressed when an alarm occurs will not have it’s normal effect but will
instead simply cancel the alarm. As an option the method can be placed on Hold when an alarm occurs.
When a method is held, the run timer stops counting but the pump continues to pump the current buffer. All
other instruments continue to operate during this time as well. Holds last until the user “Continues” the run.
For more information about holding a run see section 5.4.2.2. The units used for the alarms are either time
(minutes) or volume (ml) depending upon the choice made when the method was created. Table 22
describes how to program the Alarm Table.
Table 22.
Program Mode’s Alarm Table
Reference Description
Alarm Table: Each alarm in a method is shown in a scrolling list
format. The selected alarm is shown with an arrow (>) pointing
to the alarm. Use the Prev and Next keys to move the selec-
tion up and down the list.
When the selected alarm is already programmed, the softkeys
are as shown in the top picture; and when the selected alarm is
not already programmed, the softkeys are as shown in the bot-
tom picture. The table consists of 2 columns: the alarm time or
volume and the Hold choice made for the alarm.
Up to 3 alarms can be programmed in a method, and the units
will be either time (minutes) or volume (ml), depending upon the
choice made when the method was created. Alarms do not
have to be entered in the order in which they will occur. The
next time the Alarm Table is viewed, the alarms will be
rearranged in order of occurrence.
