Select this option to set the targe t temperature of the
refrigeration system. The sampler will operate the cooling or
heating systems as needed to maintain this target temperature.
1. Select the REFRIGERATION option and press Enter.
2. Use the Number buttons to set the target temperature as
degrees Celsius. Press Enter to save the setting.
3. Single Bottle Only — Select YES to enable the Quick
Cool mode, NO to disable it.
Quick Cool lowers the target temperature for the first 24
hours. This feature can be useful for drawing down the
temperature quickly when collecting warm liquids or
larger sample volumes. It is optimized to quickly cool
hourly 250 ml, 22 °C samples.
Smaller or cooler samples may be susceptible to freezing if
the Quick Cool option is turned on.
Select this option to configure the four alarm outputs. An alarm
output is based one of the following events:
• PROGRAM STARTED – This event occurs when the
Start Time is met. For programs using NO DELAY TO
START, this will occur immediately when you press the
Run button. The alarm output signal lasts three
seconds.
• PROGRAM COMPLETED – This event occurs when a
running sampling program has finished. This alarm
output stays on as long as the run time display reads
PROGRAM COMPLETED.
• PUMP ERROR– This event occurs when the sampler has
detected a pump failure or an absence of liquid. If this is
a true pump failure (pump is jammed), manual
intervention is required before the sampling program
can resume. For all other pump errors, the alarm output
stays on until the pump is successfully operated or
liquid is again present.
• DISTRIBUTOR JAMMED – This event occurs when the
sampler has detected a distributor failure. This
condition must be corrected before the sampling
program can resume. This alarm output stays on until
the distributor is successfully operated.
• 3-WAY VALVE CONTROL – This event occurs whenever a
sample is initiated and controls the optional Three-way
Valve. For more information about the optional
Three-way valve option contact your Isco dealer or the
Teledyne Isco factory.
• TAKING SAMPLE – This event occurs each time a sample
is taken. The alarm output stays on until the sample
event is completed.
