3. Enter two timed events (or edit existing events). In the first event,
turn on the TTL1 output. In the second event, turn off the TTL1
output.
In the example in Figure 38, a 1 is entered in the TTL1 output field at
2.00 minutes to turn on the TTL, and a 0 is entered at 14.00 minutes
to turn off the TTL.

Monitoring Eluent Generator Cartridge Use (Dionex
RFC-30 Only)
The Dionex Reagent-Free Controller monitors eluent generator cartridge
use and displays warning messages when the cartridge ion count nears
depletion. A warning first appear when the percentage of ions left reaches
10%. Warnings are repeated at each 1% decrease in count. To set up this
feature:
•
When you install a new cartridge, set the cartridge ion count to 100%.
As the cartridge is used, the Dionex RFC decrements the percentage.
•
If you remove a partially used cartridge, note the percentage of ions
remaining. Then, if you later reinstall the cartridge, re-enter the
percentage.
