Learn Process
Each line must be learned before the FMS system can continuously monitor it. Learning involves
bleeding the line pressure to zero, with no air in the line, then introducing a calibrated leak, using
the leak generating kit (TS-ALCAL). The system learns this pressure decay curve and uses it to
compare test data during continuous operation to determine if there is a leak in the line.
NOTE:
All console programming must be completed prior to the learn process. Refer to the
Setup (Console Programming) chapter in this manual for details. Administrator privileges are
necessary to Learn Lines. Refer to T5 Series FMS Programming Guide (p/n 000-2142), the EVO
TM
550 and EVO
TM
5000 FMS Programming Guide (p/n 000-2173), or the EVO
TM
600 and EVO
TM
6000
Programming Guide(p/n 228180061) for information on gaining Administrator privileges.
NOTE: Complete the Pre-Operation Line Testing chapter prior to starting the Learn Process.
NOTE: No dispensing can take place during the Learn Process. If product is dispensed while
Learning, stop the process by pressing the Stop button.
NOTE:
DO NOT submerse or block the TS-ALCAL orifice while learning the line. The orifice MUST
be kept free of dirt and debris.
NOTE
: For T5 Series, learned line leak and monitoring data is stored in the 4-20 mA module.
For EVO
TM
600 and EVO
TM
6000, learned line leak and monitoring data is stored in the Controller
Module.
When to learn or re-learn
• Line installation and start-up
• After repairs or modifications that effect the operating or holding pressure of the line
• After 4-20mA Input Module replacement
• After certain 4-20mA Input Module firmware upgrades (consult FFS Technical Services
Department)
• If moving the TS-LS500 to another 4-20mA channel
