Learn Process
Each line must be learned before the FMS system can continuously monitor it. Learning involves bleeding the line
pressure down to zero, with no air in the line, then introducing a calibrated leak, facilitated by 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) or the TS-550evo FMS Programming Guide (p/n 000-2173). 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.
When to Learn / 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 LS-500 to another 4-20mA channel

Procedure
1. The needle valve kit (TS-ALNIP) and 3.0 GPH Leak Generator (TSP-ALCAL) should be installed in the STP
manifold. The line must be purged of all air prior to learning the line.
2. Open the needle valve with the leak generator in an approved container to catch any product. Let the line
pressure bleed down to 0. Make sure that the pressure reads 0 on the pressure gauge installed on the needle
valve kit.
3. Navigate to the line control screen on either the touch screen or by the web page. Locate the learn section and
press start.
4. If the learn process is performed correctly the screen will show the events in the following sequence,
• Learning zero offset
• Turn the STP on
• Learn pump pressure
• Learn the pressure decay curve
