Readiness/Function Code
The TLS-450PLUS ISD software shall store a code upon first completing a full diagnostic check of all monitored
components and systems. This is applicable when the ISD feature is initially setup or when power is restored.
The TLS will store a readiness code following power-up and once a day at the ISD test time until the ISD feature is
fully operational (ready). There are five fields that make up the Result Code, ABCDE, defined below.
ISD equipment self-tests Field:
A - ISD feature setup test. Failing this test indicates one or more ISD setup parameters are incorrect.
B - ISD data streams performance test. Failing this test indicates that there is either:
•
One or more ISD sensor-out alarms.
•
One or more data streams have been missing for a 24 hour period.
ISD tests:
C - Collection Gross A/L (or Flow Performance) – All hoses
D - Containment Gross Over Pressure & Vapor Leakage
E - Vapor Processor – All vapor processor tests
Result Codes by Priority:
P – Pass
F – Fail
N – No Test
Standard ISD test codes that represent multiple devices (e.g. collection tests on all hoses) are the combined
individual test results (e.g. any test with an ‘F’ result yields a combined tests result of ‘F’, etc., so that a combined
‘P’ only results when all tests are ‘P’).
The Readiness code is reported on every power up. If any of the results do not pass (‘P’), the Readiness code is
updated daily, until all tests pass.
TLS-450PLUS ISD is considered ready once all five readiness code parameters report pass (‘P’), at which point a
readiness code is no longer recorded until triggered by the next power up event.
The readiness code is available via the ISD Monthly Report - printout if queued in the most recent 10 events:

Descriptions should support readiness code conditions, prioritized left to right.
