14 questions. Check the box for multiple-choice and true/false. Write on the lines for short answer.
Part A · Multiple choice
The first thing to determine when an ATG alarm comes in is:
- A) Which part to order
- B) Whether the alarm is active now or just history
- C) Who caused it
- D) The weather
A "3.0" line test failure means:
- A) Annual precision test
- B) Periodic precision test
- C) Gross leak category — big problem / high risk
- D) A normal pass
The "0.1" line test is the:
- A) Gross leak test
- B) Annual precision category
- C) Daily test
- D) Pressure setting
To find the correct sensor in the field, you work:
- A) Field → console, by guessing
- B) Console → field, using the Sensor ID, location label, and site map
- C) By opening every sump until you find it
- D) From memory
On a TLS-450PLUS, PLLD line tests are found under:
- A) Menu → Reports
- B) Menu → Diagnostics → PLLD
- C) The Print button only
- D) Setup → Tanks
A High Water alarm means:
- A) Water in a sump
- B) Water in the tank has exceeded the high-water limit
- C) Rain in the spill bucket
- D) The probe is disconnected
Part B · True / False
It's fine to diagnose ATG alarms from the screen only, without going to the field.
True False
A Fuel Alarm means fuel/liquid was detected where it's not allowed (sump, dispenser pan, interstice).
True False
Before running line tests, you should pull the PLLD/line diagnostics history first.
True False
A Setup Data Warning means you should immediately change the console programming yourself.
True False
Part C · Short answer
Write the best-practice ATG workflow (the five steps from the cheat sheet).
Checking slow flow with a gauge at the shear valve — what are the target running pressure, seating pressure, and hold time?
If slow flow affects ALL fueling points on a product, name two likely line- or pump-side causes.
List four things a good site map must include.

Show answer key
- B — Active vs. history: is it happening now?
- C — 3.0 = gross leak category (high risk).
- B — 0.1 = annual precision category (0.2 = periodic).
- B — Console → field: Sensor ID + location label + site map.
- B — Menu → Diagnostics → PLLD (then 0.2 or 3.0 tests).
- B — Tank water has exceeded the high-water limit setting.
- False — Go physical; don't diagnose from the screen only.
- True.
- True — Pull history first, then decide whether to test or inspect.
- False — Don't change programming unless authorized; document and escalate with evidence.
- Screenshot first → verify physically → fix one thing at a time → recheck status → document clearly.
- Running pressure above 25 psi; seating pressure settles above 20 psi; holds seating pressure more than 30 minutes.
- Any two: actual line leak; worn functional element (common on a Red Jacket STP); bad check valve; bad packer o-rings; bad motor or capacitor.
- Any four: tanks (#/product/probe type/notes); lines (line # to dispenser group); sensors (ID + physical location name); emergency stops + what they affect; photos.
