The screen¶
Power-up and status lines¶
On power-up the panel runs a self-test (CATERPILLAR, then the nameplate) and then shows a status line matching whatever the set is doing:
STOPPED · READY · START DELAY · CRANKING · WARM UP · COOLDOWN · STOPPING
The mode sits in the top right corner on every one of them.
Running pages¶
While the set is running, the screen cycles five pages every 5 seconds. Click a page to see it on a simulated screen, using example readings.
| Page | Top line | Bottom line |
|---|---|---|
| 1 | ON LINE / RUNNING, and the mode | kW, volts, hertz |
| 2 | Volts, amps, hertz | kW, power factor, load percent |
| 3 | Rpm, oil pressure | Coolant temperature, battery volts |
| 4 | Fuel percent, fuel burn in gph | Engine run hours |
| 5 | Line-to-line and line-to-neutral volts | Current on each of the three phases |
The per-phase currents on page 5 are deliberately slightly unequal: a real set never sits perfectly balanced.
What interrupts the cycle¶
- An unacknowledged warning takes a slot in the rotation and shows its text.
- A shutdown takes the whole screen, blinking in reverse video, alternating between the fault name and its code.
