The Front Panel Display; Left Display; Right Display - Generac Power Systems H-100 Operation Manual

General Information
The I/O scan time of the ILC is about 100 ms worst case. This means that all inputs and outputs are scanned within 100
ms. Also, the ILC processes one rung every 5 ms, so 5 rungs will take 25 ms. However, this is in parallel with the IO
scan and not added to it.
The offline tool uses graphic symbols to design the "rungs" of the ladder logic. The rungs are simple and can only have
2 combinatorial elements in them, but by the use of "soft contacts" the output of one rung can be fed into the input of
another to provide more combinations. As well as the logical combinations, there are also analog comparisons, count-
ers and timers available for use in the rungs. As an example this allows the following type of logic to be built:
IF (in automatic) AND (engine running) AND (air temperature > 25 deg) FOR (20 seconds) THEN OPERATE (output
7).
Generator control is limited to the following output options (referred to as "Hooks").
1. Use Key Switch
2. Force Off – Cleared with "Use Key switch" Hook
3. Force Manual – Cleared with "Use Key switch" Hook
4. Force Auto – Cleared with "Use Key switch" Hook
5. Force Dial Out

2.12 — The Front Panel Display
The front panel display consists of two LCD displays that are 4 rows of 20 characters each and a key pad with seven
buttons and two LEDs.
2.12.1— Left Display
The left display is used to display a "fixed" set of parameter pages and has no cursor or entry fields. The key pad has
no direct control of its contents. Its contents are determined by a menu selection on the right display.
2.12.2— Right Display Pages
The right display has several pages and responds directly to the key pad. There are two "quick" buttons on the key pad
that are used to go directly to either the Homepage or the Menu page. The Enter button is used to enter and exit edit
mode, operate an output override, or select another page. When not in edit mode, the arrow buttons are used to navi-
gate around the page to either an edit field or a control field. When in edit mode, the up/down buttons slew up or down
through the available values and the right/left buttons are used to change to a different digit or edit field. Moving off an
edit field while in edit mode automatically enters the value displayed. Also, while in edit mode, pressing the Home but-
ton will return the parameter to the last value entered.
