Generac H-100 - Manual

3 THE MEASUREMENT "ENGINE" The measurement “engine” is the key feature of the system. All the inputs to the controller are processed by this module. Each physical input is measured and the result processed by an individual set of rules that are set via a PC and GenLink. Normally, a product i...

5 IMMEDIATE = Alarms/Warnings with this qualifica- tion only become active immediately after the engine has started. Sensor Failure Check When this field is set, the input sensor is checked for short circuit or open circuit failure. Normally each of the inputs are conditioned externally to be 4-20mA...

ENGINE MANAGEMENT The engine management module is very similar to that used in the manufacturer's other products. It controls engine cranking, engine starting, engine running and engine stopping. These functions are performed to a set of “rules” that can be customized via parameters from GenLink. In...

Dump Enable — Indicates if extra load dump gov- ernor compensation is desired to reduce increase in frequency caused by drop in load. The following three selections are available: - No Dump — No additional compensation.- Dump — Reset governor algorithm when load dump detected. - Dump & Hold — Sa...

LOCAL TRENDING Local trending is done inside the controller where up to 1000 samples can be stored in memory. GenLink provides an interface to select the analog channels to be trended, the rate to be sampled at, and optional triggers to be used to specify when to sample. Up to 6 analog channels can ...

Generator control is limited to the following output options (referred to as “Hooks”). 1. Use Keyswitch 2. Force Off – cleared with “Use Keyswitch” hook3. Force Manual – cleared with “Use Keyswitch” hook 4. Force Auto – cleared with “Use Keyswitch” hook5. Force Dialout 6. Halt ILC 7. Force Alarm/War...

Press the “ENTER” button. This is a typical System Alarm and Warning page. The n/a indicates there is not an alarm or warning to display on that line. As depicted, this display indi-cates a Fuel Pressure alarm for low pressure. This would be a common alarm for a system that has the gas line turned o...

STATUS There are two System Status pages. These pages show the system status, system time, and system versions. Do the following to view the system status pages: Press the “MENU” button. Press the  button twice. Press the “ENTER” button. This is a typical first System Status page. LINE 1: Engine Ru...

“Warmed Up, Alarms On” Generator is started, warmed up, and the hold-off alarms are enabled. “Running,cooling down” Generator is still running, but waiting for cool down timer to expire. “Stopping” Generator is running down after being turned off normally. “Stopping due to Alrm” Generator is running...

Each line displays a maintenance item that has been set up via GenLink. The value displayed is the approximate % of life remaining before maintenance should be performed. Refer to the Maintenance setup using GenLink. Press the “ENTER” button. This is a typical third Maintenance Status page. Each lin...

This is a typical first Generator Parameter page for a single phase system. LINE 1: Phase titles for the voltage and current – voltage title/current title. LINE 2: Line-to-Line voltage for AB and Line-to- Neutral voltage for A and B in Volts RMS. LINE 3: Neutral current and Line currents in Amps RMS...

The event log, as its name implies, is designed to store events which are programmable from GenLink. Each measurement channel or output function can be set as an event along with a setpoint. For example, if you set Digital Input #1 (the keyswitch in AUTO position) as an event with a setpoint of logi...

COMMUNICATIONS There are 2 ports on the H-100 Control Panel, an RS-232 port and an RS-485. Each port can be recon-figured as to its function, howev...

38 APPENDIX A — ANALOG FUNCTIONS The User Configurable Analog Inputs have several parameters that affect the value interpreted from the A/D reading. In general, the following equation determines the final User Configurable Analog Input result: Result = Scale (Function (Calibrate (Raw A/D read- ing))...
