General Information

H-100 Control Panel Technical Manual

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 logical one, each time the keyswitch is set in the auto position, an event will be logged. Similarly you can set an analog event with an analog setpoint and a comparison type. For example you can set an event if the oil pressure is less than 10 psi or if power output is greater than 100 kW.

Each event is recorded along with a time/date stamp and up to 6 optional measurements. The measure- ments you want to record are selected from a pull down list in GenLink using the alarm/event log menu. They can be analog inputs, digital inputs or output functions. The event log can only be displayed via GenLink, it cannot be viewed on the front panel. Events are displayed by GenLink in chronological order, the most recent being at the top of the list.

MAINTENANCE SETTINGS

The controller provides a mechanism to generate multiple warnings based on maintenance intervals. Normally it will be shipped with these warnings turned off. GenLink is used to enable these warn- ings by setting a maintenance interval for the alarm of choice. The interval can be in engine run hours, a specific engine run hour, number of operations, a specific date or a combination of two of these meth- ods. For example you can set the interval associated with oil life to 6 months or 100 engine hours (which- ever occurs first). The transfer switch is one example of where a number of operations is relevant, spark plug life is not.

•To disable a maintenance warning, set the “mainte- nance cycle” field to N/A.

•To set a specific date, set the “installed at” setting to the current date then set “End of life” to the specific date.

•To set a number of operations, set the “installed at” setting to zero then set “End of life” to the number of operations required.

•To set a specific operation number (say at opera- tion 500), set the “installed at” setting to the cur- rent number of operations, then set “End of life” to the operation number.

•To set a number of engine run hours, set the “installed at” setting to zero then set “End of life” to the number of engine hours required.

•NEVER set the “Installed at” hours to anything other than zero.

A warning is generated when the maintenance cri- teria are met. This warning can be cancelled by the acknowledge button but will re-occur after 15 min- utes. To permanently cancel the warning you must reset the maintenance interval. This can only be done via GenLink. The audible alarm will NOT sound for each 15 minute re-occurrence of the warning after the first maintenance warning is acknowledged.

The front panel display will show the percentage of life left for each possible maintenance item.

AIR/FUEL RATIO CONTROL (OPTION)

With the addition of an oxygen sensor and a solenoid to control the air fuel mix, the H-100 Control Panel can perform air/fuel ratio control to provide an opti- mum (stochiometric) mix to reduce emissions. This feature can be turned on or off via GenLink. The air fuel solenoid output pin shares its function with the preheat output. You must choose one of the two func- tions as follows:

•To select air/fuel - set the “Diesel y/n” setting on the governor page to “No”. Set preheat to “No”

•To select preheat - set the “Diesel y/n” setting on the governor page to “Y”. Set preheat to “Y”

I2T CURRENT MONITORING (OPTION)

Optionally the H-100 Control Panel can apply pre- dictive firmware modeling to give I2T protection for the rotor and stator assembly. Based on parameters entered into the H-100 Control Panel via GenLink, the firmware models the temperature rise and fall of the alternator assembly and limits operation to prevent it being damaged. The entered parameters basically describe the thermal properties of each alternator to the firmware. GenLink allows you to choose the alternator model, and this automatically downloads the appropriate parameters. The H-100 Control Panel will normally be delivered prepro- grammed with the appropriate data . GenLink will allow you turn this feature on or off as desired. There is a GenLink display of the allowable temperature limits for the selected alternator (2 limits, one for the stator and one for the rotor) and also a display of the predicted temperatures.
