General Information
2.19 — Home
Press the "HOME" button while not editing a field.
This is a typical Homepage. The contents of this page along with the contents of the default left display page (Volts)
were selected such that all the normally desired data would be available for viewing at once.
LINE 1: Oil Pressure (Analog Channel #3) in pounds per square inch followed by Oil Temperature (Analog Channel #1)
in degrees Fahrenheit.
LINE 2: Coolant Temperature (Analog Channel #2) in degrees Fahrenheit.
LINE 3: Battery Voltage in Volts DC.
If any of these signals above are not configured, they will display "n/a" for their value such as the Oil Temperature
shown above.
LINE 4: Often the Fuel Level Sensor (Analog Channel #5) reading in percent. As depicted, Analog Channel #5 is not
configured– leaving the line blank.
2.20 — The Control Panel
The H-100 Control Panel has some inputs and outputs which have been designated to be connected to a standardized
control panel.The format of the control panel will vary from model to model and not all indicators may be present, how-
ever the following signals are always available:
ALARM LED
AUTO/OFF/MAN KEY SWITCH
The alarm LED will flash every second if a new alarm/warning occurs. Once acknowledged via the touch pad or Gen-
Link, the LED will remain lit until the alarm/warning condition goes away. The LED will flash at least once every 30 sec-
onds to indicate the controller is working properly.
The audible alarm will sound when a new alarm/warning occurs. It will be silenced when it is acknowledged.
The key switch in AUTO position allows the system to start automatically, in OFF position prevents the system from
operating, and in MANUAL position runs the generator for test purposes only.
The "NOT IN AUTO" LED will flash every second if the key switch is not in the AUTO position.
The EMERGENCY STOP switch will stop the generator and post an alarm.
2.21 — The Alarm Log
The alarm log is a permanent (nonvolatile) store of the last 20 alarms/warnings/DTCs that occurred. If power is
removed from the controller, the log will be retained. When the alarm log is full and a new fault occurs, the oldest alarm/
warning/DTC will be removed to create space for the new one.
Each alarm/warning/DTC is recorded along with a time/date stamp and up to 6 optional measurements. Two of the six
measurements are fixed (via level 2 security) to be coolant temperature and oil pressure.
The measurements 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. For example you can record the generator voltages, fre-
quency and the state of the transfer switch when an alarm/warning/DTC occurs. The alarm log can be viewed via Gen-
Link or the left hand front panel display. Alarms/warnings/DTCs are displayed by GenLink in chronological order, the
most recent being at the top of the list.
All alarms/warnings/DTCs and sensor failures are recorded in the alarm log.
