General Information
page also selects the switch to use for the Left Display Switch Mimic diagram if that switch is enabled. In addition, it is the selected switch number for the pre- vious page, and for the remote annunciator lights for generator power and line power. The right side of the first line is the enable state of the HTS. It is editable and can have the following values:
“Disabled”
This HTS switch is not included in the system.
“Enabled”
This HTS switch is included in the system.
NOTE:
Enabling a switch that is not present will result in a switch communications warning after a few seconds and will switch the display to the Alarms page.

The alarm LED will flash every second if a new alarm occurs. Once this alarm is acknowledged via the touch pad or GenLink, the LED will remain lit until the alarm condition goes away. The LED will flash at least once every 30 seconds to indicate the controller is working properly.
The audible alarm will sound when a new alarm occurs. It will be silenced when it is acknowledged.
The keyswitch in AUTO position allows the system to start automatically, in OFF position prevents the sys- tem from operating, and in MANUAL position runs the generator for test purposes only.
The “NOT IN AUTO” LED will flash every second if the keyswitch is not in the AUTO position.
The EMERGENCY STOP switch will stop the genera- tor and post an alarm.
This is a typical Home page. 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.

THE ALARM LOG
The alarm log is a permanent (non volatile) store of the last 20 alarms that occurred. If power is removed from the controller, the log will be retained. When the alarm log is full and a new alarm occurs, the oldest alarm will be removed to create space for the new one.
Each alarm is recorded along with a time/date stamp and up to 6 optional measurements. Two of the six measurements are fixed (via password protection) 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, frequency and the state of the transfer switch when an alarm occurs. The alarm log can be viewed via GenLink or the left hand front panel display. Alarms are displayed by GenLink in chronological order, the most recent being at the top of the list.
All alarms/warnings and sensor failures are recorded in the alarm log.
THE EVENT LOG
The event log is similar to the alarm log except that the data is stored in temporary memory (volatile) and will be lost if power is removed. The event log has space to hold up to 20 events. When the event log is full and a new event occurs, the oldest event will be removed to create space for the new one.
