> Volts <

This is a typical three phase System Voltages page.

LINE 1: Phase titles for the voltage and current.

LINE 2: Line-to-line voltages in Volts RMS.

LINE 3: Line currents in Amps RMS.

LINE 4: Generator frequency in Hz and total system power in kilowatts.

This is a typical single phase System Voltages page.

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.

LINE 4: Generator frequency in Hz and total system power in kilowatts.

> Switch <

This is the Transfer Switch Mimic Diagram page. It shows the position of the Utility Switch and the Generator Switch. This depicted display shows the Utility switch closed and the Generator switch open. There can be up to 4 HTS switches connected to the generator.

LINE 1: “Transfer Switch Name” indicates which switch inputs are being displayed such as “From HTS #1”. To select a switch to display, select the switch number on the HTS page (refer to the Right Display Pages - Exercise/HTS page). If there are no HTS switches connected, then the Line Power and Generator Power inputs are displayed and the “Transfer Switch Name” is “From Line/Gen Inputs”

LINE 2: Title line showing the left side is the Utility switch and the right side is the Generator switch.

LINE 3: Character graphics showing the switch states – open or closed.

LINE 4: Character graphics indicating the load com- ing off the bottom of the diagram.

> Alrm Log <

This is the System Alarm Log page. It displays the last 20 alarms or warnings that occurred with a time and date stamp. Two records are displayed at a time.

LINE 1/3: The record’s alarm or warning number (lowest number being the most recent) followed by the date and time that the alarm or warning occurred.

LINE 2/4: The alarm or warning description mes- sage. The depicted display shows a basic format in place of the first record and an empty record for the second. The records scroll up at about a 4 second rate.

The message format symbols are explained below:

First 2 characters:

??– Empty slot Wr – Warning

Al – Non-shutdown alarm SD – Shutdown alarm Last 2 Characters:

Sn – Sensor failure

Hi	– Tripped by being greater than threshold
Lo	–	Tripped by being less than threshold
	–	(blank) Internal alarm or warning
