Edit
Provides the means to edit five of the operating parameters of
the unit: Exercise Time, Current Time, Frequency, Language,
Startup Delay, and Reset Maintenance. To access the editing
screens go to the Edit menu and press the “Enter” button. One
of the above menus will appear. Use the UP and DOWN triangle
buttons to move from menu to menu. When you are in the
menu you want to change press the “Enter” button. Then use
the UP and DOWN triangle buttons to change the value. When
you have reached the value you want press the “Enter” button.
If you want to get out of a choice without changing it simply
press the “Esc” button.
•Exercise Time will go through 4 selections: Quiet Test Mode
(Yes/No), Select Hour, Select Minute, and Select Day. When
you are through the unit will be programmed to perform a
weekly exercise.
•Current Time will go through 5 selections: Select Hour,
Select Minute, Select Month, Select Date, Select Year.
The current time must be set to enable the exercise and
maintenance functions of the panel.
•Frequency is not enabled at this time.
•Language provides three choices; English, Francais, and
Espanol.
•Startup Delay provides a way to change the time delay
between when Utility fails and when the Generator starts and
transfers. It is adjustable from 10 to 30 seconds.
•Reset Maintenance will reset the Maintenance warning
clock.
Debug
Provides four test tools integral to the control panel: Inputs,
Outputs, Display, and QT-Test.
•TEST Inputs provides a way to see the status of the 8 input
channels that the control panel monitors. See Table 8 for
the list of inputs the control panel monitors. Each input
represents an open or closed set of contacts, and will
display either a 0 or 1 character. The 0 character represents
an open contact; a 1 character represents a closed contact.
The Inputs screen is a handy way to tell if the control is
seeing a valid input from a particular source.
•TEST Output provides a way to see the status or the output
relays the control panel uses to make things happen (like
crank and run and transfer). See Table 8 for the list of
output channels. Each channel represents a relay with a
character of either 0 or 1. The 0 character represents a
relay that is de-energized (OFF); a 1 represents a relay that
is energized (ON). The outputs screen is a handy way to tell
if the control is telling the generator to start, or transfer, etc.
•Display provides two flashing bars that test the display
LEDs. As the bars flash on and off you can readily tell if the
display has a bad area; if an area does not turn on it means
those LEDs are not working. The control panel would
require replacement to correct a bad display.
•QT-Test is only available on the 17-20kW units. It provides a
way to test the Quiet Test mode of the generator. When tested
the generator will run at a lower RPM during the test. Note that
for the unit to perform an actual weekly Quiet Test Exercise, it
must be enabled in the Exercise Time editing menu.
