The description and functions of the control buttons on the module panel are as follows:
1) Stop/Reset Button – This button places the module into its stop/reset mode. This will clear any alarm conditions for
which the triggering criteria have been removed. The fuel supply will be removed and if the engine is running, it will be
brought to a stand still.
2) Manual Mode Button – This mode is used to allow manual control of the generator functions. Once in manual mode
the module will respond to the Start button (5) and start the engine.
3) Auto Mode Button – This button places the module into its “automatic” mode. The module will monitor the remote start
input and once a start condition is signaled the set will be automatically started and placed on load. If the starting
signal is removed the module will automatically shut off the engine after a cooling down delay timer is satisfied.
4) Test Mode Button – This mode allows the operator to perform an “on load” test of the system. Once in test mode, the
module will respond to the start button (5) and start the engine and run on load (for further details please see the more
description of “test operation” in the generator set manual).
5) Start Button – This button is only active in “manual” or “test mode”. Pressing this button in manual or test mode will
start the engine and run off load (manual) or on load (test).
6) LCD Display – To view or monitor all the system operating parameters by the user.
7) Scroll Button – This button is used to display the different instrumentation values (power, voltage, current, frequency,
etc.) on the LCD display. Pressing this button repeatedly will scroll through each individual instrument eventually
returning to the original instrument displayed.
8) Configure/Log Button – This button is used to view shutdown alarm history. The module maintains a log of the last 15
shutdown alarms. The alarm is logged, along with the date and time of the event and shown on the LCD display.
Pressing this button together with the “stop” button (1) will enter the user in configuration mode (for further details on
configuration mode, please see “configuration editor” in the generator manual).
