(3)Time (Exercise Period Days): The generator is automatically started at a

(4)Manual Start – The generator can be manually started by selecting ON from SET GENERATOR directory under the GENERATOR MODE menu. In manual mode, the generator MUST be manually switched OFF by selecting OFF from the SET GENERATOR menu item.
GENERATOR STARTING AND STOPPING CONFIGURATIONS
Two different generator start routines are available to allow use with a wider variety of generator types. The sequence of closing and opening of the RY7 relay changes depending upon what position the underlining cursor is in from the SET RY7 FUNCTION menu item under the GEN STARTING DETAILS
(13)menu item. The choices are GLOWSTOP or RUN.
When RUN is selected as the function of the RY7 relay, the RY7 COM and RY7 N.O. contacts remain closed while the generator is running. This is usually wired to the ignition system of the generator engine and/or a fuel solenoid valve. The normally closed contacts of this relay are also available on the terminal block, marked RY7 N.C. The normally closed contact is open (not connected to the common terminal) while the generator is running. When the generator is off, the RY7 N.C. terminal is connected to the RY7 COM terminal. This configuration is useful for starting many HONDA brand generators as well as some others. This should also be used to select when the RY7 COM and RY7 N.O. contacts are used to control a two wire (auto crank) type generator.
When GLOWSTOP is selected as the function of the RY7 relay, the RY7 COM and RY7 N.O. contacts remain open while the generator is running. The contacts close only when it is time for the generator to be stopped. This is useful for generators that require a stop signal to shut down the generator. The GLOWSTOP configuration is useful for starting ONAN brand generators.
The GLOWSTOP setting can also be used for diesel generators. The RY7 COM and RY7 N.O. contacts will be closed during the PRE CRANK SECONDS period. This relay can be used to provide both the GLOW and STOP signals. When this is done the generator will be given both GLOW and STOP signals before cranking and when stopping. This is done on many diesel generators by their own starting systems. You should also check that the control system also powers the glow plugs during the cranking signal - the generator manufacturer or dealer can provide more information.
The terminals RY8 COM and RY8 N.O. provide contacts that remain closed only during the generator- cranking period. This is usually wired to the starter solenoid (relay) of the generator engine. This relay closes after an initial PRE CRANK delay period (the default MAX CRANKING SECONDS period is 10 seconds). Relay RY8 will open after a
The generator will be stopped when the battery charger has kept the temperature compensated battery voltage near the BULK VOLTS DC setting for the ABSORPTION TIME period.
When it is time to stop the generator, relay RY7 will open or close (depending on which RY7 FUNCTION is selected), stopping the generator. This will occur after a 40 second cool down period. If the generator does not stop, the inverter will continue to charge the battery at the FLOAT VOLTS DC.
The transfer from generator to inverter will be less noticeable if you manually turn off the generator from the inverter’s Control Panel instead of from the generator’s off switch. This allows the inverter to first disconnect the generator before it is turned off, reducing problems with voltage sags during the transition.
