4. How to operate
(1) Operating sequence for digital speed controller
Step 1) Supply DC +24V power to the battery terminals (E (-), F (+)) of the controller.
Step 2) Configure parameter values required for selection of the engine type and control of the
engine.
Step 3) Install the controller on the generator system and complete circuit wiring.
Step 4) The controller will activate the actuator with power supply and pick-up sensor input.
(2) Detailed operating sequence
Step 1) Supply DC +24 V power to the battery terminals (E (-), F (+)) of the controller.
Power supply to the controller can be done by direct connection to the battery or power sup-
ply controlled by external control devices. Fuses (15 A/24V) are required for power supply to
the controller through the terminal.
When the controller displays Low Battery Fault message, you need to charge the battery or
replace it with the one having normal voltage before starting the controller.
Step 2) Configure parameter values required for selection of the engine type and control of the
engine.
There are 3 ways to configure parameters required for the controller:
1. Using default setup
2. Designating the engine type in Engine Type menu
3. Configuring each parameter in System setup menu
For more information, see Chapter 3. Configuration and Operation.
Step 3) Install the controller on the generator system and complete circuit wiring.
Once the configuration is completed, the controller will be in Stand By condition preparing to
receive input information from pick-up sensor and surrounding terminals and operate.
Step 4) The controller will activate the actuator with power supply and pick-up sensor input. When
the power is supplied and the pick-up terminal delivers normal sensor inputs as the engine
starts, the controller activate the actuator.
