Page 2: Introduction
Introduction The RGK400SA and RGK420SA controllers implement state-of-the-art functions for use with manual control (stand-alone) generating sets. The RGK400SA incorporates front panel buttons for switching the controller on and off and starting and stopping the generator. On the RGK420SA, this function is performed by a key switch on the front panel. -
Page 3: Display Indications
To set up these functions, see the P01 – Utility menu. Switching on and starting up (RGK400SA) To switch on the controller when battery power is present at the terminals, press and hold the STOP button for 1 seconds. The device switches on and performs a self-test. -
Page 4: Expandability
Thanks to its expansion bus, the RGK4...SA can be expanded with additional modules of the EXP... series. The RGK400SA and RGK420SA support the EXP1040 expansion module, which provides additional 2 inputs and outputs. Program at least one of the resources which the module will make available (for instance, assign the analog input AIN2 to fuel level). -
Page 5: Parameter Setting From Smartphone Or Tablet Via Wi-Fi
Parameter setting from smartphone or tablet via Wi-Fi It is possible to establish a wireless connection to the RGK4..SA using the LOVATO Electric SAM1 app, available for Android or iOS tablets and smartphones, and the CX02 accessory. The app can be used to view alarms, send commands, read measurements, set parameters, download events and send collected data via e-mail. -
