Display indications
Navigating the display pages
 Press the ▼button to scroll through the left indicator measurements. The following measurements are displayed in rotation:
o Mean phase-to-phase voltage
o Phase-to-phase voltages
o Phase-to-neutral voltages
 Press the ▲button to scroll through the right indicator measurements. The following measurements are displayed in rotation:
o Frequency
o Current
o Power output
o Fuel level (if enabled)
o Oil pressure (if enabled)
o Engine temperature (if enabled)
o Battery voltage
 The numeric indicator at the bottom of the display normally shows engine working hours, but pressing the ▲button switches it to RPM display.
 Certain measurements may not be displayed, depending on controller setup and connections to the generating set.
 The user can specify a default configuration, in which the display appears when the controller is powered on and to which it returns if no buttons are pressed for a given time.
 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.
The model and revision number appear on the display.
 With the controller switched on but before the motor is started, the pressure/temperature/battery charging icons indicate the state of the corresponding sensors.
 To start the engine, press the START button for 1 second. The controller runs the engine start procedure but makes only one start attempt. If this attempt fails and you wish to try
again, press the START button again.
 To stop the engine, press the STOP button for 1 second. The controller performs an engine cooling cycle (if required) and then runs the engine stop procedure.
 To switch off the controller, press and hold the STOP button for 3 seconds. The engine is stopped, then the controller switches off. If an engine cooling cycle is needed, the
controller only switches off at the end of this, after the engine has stopped. During the cooling cycle, the display reads out a countdown of the time to engine shutdown. If you
wish to stop the engine immediately, press the STOP button again during the cooling cycle.
 If the remote starting input is used, closing its circuit to ground switches on the controller and starts the engine, making multiple attempts if necessary.
 Opening the circuit stops the engine and switches off the controller, leaving it a state of zero battery consumption.
Switching on and starting up (RGK420SA)
 To switch on the controller when battery power is present at the terminals, turn the key switch to the ON position. The device switches on and performs a self-test. The model
and revision number appear on the display.
 With the controller switched on but before the motor is started, the pressure/temperature/battery charging icons indicate the state of the corresponding sensors.
 To start the engine, press the START button for 1 second. The controller runs the engine start procedure but makes only one start attempt. If this attempt fails and you wish to try
again, press the START button again.
 To stop the engine, turn the key switch back to the OFF position. The controller performs an engine cooling cycle (if required) and then runs the engine stop procedure.
The controller switches off at the end of the engine stop procedure.
 The remote start input is disabled when the key switch is in OFF or ON position.
 With the key switch in REM position (even with the key removed), starting and stopping via the remote input is enabled. Closing the remote starting circuit to ground switches on
the controller and starts the engine, making multiple attempts if necessary.
 Opening the remote starting circuit, stops the engine and switches off the controller, leaving it a state of zero battery consumption.

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).
 To install the module, proceed as shown in the figure, with the controller switched off:
 The next time the controller is switched on, it automatically recognises the expansion module and makes the new resources available.
Inputs and outputs
 The inputs and outputs are identified by a code and a sequential number. For example, the digital inputs are named INPx, where x is the input number. Similarly, the digital
outputs are named OUTx.
 The input/output numbering is a sequential numbering from the top down.
CODE DESCRIPTION BASE EXP
INPx Digital inputs
1…6
7...8
OUTx Digital outputs
1…5
6…7
User alarms (UAx)
 The user can define up to 2 programmable alarms (UA1…UA2).
 The following can be established for each alarm:
o the source, i.e. the condition that generates the alarm;
o the text of the message that appears on the display when the alarm condition occurs;
o the properties of the alarm (as for standard alarms), i.e. how it interacts with the genset controller.
 If the alarm is displayed following activation of an external digital input, then the source must be an INPx.
 The user can define a freely programmable message to appear on the display.
 Properties for user alarms can be defined using the same method applied to normal alarms. In other words, users can decide whether a given alarm must stop the engine,
sound the siren, activate the generic alarm output etc. See the Alarm chapter.
 Multiple simultaneous alarms are displayed in sequence.
 Use the specific command in the Commands menu to reset a programmed alarm with memory.
 See the settings menu to define alarms.
IR programming port
 The parameters of the RGK4...SA may be configured via the front panel optical port using the IR-USB CX01 programming dongle or the IR-Wi-Fi CX02 dongle.
 Simply insert the connectors of the CX... dongle in the sockets of the port on the front panel to obtain mutual recognition of the devices, indicated by the green LINK LED lighting
on the programming dongle.
USB CX01 and Wi-Fi CX02 programming dongles
Setting parameters from a PC
 Xpress configuration and control software can be used to transfer setup parameters (previously set) from the RGK4...SA to a PC hard disk and vice versa.
 Parameter transfer from a PC to the RGK4...SA may be partial, i.e. only the parameters of specified menus will be transferred.

Doc: I470GB10_16.docx 18/10/2016 p. 5 / 19
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.
Parameter setting from a smartphone or tablet via NFC
 The LOVATO Electric NFC app for Android devices (smartphones and tablets) lets you program parameters in a simple and intuitive way, with no need for connection cables.
This method even works with the RGK4...SA switched off.
 Preprogrammed parameters can be transmitted to the RGK4...SA controller simply by resting a smart device on the front panel.
 Pre-requisites for functioning:
o The smart device must support NFC protocol and the NFC function must be active and not locked.
o If the RGK4...SA is switched on, the genset engine must be stopped.
o If an advanced password is set (see P03.03), this must be known, or access will not be possible.
o It is best to have the app pre-loaded on the smart device. If it is not, proceed to the next step anyway.
You will be routed automatically to the on-line store's installation site.
o Rest the smart device on the front panel of the RGK4..SA controller, more or less in the position shown alongside.
Hold it in position for a few seconds until you hear a beep. The app runs automatically and the parameters are loaded and
displayed.
o Parameter menus are accessed and parameters changed in exactly the same way as for the other apps described
previously.
o Make all the changes you need then press the Send button and hold the smart device in touch with the front panel of the
RGK4...SA controller again.
The new parameters are transferred to the RGK4...SA controller. A reset is required to make
them active. This operation is shown by the NFC wording appearing on the display of the RGK4...SA controller.
Automatic acquisition of rpm/W ratio
 To acquire this ratio, the W signal must be connected and rated engine speed must be set in the setup menu.
 With the engine running at normal speed, press and hold the START and ▲buttons.
 Wait a few seconds until the RPM appears on the display, then release the buttons.
 The W/RPM ratio is calculated and memorised.
