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.

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.

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.
