2GENSYS 2.0 CORE
2.1 Description
The GENSYS 2.0 CORE can control a single or a multiple generating sets power plant. You can combine this
module with one RDM 2.0 remote display.
GENSYS 2.0 CORE can be connected to the RDM 2.0
GENSYS 2.0 CORE is a Generator management module
Several power plants possibilities
Same motherboard as the GENSYS 2.0 product family
GENSYS 2.0 CORE is able to perform all GENSYS 2.0 features.
GENSYS 2.0 CORE can be controlled using different ways:
Connected to a RDM 2.0 remote display module.
Remotely using your favorite Internet Web browser and by using digital inputs programmed
to be used as AUTO/ MAN, START/STOP, OPEN/CLOSE GENERATOR BREAKER, OPEN/CLOSE
MAINS BREAKER buttons.
2.2 User interface with a RDM 2.0
The RDM 2.0 is a remote display module that is connected through Ethernet to the GENSYS 2.0 CORE. This
way GENSYS 2.0 CORE can be easily controlled and set up in the same way as a GENSYS 2.0 module.
Please refer to the RDM 2.0 technical documentation “A53 Y0 9 0020 x En- Technical documentation” to
connect your GENSYS 2.0 CORE to a RDM 2.0.
2.3 User interface using digital inputs
According to your application, some digital inputs can be used to simulate the control panel buttons of a
GENSYS 2.0. You have to select the following input functions to simulate the button.
