CONNECTINGPOWER
The G307K2 requires a 24 VDC ±20% power supply. Please take care
to observe the following points:
- The wire used to connect the operator interface’s power supply
should be at least 22-gage wire. If a longer cable run is used, a
heavier gage wire should be used. The routing of the cable should
be kept away from large contactors, inverters, and other devices
which may generate significant electrical noise.
- A power supply with a Class 2 or SELV rating is to be used. A Class
2 or SELV power supply provides isolation to accessible circuits
from hazardous voltage levels generated by a mains power supply
due to single faults. SELV is an acronym for “safety extra-low
voltage.” Safety extra-low voltage circuits shall exhibit voltages
safe to touch both under normal operating conditions and after a
single fault, such as a breakdown of a layer of basic insulation or
after the failure of a single component has occurred.
The G307K2 has three serial ports, as well as an Ethernet port. The
serial ports are exposed via one DB9 male connector, and one DB9
female connector. You may assign one unique protocol to each of the
ports for a total of three different serial protocols.
Note: If you assign a protocol to the Programming Port, you will no longer
be able to download. You should create a means to call the
StopSystem() function from the HMI touchscreen, such that the
Programming Port activity can be halted on command. Alternatively, the
HMI's memory can be cleared to restore download functionality.
The Ethernet port can be programmed to communicate via four
protocols simultaneously. For more information on protocol support,
please refer to the Crimson 3 programming software.
PCCONNECTION
Configuration files are downloaded to the Kadet 2 via the PC port, which
can be connected to a computer via various cables.
