Identification

Serial number is used to identify the version of EP010 and the Modbus Device wich can be
connected to it.
Serial Number (S/N) has the following format:
Where "RR" (two digits) is the version of EP010, while "G" (one character) is related to the
connectable Modbus device. Value of G for each device type is reported in the relevant chapter
of the device-dependent section of this manual.
Important: at the end of start-up, the WD LED flashes at 0.5 Hz a number of times that's
device dependent. This way, the type of device that can be connected to an EP010 unit can be
immediately identified in field.

Product specification

2.8.1 Start-up

At power up or after a reset, beginning with all the LEDs switched OFF, a diagnostic process
starts and the following sequence is performed:
Then all LEDs stay ON for about 500 ms. After this time:
1 all the LEDs are switched OFF
2 the WD LED flashes a number of times depending on the device that can be connected
on the Modbus port
3 the EP010 enters the Run state.
