CIRCUTOR EDMk Series - Manual (Page 2)

6.5. Communications description
One or more EDMk meters can be connected to a computer or PLC. As well as the usual operation of each piece of
equipment, this system may centralize data at one single point. The EDMk has an RS-485 series communications
output. If more than one analyzer is connected to one RS-485 communication bus, it is necessary to assign to each a
peripheral address (from 01 to 255) so that the remote computer or PLC sends data on different measured or calculated
recordings to those addresses. The RS-485 connection is made with woven mesh shielded communications cables,
with a minimum of three wires and with a maximum distance between remote computer and the last analyzer of 1.200
metres. This RS-485 series bus can connect up to a maximum of 32 devices.The EDMk meter communicates using the
MODBUS RTU© protocol (Pulling Question / Answer).
7. DISPLAY / LEDS
- L1 -, L2 - and L3 - shows that the device has measured voltage in each phase. If one of these does not exist, the corresponding identifi cation number does not
appear. The symbols appearing behind each phase (L) indicate the direction of the current in the current transformers, showing if the point of measurement
is consuming or generating energy (
L1 , L2 and L3 fl ashing, informs of possible errors of connection of current transformers).
- T1 , T2 y T3 (identifi cation only available on the EDM3k; shows the tariff selected for that time, independently from the tariff displayed on the upper
section.
- The
symbol indicates that load is inductive. The symbol indicates a capacitive load.
- The symbol shows that the meter is the fi rst and fourth quadrant (consumption). The symbol indicates that the meter is in the second and third
quadrant (generation).

TYPE MC3
The EDMk energy meter display is divided into two sections: the fi rst of these (on the upper section) displays the value of the energy meters (Active energy and Inductive
reactive energy or Capacitive). The second shows the measurement, in real time, being taken by the meter at that time.
CPU CPU led indicates that the device is working right fl ashing in one second intervals.
COMM COMM led fl ashes quickly in varible intervals when the device is receiving or sending information throught is RS-485 port.
