DATA
NX8BIT CRCH CRCL T
The T times corresponds to a time in which data must not be exchanged on the
communication bus to allow the connected devices to recognize the end of one
message and the beginning of another. This time must be at least 3.5 characters
at the selected baud rate. Adress range (1-247) is address of the connected
device. The data field contains data sent to the slave by master or data sent to
master by slave.
CRC is a error check method by using MODBUS RTU protocol and consists of 2
bytes.
Available Modbus Function:
Read Hold (03) function is used for reading measured values and set value. If any
request of reading of a register, excepted mentioned in register table, device will
send an error message.
For example to read phase1 voltage by sending a message to the device.

Below measurement and application can be implemented with
EPM-04/04C/04CS.
1) Phase currents (IL), Neutral current (IN), Phase-Phase and Phase-Neutral
voltages can be measured .
2)
Existence of live phases can be observed by L1-L2-L3 LEDs on the device.
3) Min. and max. values for measured currents and voltages can be monitored
with only one button.
4) Max. demand values for measured current can be monitored, demand
time can be defined in dE tý menu.
5)
A 4 digit password can be defined from pin menu in order to prevent the
change of settings by unauthorized person.
6) Current transformer ratio is programmable. (1 .... 2000)
Current transformer ratio can be programmed in term of turn number
between 1.....20 (for CT-25 adapted devices).
Voltage transformer ratio is programmable. (0.1 .... 4000)
7) A user defined measurement range is used for monitoring the voltages
and currents; and Out1 & Out2 outputs are used for warning the user and
disconnecting the device in case of exceeding the limits of measurement
range.
8) In case of using the device for measuring the current values of motors etc.,
start delay (AUto rSt) function can be used for preventing the equipment
against the improper tripping, which is because of the demurrage current.
9) When a failure has occured use the Latch function, in order to keep the
device with saving its position (Latched), even if the failure conditions are
removed.
7th, 8th and 9th subjects are valid for EPM-04C/04CS.
