Use the correct compensating cable.
Do not make any supplement to cables. Connect
the thermocouple cables to the right places at the
input terminal.

For PT100 Sensorresistance ( ) :
When using 2-wire PT100 sensor, as shown in the
figures, make 8 and 9 terminals short circuit for
ET4420, ET7420 and ET9420 devices, make 10 and 11

Controllers are intended for installation in

control panels. Make sure that the device is
used only for intended purpose.

The shielding must be grounded on the instrument side.
During an installation all of the cables that are connected to
t h e d e v i c e m u s t b e f r e e o f e n e r g y.
Device must be protected against inadmissible humidity,
vibrations, severe soiling and make sure that the operation
temperature is not exceeded. All input and output lines that
are not connected to the supply network must be laid out as
shielded and twisted cables. These cables should not be
close to the power cables or components. The installation
and electrical connections must be carried on by a qualified
staff and must be according to the relevant locally applicable
regulations.

1) While panel mounting, additional distance

required for connection cables should be

2.MODBUS ERROR MESSAGES

Modbus protocol has two types error, communication error and operating error. Reason of the communication error is
data corruption in transmission. Parity and CRC control should be done to prevent communication error. Receiver side
checks parity and CRC of the data. If they are wrong, the message will be ignored. If format of the data is true but
function doesn’t perform for any reason, operating error occurs. Slave realizes error and sends error message. Most
significant bit of function is changed '1' to indicate error in error message by slave. Error code is sent in data section.
Master realizes error type via this message.
