ENDA EDP2041 is intended for installation in control panels. Make sure that the device is used only for intended purpose. The electrical
connections must be carried out by a qualified staff and must be according to the relevant locally applicable regulations. During an installation,
all of the cables that are connected to the device must be free of electrical power. The device must be protected against inadmissible humidity,
vibrations, severe soiling.Make sure that the operation temperature is not exceeded. The cables should not be close to the power cables or
components.
1) Mains supply cords shall meet the requirements of IEC 60227 or IEC 60245.
2) In accordance with the safety regulations, the power supply switch shall bring the
identification of the relevant instrument and it should be easily accessible by the
operator.

NOTE :
- d.Adr. parameter should be selected C.Pot in master potentiometer. In this case d.Adr. parameter of other potentiometers aren’t used. But be sure that C.Pot isn’t
selected in slave potentiometers to prevent confusion. Settings of slave potentiometers change proportional to setting of master potentiometer. For example; When Max.
output of master potentiometer is changed from 10V to 5V, max. output of slave potentiometers decrease half of previous value proportional to this. If previous output of
slave potentiometer is 6V, it decreases 3V. P.on.c parameter of slave potentiometer should be selected oFF in order to understand master potentiometer when slave is
energized.
- Computer should be used to change only a few potentiometers. In this case, there is not master potentiomer. Output of the required potentiometer is changed
according to d.Adr. parameter.

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.
