MIWII units have been designed and verified using the most advanced and reliable equipment. Mounting and testing
automation ensure a high consistency of the final product. Before sending a unit back to the factory, we strongly
recommend you follow the recommendations below.

Even if it will not always solve the problem, at least they will help define it better for a quicker repair.

If you need to send a unit back to the factory for repair, please use the appropriate RETURN MATERIAL
AUTHORISATION process, and follow the shipping instructions provided by our Service Department, especially in the
case of international shipments. This will lead to a faster and efficient solution of your problem.

CATEGORY

SYMPTOM

POSSIBLE CAUSE

RECOMMENDED ACTION

PROTECTION

The relay does not trip

- Element not enabled
- Output not assigned
- Inappropriate setting group

-Set the element permission to ENABLE
-Program the output to the desired element

using ENERVISTA MII SETUP-SETPOINT-
RELAY CONFIGURATION

- Make sure that desired group is active

(group 1 or group 2) and/or that there is no
settings group change input that could
modify the active group

GENERAL

When feeding the unit, no
indicator is light up

- Insufficient power supply
- Fused fuse
- Loose fuse
- Incorrect wiring

- Verify the voltage level using a multimeter

in the power supply terminals, and check
that it is within the model range.

- Remove the power supply board and

replace the fuse.

COMMUNICATIONS

The relay does not
communicate via the front
RS232 port

- Incorrect cable
- Damaged cable
- Relay or PC not grounded
- Incorrect baud rate, port, address,

etc

- Make sure you are using a straight cable.
- Replace the cable
- Ensure ground connection
- Make sure that the communication

parameters in the computer match the
ones in the relay.

The relay does not
communicate via the
RS485 port

- Relay or PC not grounded
- Incorrect polarity
- Incorrect baud rate, address etc

- Ensure ground connection
- Invert polarity
- Test other baud rate, etc
