ATTENTION!
If either error or Trip occurs in the Transparent mode, the Control Unit (UC) will not automatically Switch
Off its outputs. Protections must be programmed by the user with the error or Trip bits in the Ladder
logic of the Control Unit (UC).
5.4.2.1 Connection Diagram – Transparent Mode
shows an example of the use of the Control Unit (UC) on the Transparent
operation mode with drive through the digital inputs at 24 Vdc, where on the Ladder programming digital input
I11 turns the motor on/off, digital input I12 is used as a Check Back signal and digital output O1 drives the motor.

5.4.3 Overload Relay
In this operation mode the Control Unit (UC) presents operation characteristics similar to an Overload Relay, using
one NO (normally open) digital output and another NC (normally closed). The other digital outputs can be used
according to the user’s needs.
