External Trip Input

Terminal J4-16 is available for connection to a normally closed thermostat or overload

 

relay in all operating modes as shown in Figure 3-35. The thermostat or overload relay

 

should be a dry contact type with no power available from the contact. If the motor

 

thermostat or overload relay activates, the control will automatically shut down and give

 

an External Trip fault. The optional relay (CR1) shown provides the isolation required

 

and the N.O. contact is open when power is applied to the relay and the motor is cold. If

 

the motor thermostat is tripped, CR1 is de-energized and the N.O. contact closes.

 

Connect the External Trip Input wires (N.O. relay contact) to J4-16 and J4-17. Do not

 

place these wires in the same conduit as the motor power leads.

 

To activate the External Trip input, the External Trip parameter in the Level 2 Protection

 

Block must be set to “ON”.
