Analog Output
One programmable analog output is provided at J4-10 and J4-9. The output
is scaled 0 - 5 VDC, 0 - 10 VDC, 4-20mA or 0-20mA. The output function is
programmed in the Level 1 Output block, Analog Out parameter value. The
scaling of the output is programmed in the Level 1 Output block, Analog
Scale.
Relay Outputs
One normally open (N.O.) and one normally closed (N.C.) relay contact is
available at terminals J4-1, J4-2 and J4-3. J4-2 is relay common. The output
is programmable in the Level 1 Output block, Relay Output parameter.

External Trip Input
Terminal J4-17 is available for connection to a normally closed thermostat or
overload relay in some operating modes as shown in Figure 3-9. 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. The N.O.
contact is closed when power is applied to the relay and the motor is cold.
Connect the external trip input wires to J4-17 and J4-18. 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".
3-14 Receiving and Installation
Connect the N.O. contact to another circuit by attaching the wires to J4-1
and J4-2.
Connect the N.C. contact to another circuit by attaching the wires to J4-3
and J4-2.
