General Information

Analog Outputs

External Trip Input

External or remote motor
overload protection may be
required by National Electrical
Code or equivalent.
3-30 Installation
Two programmable analog outputs are provided on J1A-6 and J1A-7. These outputs are
scaled 10 VDC (1mA maximum output current) and can be used to provide real-time
status of various control conditions. The output conditions are defined in Section 4 of this
manual.
The return for these outputs is J1A-1 analog ground. Each output is programmed in the
Level 1 Output block.
1. Connect the Output #1 wires to J1A-6 and J1A-1.
2. Connect the Output #2 wires to J1A-7 and J1A-1.
Terminal J1B-16 is available for connection to a normally closed thermostat or overload
relay contact in all operating modes as shown in Figure 3-17. 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 (opens the J1B-16 connection) the control will
automatically shut down and give an External Trip fault.
Connect the External Trip Input wires to J1B-16 and GND
power supply for the opto inputs. Do not place these wires in the same conduit as the
motor power leads.
To activate the External Trip input, the Level 2 Protection block, External Trip parameter
must be set to "ON".
