34903 not switching with alarm in BenchLink

Using BenchLink data logger 3, v4.3 with 34970A, 34902A, 34907A, 34903A.

I have BenchLink configured to monitor temperature with 34902A.  I want to actuate a switch on the 34903A to break the enable line going to a motor if the temperature gets above a certain limit.  The temperature channel is configured to test for High Only and I selected the appropriate channel in the 34903A to close if the alarm triggers.  I have the enable line connected to the normally closed side of the switch.  

When attempting to verify this configuration is working I successfully get the alarm to trigger and is shown on the display, however, the switch does not actuate cutting power to the motor.  I can manually actuate the switch either at the front panel or through BenchLink Switch Control to cut power...just not automatically using the high limit alarm.

Help would be appreciated.
