1. Verify wiring between TAC I/A Series MicroNet Sensor and controller is installed
according to job wiring diagram and national and local wiring codes.
Note: Wiring of the S-Link and MicroNet LONWORKS network between the sensor and the
controller is not polarity sensitive.
2. If controller is part of a MicroNet L
ONWORKS network, verify the TP/FT-10 LONWORKS
network wiring between controller and other devices is installed according to job wiring
diagram and national and local electrical codes.
3. Verify 24 Vac power is provided from a Class 2 power transformer and wiring is installed
according to job wiring diagrams and national and local electrical codes.
4. If multiple devices are powered from the same transformer, verify wiring polarity has
been maintained between all connected devices (24H connected to 24H and 24G
connected to 24G).
5. If multiple devices are powered from a common transformer, verify all issues associated
with powering multiple devices from a common transformer have been addressed.
Note: For more information, refer to EN-206, Guidelines for Powering Multiple Full-Wave
and Half-Wave Rectifier Devices from a Common Transformer, F-26363.
6. Verify digital outputs are wired according to job wiring diagram and national and local
electrical codes.
7. Make certain current requirements of the controlled device do not exceed rating of
controller’s digital outputs.

1. Verify controlled equipment is in a manually controlled, safe state.
2. Place controller power breaker in the ON position. See job wiring diagrams.
3. Observe green Data Transmission LED (Figure-10) and do the following:
a. If green Data Transmission LED is steady on or blinking, go to step 4.
b. If green Data Transmission LED is off, check power.
4. Observe red Service LED (Figure-10) and do the following:
a. If the red Service LED is off or flashing, proceed with downloading an application
using WorkPlace Tech Tool and configuring the controller with a third party network
management tool. Refer to WorkPlace Tech Tool 4.0 Engineering Guide, F-27254,
for details on downloading applications.
b. If red Service LED is steady on, turn power to controller OFF, wait five seconds, and
turn power ON. If red Service LED is still steady on, turn power OFF and replace
controller.
