A CEM+ with a SmartLink power board is powering a SmartLink button station. When I press any button on the station, however, no LED indicator light appears on the button and no preset is activated in my Sensor + rack.
This communication issue may be the result of one or more problems detailed below.
SmartLink Power Board
If the SmartLink power board in the Sensor + rack is not functioning properly, station communication will not work.
When unplugging and plugging in a station you should see flashing green indicator lights or a color chase on the buttons depending on the age of the SmartLink station.
Please carefully check the voltage between the pins listed below:
- Pin 1 and ground = between 18 to 21 volts
- Pin 2 and ground = between -18 to -21 volts
- Pin 1 and Pin 2 = between 36 and 42 volts
Dip switches (located at S1) should be pushed up (ON) to enable station power.
The CEM+ must already have presets recorded in order for the SmartLink stations to trigger them. Going to Group > Presets > Activate Preset, try to activate a preset # that corresponds to the button station you are troubleshooting. If such a preset does not exist this is your issue.
If a preset is activated from the CEM+ and the station(s):
A) Display an LED indicator light on the button associated to that preset
-Check polarity on the station wiring
B) Do not display any LED indicator light on the button associated to that preset
- Check the dip switch settings on the back of the station.
- You may have bad station hardware or bad station wiring. Contact ETC Technical Support for further assistance.
