CONFIGURATION
When the LVOS is first powered the STATUS LED will blink three times. See table below for additional blink patterns. In Design
Center, click the Configure Stations button on the toolbar. The Status LED will have a 5 blink pattern and the load LEDs will blink.
With the LVOS highlighted in Design Center, press one of the load buttons on the front of the station three times to configure. The
station may also be configured by typing the serial number in the project file, configuring when the system is programmed.

1. The station must always be configured and programmed to the system in order to perform a firmware update.

PLACING STATION IN BOOT CODE
If the application code is corrupted it may not be possible for Design Center to connect to the LVOS PWM station to update. If this
condition is suspected, place the LVOS PWM station into boot code and then update following the steps above.
1. Remove HV power to the station.
2. Press and hold PWM buttons 2 and 3 while HV power is restored.
3. All of the station’s load and status LED lights will flash in unison.
4. While in this mode attempt the regular firmware update steps 2-4 again. (Above - Firmware Upgradable From Design Center)
5. When the firmware update is finished the update dialog box will display a green checkmark and the station will reboot
automatically.
