ALr 38 – How the 'Run – Lockout Time' alarm works
When the SCS Controller has not been connected to an application within the configured Run – Lockout Time period, the controller turns off all outputs and triggers an ALr 38 alarm (sometimes called a “Shutdown alarm”).
What happened?
- The controller has not been connected to an SCS application within the 'Run – Lockout Time' period. As a result, the controller has turned off all outputs.
- Connect to the controller using any SCS application (such as Field or Track) to reset the timer and restart normal operation, OR
- If an application connection is not immediately available, restart the controller for a temporary grace period by entering a PIN code via the keypad.
There are two actions available. Either:
- Connect to the controller using any SCS application (such as Field or Track) to reset the timer and restart normal operation, OR
- Restart the controller for a temporary grace period (if an application connection is not immediately available) by entering a PIN code via the keypad.
Note: The keypad PIN entry starts the Grace – Lockout Time countdown. If the controller is not connected to an application before the grace period expires, an ALr 39 alarm will be triggered, and all outputs will be turned off again. For more detail, see how the 'Grace Time – Lockout Time' alarm works.
When the SCS Controller has not been connected to an application within the configured Run – Lockout Time period, the controller turns off all outputs and triggers an ALr 38 alarm.
