Alert Displays

FUSE – Station and MV/PS output alarm

The TMC-424E features built-in circuit protection to help prevent damage to the controller caused by an over-current condition on any output terminal. If the controller detects an overload condition, it will bypass the affected output and display the word FUSE with the affected station number identifier(s). All remaining stations will operate as programmed for automatic operation.

If the condition occurs on the Pump Start/ Master Valve circuit, all stations using the master valve will prompt the FUSE message.

To clear the warning, press any button. The controller will continue to operate as scheduled and will attempt to run all stations as programmed.

IMPORTANT: Clearing the display does not correct the problem. The controller will retry the affected station(s) at each programmed watering cycle and bypass the affected station(s) until the problem is corrected.

Before continuing to operate the controller, identify and correct the source of the problem. In most cases, the FUSE alert condition is caused by a faulty valve solenoid, pump start relay and/or shorted wire splice.
