This, together with the panel graphics, aids in troubleshooting the system. Floatswitches can be raised individually and checked against the indications.

The output for an external alarm light has two discrete indications: two quick flashes followed by a pause indicates high wetwell level, single flashes indicate floatswitch malfunctions. Reset is automatic when the condition is cleared. For testing the alarm light, one double-flash of the alarm light output occurs on powerup. Flash timing is designed with a 25% duty cycle to extend lamp life.
