Running:
After initialization is complete, the LEDs have the following meanings: At power up, LEDs 2
through 6 are turned ON then OFF in sequence.

K1
Relay K1: ON = Energized
K2
Relay K2: ON = Energized
K3
Relay K3: ON = Energized
K4
Relay K4: ON = Energized
Note 1: If this input is defined, every three seconds the LED is pulsed to its opposite state for 0.1
seconds, otherwise, the LED is off.
