3.8 Powering of the FL4000
After connecting to a 24 VDC power source, the unit will go through a power up delay of
approximately 15 seconds. The LEDs will blink in alternating red – green sequence, the unit will
output an analog signal of 0mA (3.5 mA with HART) and the fault relay will be in the de-
energized state. If the unit is configured with relays energized, the relays will de-energize for
approximately 0.5 seconds. Upon completion of the power on sequence, the green LED will
alternate - on for 5 seconds and off for 0.5 seconds to indicate a READY status.
