Discrete CHARMs LEDs

The following table describes the meaning of the colors and patterns associated with the two LEDs on the discrete CHARMs:

DI NAMUR CHARM
DI 24 VDC isolated CHARM
DI 120 VAC isolated CHARM
DI 120 VAC isolated Plus CHARM
DI 230 VAC isolated CHARM
DI 24 VDC low-side sense (dry contact) CHARM
DO 24 VDC high-side CHARM
DO 24 VDC isolated CHARM
DO 100 mA energy limited CHARM
DO VAC isolated CHARM
I.S. DI NAMUR CHARM
I.S. DO 45 mA CHARM

Table: Discrete CHARMs LEDs
LED color and pattern	Description and corrective action
Green (continuous)	The channel and CHARM status is good and the CHARM is configured.
Green (flashing twice per second)	The CHARM is not configured. If DeltaV Diagnostics displays BAD status for this CHARM, a configuration error such as a configuration mismatch, has occurred. If DeltaV Diagnostics displays GOOD status for the CHARM, the CHARM has not been configured. In this case, configure the CHARM in DeltaV Explorer.
Green (flashing ten times per second)	A user has issued an identify CHARM command from the DeltaV Diagnostics application. This is not a fault and no action is required.
Red (continuous)	No communications on the bus or no address. If this pattern is seen on an individual CHARM, replace the CHARM. If this pattern is seen on a group of 12 CHARMs, ensure that the correct address plug is installed. If this pattern is seen on all CHARMs, ensure that the CHARM I/O card is functioning correctly. If this pattern is seen on all CHARMs, the CIOC could be in simulate mode. If the CIOC is in simulate mode, no corrective action is required.
Red (continuous)	The connectors on the CHARM Column Extenders are crossed.
Red (flashing twice per second)	Channel fault. Check wiring and associated field device. If wiring and device are correct, replace the CHARM.
Red (flashing ten times per second)	Duplicate address. Check all CHARMs baseplates for a duplicate address plug.
Green then red flashing four times per second	A CHARM fault (such as a bad address or a faulty CHARM bus) exists that does not affect the channel status. If this pattern is seen on an individual CHARM, replace the CHARM. If this pattern is seen on a group of 12 CHARMs, ensure that the correct address plug is installed. If this pattern is seen on all CHARMs, ensure that the CHARM I/O card is functioning correctly.
Green and red alternating two times per second	The CHARM is being upgraded or is in upgrade mode.
Green then red flashing briefly once every 1.5 seconds (for output CHARMs only)	The CIOC has placed the CHARM in a fault state.
No colors	The CHARM is unpowered or not functioning. If all CHARMs' LEDs have no color, check the power connections. If the LEDs on all the CHARMs on a baseplate have no color, check the connection to the baseplate. If the LED on one CHARM has no color, replace the CHARM.
Yellow	This is the channel state indication: Yellow (continuous)-The actual input value or the intended output value is ON. Off-The actual input value or the intended output value is OFF.
