Discrete LS CHARMs LEDs

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

LS 24 VDC Power
LS DI 24 VDC isolated
LS DI 120 VAC isolated
LS DI 230 VAC isolated
LS DI 24 VDC low-side (dry contact)
LS DI NAMUR
LS DI NAMUR (I.S.)
LS DO 24 VDC
LS DVC HART DTA (simplex and redundant)

Table: Discrete LS CHARMs LEDs
LED color and pattern	Description and corrective action
Green (continuous)	The channel and LS CHARM status is good and the CHARM is configured.
Green (flashing twice per second)	The channel and LS CHARM status is good but the LS CHARM is not configured. If DeltaV Diagnostics displays BAD status for this LS CHARM, a configuration error such as a configuration mismatch, has occurred. If DeltaV Diagnostics displays GOOD status for the LS CHARM, the LS CHARM has not been configured. In this case, configure the LS CHARM in DeltaV Explorer.
Green (flashing ten times per second)	A user has issued an identify LS 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 LS input CHARM, replace the CHARM. If this pattern is seen on an individual LS output CHARM, check that the CHARMs Smart Logic Solver (CSLS) is commissioned and that the LS CHARM is being driven by logic. If this pattern is seen on a group of 12 LS CHARMs, ensure that the correct address plug is installed. If this pattern is seen on all LS CHARMs, ensure that the CSLS is functioning correctly.
Red (flashing twice per second)	Channel fault (open or short circuit) detected or field power missing. Check the wiring and field power. This could also indicate a hardware error in the LS CHARM. Check DeltaV Diagnostics for a hardware error.
Red (flashing ten times per second)	Duplicate address. Check all baseplates for a duplicate address plug.
Green then red flashing three or 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 LS CHARM, replace the LS CHARM. If this pattern is seen on a group of 12 LS CHARMs, ensure that the correct address plug is installed. If this pattern is seen on all LS CHARMs, ensure that the CSLS is functioning correctly.
Green and red alternating two times per second	The LS CHARM is being upgraded or is in upgrade mode.
No colors	The LS CHARM is unpowered or not functioning. If all LS CHARMs' LEDs are not showing a color, check the power connections. If the LEDs on all the LS CHARMs on a baseplate are not showing a color, check the connection to the baseplate. If the LED on one LS CHARM is not showing a color, replace the LS CHARM.
Yellow	This is the channel status indication: Yellow (continuous) - The actual input value or the intended output value is ON. For outputs, yellow continuous indicates the last written output value not the actual readback value. Yellow continuous also indicates that the LS DVC CHARM is driving a 20 mA signal. Off - The actual input value or the intended output value is Off.
