COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
8.2 LEDs “LINE” and “24VDC”
The two LEDs “LINE” and “24VDC” indicate the status of the main power supply (LINE) and auxiliary power supply
(24VDC).
LINE 24VDC LINE 24VDC
<50V X OFF X
>50V and < VDC BUS MIN X FLASH X
>VDC BUS MIN X ON X
X <~16V X OFF
X >~16V and <20,4 X FLASH
X >21,4 X ON
X = Not consistent
If the main power supply LINE is inferior to VDC BUS MIN, the driver is disabled.
If the auxiliary power supply 24VDC is inferior to 20,4V, the driver might not operate correctly.
8.3 LEDs “FLT” and “STS”
FLT and STS are LEDs indicating the driver general status.
FLT (fault) consists of a red LED, while STS (status) consists of an orange LED and a green LED.
Status FLT STS
Hardware error or critical firmware ON Seq. Seq.
Driver retrievable error OFF Seq. Seq.
Driver ready OFF OFF OFF
Driver enabled OFF OFF ON
If the STS LEDs are flashing, the following sequence occurs:
Seq. Meaning STS
1 Error code start FLASH FLASH
2 It indicates the tens in the error code FLASH D OFF
3 It indicates the units in the error code OFF FLASH U
4 Repetition of the sequence from point 1
After the simultaneous flashing of the orange and green LEDs, count the number of flashing of the orange LED and you
will obtain the number of tens in the error code; if you count the flashing of the green LED, you will obtain the number
of units in the error code.
Example: 1 flashing of the orange LED, 4 flashing of the green LED: the error code will be 14.
See chapter 9.1 for the error decoding.
8.4 LEDs I1, I2 and TO
I1, I2 and TO concern the STO safety system. Their meaning is specified in details at paragraph 6.2.3.
8.5 LEDs A and L
The LEDs A and L concern the field bus connections (F1 and F2). The field bus FLxIO has no LED.
For the field bus Ethernet IP/Sercos III, the LEDs have the following meaning:
Meaning A L
Disconnected cable or no network signal X OFF
Network signal present, but data packs absent OFF ON
Network signal present, data packs present FLASH ON
