LED Indicators
Switch
PWR LED
AS-Interface voltage; green LED
■
Green: OK status
■
Flashing green: address 0 or peripheral fault
FAULT LED
Fault indication; red LED
■
Red: communication error or address is 0
■
Red flashing: peripheral fault
AUX LED
External auxiliary voltage U
AUX
; green/red dual LED
■
Green: voltage OK
■
Red: voltage reversed
LED INT
(VBA-4A-KE5-IJL/UJL
only)
Internal output voltage active; green LED
■
Green: internal output voltage from AS-Interface
■
Off: output voltage from auxiliary voltage
LED OUT1 ... OUT4
(OUT3, OUT4 only for
VBA-4A-KE5-IJL/UJL)
Status of output signal; yellow LED
■
Yellow: output value within value range
Continuously illuminated: output in current mode
Continuously illuminated, briefly interrupted: output in voltage
mode
■
Flashing yellow: wire break (at current output) or output value
outside of value range
Note!
Behavior of the LEDs
LEDs OUT1 ... OUT4 are continuously lit up if the corresponding output is configured as a
current output. For outputs in voltage mode, the corresponding OUT LED flashes, going out
briefly and then illuminating for a longer period. See chapter 7.
Note!
Wire Break Detection
At a current output, a wire break is reliably detected if the set current > 10
µ
A.
From 1
µ
A to 10
µ
A, wire break detection cannot be guaranteed.
If power = 0, wire break detection is deactivated.
INT/AUX switch
(VBA-4A-KE5-IJL/UJL
only)
■
Set to INT:
output voltage from AS-Interface (max. 100 mA)
■
Set to AUX:
Output voltage from auxiliary voltage (max. 600 mA)
Warning!
Only use the switch when de-energized
Only adjust the INT/AUX switch if the module is not supplied via the AS-Interface or the AUX
auxiliary voltage!
