7.2.6. Digital outputs (relay contact)
These relay contacts can be used, e.g., for a Versatile Limit Switch
(VLS).
For further information on VLS see chapter 7.2.7, below
As standard the definition of the digital outputs is as follows:
Name Meaning
X105
Pin no.
DIGOUT_1 OK/ALARM Pin 10, 11
DIGOUT_2 RUN Pin 12, 13
DIGOUT_3 WARN Pin 21, 22, 23

Closed ≙ OK
OK = Device ready for operation
Closed ≙ Run
RUN = “VOLTAGE_ON”
Change-over contact
WARN ≙ Warning
Table 46 Standard function of the X105 relay outputs.
Maximum switching current 1 A; maximum switching voltage: 125 V
The rest of the pin definition for X105 is listed in Table 147, page 271.
7.2.7. Versatile Limit Switch (VLS)
7.2.7.1. Description of VLS function
Using the VLS function the following analogue outputs on the X105
interface can be monitored:
Voltage
Current
Power
If programmed limit values are not respected, an output relay is
switched.
You can select the type of relay that is operated via the interface X105:
“Warn” relay (normally open)
“Run” relay (normally open)
“OK/Alarm” relay (normally closed/normally open)
For further information see chapter 7.2.6, oben.
The following VLS functions can be selected:
Exceeding a threshold
Dropping below a threshold
Entering a window
Defined value range is reached
Leaving window Defined value range is left
