Booksize power units
300 Manual, (GH2), 06/2008, 6SL3097-2AC00-0BP6
3.8.3.4 X21 terminals: Smart Line Module
Table 3-61 Terminal block X21
Terminal Designation Technical specifications
1 DO: Ready Checkback: Smart Line Module ready
The signal switches to high level when the following
conditions have been met:
• Electronics power supply (X24) OK
• DC link is pre-charged
• Pulses enabled (X21.3/.4)
• No overtemperature
• No overcurrent switch-off
2 DO:
Prewarning
DO: Prewarning
High = no prewarning
Low = prewarning
• Overtemperature warning threshold/I*t
5 kW prewarning: 64 °C, Shutdown: 69 °C
10 kW prewarning: 68 °C, Shutdown: 73 °C
• No regenerative feedback capability due to a line fault
[only monitored when feedback is activated (see
terminal X22.2)]
3 DI: Enable pulses
4 DI: Enable pulses ground
Voltage 24 V DC
Current consumption: 10 mA
Isolated input
Max. connectable cross-section: 1.5 mm
2
Type: Screw terminal 1 (see Spring-loaded terminals/screw terminals)
Note
The Smart Line Module signals ready-to-operate, even though one of the external
conductors is not available. In this case the feedback is deactivated and a warning message
is output to X21/2 (DO, Warning I*t). If the feedback was deactivated by applying a "High"
signal to terminal X22/2 (DI, Disable), no warning message will be output to X21/2 (DO,
Warning I*t).
Note
For operation, 24 V DC must be connected to terminal 3 and ground to terminal 4. When
removed, pulse inhibit is activated, feedback is deactivated and the bypass relay drops out.
If the Line Module is not disconnected from the line supply when the EP terminal is
deactivated (e.g. a main contactor is not installed), the DC link remains charged.
