Quit for safety circuits (SC)
Central modules manual
•
Quit via quit-terminal, RTDS symbol or FBI7 at fieldbus
•
Quit signal change
, independent from source
•
Quit-time Qt is selectable 0, 1, 3 and 5S
•
FBI7 is active, FBI7 as follow to use:
SK1: FBI7.1, SK2: FBI7.2, SK3: FBI7.3, SK4: FBI7.4, SK5:
FBI7.5
•
Central module automatic
•
Quit signal is constant on, not necessary if “Off”
selected.
•
Terminal is free for another using
Function modules
•
Quit is only possible via the quit-terminals.
•
Signal change is needed . Qt is fixed at 1s.
•
Automatic: quit signal constantly on
•
No quit-signal: select automatic, quit-terminal at
24V.
•
Protection cover: connect quit-signal to quit-
terminal and select automatic.
•
E1 and E2 controllable static or dynamic
•
For dynamic arrange clock outputs at SL.
:
•
The function is only important if SC1 via I1-I3 or SC2 via I4-I6 at the central module is used as an
emergency stop.
•
With an external or internal error an emergency stop will be generated by SAFELINE.
•
During the SLOK time SAFELINE works normally.
•
After all outputs will be turned off. The plant stops.
•
The SLOK Delay time has to be selected such as long, that the plant will be stopped safety.

Standstill and speed monitoring
12.1
Standstill and speed monitoring at DNSL-ZMB/ ZMR/ ZMT
•
2 safe monitoring for standstill and motion in different function modes for 2 axles
•
Two sensors for every monitoring are required
•
During standstill one sensor is active (24V signal).
•
Sensors are constantly monitored

Requirement at Proximity sensors
•
Two sensors for every monitoring
•
At the cogwheel one sensor opposite to cog other to gap
•
During standstill at least one sensor has 24V signal.
