FB "COORDINATION" (FB1, DB1)
After processing the FB 217, processing is continued in FB 1:
Network 2
The machine must only start at valid enable from FB 217 (#RE-
LEASE="1") and the start request ("COND1"="1") from the
standard user program. Additionally the tumbler (E_MAGNET)
must be monitored (see "Network 3" below). The "machine"
stops by a failure locking.

"ACT_PAS"
The safety door locks ("COIL"="0"), if
■ the machine is active or
■ a movement of the machine (slowing down movement)
has been detected
Only in case of locked door (COIL="0") E_MAGNET will be "1".
E_MAGNET="1" is necessary for a start of the "machine" (see
"Network 2"). The locking will be active with the start signal.
The start will be active (ACTUATOR="1") one programe cyclus
later as COIL="0".

FC "REINTEGRATION" (FC2)
Network 4 of FB1 calls the FC2, where in case of a passivation
of F-DI or F-DO the reintegration will be implemented. For the
F-DO a memory bit REINT is prepared. With a positive flank of
REINT the F-DO will be reintegrated.
Warning!
In this example, the reintegration of passivated
modules occurs automatically. Use the automatic reintegration
for your application only if it will not
cause any hazards.
A passivation is indicated via LED "SF" lighting up on the module.
The reintegration of an F module may take approx. one
minute.
Operating instructions
No. Instruction Result/Note
1 Plug the actuator into
the safety position
switch.
2 Check the position of
the hinge switch.
Safety door is closed (safety position
switch and hinge switch deliver "1"
signal)
3 Press the START button "Machine" starts (here: indicator light
goes on)
4 Press the and hold the
ACT_PAS button
Simulation of machine movement:
5 Press the STOP button Indicator light goes off, however,
safety door cannot be opened (if still
pressing down ACT_PAS).
6 Release ACT_PAS Simulated machine stoppage. Safety
door can be opened (actuator outside
positioning switch and hinge
switch turned).
7 Repeat no. 1 to 4 –
8 Turn the hinge switch
until the "0"signal.
9 Release hinge switch
and ACT_POS button.
Enable signal is reset and machine
stops.
–
10 Press the START button "Machine" does not start! Safety door
must first be opened completely for
the enable signal to return to "1".
