Setting Cross fault detection
Switch S1 is for selecting with or without cross fault detection at the e-stop
button resp. on safety gate.
For connection please see application examples.
!
ATTENTION! The setting of S1 has to be made before
starting the device.
Setting Start-Mode
S2 is used to change between automatic and manual restart. On automatic
start also the terminals S33 - S34 have to be linked.
With the function manual start a start button has to be connected to
terminals S33-S34. The unit starts up with the negative edge of the start
button signal.
For connection please see application examples.
!
ATTENTION! The setting of S2 has to be made before
starting the device.
Line fault detection on On-button
A line fault detection is only active when S12 and S22 are switched simulta-
neously. If The On-button is closed before S12, S22 is connected to voltage
(also when line fault across On-Button), the output contacts will not close. A
line fault across the On-button which occurred after activation of the relay, will
be detected with the next activation and the output contacts will not close.
!
ATTENTION! If a line fault is removed while the unit is
powered up, the unit switches on.
