Notes

To select automatic restart terminals S13 - S34 must be bridged, S33 -
S34 must be opened. Open terminals S13 - S34 select manual restart, the
On-button must then be connected to S33 - S34.
Line fault detection on On-button:
The line fault detection is only active when the time delayed relais K1
K2 have released and then S12 (channel A) and S32 (channel B) are swit-
t
ched simultaneously. If the On-button is closed before S12, S32 is connec-
ted to voltage (also when line fault across On-button), the output contacts
will not close. The unit will not restart before the time delay is finished.
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. If a line fault occurs after the voltage has been connected to
S12, S32, the unit will be activated because this line fault is similar to the
normal On-function.
The unit can be operated with single channel and 2-channel operation
with cross fault monitoring. For connection please refer to application ex-
amples.
The terminal S21 permits the operation of the device in IT-systems with
insulation monitoring, serves as a reference point for testing the control
voltage and is used to connect the E-stop loop when cross fault monitoring
is selected.
Connecting the terminal S21 to the protective ground bridges the internal
short-circuit protection of Line A2(-). The short-circuit protection of line
A1(+) remains active.
