Notes

Line fault detection on On-button:
The line fault detection is only active when S12 and S22 are switched
simultaneously. If The On-button is closed before S12, S22 is connected
to voltage (also when line fault across On-Button), the output contacts will
33 41 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 con-
tacts will not close.
The terminal S21 permits the operation of the device in IT-systems with
34 42
insulation monitoring, serves as a reference point for testing the control
voltage and is used to connect the E-stop loop when cross fault moni-
M10536
toring 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.
To alter the functions automatic start - manual start and with or without
cross fault monitoring, the switches S1 and S2 are used. These are loca-
ted behind the front cover (see unit programming).
The setting with or without cross fault monitoring on E-stop buttons is
made with S1 (not for LG 5925.54). The LG 5925.54 has always cross
41
fault monitoring.
S2 is used to change between automatic an manual restart. On automatic
start also the terminals S33 - S34 have to be linked. For connection please
42
see application examples.
