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
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
insulation monitoring, serves as a reference point for testing the control
voltage and is used to connect the 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.
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 is made with S1.
Switch S2 is used to select automatic or manual restart. Additionally, for
the function "automatic restart", terminals S33 and S34 have to be bridged.
Connect the device according to application examples.
