Unit programming

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 contacts
will not close. If a line fault occurs after the voltage has been connected
to S12, S22, the unit will be activated because this line fault is similar to
the normal On-function. The gold plated contacts of the BG 5925 mean
that this module is also suitable for switching small loads of 1 mVA - 7 VA,
1 mW - 7 W in the range 0.1 - 60 V, 1 - 300 mA. The contacts also permit
the maximum switching current. However since the gold plating will be
burnt off at this current level, the device is no longer suitable for switching
small loads after this (not for variant BG 5925.22/102).
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 moni-
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. 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 see application examples.
