Notes

To select automatic restart terminals S13 - S14 must be bridged, S33 -
S34 must be opened. Open terminals S13 - S14 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
and K2 have released and then S12 (channel A) and S32 (channel B)
t
are switched simultaneously. If the On-button is closed before S12, S31,
S32 is connected 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, S31, 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 gold plated contacts of the BH 5928 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.
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.
Y39 - Y40 must be closed to have timed outputs. By opening the bridge
between Y39 and Y40 the time delay can be interrupted immediately. Wit-
hout bridge the contacts switch without delay.
The time setting has to be sealed by the user after test.
