Settings of the DIP switches, DM-F Local
Note
The set DIP-switch position in the Device Integration Manager user interface (which can be
done using the mouse pointer) is transferred to the basic unit as part of the standard
download. However, it does not affect the function of the DM-F Local.
This way, the desired function is already set during parameterization.
The effective parameterization must be set using the DIP switches on the front of the DM-F
Local (see table below and/or "Failsafe Digital Modules SIMOCODE pro Safety Solutions"
manual).
The basic unit compares the set position (from the download) with the actual position at the
DM-F Local. If these differ "Configuration deviation" is output!
DM-F Local
Without / with cross-circuit detection

Description
Without / with cross-circuit detection Cross-circuit
detection is only possible with potential-free sensors.
In this case, the sensors must be connected between
T1 - Y12, Y33 and T2 - Y22. The device anticipates
the T1 terminal test signal on terminals Y12 and Y33.
Likewise, the T2 terminal test signal is anticipated on
terminals Y22 and Y34. In the event of the signals on
Y12, Y33 and Y22, Y34 not corresponding to the T1
and T2 test signals, the device detects a sensor fault.
When electronic sensors such as light arrays or laser
scanners are connected, cross-circuit detection must
be disabled. The DM-F Local no longer monitors the
sensor inputs for cross circuiting. Usually, the outputs
of safety sensors (OSSD) are monitored for cross
circuiting in the sensor itself. When the device has
been parameterized as "without cross-circuit
detection", the T1 and T2 test outputs are switched off
and must not be reconnected. The DM-F Local
anticipates a +24 V DC signal from the same current
source from which the device is powered on inputs
Y12, Y22, Y33 and Y34 (DM-F Local-*1AB00 only) or
from T3 (static +24 V DC).With the DM-F Local-
*1AU00 device version, terminal T3 must be
connected to the potential-free sensor contacts, due
to the galvanic isolation of the input circuit and the
sensor supply.
