DNSL-ZMB, DNSL-ZMT: Standstill and motion monitoring
The Central module DNSL-ZMB may be used to monitor two motions for safe standstill and safe speed. For speed
sensing at a motion two proximity switches could be used. This Function is also with DNSL-ZMR available.

To use motion monitoring the function DS1 and/or DS2 in the SafeLine DESIGNER must be selected.
I11, I12 and I13 are not available for safety circuits in this case.
Selection of the individual speeds is accomplished by entering the corresponding frequency in Hz into the parame-
ter fields.
The maximum Input-frequency for I11 – I14 is 1200Hz.
Proximity switches requirements :
2 signals with 180° phase offset. One switch at the cog the an other at the gap. Positive switched to 24V DC (PNP)
DNSL-ZMB, DNSL-ZMT: Output usage
Output O1 function may be defined in the parameter layer to one of the following:
SLOK : Output indicating system ready
T8 : Semi conductor switch
FrqIn : Frequency input (maximal 1200Hz) single channel motion control.
The output O1 can be redefined as frequency input in the parameter layer to function
as a one-channel not safe motion control. As impulse device a proximity switch may
be used.
Setting the value for the motion control will be done using the PROFIBUS.
The proceeding of programming is received by DINA Elektronik.

To reset the contact DZ2 the maximum of the speed has to be decreased more than
10% a the virtual input RTDS has to be switched to virtual 24V.
Programming Layer
O2 and O3 are redundant outputs made of two positive switching semiconductors. These outputs may be activated
directly by external inputs or by virtual connections from NC, NO, logic elements, time relays etc.
R13/R14, R23/R24 are 2 relay outputs and they are configurable to the following:
a) two independent NO contacts, safety category 2, activated by K1, K2
b) two redundant NO contacts, safety category 4, activated by S1 and Q.
Q may be connected to or connected via an external input. S1 and Q are displayed in the programming layer
only in this mode.
Version a and b will be factory-made. The factory-made configuration has to be selected via the parameter mask.
Note: All outputs will be monitored constantly for wrong behavior independent of the function. If an error is de-
tected on one of the outputs, all outputs will be switched off.
Special function:
RTDS: Virtual input to reset the interlock of the virtual contacts of the motion control at the central mod-
ule and DNSL-DS, DR after the actual values are below the limit values. This virtual input can be also used to reset
safety shutdown mat. The virtual input RTDS must be held at virtual 24V for more then 500ms. For this function a
hardware input I1-I6, I11, I12 rather a hardware input at a function module or virtual output can be used.
Pulse generator via IF1:
With the selection „ON” via the parameter mask the function of a pulse generator (Takt Generator) is possible via
the virtual contact IF1. The right connection can be used to control an hardware output, the left to virtual
The time of the signal „High“ and the signal „Low“ can be defined. The stepping is 100ms. 1 = 100ms, 10 = 1s etc.
