DNSL-ZMT: usage of inputs I16 to I20 for safety shutdown mats
For working with safety shutdown mats (max. 5) virtual re-
dundant contacts TM1 to TM5 are provided. If the safety
shutdown mats is
OK
and not activated the corresponding
contacts TM1 to TM5 are closed. Stepping on the safety
shutdown mat or an internal malfunction of the mat will open
the corresponding contact. Contact closes again if no one is
on the mat.
A manual reset must be programmed using the logic module
in the DESIGNER.
The status of TM1 to TM5 may be monitored using the
Profibus.
The values for the analogue edges will be set using:
AN01 to AN05 for lower level
AN06 to AN10 for upper level
AN01/ AN06, AN02/ AN07, AN03/ AN08, AN04/ AN09 and
AN05/ AN10 are paired values.
Note for initial start-up
:
At the clamp the measured voltage against 0V is 8,5V with a
free mat.
Additional parameters are not necessary.
Unused clamps I16-I20 may be left unconnected.
Note: Digital inputs and analogue safety mat inputs
will be
processed in two channel mode and tested for plausibility on
the Central – and all Function modules. There is no single
channel processing.

are for a safety mat with
shorting outputs using an
external 8,2Kohm Refer-
ence resistor.

DNSL-ZMT: usage of inputs I16 to I20 for current source monitoring (4 to 20mA)
This inputs can be used to monitor the current value with an internal resistance of 500Ohm. The switching thresh-
olds can be defined as for shutdown mats. Lower value and upper value must be entered. The interpretation will be
done via the virtual contacts SM1 to SM5. It may be to control outputs with right connection of the contacts. The left
connection can be linked with v24V or with another software elements.
0V potential of the current source has to be connected with A2 of the central module.
