LINK Systems OmniLink II Press Automation Control - Manual (Page 113)

August 30, 2002 Manual Version 1.0 6.8
Since there can be up to five Digital Die Protection and Process Monitors connected to each OmniLink
II Press Automation Control system, each of the Digital Die Protection and Process Monitor must be
assigned an unique Module Number. The selection is made by use of the rotary switch that is located on
the door mounted top circuit board. These numbers should be assigned sequentially starting at one.
Two units cannot share the same Module Number. When powered, the unit will display its module
number on the front door numeric display.
When the Die Protection screen is selected, the lowest numbered module will be displayed first.
Subsequent number modules are selected by use of the NEXT PAGE softkey. If it is determined that
one particular module will demand more operator attention that other modules, this module should be
assigned number one.
Section 6.4.5 Sensor Connections
The Digital Die Protection and Process Monitor modules allow for input sensors to be connected to the
unit through several different means. The sensors can connect to the internal input terminal block.
Sensors can plug into the optional binding posts or micro connector receptacles on the front door of the
enclosure. Sensors can connect via the optional quick die change receptacle. Sensors can connect to the
optional die mounted sensor dock. These connections are shown in Figures 6.2 for Model 5120 and
Figure 6.3 for Model 5121. It is important to note that some channels can have multiple means of input.
Some channels can have their input connected via a terminal block, binding post, micro connector, or
quick die change receptacle. Normally only one sensor will be connected to a channel. Normally only
one of the input means will be used per channel.
Section 6.4.5.1 Sensor Connection via Internal Terminal Block
All channel inputs are available via the internal terminal block. This terminal block is located on the left
side of the circuit board on the bottom of the enclosure. Also available on this terminal block are the
connections for the unit’s 24 volt DC power supply. This supply can be used to power sensors.
Units that have the quick die change receptacle will already have one wire connected to each input
terminal. Normally the quick die change wire is not removed when a sensor is wired to an internal
terminal connection.
Section 6.4.5.2 Sensor Connection via Optional Binding Posts and Mico DC Connector Receptacle
If a unit is equipped with the optional binding posts and Micro-DC connector receptacles, sensors can be
connected to channel inputs 1 through 4 via the binding posts and to channel inputs 1-8 via the Micro-
DC connector receptacles. The binding posts are intended for sensors that have a single connecting
wire. These are sensors that conduct to machine ground through the material or the tooling. The wiring
for the Micro-DC connector receptacles is shown on Figure 6.2 for Model 5120 and Figure 6.3 for
Model 5121. Connection of sensors to the Micro-DC connector receptacles can be made either with
molded Micro-DC extension cables or by attaching field-wireable Micro-DC connectors to un-
terminated sensor cables.
A low input impedance option is available for sensors wired to the binding posts or to Micro-DC
connector receptacles 1-4. If the Micro-DC connector receptacle is used, the sensor must be wired to
pin 2 of the Micro-DC connector. This low input impedance may be required for grounding type
