LINK Systems 5100-8 Tonnage & Analog Signal Monitor - Manual (Page 72)

Doc #: L-802-1110 Page 70 Rev. 02
One opto-isolated input is also provided to allow triggering measurements not associated with the crank
position. For instance, a PLC could trigger a measurement based on some condition external to the
press.
Figure 40 shows how the 5100-8A option mounts to the main circuit board. The board to board
connectors (see the “5100-8A Option Connector” in Figure 39) must be aligned when the boards are
mated. Four 6-32 screws with lock washers secure the option board to the main board.
When installed, the functions of this option are accessed through the ANALOG MONITOR softkey on
the main screen (see Figure 4 on page 13). If dedicated analog monitor modules are already installed,
then the channels supplied by the tonnage monitor will appear as the last page of channels. Instead of
“Module 1”, “Module 2”, etc., these channels will be labeled as “Module TM”. Refer to the Analog
Signal Monitor manual for details on operation.
WARNING! ALWAYS remove the power connector from the module before
removing the module from the card rack! Lethal voltages are present
on the circuit board when the unit is powered!
NEVER apply power to the board when it is out of its enclosure.
