from 115VAC or higher voltage conductor.
5.4.5 Connecting an Optional Remote Reset
A remote reset pushbutton can be wired into the System 1100
allowing alarms and errors to be reset from a remote location. To
install the remote reset button, connect one side of a normally
open pushbutton to the RST terminal on the System 1100 Logic board.
Connect the other side of the pushbutton to the GND terminal
adjacent to the RST terminal.
Note that the remote reset button is pressed, the System 1100 drops
out the stop circuit relay during the reset sequence. Care should
be taken in placement of the remote reset pushbutton to avoid
nuisance stops due to unintentional pressing during production.
5.4.6 Input Power and Machine Control Connections
The terminals for connecting 115VAC
power to the System 1100 and connecting
the System 1100 output relay contacts
into the machine control system are
located on the power supply module on
the left side of the interior of the
System 1100 enclosure (Logic Unit
enclosure for panel-mount units).
The 115VAC power supply wires and
output wires should be connected as
shown in Figure 24, and run in a
separate conduit from the low voltage
d.c. wires connected to the Logic board
and Channel cards.
Connect the normally open contact (held
closed during normal operation) on the
power supply terminal strip into the
m a c h i n e t o p s t o p c i r c u i t .
Alternatively, The System 1100 can be
connected to machine emergency stop.
Connecting the System 1100 output relay contact in the emergency
stop circuit may or may not enhance die and machine overload
protection by reducing the machine clutch torque before an overload
reaches its maximum value. The pneumatic reaction time of the
