Chapter 2 - Description of Controls
The IMPAX monitor is comprised of several components which are interconnected by wiring.
All components are mounted on the forming machine except for the IMPAX Control Console
which is isolated on its own pedestal.
The Control Console is the core of the system, housing the microcomputer and power supply.
Its front panel contains the Message Display Panel and the Keypad, through which you can
receive information and enter commands. It also contains the Locking Keyswitch which
accepts the Supervisor’s Key. This key allows the supervisor or operator to ‘program’ IMPAX.
The Satellite Box is the
junction for all the
controls and
components on the
machine. The Reset
Button is the only
operator control. The
red, yellow, and green
Status Lights indicate
the mode of operation
that the IMPAX unit is
in. The Bypass Key
Switch, operated by the
Supervisor’s Key,
disables the relay which
stops the machine and
its accessories, but has
no other effect on
operation. Note: There
is no machine
protection when the
IMPAX monitor is in Bypass mode.
Up to two Machine Position Sensors are used to sense the machine cycle and synchronize the
stop signal. Piezoelectric Sensors are installed in stressed locations near the forming stations;
on the back of the die-bolster or backing plate, on knockout rockers, in punch wedges, etc. A
recess is cut (about the size of a quarter), or a hole is drilled, and the sensor is installed using a
special epoxy adhesive. When the machine is reassembled, the sensors are out of sight, but
sensitive to the forming process.
Relays within the Satellite Box are also wired to the Machine Stop Circuit (if available), as
well as to the feed stop and other accessories, as required to stop the machine and the process.
The Control Console interfaces with the Satellite Box via a multi-conductor cable.
