Hypertherm Shape Cutting Control - Manual (Page 18)

AC Input
The AC power cable is inserted into the AC power connector and plugged into a
standard 3-way 110 or 220 volt outlet. The control has a universal AC input
power module that allows the user to plug into either voltage without changing
additional jumpers. In addition, the AC Power connector contains an integral
fuse receptacle and line filter.
A remote communications link can be connected to one of the two serial ports
and an external ground (PE) lug for earth grounding of the unit is also provided.
Serial Port
Please refer to the Ports Information section of the Installation Guide for
additional information on configuration of Serial ports for communication. Note:
Serial ports for the MicroEDGE are not optically isolated. Appropriate grounding
or after market port isolator or protocol converter to add optical isolation is
recommended.
I/O Configuration
The cables that connect the control to the cutting machine are attached to the I/O
(Input/Output), and the DRIVE/ENCODER connectors. For the purposes of this
guide Single Ended I/O is referred to as Type “P” configuration.
The information provided here is the basic information for connection of the
shape cutting control to the cutting table. Each machine interface will vary
slightly based on the cutting table configuration and features. Additionally, I/O
pinout information may vary slightly based on the configuration of the selected
I/O and their locations. Changes to the I/O configuration may be made in the
password protected I/O screen. All controls are shipped with the default
selection of Inputs and interface locations for the selected control Interface (I/O)
configuration. Installation and service should only be performed by a qualified
service technician.
I/O Connector
The I/O connector is a standard sex circular CPC connector from AMP. This
connector was specifically chosen for its rugged industrial design and its metal
insulation characteristics for EMI/RFI noise immunity.
In the single ended I/O scheme, a ground is provided on the I/O pin. The
advantage to single ended I/O is that it takes one pin for each point versus two
for the double-ended I/O scheme, thus increasing the total number of I/O points
available to the user.
