Component Identification and Explanation

Pin and board numbers correspond to each other. 11 and 12 are not used. 8 is blank.

This is the Divided Arc Voltage Jumper Location.

Closed: 16 to 1 Arc Voltage (1-10V) (If 16 to 1 is needed, remove cover and move jumper to center and remaining pin.)

Open: 50 to 1 Arc Voltage (1-3V) (Unit is shipped with jumper installed in open position. Do not discard jumper or remove.)

RAW ARC VOLTAGE

•

Pins 1 and 2 activate (turn on) the plasma cutter to start cutting.

•

Pins 9 and 10 give the "OK-To-Move" signal. These are Dry "N.O." style contacts. It is a non-electronic switch that closes when the pilot arc transfers to the cutting

arc. Sometimes referred to as "Arc OK".

•

Pins 5 and 7 provide the raw, undivided arc voltage, which is used by some controllers to adjust the height of the torch (THC). This is the actual cutting voltage. It

runs through 2 -100KΩ resistors to prevent arcing at the connector plug. Many, but not all controllers have a raw voltage option, and is dependent upon the imped-

ance of the input. The raw arc voltage can be used when other systems look for or expect higher voltage signal from 50 to 1 arc dividers for certain brands that pro-

duce a higher arc stretch voltage.

•

Pins 4 and 6 provide the divided arc voltage. This is selectable by moving the jumper on the CNC circuit board inside the unit to create either 16 to 1 (1-10V) or 50

to 1 (1-3V) ratio to the raw arc voltage output. Divided voltage is used by many controllers for regulating torch height control (THC). The jumper is configured for

50 to 1 voltage output (1-3V) which is technically "open", but the jumper is installed in a neutral position. The machine must be opened and the jumper repositioned

for 16 to 1 arc voltage (Remove rear cover and metal cover only to access!) The jumper for 16 to 1 arc voltage will bridge between the center pin and the other open

pin position. If using 50 to 1, no change is needed. Retain the jumper for testing the unit.

•

Pin 3 is what some controller manufactures refer to as "Ground" this is connected directly to the work piece lead, which is actually a positive polarity. If the controller

has a pin for ground this is likely the pin to use.

Please be aware that Everlast does not offer technical support for individual manufacturers. The CNC manufacturers should provide all necessary details for proper con-

nection and setup of their machines. Cable colors and wire configurations are the CNC manufacturers responsibility. Everlast supplies the necessary pin-out information

to the rear of the machine along with a plug adapter (CNC models). After this, all the connections are the responsibility of the CNC table owner and the CNC manufacturer.

The Plasma cutter currently comes configured for 50 to 1 voltage divider for the THC. This is a 1 to 3V operating range. Some CNC tables are configured for 50 to 1

voltage divider but are calibrated based on particular brand with a higher arc voltage range than Everlast and many other brands supply on the standard volt/amp curve.

In this case, the voltage range may be 1-5 volts and will not work. In this case, the voltage divider on the CNC needs to be recalibrated, or you will need to use the raw

arc voltage if the CNC plasma table control system is equipped to read raw arc voltage. Do not modify the plasma cutter control board in any way or the warranty may

be voided. Modification of the CNC control board inside the machine may damage the machine and cause early failure.

Do not connect anything directly to the output terminals or leads. Do not connect anything from the controller to the chassis of the cutter, especially a ground lead. Do

not install any kind of converter or divider inside the machine. Do not modify the CNC control board, or the warranty will be voided.

Raw Arc Voltage is dangerous! Use caution if using the Raw Arc Voltage. This is the most accurate method of control, but careless handling may result in shock or

injury to the user. Many systems use either a 50 to 1 (1 to 3V) or a 16 to 1 (1 to 10V) signal to control the torch height with a raw arc voltage option.
