Operation guide for new user of XPTHC-4

When you install the XPTHC-4, please read this instruction in advance.

1.The power supply is AC24V or DC24V, , please offer the enough power supply , usually for 25W motor , the current couldn’t be less than 3A , the AC24V transformer couldn’t be less than 50W
Power supply=2×motor’s power+10W

2.GND must folow THC instruction , GND resister≤4Ώ

3.UP/DOWN on THC must be same to Z axis lifter

4.To avoid interference, follow cables please use shield cable (connection between CNC controller and THC , to motor , to voltage divider , to IHS card ), especially the cable from THC to voltage divider , please use shield twisted pair cable, and shield net could be grounded .

5.The plasma raw arc volt output CAN NOT be connected to the THC directly , must connect to the voltage divider correctly.

6.The Set arc voltage mode range set to be “0” is better

7.THC “AUTO” signal need same as CNC controller (normally open or normally closed)

8.If use the THC with our small lifter , and use swith IHS method. the Pin3.4 of small lifter should be connected with the IHS1 port of THC (To Micro switch).

9.If use THC with our small lifter,when set the parameters of P6 (limit logic) to be “1” , it must short connect the pin 3.4.5 (To Lifter Port on THC) .
When set the parameters of P6 (limit logic) to be “0” , no need connect the pin3.4.5.

10.Hot key : (1).On work stop status , press “AUTO”and hold on 2 seconds , then press up/down botton to change the set arc voltage value , (2) On work stop status, press “IHS TEST”and hold on 2 seconds , then press up/down botton to change the time of IHS height.
