3.1、 To POWER
XPTHC-4 uses DC24V or AC24V. The power supply depends
on the motor in Lifter
Transformer ≥ 2 x Motor + 10W
Please using a separate power supply to the XPTHC-4, and
well Ground connected the THC’s metal shell.
XPTHC-4 Voltage supply is as follow：
When DC24V：DC18V~DC36V，the voltage of Motor: 15V~31V. The DC power and the
output power: Vout（Max output）=（Vin (input)-1.4V）*90%.
When AC24V：AC15V~AC27V，50Hz. The output voltage to Motor：15V~31V。
If you want to speed up your lifter, then you could increase the power supply properly.
3.2 、TO Micro Switch( IHS1)
Micro switch IHS is with a special structure in Lifter. There’s a micro
switch in it, usually it’s in “OPEN” status, when the IHS, the torch touch the
cutting material, then it’ll let the micro switch closed, and the THC will let the
torch go up to the IHS height. The IHS1 connect is suitable for external
isolation IHS’s input signal.
Installation of the micro switch see the Fig3-3shows.
Note：the lifter and fixture is not included in the THC (Optional to customers)
3.3、To Proximity switch（IHS2）
When XPTHC-4 is using the proximity switch HIS, should set the P9 parameter,
If there’s mistake on P9 parameter setting, then will have the E5 error alarm.
If the E5 error alarm happens, then could press the “MENU” key button to
recover it;
If the alarm is still existed, then meaning the proximity switch with mistake
connection or operation.
Proximity switch could use NO(normally open) proximity switch,
or NC(normally close) proximity switch.
The proximity switch we offered is NPN and NO proximity switch.
Don’t use the proximity switch, the P9 parameter should be “0”; When use the proximity switch, then
P9 should be “1”.
