• THC wiring with corner low-speed( Corner signal/Torch height control signal)
When the THC takes corner low-speed input control signal, the HYD-2100 «corner low speed» output signal is used to control the THC’s corner low-
speed input (Auto mode enable/disable signal). The CNC signal is an open-colletor transistor output, with the default low-level effective. When the THC
is not matched type, it needs to be converted by the relay.
THC wiring with automatic / manual
When THC is automatic / manual control function instead of corner low-speed input, the system needs to use the «corner low-speed» output to control
the THC’s automatic / manual signal. When the THC is not matched type, it needs to be converted by the Relay. Meanwhile, it needs to change the type of
corner low speed from normally-open to normally-closed in the output configuration interface, i.e from red « » to green « ».
• Using THC for initial sense (IHS)
When using the locating function of the THC, the locating of CNC should be closed. The approach is to change the input type of successful locating from
normally-open to normally-closed in the input configuration interface(Section 10.1.3), i.e from « » to « ». There are two types of locating:
The first: locating controlled by the plasma arc starting. CNC output the plasma arc starting, the THC starts arc after IHS, and sends ARC OK signal back
to CNC after pierce. Such THC is available on the market like HYD’s XPTHC series. Such devices can connect the «plasma arc starting» output of CNC
system to the « arc on with IHS» input of the THC, and at the same time in the plasma parameters set the arc detecting time to the value that allows for
completing the testing and starting arc.
Using CNC system locating
When using the Initial Sense function of CNC system, first entering the input configuration interface, set the input type of successful location from
normally closed to normally open type, ie, from « » to « ». At the same time, return the signal of successful location to the input of the successful
location of the CNC.
Output configuration
The number and type of the output could be configured, for example, the igniting output number could be 3, also it could be configured to 07, the output
type could be normally open or normally closed. The detailed methods are shown in figure 61.
Press F5 (Diagnosis) in the main interface, F8 (Systemdef), F3 (Define), enter the password «1396» and press ENTER, F2 (output).
