Ohmic workpiece search
sensor PLL-R2

01. General information
The PLL-R2 set is designed for metal workpiece surface search in C C plasma cutting
devices.
The set consists of two devices: power supply unit PLL-R2P and measuring unit PLL-R2S.
The measuring unit is to be installed next to the torch on the Z axis, and the PLLR2P power
supply unit is to be installed onto the control panel of the C C system. The units are
connected via cable (Fig. 7).
The sensor allows to adjust the sensitivity. PLL-R2 is equipped with trigger indicators, as
well as an opto-isolated interface for connecting to a C C machine controller.
The sensor provides with measurements when cutting parts are located under water (the
response threshold is selected individually by the sensor response sensitivity adjusting).
The measuring unit PLL-R2S has the international protection class IP50 (protection
against dust penetration in quantities, that do not affect the performance of the product).

05. Description of sensor operation
An ohmic sensor allows to detect the workpiece surface when the torch moves down.
When the torch cap touches the workpiece, the “Sensor 1” signal appears. If for any reason
the first sensor does not work and the Z axis continues moving down, then dZ mm (Fig. 9)
will trigger sensor 2 and two signals will immediately appear at the output: “Sensor 1” and
“Sensor 2”. In this case, to obtain the torch height above the workpiece surface, it is
necessary to correct the Z coordinates by the distance dZ.
The sensitivity control is designed to reduce the sensor sensitivity in the case of strong
interference, which can cause false activation, or to increase the sensitivity in the case of
contaminated workpiece.
06. Warranty
Warranty service life is 12 months from the purchase date.
The warranty is only preserved if operation and scheduled maintenance conditions are
observed.
