1. Product introduction
The SCB-PT series passive pneumatic controller is a special pneumatic
drive controller of the SRT flexible end fixture, which can output the
adjustable pressure of 70~100 kPa. Under the trigger of the external
equipment, the flexible end fixture is driven to perform the opening and
grasping action. The positive pressure output corresponds to the
clamping action of the fixture, and the negative pressure output
corresponds to the opening action of the fixture. The controller can be
conveniently equipped with flexible end fixture and other automation
equipment to form a flexible grasping system.
Functional characteristics：
1、Real time status display：
The SCB-PT series controller is equipped with air pressure display and
indicator lamp. The air pressure display can display the real time air
pressure value and set air pressure of the air pressure output port, and
the indicator lamp can display the current working state of the controller.
2、Accurate high speed response
SCB-PT series controllers optimize the control system of the previous
generation of controllers, which can adjust the output pressure more
accurately and quickly, and achieve the set output pressure value in a
short time to meet the requirements of certain working environments.
3、Three pressure regulating modes
SCB-PT series controllers are equipped with adjustment knobs, which
can manually adjust the set pressure of each gear grab and opening,
which is convenient, simple and saves time.
The SCB-PT series controller has eight stalls, which can store up to eight
groups of grasping and opening pressure values, and switch through I /
O signals to deal with complex working conditions.

SCB-PT series controllers support communication voltage regulation.
After the controller connects the communication equipment through the
data line, the set pressure value can be adjusted in real time.
4、Fault alarm function
The SCB-PT controller will detect the output pressure in real time. When
there is air leakage in the end fixture, the indicator light will become red,
and the control system will output signals to facilitate the operator or the
external control system to make judgments and improve the reliability of
the production line.

greater than 50W.
2) Gear selection port
There are eight editable stalls in the PT series controller, and eight sets of
different positive and negative pressure settings can be edited by
manual adjustment or PC software. Usage method : The IN-COM port
of the controller is connected to the output COM of the robot or PLC.
When the logical signals of SW1, SW2 and SW3 ports are 0, the first gear
is triggered. The pressure value of the clamping and opening of the end
fixture driven by the controller will be changed to the set value of the
first gear. When the logical signal of SW1 port is 1, and the logical
signals of SW2 and SW3 ports are 0, the gear 2 is triggered, and the
pressure value of grasping and opening the end fixture driven by the
controller will be changed to the set value of gear 2. File three to eight.
The trigger voltage range is DC24V ± 10 % and the current is more than
100mA. According to the working condition, the appropriate gear
position corresponding to the positive and negative pressure output
value can be selected. Compared with the table below, the I / O signal
triggering the gear position can be input, and the positive and negative
pressure trigger port can be combined to drive the end fixture to
complete the grab or open.

3) Grab, open and reset trigger ports：
The robot or PLC can output positive pressure, negative pressure,
maintenance and zero pressure by using I / O signal to control the outlet
interface of the controller through this port.
Usage : Connect the IN-COM port of the controller to the COM of the
output terminal of the control model of the robot or PLC. When the logic
signal of the IN-P port is 1, the controller performs the positive pressure
output and the end fixture is the grab state. When the IN-N logic
model is 1, the controller performs negative pressure output, and the
end fixture is open. When IN-P and IN-N are both 1, the controller
performs pressure relief action and the flexible gripper is in natural state.
When the reset port logic signal is 1, the controller is reset state, clear
alarm information, etc., and restore to the initial state.

3. Installation
3.1 Installation fixed
The installation hole of SCB-PB series controller is located at the bottom
of the controller, and the size is as follows. Please use M3×4 bolts when
installing.
Installation Precautions ：
1、 When the equipment is installed, ensure the equipment is installed
firmly.。
2、When fixing equipment, don 't squeeze equipment into or out of the
air tube or wire。
3、Please do not suspend the controller to a high position to avoid the
controller damage caused by falling.。
4、 Installation of controller grounding in special environment, such as
strong magnetic interference environment。
3.2 Pneumatic connection

Ensure φ 10mm inlet length is sufficient to reach the controller inlet
interface. The φ 6 mm outlet pipe should be connected to the end
fixture after the filter, and the total length is in the range of 3-5 m.
When the gas path is connected, it is ensured that the trachea is
completely inserted into the fast insertion joint. In the insertion process,
there is a clear sense of sudden frustration to prove that the gas path is
connected correctly. After opening the industrial gas source, twisting the
debugging switch, and running three to five times, it is ensured that the
gas path is connected well. If air leakage is found, the gas source and
power supply switch are shut down immediately, and after the air
leakage is eliminated, it can be continued to use.
Notes on Airway Connection：
1、Fully blow or wash the end, oil and dust of the pipe before piping.
2 、 When the controller is connected to the trachea, the bending and
blockage of the trachea are avoided as far as possible, otherwise it is
easy to cause the instability of the pneumatic system of the controller.
3、Do not make mistakes in product inlet and outlet.
4 、 Ensure the air tightness of the product outlet to the end actuator
trachea.
5、Series filter can ensure the service life of the end fixture and pneumatic
controller, and the filter should be between the controller and the end
fixture.
