Self - diagnosis function: can be self - diagnosis, check for errors. In addition, self-diagnostics are performed periodically during the run (during response time).

External EQUIPMENT MONITORING function: CHECK for misoperations, such as welding of external relays (or contactors) that control dangerous parts of the machine. This function continuously monitors the external device of the optical receiving device to monitor whether the specified voltage is applied to the input line. When an error occurs, the system enters the interlocking state. The maximum time for which the relay action delay is not recognized as an error is 300ms.

Interlock function: When open or the optical axis is blocked, the safety output will be turned off at this time and will remain in this state until the reset input is applied.

There are two types of reset interlocking, namely the "automatic reset method", which automatically opens the control output after the barrier is removed, and the "manual reset method", which keeps the control output closed until the reset signal is applied after the barrier is removed.

Automatic reset: After the occluded object is removed from the detection area, the safe output will be automatically turned on. When workers cannot enter the area between the test area and the dangerous parts of the machine, automatic reset method is used.

Manual reset: When there is no object causing occlusion in the detected area, apply the reset input to turn on the safe output. This function prevents unnecessary startup by manually resetting the machine through the reset switch after confirming safety.

Masking function: The raster security function can be temporarily disabled so that the security output remains on even if the optical axis is occluded.

Local shielding function: When the workpiece passes through the optical axis, the local shielding function can ensure the safety without activating the shielding.

Position DETECTION SHIELD: When the robot is in a safe position, use a limit switch or other measure and then enable the shield function.

Fixed blanking area function: can disable the specific optical axis in the grating. This function keeps the safe output on even if some parts of the mechanical device are located in the detection area.

Floating blanking AREA function: can increase the detection radius of the grating, thus improving its detection ability, when multiple objects are detected, turn off the safety output. If there is a moving object of fixed width in the detection area, but it is not necessary to detect the object, you can disable the detection function.

Alarm area function: the detection is divided into detection area and alarm area. When the object enters the warning area, the warning light will be lit or the buzzer will sound the alarm without stopping the mechanical equipment.

Series function: series so that multiple sets of safety light curtain can be used as a set of safety light curtain. When in use, the controller only needs to be connected to a set of light curtains to prevent mutual interference.
