Self diagnosis function: It can perform self diagnosis and check for errors. In addition, self diagnosis will be conducted regularly during operation (during response time).
External device monitoring function: Check for misoperation, such as whether the external relay (or contactor) controlling the dangerous part of the machine is welded. This function continuously monitors the external devices of the light receiving device to see if the specified voltage is applied to the input line. When an error occurs, the system enters an interlocking state. The maximum time for relay action delay not to be recognized as an error is 300ms.
Interlocking function: When the switch is turned on or the optical axis is blocked, the safety output will be turned off and maintained in this state until a reset input is applied.
There are two types of reset interlocking, namely "automatic reset method" and "manual reset method". The former automatically opens the control output after removing the obstruction, while the latter keeps the control output closed before applying a reset signal after removing the obstruction.
Automatic reset: After the blocked object is removed from the detection area, the safety output will automatically turn on. When workers are unable to enter the area between the detection area and the hazardous parts of the machine, an automatic reset method is used.
Manual reset: When there are no objects obstructing the detection area, the reset input is applied to turn on the safety output. This function can manually reset the machine through the reset switch after confirming safety, thereby preventing unnecessary startup.
Shielding function: The safety function of the grating can be temporarily disabled, so that even if the optical axis is blocked, the safety output can remain on.
Local shielding function: When the workpiece passes through the optical axis, the local shielding function can ensure safety without activating the shielding.
Position detection shielding: When the robot is in a safe position, use limit switches or other measures, and then enable the shielding function.
Fixed hidden area function: can disable specific optical axes in the grating. Even if certain components of the mechanical equipment are located in the detection area, this function can still maintain the safe output on.
Floating hidden area function: can increase the detection radius of the grating, thereby improving its detection ability, and turn off safe output when multiple objects are detected. If there is a fixed width moving object in the detection area, but it is not necessary to detect the object, the detection function can be disabled.
