Page 24: Monitoring Function
2.2.2 Monitoring function Monitoring the state of sensor BLPS monitors the state of the detecting beams and outputs safety control signals according to the operating mode and the detecting results Such as: in the protection trip, if the effective detecting beam is shaded, the OSSD outputs are on the OFF-state. -
Page 25: Operating Mode
NOTE: This function is only offered by SP controller. 2.3 Operating mode 2.3.1 Sensor used alone The operating mode can be set by the assist of control system of the bender when sensor is used separately. 2.3.2 Sensor and SR controller used together SR controller provides three operating modes: normal mode, folding box mode and muting mode, using the mode switch (self-resetting) to change the operating mode. -
Page 26: Sensor And Sp Controller Used Together
Fig.2.5 Operational timing chart of folding box mode of SR Muting mode Under muting mode, all the protection areas (L1, L2, L3) are ineffective and SR controller can not provide protection. Fast down control output (13/14, 23/24) still keeps on ON-state even if there is an object in the detection area. - Page 27 being valid and the gearshift signal is invalid), slow down stroke and back stroke are not protected. Normal mode Under normal mode, all the protection areas (L1, L2, L3) are effective. Any beam is blocked in the protective stroke, fast down control output (13/14, 23/24) is cut off to prevent stroke start or stop it to avoid serious injury.
- Page 28 When the central protection area of sensor keeps on light-shaded state, trigger the down going signal again, the fast down control output and the slow down control output turn on at the same time and the bender will finish the working stroke at the set slow down speed. The folding box mode should be selected when the workpiece only blocks L1 protection areas before the bender change the speed of the working stroke, such as box-shaped parts.
