Sensor Parts

(3)Maximum switch: this switch sets the top point that bandsaw reaches.

(5)Lower limit switch: this limit switch stop the main motor and starts the bow’s upwards movement.

(6)Blade broken pressure switch: this switch stops the main motor when the blade is broken and provides protection of the operator

and the machine from the damages that a broken blade can cause.

(7)Protection cover switches: this switch stops the machine if any cover is open.

(8)Fotocell: this switch starts the main motor when the blade approaches to the material about 30 mm after the bow begins going down

when start button is pressed. And in manual use, this switch stops the movement before the bow crashes to material when the b ow is

going down.

(9) Leaning switch: It provides to cut the material at adjusted length. If the material is feeded at manual control (by shifting material

feeding buton to 1), material’s tip supppreses switch’s shaft which activates the switch. Switch stops the driver motor to cut the material

at desired length. If the material is feeded at automatic control, material will be feeded automatically by driver motor after bow lifts

up.Material’s tip suppresses the Materıal-End Lımıt switch’s shaft which activates the switch . Switch stops the driver motor and turn on

the solenoid valve to start cutting automatically-which means bow’s going down at the same time.

(10)Materıal-End Lımıt Swıtch ( Sq1 ): When the materıal lenght ıs too shoert to be cut, ıt stops the machıne.
