Parker Products COMPAX-M /-S (L) Light barrier, Interlock # closed # open, Opens interlock, 235

Speed control mode

Programming:

Configuration:

P93 =+4 i.e. speed control operating mode

P94 =+2 i.e. smooth ramp shape

Names of the inputs and outputs:

I7	light barrier	0	# not activated	1	# activated
I8	shutter	0	# open	1	# closed
I9	interlock	0	# open	1	# closed
I10	operating mode	0	# remove	1	# centrifuge
O7	interlock	0	# closed	1	# open

List of programs:
N001: ACCEL 10 000	;sets the accelerating and braking ramps to 10s
N002: IF I8=1 GOTO locks (5)	;checks whether the shutter is closed
N003: OUTPUT O7=1	;opens interlock
N004: IF I8=0 GOTO 4	;waits until the shutter is closed
Lock:	;mark
N005: OUTPUT O7=0	;closes interlock
N006: IF I9=0 GOTO 6	;checks whether interlock is closed
Operating mode query:
N007: IF I10=1 GOTO centrifuges (18)	;queries operating mode switch
Remove:	;mark
N008: SPEED 0.1	;sets the speed to 0.1%
N009: WAIT 500	;waits 500 ms
N010: IF I7=0 GOTO 10	;waits until the light barrier is activated
N011: SPEED 0	;sets the speed to 0
N012: OUTPUT O7=1	;opens interlock
N013: IF I8=1 GOTO 13	;waits until shutter is opened
N014: IF I8=0 GOTO 14	;waits until shutter is closed again
N015: OUTPUT O7=0	;closes interlock
N016: IF I9=0 GOTO 16	;checks whether interlock is closed
N017: GOTO operating mode query (7)	;goes to data record N007
Centrifuge:	;mark
N018: SPEED 100	;sets speed to 100%
N019: IF I10=0 GOTO removing (8)	;operating mode query
N020: GOTO 19	;goes to data record N019
