８-８. Setting the work clamp mode

Through the combination of DIP switches A-1 and A-2 on the operation panel, presser motions can be set as follows:

[Setting solenoid work clamp mode]
DIPA-1	DIPA-2	Pedal specifications		Raising the presser at the sewing end
-	-	Single pedal	Work	clamp	is raised	automatically.	(factory	default
			settings)
ON	-	Single pedal	Work clamp is raised by pressing the pedal.
-	ON	Two pedals	Work clamp is raised automatically, then it is lowered by
			pressing the pedal.
ON	ON	Two pedals	Work clamp is kept lifted while the work clamp pedal						is
			pressed.
[Setting pneumatic work clamp mode]
memo-42=0 (memo-3b=0: KE-436B, 436C) <initial value>
DIPA-1	DIPA-2	Pedal specifications		Raising the presser at the sewing end
-	ON	Single pedal	Work clamp is raised automatically.
ON	ON	Single pedal	Work clamp is raised by pressing the pedal.
-	-	Two pedals	Work	clamp is	raised automatically, then		it is lowered		by
			pressing the pedal. (factory default settings)
ON	-	Two pedals	Work	clamp is	kept lifted	while the work	clamp	pedal	is
			pressed.

Special memo-42 settings (memo-3b: KE-436B, 436C)

memo-42	Pedal	Raising the presser at the sewing end
memo-3b	specifications
		Left presser drops when presser pedal is at the 1st step, and right presser drops
		when presser pedal is at the 2nd step.
5	Two pedals	Raising is carried out in the reverse order.
		* Initial value for inner clamping specifications only
		* Setting used when using the light work clamp function (Refer to “1-8-3. Light
		work clamp”.)
6		Right presser drops when presser pedal is at the 1st step, and left presser drops
	Two pedals	when presser pedal is at the 2nd step.
		Raising is carried out in the reverse order.
		The left/right operating sequence changes alternately for each item sewn when
7	Two pedals	using two-pedal operation.
		Starts with right → left.
		The left pedal is used to raise and lower the left presser, and the right (center) pedal
		is used to raise and lower the right presser.
8	Three pedals	The start (right) pedal is used to start sewing.
	(Option)	Furthermore, when DIP switch A-2 is at ON, and if one presser is already lowered,
		pressing the start pedal causes the other presser to be lowered and then sewing
		starts.
9		When the presser pedal is depressed to the 1st step, both left and right pressers are
	Two pedals	raised simultaneously.
		When it is pressed to the 2nd step, sewing starts.
10		When the start pedal is depressed, both left and right pressers are lowered
	Two pedals	simultaneously.
		When the start pedal is released, sewing starts.
	Three pedals	The left pedal raises and lowers the left and right work clamps, and the right pedal
11		(center) detects the home position. The start (right) pedal is used to start sewing.
	(Option)	For the stepping foot specifications, both work clamps are lowered when DIP switch
		A-2 is ON, and the stepping foot is also lowered at the same time.
		The left pedal raises and lowers the left work clamp, and the right pedal (center)
		detects the home position. When the start pedal (right side) is depressed for a short
12	Three pedals	time (200 ms), the right work clamp is lowered, and when it is depressed for a longer
	(Option)	time the right work clamp is lowered and then sewing starts.
		For the stepping foot specifications, the right work clamp is lowered when DIP switch
		A-2 is ON, and the stepping foot is also lowered at the same time.
13	Two pedals	Two-pedal operation raises and lowers the left and right work clamps
		simultaneously, and the stepping foot is lowered at the sewing start.

When memo-42 (memo-3b) has been used to make a special setting, DIP switches A-1 and A-2 function as follows.

∙When DIP switch A-1 is at ON, the work clamp are not raised automatically at the sewing end.

∙DIP switch A-2 is ignored except when memo-42 (memo-3b) = 8, 11, 12.
