1 Introduction

6 6
By using the MAESTRO 2M PCB Separator, pre-scored PCB's are cleanly and economically separated.
Wear resistant blades and guides made from special steel ensure a long working life without adjustment.Adjustment
of the guides can be quickly and easily carried out.
The lower blade of the MAESTRO 2M is motor driven. The PCB is placed before the blades which then take hold
of the PCB, drawing it between them and thereby separating it. The machine can be used for a long period of
time without tiring the operator, and is therefore particularly suitable for processing large quantities of PCB's. The
motorized drive is regulated, thereby high separation performance is guaranteed.

Fig. 3 Connections
3.2.1 Earthing Connection
!
Attention!
Hazard by electrical charge !
Provide an earthing connection via press stud (8).
3.2.2 Power Connection
1. Ensure that the device is switched off at the power switch (3).
2. Check the setting of the voltage selector (4).
• In order to alter the setting open the ap at the power input module.
• Remove the voltage selector (4) and re-insert it so that the correct voltage is visible when module the ap is
closed.
• Upon altering the setting, the fuses in the module must also be changed accordingly (T500 mA for 230 V; T1,0A
for 115 V).
3. Connect the power cable to the power input module (2)
4. Connect the power cable to an earthed socket.

3.3 Height Adjustment of the Upper Blade
iNotice!
Toavoidpossibledamageonthebladesduringtransporttheupperblade(4)isxedinthe"Parkposition"
so that there is a maximum distance to the lower blade.
Set the upper blade into the working position before switching on the machine.

Fig. 4 Height adjustment of the upper blade
There is a scale (1) on the frame where you can see the height adjustment in steps of 1/10 mm. When you receive
the machine, the pointer (2) of the scale is in position "16".
1. Hold the knob (3) and loosen the knurled knob (6).
2. Rotate the knob (3) clockwise until stop.
Through that the upper blade (4) move down to the lower blade (5) until both blades are just touching one another
(lower end position). Make a notice of the position of the pointer (2) to use it for all further adjustments.
This lower end position locks the upper blade in place to prevent it from moving out of adjustment.
3. Move the knob (3) anti-clockwise until the pointer is in the middle position between the lower end position and the
position "16".
4. Tighten the knurled knob (6).
5. Run some test-cuts to check if it is possible to separate the PCB's. If it is not possible reduce the distance
between the blades in small steps.
iNotice!
The described adjustment helps to reduce the separation forces. This is important when sensitive compo-
nents are very close to the groove.
!Attention!
Before moving the machine to a new location, set the upper blade to the Park position.

3.4 Adjustment of the Stop of the Upper Blade
iNotice!
The lower stop of the upper blade adjustment is already adjusted by delivery.
After a long operation time, while working at strongly varying temperatures or else after replacing a
blade, it is recommended to re-adjust the lower stop.

Fig. 5 Adjustment of the stop of the upper blade
1. Hold the knob (7) and loosen the knurled knob (8).
2. Rotate the pointer (2) with the knob (7) anti-clockwise into position "16".
3. Loosen the cylinder screw (3).
4. Move the knob (7) clockwise until the upper and lower blades gently touch without overlapping.
5. Hold tight the knob (7) and tighten the knurled knob (8).
6. Swing the strut (6) clockwise until you reach the stop and tighten the cylinder screw (3). This adjustment locks the
upper blade in place to prevent it from moving out of adjustment.
7. Re-adjust the upper blade position 3.3 on page 8.
3.5 Upper Guide Adjustment
21
3
D
Fig. 6 Upper guide adjustment
1. Using a pre-scored PCB, check the clearance D between the guides (1,3). The clearance should be set so that
the edge of the upper guide is located correctly into the pre-scored groove of the PCB. The PCB can be smoothly
moved backwards and forwards but cannot move sideways.
The upper guide (1) prevent the PCB from slipping to the side and therefore ensures that it is not separated other
than at the pre-scored groove.
2. As required, the clearance D should be adjusted as described above by turning the eccentric adjusters (2).

4.2 Setting the Speed of Separation
iNotice!
The speed may be switched during operation as well as in Standby mode. In the latter case, the set speed
will be shown as long as the SPEED key (3) is being pressed.
Press the SPEED key (3) if necessary several times. The key may be reached with a pointed tool through the
hole (4).
The speed may be adjusted in three levels: Display "1": 100 mm/s
Display "2": 200 mm/s
Display "3": 300 mm/s
4.3 Separating the PCB's
!
Warning!
Risk of hand injury !
Wear protective gloves while PCB separating.
iNotice!
Whenusingthemachineforthersttime,degreasethebladeswithasoftcloth.
1. Press Start/Stop key (5).
The lower blade (10) starts to rotate at its preset speed. The preset speed will be shown at the display (2).
2. Lay the PCB (8) onto the lower guide (9).
3. Slide the PCB forwards between upper and lower guide (6,9) to the blades (7,10).
The rotating lower blade (10) will catch hold of the pre-scored PCB, which will be separated as it is transported
between the two blades.
4. In order to return to Standby mode, press the Start/Stop key. The motor will be switched off and the lower blade
will stop.
iNotice!
When the machine is switched off, it is possible to separate PCB’s manually.
Insert the PCB between upper and lower guide (6,9) and then push it gently between the blades (10,11 ).

4.4 Error Treatment
The device has an overload protection which will switch the motor off.
Error Message Cause Remedy
Display "F" Overload
• when trying to cut beside the pre-
scored groove
• when a component on a PCB are
jammed between the blades
The cutter drive will perform a short backward
movement and will then switch off within 0.5 s of
the overload occurring. The backward movement
relieves the removing of the jammed material.
Remove the jammed material.
Press the Start/Stop key.
The device switches to the standby mode
(Display "0").
Check both blades for any possible damage
before re-starting operation.

Fig. 8 Alignment of blades and guides
!Attention!
In order to ensure that the machine functions correctly, it is important that the surfaces of all parts shown
inthegure,ie.lowerguide(6),upperguide(3),andtheupperandlowerbladecovers(1,4)areexactlyin
line with the blades (2,5). This setting is achieved ex-works by placing washers between the machine frame
and the parts listed.
Only dismantle the above parts when absolutely necessary.
In such an event (eg. as a result of a very narrow side-strip removed from a PCB becoming jammed),
it is important that all washers removed are carefully put to one side. Upon reassembling the machine,
mount all parts with the concerning washers at the correct positions.
