[CHAPTER 8]
MTU6 Adjustment
Note: Cut the power to the machine before connecting the MTU. If the by-pass key is
inserted in the mechanical switch of the MFU specifications safety door, remove
the key and put it in the MTU cover. If the key is left inserted in the MFU
specifications switch this will disable the MTU front safety door by-pass key
which can lead to damage.
[8-1] Prior to Adjusting the MTU6
- Since layered stacking of trays is not possible on the MTU6, the number of part types that can be
loaded increases to between 50 and 100 types in comparison to the MTU7 (MTU7 can handle from
10 to 20 part types).
- On modules that use the MTU6 it is possible to switch from an MTU6 to MFU and vice versa.
When changing from an MTU6 to an MFU, safety fence replacement work is also included. Check
the specification manual and be aware that if this option is included a spare fence will also be
shipped. When an MTU6 is installed on an MFU module, in some instances Proper data
measurement will be necessary.
- When an MTU6 unit is connected to the machine, it must be connected with the machine in the
zero set complete status. Also verify that the shuttle jaw and tray holder do not interfere with each
other.
- When disengaging an MTU6 unit from the machine, separate the shuttle jaw and tray holder and
also verify that the shuttle is advanced forward before beginning work. The shuttle may be
damaged if it is at the retract limit. (Remove after carrying out the magazine replacement
command operation [POSITION], [MTU], [EXCHG MAG.], and press START.)

[8-2] Timer Adjustment
Remove the MTU6 lower control box cover and set the timer on the relay board
positioned on the left side to "0.4".

Tray Storage Check Sensor Amp and Controller Settings
1) Tray storage check sensor amp settings
- If there are two amps with a controller attached then set MODE to "5".
If there is one amp and no controller then set MODE to "1".
- For MODE 1 setting, turn the SENS volume until the red and blue lamps both go
out. Next turn the volume back until both lamps light up. Set the volume back
one scale graduation further from that level.
For MODE 5, first turn the volume until the red lamp lights up then turn the
volume back until the blue lamp lights up.
Turn the volume back one more scale graduation from that level and set there.
- Set the Time volume to Min. (0.04).
2) Tray storage check sensor controller settings

[8-5] TZ-axis and TY-axis Timing Belt Removal
1) Open the MTU safety door and loosen the belt tension adjustment pulley.
2) Remove the lower rear cover and then remove the TZ-axis belt.
3) Loosen the TY-axis belt tension adjustment pulley located on the shuttle and then
remove the belt.

MTU Provisional Connection
1) Shuttle assembly
Set the shuttle assembly using the MFU set jig positioning pin and then secure the
assembly to the machine using the knurled screw on the assembly side. After
securing in place connect the cable that protrudes from the shuttle assembly to the
machine.
2) MTU reject parts conveyor
Adjust before loading the reject parts conveyor on the MTU. (Refer to chapter 11) Set the MTU
reject parts conveyor with the conveyor inserted in the two conveyor positioning pins located
on the assembly side. After the conveyor is set, secure it in place using the torque clamp
located on the assembly side and connect the cable to the lower front fence.
3) MTU provisional connection
Since zero set adjustment cannot be performed if the MTU is connected to the
machine, use extension cords to temporarily connect the MTU power and signal
cables only. Provisionally position the MTU diagonal to the machine so that work
can be performed at the rear of the MTU.
