8.2.3.1 The clamping signal is from the clamping proximate of the turret
and the clamping proximate is the NC PNP switch and it is high lever
effective and it，s output current is 200mA.

8.2.3.3 Signaling disc：There are two signaling disc in our company one is
the high lever effective signaling disc and it is used for high lever effective
CNC system and other is the lower lever effective signaling disc and it is
used for lower lever effective CNC system.
8.2.3.4 8421 coder：It is NO PNP output device and it is used 24 VDC
power and it，s output current is 25 mA.
8.2.4 NOTE：
8.2.4.1 Do not with the signaling output terminal or proximate output
terminal or proximate output terminal and electrode of the power
short-circuiting.
8.2.4.2 It is must be close the power switch when you connecting the
coder terminal and the proximate output terminal.
8.2.4.3 Because the output device is used CMOS device so when you
connected from turret to CNC system the ground connecting of the electric
iron must be good.

9Installing and adjusting
9.1 Installing
When the turret is installing at frist the assemblies must be coating oil and
the driving system must be lubrication.
Make sure the fixing surface is clean and squared to ensure a proper tool
alignment. Align the front surface of the disc in order to have it
perpendicular to the spindle axis.
9.2 Adjusting
The electric connection must be carried out according to the 15T
diagram,The connection cable must be provided with fittings and gasket in
order to penetration of water into the turret.When the turret can not
indexing at this frist must be cutoff the power switch and detected phase of
the motor and then restarted ,when the turret indexing the turret must be
agile and no abnormal sound.
10 Use and maintenance
10.1 The back cap do not removed and every assembly do not changed.
10.2 Indexing frequency <6 cycle min
10.3 The CCW clamping time is equal to 0.8-1.0s.
10.4 Maintenance
10.4.1every day must be lubricating the mechanical part of the turret ,and
after tree month must be changed lubricate and coating the oil for the tool
disc.

11. FAULT,FINDING LIST, CORRECTION
Note：when adjusting the relative position of the .Hall unit and magnet the
Carrier must be locked and the position of .Hall unit must be 1/3 ahead
magnet steel.
FAULT
FINDING LIST
CORRECTION
1.motor can not start or
upper body can’t
rotation
1.phase inversion votage
is too low
cut off the power at once
adjust the phase and
voltage of the motor then
start agan.
2.upper body rotating
continually and can’t
stop.
1.signalling disc bad
contact .
2.signalling disc fault.
3.Hall unit is broken or
short.
4.pole of magnet steel is
inversion.
5.the position of the
magnet steel and .Hall
unit is relative departure.
6.the Hall unit or magnet
is bad.
Unload cover,checking
signalling disc and
supply ,adjust the
position of the magnet
and Hall unit .or replace
Hall unit .
3.after having
correctly perfomed
the indexing cycle
the disk stil unloked
1.the time of the CCW
so short.
2.bad contact.
3.with the locking
signal cut off the
CCW rotating signal.
Adjusting the time of
CCW,checking wire pf
the turret .can not with
the locking signal foe
the motor in CCW.
4.the disc goes on
rotating without
stopping or over.
the position of the
magnet and Hall unit
no good. Delay
between the CW and
CCW is no long.
Adjust the position of
the magnet and .Hall
unit and delay time
between the CW and
the CCW.
5.the face of the
workpice present
some ripple.
1.the turret is not
clamping.
2.fault of the
mechanical system.
Adjusted clamping time
(must be according to
the instruction of the
turret)

12.2Note：
12.2.1 When you dismantling the turret must be marked relatively position
of the assembly and do not attained sealed ring of the turret.
12.2.2 When you reassembling the turret it is must be make sure the fixing
surface is clean and have not dust or other material.
12.2.3 When you adjused coder at frist must be lock the turret at any
position and set an approximate positioning by rotating the unit to get the
corresponding position code or the signal passes from 1 to 0 and mark this
new position and tighten the screws of the fixing pieces.
