Wiring
Warning
1. Preparation for wiring
Shut off the power before wiring (including
insertion and removal of connectors). Mount a
protective cover on the terminal block after
wiring.
2. Check the power
Make sure the power has sufficient capacity and
voltages are within the specified range before
wiring.
3. Grounding
Ground terminal block F.G. (Frame Ground).
Do not ground it with devices generating strong
electromagnetic noise.
4. Check wiring
Incorrect wiring may cause damage or
malfunction of the products. Make sure the
wiring is correct before operation.
Caution
1. Separation of signal wires from power wire
Avoid common or parallel wiring of signal and
power wires to prevent malfunction due to noise.
2. Wiring arrangement and fixation
Avoid bending cables sharply at connector part
or electrical entry in wiring arrangement.
Inproper arrangement may cause disconnection
which in turn causes malfunction. Fix cables
close enough not to give excessive force to the
connector.
Piping
Caution
1. Before piping
Remove cutting chips, cutting oil, dust, etc. in
piping by flushing or cleaning before piping.
Care should be taken especially that any cutting
chips, cutting oil, dust, etc. do not exist after a
filter.
2. At piping
①
Foreign matter should not enter. Entering of
foreign matter will cause malfunction.
②
Cutting chips and sealing materials at piping
threads should not enter valves when piping
and fittings are screwed in. Leave 1.5 to 2
threads when seal tape is used.
Lubrication
Caution
1. Lubrication of cylinder
①
This cylinder is pre-lubricated and can be used
without lubrication.
②
In case of lubrication, use a equivalent of the
turbine oil type 1 ISO VG32. Once lubrication
is performed, it should be continued since the
initial lubricant flows out causing malfunction.
Adjustment
Caution
1. The locks are manually disengaged when the
cylinder is shipped from the factory. Be sure to
change them to the locked state before using
the cylinder.
2. Adjust the cylinder
’s air balance. In the state in
which a load is attached to the cylinder,
disengage the lock and adjust the air pressure
on the rod side and the head side of the cylinder
to obtain a load balance. By maintaining a
proper air balance, the piston rod can be
prevented from lurching when the lock is
disengaged.
3. Adjust the mounting position of detection
devices such as autoswitches.
Sensor unit
Caution
1. Do not remove the sensor unit.
The position and sensitivity of the sensor is
adjusted properly before shipment.
Removing or replacing the sensor may cause
malfunction.
2. Operate the system with an external magnetic
field of 14.5mT or less.
Strong magnetic field in the vicinity may cause
malfunction, since CE2 sensor is magnetic type.
This is equivalent to a magnetic field of
approximately 18cm in radius from a welding area
using a welding current of almost 15,000 amperes.
To use the system in a magnetic field that exceeds
this value, use a magnetic material to shield the
sensor unit
