Replacing Consumable Parts >> Servo Amplifier Battery
MEC-CP842-1.0E 6-23
Procedure
Replace the servo amplifier battery with the machine power on.
1 Verify that the machine's [SYSTEM ON] lamp is on.
2 Press the EMERGENCY STOP button. This disables the 200V power supply.
3 Identify the servo amplifier where "A.83" is displayed at the LED.
4 Locate the battery in the case located at the upper front of the servo amplifier
and replace it with a new battery.
CP-842E/842ME machines use the following 2 battery types in servo amplifiers
• Servo amplifier capacity: 30w to 5kw
Model: JZSP-BA01
• Servo amplifier capacity: 6kw, 7.5kw
Model: JZSP-BA01-01
Caution:The absolute encoder data will be lost If the old battery is removed while the servo amplifier
power LED is off. Ensure that the power LED is on before removing the old battery
5 Turn the machine power off. Reboot the machine, and verify that the "A.83"
alarm has cleared.
6 Press the [READY ON] switch to turn on the servo (200V) power. If machine
status is normal, then the procedure is complete.
WARNING
Press EMERGENCY STOP before performing this procedure.

6.11 Replacing the Carrier Clamp/Unclamp Air
Cylinder Packings
Point
Replace these packings if a carrier air cylinder is not working properly.
Procedure
1 Close the air inlet valve lever and remove the air hose. Next, gradually open the
valve lever to release the air pressure.
2 Remove the 4 bolts to remove the air cylinder from the in- or out-carrier bracket.
3 Disconnect the air hoses and remove the forward limit sensor.
Note Make a note of the air hose connections before disconnecting them, in order to prevent
reconnecting them in the wrong positions.
4 Loosen the locknut at the end of the piston rod (for type A cylinders), and
remove the bolt.
WARNING
Press EMERGENCY STOP before performing this procedure.

5 Use a snap-ring pliers to remove the snap-ring from the cylinder.
6 Remove the piston rod, and then remove the rod cover from the piston rod.
Note Do not force the rod cover off if it does not slide off the end of the piston rod smoothly.
Remove any burrs from the beveled end with a whetstone or sandpaper.
7 Remove the packings from the rod cover and piston rod.
8 Clean the rod cover, piston rod, and cylinder tube.
9 Apply Daphne Eponex No. 2 grease uniformly to the rod and piston packings,
and then mounting them in the rod cover and on the piston rod.
Note Do not damage or twist the packings when mounting them. Also, the packings are directional,
so be sure to mount them in the correct orientation.
