Setup of belt tension adjustment

(14) Mount indicator electrode on driven shaft, and check that indicator electrode is not

contacting the base.

(Note) If the indicator electrode is contacting the base, or if the hole in the center of the base and the center of the indicator

electrode are not aligned, loose the four screws on the motor mounting base and adjust.

(15) Remount counter electrode, reconnect wiring in place, and fix clamp.

This completes the replacement procedure. Feed power to RC400G. Check that the drive

shaft/drive belt/driven shaft rotates smoothly and there is no abnormal noise like vibration or

intermittent sound.

Inspection, Maintenance and Replacement of Motor

Assembly/Gear Head

Inspection and Maintenance Procedure

With the electrode mechanism block working at the time of, for example, zero calibration, the

following inspections should be conducted. The recommended interval is three month.

• Check there’s no irregularity in rotation speed of drive shaft. If there’s any irregularity, loose

the load on the shaft by loosening the screws which fix the driven shaft pulley, and recheck.

If there is still irregularity, replace motor assembly and gear head. If the irregularity doesn’t

reappear, check the driven shaft assembly.

• Abnormal sound from gear head (motor).

If there’s any abnormal sound, check the motor assembly / gear head. (In principle, this

should be done by Yokogawa).

The following inspection should be performed approximately every six months.

• Motor rated torque and drive torque.

In <CELL> mode, when motor is turned ON/OFF, after the ON command it should quickly

reach speed. Confirm that the difference in speed of rotation between its normal status, and

when load is reduced by loosening screws fixing pulley to driven shaft, is not noticeable.

If operation is still not satisfactory, replace motor assembly and gear head.

Replacement Procedure

Replacement of the motor assembly/gear head, in principle, should be conducted by Yokogawa.

If the replacement is conducted by the user, the following should be noted.

• In principle, replace motor assembly and gear head at the same time as periodic

replacement of other parts. Replace complete motor assembly consisting of both motor and

capacitor.

• When replacing motor assembly and gear head, first remove motor mounting plate from

base.

There are no special cautions relating to removal of, or reassembly of, motor assembly and

gear head, however the parts such as electrode, rotating contact and drive belt removed

when removing motor assembly from mounting plate should be carefully reassembled,

referring to 8.10.1 through 8.10.3, so as not to make any mistakes in reassembly.

• The terminal board within motor assembly should be set same position of “C1” and “C2 ”

printed on the plate, which wire color of “C1” is yellow/green and “C2” is pink/black.
