the abnormal situation results from the timing belt or pulley, please notify the local distributor
for maintenance or parts replacement.
10.2.3 Rotary joint
When measurement is abnormal, please turn off the power of the instrument, loosen the lower
electrode wiring of 6PIN terminal block(
○
1
Brown thick wire and
○
2
Red thick wire), and take
apart upper plastic signal connector from the rotary joint set. Measure the plastic signal
connector by a multimeter. Under normal circumstances, the two channels of the signal
connector should be insulation, and the resistance of the same channel upper and lower
connecting point should be less than 1
Ω . If there is abnormality, please notify the local
distributor for maintenance or parts replacement.
10.2.4 Bearing with housing
When the electrode rotation speed is abnormal , or when abnormal sound occurs during rotation,
please check whether if the bearing of the bearing with housing works normally. If the
abnormal situation results from the bearing with housing, please notify the local distributor for
maintenance or parts replacement.
10.3 Flow-through chamber
It is recommended to clean the flow-through chamber regularly in order to prevent from dirt or
other impurities from affecting the measurement results. When cleaning, please turn off the
motor function from setting, and then lift up the sensor box, move it right, and put down to
hang on the support columns of the supporting plate.(Please refer to Ch 2.2.1 for illustration of
Installation dimensions.) This helps for clean the free Cl
2
electrode, pH electrode(optional), pH
electrode housing(optional), and the surface of temperature probe. Then, take out the measuring
cup, and pour out the ceramic beads in order to clean both of them. Users may consider to
remove the four piping connectors which are under the flow-through chamber, and apply
suitable size long brush to scrub the chamber. After cleaning, wrap some sealing tape around
the connectors thread and screw up the connectors to the flow-through chamber. When the
flow-through chamber is really necessary to be took apart from the supporting plate, be careful
to control the force to avoid damaging the acrylic thread hole
