The earth of the rack is reinforced.
The earth is defective
in the rack where stator
was installed.
Inform
us
about the contents of
failure and situation at site in details.
＜
For earth reinforcement of rack
＞
A defective earth of the rack where stator was installed is thought as a change cause of the voltage
output. Especially, there is a possibility to be generated by the influence of the inverter noise by a
defective earth when it is an inverter motor etc. and a common rack.
Please execute the reinforcement of the earth of the rack where stator was installed.
Moreover, the influence of the inverter noise might be decreased by floating the stator from the
rack using the insulating material electrically.
＜
For maintenance of fan motor
＞
When this product is used under the environment of the oil mist, there is a thing which fan motor
stops because of oil and dust.
A serious problem which leads to the breakdown occurs if fan motor stops.
Please execute the maintenance of fan motor once a year.
＜
For the voltage output and current output
＞
Connecting of the instrument with the stator (In the case of the stator is grounded.) makes the
voltage output (
−
) and current output (
−
) to the same potential as the ground potential.
When you make a connection with other instrument with the + voltage output and
−
voltage in
adverse, so as to obtain an opposite output polarity of Torque transducer, but the voltage output of
the instrument will become short and the output will not change in the case that
−
terminal at the
side of measuring instrument is the same potential with the ground.
When you want to adopt such method, we recommend to insert an isolator at the output section of
the instrument.
