9. Connection Method / Instruction Manual
Operation for Direct Output Vibration Pick-up is as below figure 1.
Fig.1 Example of Connection method
Caution on cable connection and instruction
(1) Confirm “+” and “–” polarity first. If the polarity is opposite, sensor cannot operate.
(2) Do not supply power voltage more than the specification. It will cause breakdown on sensor.
(3) Shield wire (Silver) connect on minus side of power supply.
(4) In case of using any receiver such as logger with 1-5V, connect 250Ω resistance with it in
parallel.
(5) When relaying cables, be sure to use cable junction box. Also, take measures to prevent
disturbance noise from entering. If noise countermeasures are not implemented, correct
measurement results may not be obtained.
10. Warranty
If there is any breakdown caused by producing error, material fault, or obviously our fault, we
repair or exchange with no charge. This condition is valid only in warranty term and the term is for 1
year after delivered. However, even if it is under warranty, it will occur some charge on exchanging.
(A) Any damage and breakdown caused by natural disaster such as fire, earthquake, flood,
lightning damage.
(B) Any transporting, moving, or dropping which does not related us after finishing our
delivery.
(C) Any error operation, unusual power supply input, and the fault caused by
disassembling/repairing/modifying by customer.
