Precautions for Correct Use
Precautions for Correct Use
Observe the following operating methods to prevent failure and malfunction.
The followings are common to the K6CM.
(1) Use the power supply voltage, input power, and other power supplies and transformers with suit-
able capacities and rated outputs.
(2) When cleaning the product, do not use thinners or solvents. Use commercial alcohol.
(3) Confirm that wire does not stick up after wiring of stranded cable.
(4) In case of passage wiring, install these by 10 A per 1 terminal because when products are con-
nected more than one in parallel, quite many electric currents to be called off.
(5) The terminal block may be damaged if specialized tool is not used. Use a recommended flat-blade
screwdriver to inserted into a release hole on the terminal block.
(6) Do not apply excessive force to bend or pull the communications cables, and do not place heavy
objects on the cables. Doing so will damage the cables.
(7) Refer to the status information of the product on the data link communication and refer to the
received data only in case of no errors occur with the product.
The followings are for K6CM-VB and K6CM-VBS1 sensors.
(8) Wipe off the dirt on the mounting surface and screw mounting with 17 mm nominal size of wrench.
• Recommended mounting screw tightening torque: 4.4 to 5.4 N•m
• Mounting hole dimension: M6 holes (depth: 9 mm min.)
(9) The easy-positioning magnet is for the purpose of seeking the detected position. In the case of
using the product permanently, be sure to use it after it is mounted by screws.
(10) In the case of vertical mounting or reverse mounting with the easy positioning magnet, be careful
of the sensor falling.
(11) Refer to Installation of the Vibration Sensor Head on page 5-7 to install the sensor correctly. It may
be impossible to detect high frequency vibration.
(12) Do not disassemble the sensor. It may not operate correctly.
(13) Be careful of incorrect wiring or short circuit for wiring.
(14) Do not use the preamplifier connected to the other products.
(15) If there is a vibration reduction device such as dampers and rubbers between the vibration mea-
surement object and the sensor, it is difficult to detect the vibration and it will not be able to mea-
sure it correctly, so do not install as much as possible.
(16) In the case of insertion and removal of connector, be sure to do it by holding the connector with
hands.
(17) Do not remove the connector with holding the cable.
(18) Check the direction of the key groove before you use the connector.
(19) Do not wire with wet hands. It may result in operation failure or product damage when power is
being supplied to the product.
(20) When fitting the connector, be sure to do it with hands, not to use tools. It may result in damages if
the tool like plier is used.
(21) In the case of removal of the fitness of the connector between the sensor and the preamplifier, be
careful to do it not to adhere water or dirt on the fitting surface. It may result in faulty contact at the
connector.
(22) Install cables to avoid any force is applied to the connector. In case the any force is applied to the
connector, it causes that the performance of protection structure (IP67G) becomes incapable.
(23) Do not use the connector as a scaffold or put heavy objects on it. It may result in connector dam-
age.
