The TSM4000 sensor cable is guaranteed to be up to 30m long.

Any longer than this will be susceptible to external disturbances, which will affect accuracy and will be unacceptable.

The TSM4000 I/O cable is guaranteed to be up to 3m long.

Lengths of 3m or more are not supported.

This is useful as a reference, but it is not accurate because the current is not proportional.

If accuracy is required, you will need to actually measure and compare using a power meter.

Shock Monitor displays current and voltage as waveforms (sine waves), processes them as vector calculations, and displays the results as power.

There is no doubt that 5 is "+" and 12 is "-".

Special-shaped products are also not available.

It calculates power but does not output relays.

If connected to the primary side of the inverter, power cannot be detected correctly.

Please use it by wiring it to the secondary side of the inverter.

The allowable power supply voltage for the TSM4000 is 500V.

Considering that power supply voltage generally fluctuates by ±10%, the voltage becomes 480V x 1.1 = 528V, which exceeds the allowable value and is therefore unusable.

Special-sized products (high frequency specifications) are available.

There is no upper limit on frequency, but it depends on your usage conditions.

Also, accuracy decreases above 120Hz.

For small single-phase motors, the difference between the rated current and no-load current is small, making it difficult to detect if the current is set lower than the rated current.

The assumption is that the current change will be large.

In the case of small motors, the current value is small and it is necessary to increase the number of through-holes, but this may not be physically possible.

For example, if you set it to "5",

1st time: average of 1 to 5

2nd time: average of 2 to 6

3rd time: average of 3 to 7

The load to be averaged moves in this way.

If a momentary power outage lasts less than 0.1 seconds, operation will continue without any problems and monitoring and relay output can be maintained.

Even if there is a change in the motor voltage or current due to a momentary power outage, it will continue to function as a normal load monitor.

If there is a power outage of 0.1 seconds or more, the power to Shock Monitor may be cut off, in which case monitoring will be disabled and the relay output will also be restored.

After the power outage is resolved, the CPU will return to normal monitoring mode after the initial time has elapsed.

Doubling the number of turns on the current sensor will double the load factor display.

There is a specification that coats the printed circuit board of the product body.

If you are concerned about humidity during tropical travel, we recommend using a moisture-proofing agent such as silica gel.

The detection accuracy is ±2%.

The power factor changes depending on the motor load factor.

Shock Monitor does not directly detect the power factor, but calculates the power factor as a result of power calculation.

Torque monitoring is not required when using an inverter.

When changing the frequency, the setting value can also be changed using the process switching function, so we understand that it is often used for power monitoring.

With torque monitoring, accuracy drops significantly at low frequencies, so when used in that range, careful attention must be paid to the setting values; in that case, I think power monitoring would be easier to set.

Although it is not mentioned in the catalog or Instruction Manuals, it is possible.

Only when the I/O cable is connected, approximately 5V will be output while you are holding down the SET button on the H1 Trip in test mode.

While you are holding down the "SET button" on the H2 Trip, approximately 10V will be output.

CR surge absorber.
This surge absorber combines a capacitor (C) and a resistor (R).

The current flowing is about 2mA, so I think 0.5sq is sufficient.

*If you use wire that is too thin, it may break, so a certain thickness is necessary.

Power consumption is 10VA.

The bottom dimension of the main unit may interfere with the I/O cable when used, so in that case, a space of 10 cm must be left.

If you are not using the I/O cable, 1cm above and below is sufficient.

It's okay if High2 is lower.

The concept behind both Shock Relay and Shock Monitor is the same, it's just not stated.

If the minimum applicable load is not met, a low current relay is required.

When driving a motor, the torque is usually positive, but in the case of an elevator, for example, the torque is positive when going up but negative when going down.

When descending, the motor does not output force, but rather rotates while braking itself to prevent slipping, resulting in negative torque.

(Example) When suddenly decelerating in inverter operation

(Example) When driving while being pulled by a load

It is not recommended to use Shock Monitor when an AC reactor is installed on the secondary side of the inverter. The secondary side voltage may fluctuate and cause damage.

Please install the AC reactor on the primary side and Shock Monitor on the secondary side.

Even the basic model can be installed using panel mounting brackets.

However, the socket terminals will be facing in the opposite direction, making wiring more difficult.

No. If the setting is changed after shipping, the customer will not know that the setting has been changed, which may cause problems.

1.TSM4-PR2 is a CE compliant product.

* Shock Monitor itself must also be CE compliant.

2. The external dimensions are the same, but the internal resistance is different: PR1 is 100kΩ, and PR2 is 300kΩ.

3. The internal resistance is different, so if you combine them incorrectly, it may cause burning.

The two are different; the voltage doubler resistor is an option exclusive to Shock Monitor and is not a type of transformer, and the pressure reducing transformer cannot be used with Shock Monitor.

Yes, but Shock Monitor requires a DC24V power supply voltage.

Although CE declaration is not required for current sensors, if a voltage doubler resistor is required, please use the CE-compliant TSM4-PR2 (quote item).

CCC certification is not supported.

All TSM4000 models do not comply with UL standards.
