TMUTOYO KEIKI

Multi-power meter

If you use this “TMU” multi-meter, you can measure 20 elements on the main display,and 17 elements on the sub-display.

TOYOKEIKI CO., LTD.
CAT.No. TMU-01E

Feature◆Package display (4 elements)
23 elements can be displayed on the screen.
High-speed digital operation system is adopted.
Many elements are displayed on real time 1 screen with the
combination by LCD display. Even when there is no lighting,it displays clearly with backlight.
◆The same attachment as 110 wide angle meter.
It possible to replace, since it is the same size. (110type)◆It possible to measure active energy and reactive energy of out
going and in coming.
◆Harmonic measurement.
It possible to measure voltage distortion factor and current
distortion factor.
◆It possible to measure 4 times rated current.
Also in consideration of inrush current, it possible to measure
up to 4 times of rated input current.
◆Bar graph of possible scaling.
The bar graph can be scaling scaled.

・It is allowed to display watt-hour, var-hour and operatingtime only on 1st sud-display.
・It is allowed to display max demand only 1st sub-display and min demand only 2nd sub-display.
・In the case of 1P2W you select either PAT 0 on user’s pattern.

Watt-hour and var-hour digit feeding(If you want to check the detail (under decimal point) of Watt-hour and var-hour, you can check it by the method as follow.)① Select the measurement on main display. (watt-hour or var-hour)② While pushing both ＋ and − keys at the same time allows to feed the digit readout 6 to 9 digit. After detached the key, it will return to a normal display.

Installation and wiring
Check of aproductSpecifications of inputs, an auxiliary power supply, and outputs are marked on the product. Please check that it is in agreement with the specification of yourdemand.
Installation environment
Installation environment influences the performance of a product. Please refer to the following and select installation environment.
① Surrounding temperature, humidity.
Please avoid high temperature, a humind if possible, in any at the time of transportation, storage and use.
② Please avoid a continuous vibration and a shock in the use.
③ When used in a special environment, please contact our.
Installation① Attachment position
The display screen of this product is using the liquid-crystal-display(LCD).
A LCD changes contrast with the angle to see. We prepare the two type LCDwith the different angle to see.
Please determine selection of type and an installation position for the rightfigure as reference.
Instrument screen of viewing angle to upper is advantageous to install in aposition a little higher than eye-level in respect of contrast. And instrument
screen of viewing angle to lower is advantageous to install in a position a little
lower than eye-level in respect of contrast.
② Installation
Please attach by referring to the panel cut of an outside size (＊＊page ), andprocess a hole.
When you attach adjacently, please take 115mm leftward, take the interval of
125mm or more in the vertical direction.
The depth direction should take a margin in consideration of the drawer of acable.
Connection
Please connect correctly according to a connection figure.
① If it is made to rotate counterclockwise, it will separate from a terminal cover.
After a connection end should attach a terminal cover as before.
As for the terminal cover , the vertical direction was decided. Please attach in the direction which can read a terminal number correctly.
② In an input terminal and a power supply terminal, the object for M4 and an output terminal should prepare the object for M3.
③ It is recommended that one of CT’s, VT’s secondary terminals should ground for safety (refer to wiring fig).
④ Be sure to ground an earth terminal(No.7 terminal) for safety and stability of operation.
⑤ In the case of product with DC 24V power supply, it has polarity in the auxiliary powerterminal. If you are connected on the contrary, it does not power on.
⑥ Please take a margin for cable diameter. You need to select a cable that is permitted for overcurrent.

― 15 ―

⑦ In the case of product with outputs, please dissociate output wiring from wiring to
inputs, a power supply, a power line, etc., and wiring for output signal should use
shielding wire or twisted pair wire if needed.
⑧ External remote(or reset) inputs operate by impressing voltage.
Please prepare the power supply of AC 80-264V or DC 80-143V.
An auxiliary power supply can be used commonly. The internal structure is as follows.
When not using a reset terminal, leave open circuit. The consumption current of theremote input is about 1mA at 100V a.c. or dc..

Terminal number
external remote input : 20, 21
reset input: 16, 17

⑨ An alarm output’circuit is following. Please use it within the rated voltage andcurrent, and if necessary, use surge absorb devices in external.
⑩ Please connect nothing to non-connection terminals. When you do not use an output terminal and/or a remote terminal, Please leave to opening. For the
product has current output, if you do not use the output, it is not necessary to connect together. When a product with a digital transmission output which
does not use, please leave to opening.
⑪ Connection should check having tightened the screw certainly and it should surely a terminal cover.
Troubleshooting information when a trouble occurs, please check the following table to reference.
Condition

Check point

It is hard to see a display.

① The liquid-crystal-display(LCD) is used a display. A LCD has a thing hard to see depending on the direction to see.
It is designed so that it may become legible towards looking up at the front of the display.
On the contrary, towards looking down, it becomes a little hard to see.
② The contrast of LCD worsens in the environment where temperature is high(45 degrees C or more). I will recover, if
temperature falls.

A display blinks.

If an input value exceeds the set point of a setting indicator, a display will blink. Please check the set point.

The back light went off.

ERROR01 had been displayed.
ERROR02 had been displayed.
ERROR03 had been displayed.

If you push the DISPLAY key switch, dose a back light turn on?
A back light can be chosen from the following mode by initial setting.
・The light is turned on at all times.
・A back light does not use it.
・The light is switched on for 3 minutes after key operation, and turn off automatically.
In setting change, please see the 13.Back light
