Contactless Meter Relay
A precise meter relay that uses the deflection of the pointer to control the external circuits.
Toyo Keiki manufactures devices with photoelectric-type configurations.

■ Features of Meter Relay

Operation Mechanism of Contactless Meter Relay● These meter relays possess the various features of a contactlesssolid state relay.
● The relay circuits and detection relay are integrated into the main
body of the meter.
This reduces labor, potential misconnection and other issues in steps
such as connection and installation of the included cells.

While the standard output signal format of the meter relays is apassing signal retaining type, the following three types are used
for the MPV-11.
Compatible Meter Relay Format

Output Signal Format

Wide angle shape, square shape, edgewise shape(MPV type, MPC type, MPE type)● Highly reliable operation.

1. Passing Signal Retaining Type● Reliable operation even during minute meter input.

2. Passage Type/Instantaneous Type Wide Angle Shape (MPV type)● Set point passage-type relay.

3. Stop TypeOperating Principles of Photoelectric TypeA light source and a receiver are installed on the upper limit andlower limit pointers respectively. The collector current of the phototransistor receiver changes when the foil attached to the movable
pointer goes between the light source and the receiver by means of
the movable coil input. This change in current is converted to achange in voltage which passes through a comparator circuit and aswitching circuit to operate the detection relay.

L SideWide-angle Meter Relay
Photoelectric-type Circuit Configuration

4(1) When using a meter relay with L settings (except the wide
angle passing signal retaining type), take care not to turn on
the power of the meter relay and the meter input at the sametime, as the L side signal will be generated continuously until
the meter pointer passes the set L pointer.

Wide-angle Meter Relay (Passing Signal Retaining Type)
While 90° displacement meter relays have a shielding plate at the 90° point and can retain the signal by themselves after the pointer passes this,wide-angle meter relays are mechanically unable to do this because the displacement angle (240°) is too large. An electronic storage method isused instead.
As a result, the following issues occur the first time the auxiliary power supply is turned on. Please take this into account when designing circuits.
(1) When the Auxiliary Power Supply is Turned On (L Side Only)
Load relay operation on the L side should be turned on when the meter pointer is a zero and the auxiliary power supply is turned on, but in thiscase operation does not occur unless the pointer is displaced to around 17mm before the L setting value.
However, this only occurs the first time the pointer passes after turning on the power. After this, operation is turned off when the L setting value ispassed and on after returning to normal, and remains on after returning to zero.
This only occurs for the L setting. Normal operation occurs from the start for the H setting.
(2) When the Auxiliary Power Supply is Stopped
If the indicator input and auxiliary power supply of the meter are applied by different circuits, the auxiliary power supply stops when the pointergoes above the H setting value and the H load relay activates. If the pointer continues to indicate the same value, the H load relay returns (turns off)at the same time as the power supply, and usually turns back on when the power is turned on again.
However, if the power is off for 40 seconds or longer, the storage circuit no longer retains the signal, with the result that the previous signal is nolonger output when the power is turned on again. If the power is off for 40 seconds or longer, be sure to return the pointer to the zero position by
opening or shorting the meter input circuit.
No issue occurs when the power is off for short periods of less than 40 seconds, as the storage circuit remains live.

Note) Numerical values inside parentheses indicate values that deviate from JIS standards, but can be manufactured.

Using the Above Chart[1] For 3P wattmeters, 3P4W wattmeters and 1P3W wattmeters, the measurement range values are displayed in the voltage ratios (VTratio differences) and CT ratio differences in the table above. (There are three types defined for the same VT and CT ratios. Choose
the appropriate type. However, an item marked with * in the intrinsic power field needs to be selected for the wide angle meter.)E.g.) For a VT: 3300V/110V, CT: 100A/5A 3P wattmeter... select the appropriate one from 400kW, 500kW or 600kW from thetable above.
[2] For 1P wattmeters, 3P varmeters, and 3P4W varmeters, the values displayed above are multiplied by 1/2, and are multipliedby 1/4 for 1P varmeters.
Note 1) For varmeters, read kW units as kvar.

Example: For a VT: 3300V/110V, CT: 100A/5A 3P varmeter…LEAD2500~LAG250 kvar or LEAD300~0~LAG300 kvar(500 × 1/2)(500 × 1/2)(600 × 1/2)(600 × 1/2)

2) For 3P varmeters or 3P4W varmeters with zero left meters, follow the values as displayed above, and for1P varmeters with zero left meters, the values in the table above are multiplied by 1/2.
[3] If the CT ratio exceeds the range listed above, (for example, VT: 3300V/110V, CT: 5000A/5A 3P wattmeter) select a value from theCT: 500A/5A row (2MW, 2.5MW, 3MW) and multiply it by 10.
Note) In the situation above, scale indicators are 20MW, 25MW and 30MW. (It is preferable that the highest 3 digits of scales
are displayed.)[4] If CT ratios do not correspond with those indicated above (for example, CT: 60A/5A), use the calculation chart below to acquire themeasurement range, then choose from among them the value with the best ending number.
Measurement Range = Intrinsic Power × VT Ratio × CT Ratio
Note) Select a value indicated below from the intrinsic power value in the above calculation chart. However, intrinsic
power values vary depending on meter type. Use the multiplier indicated below to calculate the value.

Earth-resistance Meter Relay MPV-11, MPC-12[Overview]
This meter relay can measure the earth resistance value of a contactless AC circuit while also detecting
abnormal earth resistance values in the same circuit. Comprising a contactless meter relay and extra
power unit, this meter relay can be used for a wide range of purposes such as detecting abnormalities
in grounding accidents in settings such as boats.
A particularly useful feature is the fixed voltage circuit built into the extra power unit, which maintains aroughly fixed voltage circuit even during fluctuations of ±10% in the input voltage of AC115V, preventing
measurement error.
[Features]● Earth resistance measurements can be taken continuously while also setting anddetecting the desired earth resistance values on the scale of the photoelectric-type
detection setting mechanism, as well as activating warning equipment using therelay circuit contact.
● Lines can be measured and detected while live.

Apply an AC power supply to the extra power unit to generate DC50V on the output side.
This DC power supply can be used to combine the unit with a DC ammeter with an MΩ scale,making it possible to take measurements and read earth resistance for circuit currents thatchange depending on the ground status.
The AC side and output side of the extra unit are insulated by a transformer. This means thatthe DC power supply can be considered separate from the lines, creating the basic circuit
shown on the left.
In the circuit diagram on the left, DC50V is being generated by the power unit, the power isconnected to the meter in a series where Rs = 0.2 MΩ (scale centering on meter), and a
resistance value is being indicated.
When switch S is turned on, the pointer of the meter moves to the maximum, indicating
0MΩ in this case.

Stationary Non-indicating Regulator AS-62·DS-62<Solid State Relay>[Overview]
This product is a non-indicating adjustment meter with no meter drive unit. The AS-62 uses AC
input while the DS-62 uses DC input. The auxiliary power supply can be used for AC 100/110V
and AC 200/220V. This product can also be manufactured with a DC24V power supply. The
on/off status of the relay is shown by a red LED on the front, and the setting scale also has anextremely easy-to-see structure. Two attachment methods can be used: by connector or bypanel mounting. Panel mounting is done by connecting the lines using the terminal block on
the back (M4 screws). Compact design with front panel measuring 62.5x62.5.

6 Power Supply Circuit[Overview of Operation]
After amplifying the input signal with the input amplifier(U1), the entire wave is rectified and flattened with therectifier circuit (U2) and then input on the signal side withthe comparator circuit (U4).
Meanwhile, the voltage set by the dial is input on thesetting side with the setting circuit (U3). The output from(U4) is a VH or VL value depending on this input. This signal
is input into a relay drive transistor to turn the relay on andoff. Here, the delay circuit (U5) delays the signal from U4 foraround 1 second in the event of a signal delay. The circuit
constant differs depending on the specifications. In theevent of a power supply delay, the relay does not operate
for around 7 seconds after the power supply is turned on,even when the U4 output voltage is VH. This circuit
responds to the average input value, not DC components.

[Overview of Operation]
After amplifying the input signal with the input amplifier(U1), the signal is input on the signal side with thecomparator circuit (U3). Meanwhile, the voltage set by thedial is created by the setting circuit (U2) and input on thesetting side of the comparator circuit (U3). The output from(U4) is VH or VL depending on the relationship between
the signal and the setting value. This signal is input into arelay drive transistor to turn the relay on and off. The delay
circuit (U5) creates signals for power supply delays(approximately 7 seconds) and signal delays(approximately 1 second) according to the specifications.

Power Indicator AS-5-LI (Residual Current/Leakage Current Detector)[Overview]
This power indicator contains a highly reliable current relay that can detect low current settings. It detects
whether there is a 100mA current in circuits with a maximum current of 25A and generates a warning or
an indicator drive signal. This means that this device can be used together with a current transducer todetect power consumption of 10W in an AC100V circuit.
It can be used in centralized monitoring to detect electric leakage and power left on in high-rise buildings,
dormitories, hospitals and hotel rooms, reducing the workload for inspections and saving energy insecurity and safety measures.
[Features]● Highly reliable solid-state electronic parts.
● Lightweight, compact type.

(Main unit 100g, current transducer 200g)● Plugs into 8-pin socket, enabling easy security inspections and replacement.

[Purposes]● Detects small amounts of residual power and issues an alert.
● Detects electric leakage and issues an alert.
● Detector prevents power from being left switched on.

Special Anti-electric Resin Applied to Cover■ Precautions for Handling Meters● Be sure to note the following when handling, as the relay covers of the MPC and MPE-10 model meters are madefrom new materials.

A new type of resin cover with a betteranti-electric effect is used.
★The molded resin contains a special component that causes
self-discharge of static electricity.
This means that:
1) The anti-static effect is unaffected by the humidity of the operating
environment.
(The charge half-life is less than 1 second even in a relative humidity ofaround 23%)
2) The anti-static effect is semi-permanent in normal indoor operating
conditions.
3) Maintenance such as application of an anti-static finish is not needed.

● Avoid high temperature locations (60˚C or over)because the plastic cover and case of the meter are
easily affected by heat.

y
ra

Sp

● Maintenance with anti-static finish is not needed at all.
● To clean the surface, wipe gently with a light cloth.

● Do not apply solder directly to meter
terminals.

BenzineAlcohol

Paint

Thinner● The cover case may be damaged through contact
with chemicals (solvents such as paint thinner,benzine, alcohol, etc.).

22

Avoid direct sunlight and strong UV rays as much as possible.
(This may cause natural degradation in performance.)

The previous acrylic resin is used for the MPV and MPE-150 models.
Use an anti-static finish, particularly in poor conditions where static
electricity occurs easily, such as low humidity. [Anti-static finish:Anti-static 80S spray (from Tanaka Chemical Laboratory) orRiverson No. 30 spray (from Tokyo Yakuhin Kakosei)]~Promotion of Environmental Issues~
