Current transducers MCR-S-...-DCI

1. Before start-up

• When operating the electric measuring transducer, certain parts of the module can carry dangerous voltage. Ignoring the warnings can lead to serious injury and/or cause damage.
• The MCR-S-...DCI modules should only be installed and put into operation by qualified staff. The staff must have studied the warnings in these operating instructions thoroughly.
• Safe and trouble-free operation of this device can only be guaranteed if transport, storage and installation are carried out correctly and operation and maintenance are carried out with care.
• The measuring transducer may not be put into operation if the housing is open.
• Qualified staff as described in these operating instructions means those persons referred to as electricians or with an electro-technical training as defined in VDE 0105 Part 1/DIN EN 50110-1.

2. Description

The MCR-S-...-DCI, active current transducers convert direct, alternating and distorted currents from 0...0.2 A to 0...11 A (MCR-S-1-5-...-DCI) and from 0...9.5 A to 0...55 A (MCR-S-10-50-...-DCI) to analog standard signals.

On the output side, the analog standard signals of 0(4)...20 mA, 0(2)...10 V, ±10 V, 0(1)...5 V, ±5 V with simple (e.g. 0...10 V) and inverse (e.g. 10...0 V) signal flow direction can be used.

An option for the current transducers with threshold output (MCR-S-...-SW-DCI) is a PNP transistor switching output (80 mA) and a relay switching output (2 A).

2.1. Method of operation

Connecting to the input terminal blocks (MCR-S-1-5-...-DCI), or passing the live conductor through the current transducer (MCR-S-10-50-...-DCI) evokes a magnetic flow in the annular strip-wound core.

The density of magnetic flow is measured with the aid of a Hall sensor and converted proportionally from the input current to a voltage (Hall voltage). A downstream true r.m.s. converter enables DC, AC and distorted currents to be measured. The signal is amplified for further conditioning and made available at the output as a proportional analog signal.

4. Electrical connection and operation

4.1. Electrical connection

- When operating this electric measuring transducer, the national regulations (e.g. Germany VDE 0100 "Conditions for the erection of power installations with nominal voltages below 1000 volts") must be observed during installation and selection of the electrical conductors.

The following format applies only for MCR-S-10-50-...:

• The measuring line fed through the module has to feature at least basic insulation.
• Y : A wire voltage of 300 V AC or DC toward earth may not be exceeded on the measuring line!
• : With three-phase alternating current, a line voltage of 519.6 V may not be exceeded!

4.2. Start-up

Before putting this measuring transducer into operation, please ensure that the configuration data comply with the requirement.

The configuration data for a preconfigured device are to be found on the right hand side of the housing. When using a non-configured measuring transducer, a standard configuration that can be found in "7.1. Order key" is set.

Should the desired configuration not match that on the label on the side or the standard configuration, please observe the following point, "Functional diagram for configuration".

4.3.1. Selecting the appropriate measuring transducer

How to select the appropriate measuring transducer can be found in "2.2. Versions" or "7.1. Order Key".

The measured value must always be borne in mind:

0...0.2 A to 0...11 A (MCR-S-1-5-...) or

0...9.5 A to 0...55 A (MCR-S-10-50-...).

If in doubt, always choose the largest possible measuring range.

There is also one version with relay and transistor output for each module type (MCR-S-...-SW-DCI).

4.3.2. Configuring or programming

Using the MCR/PI-CONF-WIN software, the user has the possibility of freely programming the true r.m.s. value current transducer. Programming is described in the software manual. The convenient configuration software runs under all common windows operating systems.

In addition to the programming, modules can be parameterized using DIP switches and potentiometers.

In the rest of this chapter, the configuration is explained:

4.3.3. Opening the device

Take protective measures against electrostatic discharge!

Using a screwdriver, the snap lock of the upper part of the housing is unlocked on both sides. The upper part of the housing and the electronics can now be pulled out by approx. 3 cm.

4.3.4. Configuring the input current range and measuring method

(Rough setting via DIP switch)

You have the choice: True r.m.s. value or arithmetic average!

The measuring principle must be preset with DIP switch 9:

Measuring principle DIP 9
True r.m.s. value AC and DC without digit sign OFF
Arithmetic average DC with digit sign ON

True r.m.s. value:

The true r.m.s. value of an AC current corresponds by definition to the permanent value resulting from the momentary values of the current. This permanent value generates the same heat in an ohmic resistor as a DC current of the same strength. True r.m.s. value simply indicates that distorted and pulsating currents are also measured.

Arithmetic average:

The arithmetic average serves to measure DC currents or filter a DC portion from a pulsating current. Using the arithmetic average on a symmetrical AC current would result in a measured value with the value "0".

The arithmetic average makes it possible to make bipolar DC currents available as analog standard signals at the output.

4.3.6. Configuring the threshold value output

The relay and transistor output of the threshold value versions (MCR-S-...-SW-DCI) are set after the input measuring range and the analog output have been adjusted.

Setting the switching threshold:

The illustration opposite (Fig. 4) shows the four possibilities of switching behavior of the relay and transistor output. The splitting of the various operational behaviors in threshold value operation is carried out on the principle of operating current or quiescent current and after threshold value triggering when below the threshold value point or when it is exceeded.

If necessary, the corresponding switching behaviour can be set via DIP switch 7 and DIP switch 8.

Fig. 2	Operating current-controlled when lower than threshold value	ON	OFF

t_1 can be set with software and potentiometer.

Fig.4

4.3.7. Fine adjustment of the measuring transducer

After roughly setting the input current range and preselecting the output signal, the module must be closed and connected to the signal lines and operating voltage following chapter 4.1. "Electrical connection".

When the green LED lights up (operating voltage display) this shows that the operating voltage of 20...30 V DC is connected.

ATTENTION:

When using the MCR-S-1-5-...-DCI, please be sure to use the signal input terminal block to suit your measuring range!

Signal input range	Signal input terminal	Ground terminal block
1 A 7	8
5 A 6	8
10 A 5	8

Please adhere to a warm-up phase for the module of 2 minutes before the adjustment procedure.

4.3.7.1. Analog output

ZERO and SPAN behavior ( ± 25 % each) are shown in the graphic below:

• ZERO potentiometer for zero adjustment.
• SPAN potentiometer for upper range (full scale) value adjustment.

Adjustment:

graph LR
    A["Signal input"] --> B["A"]
    B --> C["MCR-S"]
    C --> D["V"]
    D --> E["U_A"]
    E --> F["A"]
    F --> G["Operating voltage"]
    G --> H["I_E"]
    H --> I["Signal output"]

Fig.7

• After the operating voltage and the signal lines have been connected, zero or offset must first be adjusted. No signal may be present at input ( I_i = 0 ).
• The analog output must correspond to a preselected output signal from table 6.3.5. Any inaccuracy can be adjusted with the ZERO potentiometer.
• To adjust the measuring upper range (full scale) value, a current of preferably the strength of the upper range value should be given. If this is not possible, one of the following adjustment equations should be used:

Example: The current transducer is to be set to the following values:

Input measuring range: 0...5 A I

$$ \mathrm{MI} = 5 \mathrm{A} $$

Output measuring range: 0...20 mA I

$$ 0 = 0 \mathrm{mA} \mid_ {\mathrm{MO}} = 2 0 \mathrm{mA} $$

Constant current for configuration I

$$ _ 1 = 3 \mathrm{A} $$

$$ \boxed { \begin{array}{c} I _ {A} = I _ {0} + (\frac {I _ {E}}{I _ {M E}} * (I _ {M A} - I _ {0})) \ U _ {A} = U _ {0} + (\frac {I _ {E}}{I _ {M E}} * (U _ {M A} - U _ {0})) \end{array} } $$

The output current calculated must be adjusted with the SPAN potentiometer to I_O = 12 mA.

When the voltage output is used, the same adjustment procedure is necessary.

4.3.7.2. Threshold value output

A current that corresponds to the threshold value is to be given for the module.

The TIME potentiometer must be set to "0 s" and the threshold value (SW) potentiometer is to be turned according to the following adjustment ruling (following Fig 4, page 22):

• Fig. 1: The threshold value (SW) potentiometer must be turned until the SW-LED lights up.
• Fig. 2: The threshold value (SW) potentiometer must be turned until the SW-LED goes off.
• Fig. 3: The threshold value (SW) potentiometer must be turned until the SW-LED goes off.
• Fig. 4: The threshold value (SW) potentiometer must be turned until the SW-LED lights up.

In order to avoid switching actions at the binary output level during a brief overload, a suppression time must be set with the TIME potentiometer. If an increased current is present for longer than the given suppression time, the preselected switching behavior becomes active. The possible adjustment range is between 0 and 20 seconds.

When the yellow threshold value (SW) LED lights up (relay and transistor status display) the N/O contact of the PDT contact is closed and the N/C contact of the PDT contact is open. The transistor output switches through.

4.4. Software package (adapter)

As an alternative to setting via DIP switch, programming is possible using MCR/PI-CONF-WIN, the configuration software (Order No. 2814799).

The software offers the following:

• Entering all the configuration parameters in the computer
• Saving the parameters entered in the computer in the measuring transducer
• Exporting the parameters available from the module
• Saving parameters in a drive of your choice
• Creating a side-panel label
• Printing the programmed module parameters
• Bar graph display
  • Monitoring function
• Input of user characteristic curves possible

The software runs under Windows 95 ^TM , 98 ^TM , ME ^TM , NT ^TM , 2000 ^TM and XP ^TM .

Interface converter MCR-TTL/RS232-E (Order No. 2814388) serves to connect the computer and the current measuring transducer. This converter has a stereo jack plug on one side for connection to the current measuring transducer and a 25-pos. SUB-D socket on the other side for connection to a computer. On the computer side, the interface converter must generally be connected with a cable adapter (25 to 9-pos. SUB-D plug connection, Order No. 2761295).

5. Sample applications

5.1. Measurement of motor currents

By using MCR-S modules in one or more input phases of the motor, so-called motor monitoring can be carried out (Fig.8).

The MCR current measuring transducer can pass on corresponding standard signals about motor load to the controller or service personnel.

The true r.m.s. measurement means that AC, DC and distorted currents can be measured. Even higher frequency currents up to 400 Hz can be measured.

5.2. Recording motor current peak loads

Large industrial motors have to be overhauled and serviced at regular intervals.

Installing an MCR current transducer in one phase of the motor feed line allows impulses to be generated with the relay or transistor switching output that can be measured with the aid of a simple meter (Fig.9). The service personnel can provide efficient maintenance on the basis of the motor starts and peak loads corresponding to the number of overloads.

5.3. Monitoring lighting

MCR current transducers can be used for monitoring lighting.

If the strength of the current in circuit is exceeded or fallen below after a suppressed turn-on time, there is a defect in the lighting circuit. If the lighting circuit fails, this signal status can be passed on to another control unit and the emergency lighting can be switched on. The same procedure can also be used with other consumers.
