In normal operation the user is presented with one of the measurement reading

screens out of several screens. These screens may be scrolled through one ata

time in incremental order by pressing the “ Up key” and in decremental order

by pressing “ Down key”.

3. Programming

The following sections comprise step by step procedures for configuring the

Ziegler mfm 3420 for individual user requirements.

To access the set-up screens press and hold the“

Key simultaneously for 5 seconds. This will take the User into the Password

Protection Entry Stage (Section 3.1).

3.1. Password Protection

Password protection can be enabled to prevent unauthorised access to set-up

screens, by default password protection is not enabled.

Password protection is enabled by selecting a four digit number other than 0000,

setting a password of 0000 disables the password protection.

1. Introduction

The is a panel mounted 96 x 96mm DIN Quadratic DigitalZiegler mfm 3420

metering system for the measurement & display of basic electrical parameters like

AC Voltage, AC Current, Frequency, Import energy and Export energy.

The instrument integrates accurate measurement technology (All

Voltage & Current measurements are True RMS upto 15th Harmonic) with 3 line4

digits Ultra high brightness LED display.

Ziegler mfm 3420 can be configured and

programmed at site for the following : PT

Primary, CT Primary, CT Secondary (5A or

1A)

The front panel has two push buttons through

which the user may scroll through the

available measurement readings, reset the

Pressing the “ Down” key will scroll the value of

the most significant digit from 0 through to 9 unless

the presently displayed Potential Transformer Primary

Value together with the Current Transformer Primary

Value, previously set, would result in a maximum power

of greater than 120 MVA in which case the digit range

will be restricted.

Pressing the “ Up” key accepts the present value

Up less significant digit.

(* Denotes that decimal point will be flashing).

Note: the flashing decimal point indicates the cursor position,a steady decimal point will be present

to identify the scaling of the number until the cursor position coincides with the steady decimal point

position. At this stage the decimal point will flash.

When the least significant digit has been set pressing the “ Up” key will advance to the

5.1 EMC Installation Requirements

This product has been designed to meet the certification of the EU directives

when installed to a good code of practice for EMC in industrial environments,

e.g.

1. Screened output and low signal input leads or have provision for fitting

RF suppression components, such as ferrite absorbers, line filters etc., in

the event that RF fields cause problems.

Note: It is good practice to install sensitive electronic instruments that are

performing critical functions, in EMC enclosures that protect against electrical

interference which could cause a disturbance in function.

2. Avoid routing leads alongside cables and products that are, or could be,a

source of interference.

3. To protect the product against permanent damage, surge transients must

be limited to 2kV pk. It is good EMC practice to suppress differential

surges to 2kV at the source. The unit has been designed to automatically

recover in the event of a high level of transients. In extreme

circumstances it may be necessary to temporarily disconnect the

auxiliary supply for a period of greater than 5 seconds to restore correct

operation.

4. ESD precautions must be taken at all times when handling this product.

The Current inputs of these products are designed for connection in to

systems via Current Transformers only, where one side is grounded.

5. Installation

Mounting is by four side clamps, slide the side clamps through side slot till side clamp

gets fir mly locked in a groove (Refer fig.) Consideratio n should be given to the space

required behind the instrument to allow for bends in the connection cables.

As the front of the enclosure conforms to IP54 it is protected from water spray

from all directions, additional protection to the panel may be obtained by the

use of an optional panel gasket. The terminals at the rear of the product

should be protected from liquids.

The should be mounted in a reasonably stable ambientZiegler mfm 3420

temperature and where the operating temperature is within the range

-10 to 55 C . Vibration should be kept to a minimum and the product should

not be mounted where it will be subjected to excessive direct sunlight.

SLIDE IN THIS DIRECTION AND LOCK

PANEL

Ziegler mfm 3420

4. Pulse output option

The pulse output gives pulses at the rate proportional to the measured active energy kWh.

There are two options available,

1) One Pulse Output: Relay 1 can be configured either to Import Active energy or

Export Active energy.

The pulse divisor and pulse width (duration) can be configured. When two pulse outputs

are fitted,they share a common divisor value and pulse width

) Two Pulse Output: Here it is possible to assign Import Active energy either to Relay1

or Relay 2. Then accordingly Export Active energy is configured

automatically to the corresponding relay.

NOTE:

If system power is selected in W then default pulse rate is 1 pulse per Wh (upto 3600W).

If the system power is scaled in kW then default pulse rate is 1 pulse per kWh

(upto 3600 kW). If the system power is over 3600 kWh then pulse rate is 1 pulse per MWh.

5.4 Auxiliary Supply

Ziegler mfm 3420 should ideally be powered from a dedicated supply, however

it may be powered from the signal source, provided the source remains within

the limits of the chosen auxiliary voltage.

5.5 Fusing

It is recommended that all voltage lines are fitted with1 amp HRC fuses.

5.6 Earth/Ground Connections

For safety reasons, CT secondary connections should be grounded in

accordance with local regulations.

5.3 Wiring

Input connections are made directly to screw-type terminals with indirect

wire pressure. Numbering is clearly marked in the plastic moulding. Choice of

cable should meet local regulations. Terminal for both Current and Voltage

inputs will accept upto 3mm x 2 diameter cables.

Note : It is recommended to use wire with lug for

connection with meter.
