1.- MAIN FEATURES

Electronics-based, Class 1 rated, electrical energy meter, with 4 lines LCD display and also with bac klight, for its use in L.V. threephase networks, These energy meters are appropriate for any application that requires the monitoring of partial energy consumptions. An additional open collector output can be used as a pulse output.

2.- Installation

This manual contains inf orm ation and warnings t hat m us t be followed for operating the ENERGY METER safely and maintaining the inst rument in a safe operating condi tion.

Whether the instrument is not used as manufacturer’s

specifications, the protection of the instrument can be damaged.

Mounting : Instrument is t o be mounted on panel (cut-out 92

+0.8

x 92

per DIN 43 700). All connections k eep i nside the cabinet.

Note that with the instrum ent powered on, the term inals , cover opening actions or elements removal may allow accessing dangerous parts. The instrum ent must not be used until this is completely instal l ed.

The monitored line should be provided with a c ircuit breaker or any equivalent element (fuses) to disconnect the instrument from the power supply network. This switching device m ust be placed near the instrument and will be easi l y ac cessible.

The supply and measuring voltage circuits will be both connected through a wire with a minimum c ros s-section of 1 m m

The line of the c urrent transformer secondary will have a mi nimum cross-section of 2,5 m m

CEP-96 has a power supply input which is independent from the measuring circuit.

Current measurement actions are done through external In / 5 A current transformers.

3.- Screen

CEP 96 has two different screens which show the imported and exported energy. By pressing the

imported energy (appears kW h on the fourth line) or the exported energy (appears -kWh on the f ourt h l i ne).

key, you can choose the

... / 5 A current inputs are isolated.

4.- SETUP

(Simultaneously press the keys MAX and MIN when working in the main program)

 The key

validates the value and passes to the next

menu.

 The key MAX permits the user to select among different

options in a menu or to increas e a digit when a variable is being entered.

 The key MIN is used to move t he cursor along the digits.

NOTE : When you arrive at t he last digit, you can move the position

of the decimal point with the "max" key. When accessing SETUP, the following message in shown in screen

for some seconds:

(1) SETUP UNLOC (SETUP unlocked ) : when the SETUP is accessed, configuration parameters can be either visualized and modified.

(2) SETUP LOC (SE TUP locked ) : when the SETUP is accessed, configurat ion parameters can be visualized but cannot be modified .

Different options are following shown in a s equent i al mode:

4.1.- Voltage Transformer Primary

On the screen we read the word "SET VOLT PRI" f ol l owed by 6 digits. They allow us setti ng t he pri mary of the voltage transformer.

PRI

4.2.- Voltage Transformer Secon d ar y

We can now set the value of the secondary of the voltage transformer. Only three digi t s are available:

001 From 1 to 999V

If the CEP-96 is directly connected t o the mains (without voltage transformer) the values of pri mary and secondary must be t he same, for instance 000001/001.

NOTE :

- The secondary of the current transformers is not programmable. It is automaticall y set at 5 A (... / 5 A ac)

- The Voltages transformer and primary current value to be set is also limited by the f ol l owing condi t i on:

- When trying to validate "

" a value exceeding the maximum allowable value, the screen will blink and the previous value will be saved.

4.4.- Setting preferred p ag e

This option allows the fixed or rotating pages ("SET def Page”):

- Fi xed page: selects Import or export screen, that will appear first when applying voltage to the CEP 96 (or on resetti ng).

- Rot at i ng pages: automatical l y rot at es the pages (every 5 seconds it moves on to the foll owing screen).

4.5.- Setting disconnection time for the backlight

Setting of the period of tim e t o go by, from t he m om ent that the CEP keyboard is not touched anymore, before the CEP’s backlight is automatically shut down (low consumption mode):

To exit this section press RESET (WARNING: in case of exit by reset, latest m odification might not be saved) or go to the SETUP2 ending.

6.- MAINTENANCE

Before any adjustment, replacement, maintenance or repairing operation is carried out, the instrum ent must be disconnect ed from any power supply source.

When any protection failure is suspected to exist, the instrument must be immediately put our of service. The instrument’s design allows a quick replacement in case of any failure. In this case contact a qualified service representative.

4.7.- Relay Output.

This output is user settable to give a pulse every certain kW.h (Energy). The value of consumed energy neces sary to generate an output pulse can be defined (duration of t he pulse is 0.1 s): kW.h / 1 pulse.

5.- SECOND SET-UP OF THE CEP-96

It is possible to access to a second MENU of SET-UP that allows the configuration of the CEP -96 with other options different of the standard ones. To enter into i t proceed as follows:

- Without power supply in the CEP-96, press simult aneously "

"max" and "min" keys.

- K eepi ng these keys pressed, supply the CEP-96. We will read on the CEP-96 sc reen t he following:

SETUP lock and unlock

- If the LOC option is sel ected, when acc essing S ETUP jus t the configuration can be check ed, but not modification is allowed.

- If the previously option is modified, a 4-digit password is requested (if it is not c orrect, then the value blinks and the previous menu is acces sed).
