In the industry, a higher power

consumption than the contracted one can

lead to severe penalties. Often there are

power peaks produced by loads

coincidence that normally do not work in a

simultaneously. In order to avoid

penalties, one solution would be

increasing the contracted power

according to the maximum registered

peak, but on contrast this will force to pay

a higher power than it is really needed.

Another solution will be avoiding the

consumption peaks through a vigilance

element that advise us of the risk situation

or it can disconnect certain dispensable

loads ( air conditioning, compressors,

lighting...)

The new has been

designed especially for the control of

power demand through energy pulses. By

means of this equipment, the consumed

power during an integration period can be

controlled, depending on the energy

pulses that arrive to the energy meter

from the utility.

To achieve this the has

up to 4 relays to connect and disconnect

the required loads in the most optimum

way or activating an alarm that informs

us about this situation.

The equipment calculates the energy

demand, peak, its medium value, and

consumed. The peak and medium

demand values as well as consumed

are saved in a non-volatile , avoiding

this way its lost when the auxiliary supply

drops

The instrument has 4 digits

and 8 indication red colour leds. The

equipment parameters are configurable

by means of 4 frontal keys.

DH96-CPP

The has been designed to

offer a wide range of features and

performance qualities in a compact and at

the same time robust equipment that

allows to work in industrial atmospheres

under all requirements of applicable

standards.

Instruments of Series have been

tested in laboratories, checked in

industrial environments, and have

successfully passed the most rigorous

tests involving ambient conditions,

electrical noises, electromagnetic

disturbances, mechanical vibrations,

etc...

The instrument has an additional

communications card that

whenever it is required can be

incorporated in the device.

Through this card and by means of

protocol, mode, we will be

able to:

Check the relays state, connect and

disconnect them whenever is needed.

Read all measuring parameters:

demand, totalizers, peak and medium

values, and reset them.

Visualize and modify the programming

parameters.

MODBUS communications protocol.

Instrument address selection.

Communication speed selection 1200,

4800, 9600 and 19200 bits/s.

Parity selection: even, odd or without.

Stop bits selection: 1 or 2.

Installation

¡Warning!

The DH96 meets protection class I:

It is provided with earth terminal.

The case is not dangerous to tactile

touching (isolation material)

Screws of terminals are not

accessible for human appendix.

This instrument has been designed

and tested to meet IEC348 standard and

is supplied in proper conditions. This

manual contains information and

warnings that the user should respect in

order to guarantee a proper operation of

all instrument's functions and keep its

safety conditions.

The instrument is for indoor use. It

could be occasionally subjected to

temperatures between -10 ºC and +75 ºC

keeping its safety conditions.

The instrument must not be powered

and used until being correctly assembled

on the board.

Before powering the instrument, its

earth terminal must be connected to a

suitable protection cable.

Any interruption of the protection

conductor, either inside or outside the

instrument, or the disconnection of the

protection earth terminal might imply a

dangerous situation; therefore, any

intentional interruption is wholly

forbidden.

;

Adjustment, spare parts and

repairing actions.

Defects and malfunction

With the instrument powered on, the

terminals could be dangerous to touch and

cover opening actions, may allow

accessing dangerous parts. Therefore,

before any adjustment, replacement,

maintenance or repairing operation is

carried out, the instrument must be

switched off from any power supply source

No adjustment, maintenance or

repairing operation should be done over

the instrument opened and powered, and

if they are essential, high-qualified

operators must perfom them.

Check that fuses used for replacing

damaged ones match required types and

rated currents. Unsuitable fuses or short-

circuit fuse bases must be completely

forbidden.

When any protection failure is

supposed to exist, the instrument must be

put out of service. The protection can be

damage whether:

You can see visible damages.

It cannot perform proper

measurements.

Storage conditions were not the

suitable ones.

Any damage in transport happened.

WARNING

Proceed as pictures show below:

: Insure that no incoming

wire is connected to the equipment before

doing any manipulation work on the

equipment, since observed failure in the

equipment can provoke equipment

damages and even serious injury.

1) Press the case holding piece with a

screwdriver or a similar tool in order to

release the base from the rest of the case.

2) Remove the set composed by the

base and circuits by pulling the base and

carefully sliding it out.

3) Insert the card into the suitable

connector. Take care that only the

connector is pressed but not all the card.

4) Put the set composed by the base

and circuits in, again, by pushing the base

and carefully sliding it inside. When the set

is totally inserted, press until the case

holding pieces are fitted into the pertinent

holes.
