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.

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.
