Installation and users manual

Please read this before installation
This manual is intended for skilled personal having a formal knowledge to meters.
The Brunata HGP-SIV energy meter must only be used and installed as described in the
manual.
The working data of the meter are shown on the label of the meter. For further information
we refer to the data sheet.
IMPORTANT: Seals and void labels must not be removed or damaged. This will infringe
the warranty of the meter.
The meter contains of following parts:
1. Flow sensor
2. Flow electronic unit
3. Display unit
4. Signal cable between flow electronics and display unit
5. Two paired temperature sensors with sensor pockets
6. Installation and users manual
When unpacking the meter, please check that all parts are enclosed. The serial numbers
of the flow sensor, the electronic units, and the temperature sensors must be identical,
since the parts are calibrated. The serial number is also programmed into the memory

Installation
Preparation for installation
Please note that the installation must be done in such a way that it meets the requirements
for internal fitting, distances that have to be respected, etc. Straight pipe sections
before or after the meter are not required.
It is recommended that stop valves are fitted before and after the meter to
make it easier to remove and reinstall the meter if service and verification are
required. To ensure that there are no foreign bodies in the pipe section, it is recommended
that the pipes are flushed through before the meter is installed. A
adapter pipe can be used for this purpose. After installation, the valves should
be opened in the order which provides correct flow through the meter.
The HG-meter has been approved for installation in industrial areas, but it is recommended
that installation close to components that may cause strong electromagnetic
interference is avoided.
Installation of the flow sensor
The flowsensor is installed with the arrow in the flow direction. The flow sensor can
be installed in any direction (vertically, horizontally etc), only the flow sensor must always
be filled with water when running. Do not insulate the housing of the flow sensor.
The meter’s type label will indicate whether the flow sensor should be fitted on the return
pipe (low temperature) or the supply pipe (high temperature). Please note that if the meter
is used in a cooling system, the supply pipe is low temperature.
Fitting and connection of flow electronic unit, fig. 1
Place the flow electronic unit on an even surface with 3 screws. All connections to the
meter must be fitted before mains voltage is connected.
The connection cable from the Flow Sensor is inserted into the socket marked Flow
Head [8] in fig. 1. Note the locking system and how the cable exits the box. To dismantle
the plug, use a small screwdriver to lift the lock. Never shorten nor lengthen the cables
for the flowsensor. If the cable must be rolled up, the diameter of the roll should
at least be 30 cm.
The power supply cable (230 or 24 V) is inserted through the strain relief, which must
be tightened before tightening the terminal connections [1] in fig. 1.
Signal cable to display unit are installed in terminals A1, A2, B1 and B2, [11] in fig. 1.

Fitting and connection of display unit, fig 2
Place the display unit on an even surface with 3 screws. All connections to the meter
must be fitted before mains voltage is connected.
The connecting cable from flow electronic unit is connected to plug M57, see fig 4.
The other cables that need to be connected are led through rubber membrane and
bypass and connected with their respective terminals. Temperature sensors are connected
with terminal [2] and [3], pulse inputs with terminal [9] and [10], and the remote
reading with terminal [5] and [6]. A small screwdriver or the like can be used to perforate
the rubber membrane.
The power supply cable for 230 Volt (possibly 24 Volt) is led through the rubber
membrane and connected with terminal [4] in fig.1, then the strain relief is tightened
moderately. Earth connection is not required.

Putting the meter into operation
Mains voltage is connected to both units and the meters starts registration at once. The
meter does not sustain damage if there is no water in the system, but it may register a
random flow in case the flow sensor is not completely filled with water.
In the upper right corner of the PCB are two lightemitting diodes (LEDs) for indication
of signals. The green LED indicates received flow signal from HGP an when you have
flow the LED flashes. If it does not flash it could be due to lack of flow, the connector
has fallen out or has been reversed.
The red LED indicates that data is being sent to the calculation unit. It flashes every 1.6
seconds and if it does not flash it is advised to check if the connector M57 is installed
correctly and that the connections A1, A2, B1 and B2 are working correctly. See table
and drawings.
When the meter is connected and water is running through the flow sensor a square in
the display is flashing concurrently with the water pulses.
Attention: The meter’s counter cannot be zeroed after delivery.

Operating the meter
Introduction
The meter is operated using the push button on the
front of the electronic unit. Pressing once you step
down in the actual menu you are in. By pressing
the button in a few seconds, you can step from one
menu to the next.
Except for the User Menu the No. of the actual
menu is shown in the display.
Push
button
In case the meter is delivered with Storage Menu, the meter read itself and stores data
as default on the 1st each month or at an optional selected date, see the order confirmation
or consult the Service Menu. Until the first date occur the menu will be empty,
displaying _ _._ _._ _._ _
Peak values are registered in the period from the 1st in actual month. Values are reset
(zeroed) at each turn of the storing date e.g. for standard meters each month.
In addition to registration of the highest return temperature (Peak t L
) the concurrent
flow temperature (Peak t H
) is registered.
With meters supplied with module for remote reading, the user himself in the User
Menu can check the time where the meter has been read. The communication address
of the meter appears in the Service Menu.
Normal operation – User menu
By pushing the button once there will be light in the display, and you will see the accumulated
energy (MWh). When pushing once again the display will change to different
pictures (see above). After the last display picture in the menu the display will show the
accumulated energy (MWh) again.
When the pushbutton has not been activated for approx. 1 minute the display will automatically
return to accumulated volume (MWh) and the light will turn off.
Advanced operation – all menus
When holding down the button for a short while, the display will change from one
menu to the next. The menu reached is indicated in the upper part of the display (except
Menu 1). The order of the menus is therefore [none], 2, 3, 4.
When you reach the needed menu, release the pushbutton and the menu is now activated.
By pushing once the different display pictures in the chosen menu will show (as
mentioned above).
Display pictures containing peak values - f.inst. peak flow, peak power etc., will automatically
alternate between peak value and date/time of registration.
12

For meters delivered with tariff function the consumption is displayed in Tariff Energy
$ and Tariff volume $, according to the criteria’s selected. The selected criteria can be
seen in the service menu.
Stored data menu
If the meter is programmed for storage of data, in menu 3 you find data stored for 24
accounting periods, and you can step through the different periods by pressing the button
quickly twice. The date and time when the data has been stored is shown as first
display in each accounting period. The first period showed are the most recent. You
can step through the information stored by pressing the button once. By pressing the
button quickly twice you step to the next period, and after having reached the latest
reading (register 24) you will again see the most recent readings.
Information and error codes
Should an error occur in the meter, the display will be flashing ”Error” followed by one
of following error codes:
1. Interruption of power supply. The information is logged in the error register, and not
showed in the display.
2. No registration of flow pulses within the last 24 hours, provided that the temperature
difference has exceeded 20 °C.
3. Error, temperature sensor T H
, warmest pipe [-30 °C > T H
> 200 °C].
4. Error, temperature sensor T L
, coldest pipe [-30 °C > T L
> 200 °C].
5. Low voltage in back-up battery [V Bat
< V Treshold
].
6. Short circuit of magnet coil in the flowsensor [Coil current exceeds limit value for
more than 8 sec].
7. Error in the programming of the meter [RAM not initialised].
8. The temperature sensors in flow pipe and return pipe are reversed [Negative temperature
difference exceeds limit value for more than 10 sec].
9. Wrong time/date in the meter (see Service Menu) – clock must be adjusted.
In case of error the meter automatically will registers when (date and time) the error has
occurred and also the accumulated error time.
When two errors occur at the same time, both codes are shown. Example: Error code
36 indicates problems with the temperature sensor in the warmest pipe and with the
flow sensor.
At code nos. 2, 3, 4, 6 and 8 the error message is shown in the display as long as the
error occurs. The hours with error are registered in the register for Accumulated error
13

hours. If the power supply is terminated, the time without power is registered in the
error hours register.
At code 5, 7 and 9 the error message is shown in the display as long as the error occurs,
but will not be registered in the register for Accumulated error hours.
By interruption of the power supply the display will be blank. When the power is reestablished
the meter will immediately start registering again.
By error code 5, low battery-supply, the meter will continue the normal registration as
long as it is powered but the battery must be replaced as soon as possible.
By error code 9, the meter has been without power supply, and battery-supply. The
meter will continue the normal registration when power is restored, but the internal
clock should be adjusted.
At temperature difference below 0.1 K, the energy calculation will seize. The register
“Accumulated flow sensor volume” will continue registering the flow.
The meter’s operating hours counter starts registration as soon as the meter is connected
to the mains.
In case of questions, you are always welcome to contact your local Brunata service
department, or send an e-mail to service@brunata.dk.
