3.- Unit installation
3.1.- PRELIMINARY RECOMMENDATIONS
In order to use the unit safely, it is critical that individuals who handle it follow
the safety measures set out in the standards of the country where it is being
used, use the personal protective equipment necessary, and pay attention to the
various warnings indicated in this instruction manual.
The DHB-1xx unit must be installed by authorised and qualified staff.
The power supply plug must be disconnected and measuring systems switched off before handling, altering the connections or replacing the unit. It is dangerous to handle the unit while it is
powered.
Also, it is critical to keep the cables in perfect condition to avoid accidents, personal injury and
damage to installations.
The manufacturer of the unit is not responsible for any damage resulting from failure by the
user or installer to heed the warnings and/or recommendations set out in this manual, nor for
damage resulting from the use of products or accessories that did not come with the unit or that
were made by other manufacturers.
If an anomaly or malfunction is detected in the unit, do not install the unit nor use it to take any
measurements.
Inspect the work area before taking any measurements. Do not take measurements in dangerous areas or where there is a risk of explosion.
Disconnect the unit from the power supply (unit and measuring system power
supply) before maintaining, repairing or handling the unit's connections.
Please contact the after-sales service if you suspect that there is an operational
fault in the unit.

3.2.- INSTALLATION
The unit is installed on a panel. The thickness should not exceed 6 mm. Drill panel at 92+0.6 x
45+0.6 mm.
Terminals, opening roofs or removing elements can expose parts that are hazardous to the touch while the unit is powered. Do not use the unit until it is fully
installed.
All the connections are located inside the electric panel. The unit must be installed on the panel
from the front. Attach the unit with the 4 brackets to support the panel (Figure 1)
Cross-section of the cable for the measurement inputs: 1.5 mm2.
Cross-section of the cable for the remaining connections: 2.5 mm2.
The unit must be connected to a power circuit protected by a circuit breaker switch or equivalent
device located close to unit, marked accordingly, and easily accessed by the operator.

Measurement data area, for viewing the value of the parameter measured or calculated by the unit.
 Unit of measurement area, where you can see the unit for the parameter you are
viewing. To do so, select the label with the unit of measurement you wish to use and stick
it in its space. Then activate the corresponding LED (see section “4.7.10.4. DISPLAYING

4.4.- REGRESSION OF NON-LINEAR EQUATIONS
Normally, an instrument's measurement is given by the equation for a line; in other words, there
are two pairs of points that provide the measurement.
However, it may be the case that two points are not sufficient to adjust the signal's operation.
For this reason, the DHB-1xx can work with non-linear equations with up to a maximum of 20
points (Figure 9).

Input function
Linearised function
Figure 9:Regression of non-linear equations.
Once the number of points with which the function will be linearised has been selected (the
number of functions is one fewer than the number of points), program the consecutive points
by giving them the measured values (Xi) and the values expected to correspond to them (Yi)
(0 < i < n).
While the function is being estimated, keep in mind that with non-linear functions, the more linear segments there are, the less error there will be in terms of the linearisation.
If the measured values are less than X1, then it will rescale, based on the first line calculated at
points (X1, Y1) and (X2, Y2).
Values above Xn (where n < 22- the last measured value), will display a calculated value based
on the last configured linear function.
See section “4.7.3 REGRESSION OF NON-LINEAR EQUATIONS.” for instructions on configurations for non-linear equation regressions.

4.5.- ALARMS
The DHB-102 unit has:
1 alarm relay, Alarm 1, terminals 13 and 14 of Table 2, with normally open (NO) contact.
3 alarms, Alarm 2, 3 and 4, fully programmable but not linked to any relay.
The DHB-124 model has:
1 alarm relay, Alarm 1, terminals 13 and 14 of Table 3, with normally open (NO) contact.
 2 switched alarm relays, Alarm 3 and 4, terminals 31, 32, 33, 34, 35, and 36 of Table
3.
1 alarm, Alarm 2, fully programmable but not linked to any relay.
Each of the alarms can operate in the following work modes (Figure 10):
ü n-on: the alarm is activated when the average value exceeds the upper value PrH and
does not deactivate until it is below the lower value PrL.
ü n-off: the alarm is deactivated when the average value exceeds the upper value PrH
and does not activate until it is below the lower value PrL.
ü on: the alarm is activated when the average value exceeds the lower value PrL and
does not deactivate until it is above the upper value PrH.
ü off: the alarm is deactivated when the average value exceeds the lower value PrL
and does not activate until it is above the upper value PrH.
ü h-on: This option is always enabled for manual simulation.
ü h-off: This option is always disabled for manual simulation.

4.8.- CONFIGURATION EXAMPLES.
Below are three examples of possible programming options.
Example 1 :
Programming the unit to work with a flow meter with a relay output with the following parameters:
Impulse constant: 1K - 4.3956 dm3/impulse = 0.0043956 m3/impulse.
Minimum flow (Qmin): 0.02 m3/h .
The main input should be programmed as follows:
 tYP1 the input type is configured as a frequency for f<10 kHz : FreqL.
 The impulse constant must be in m3, but only to 5 significant digits.
If the multiplication conversion method is selected, the value of 0.0044 should be programmed
in the conversion constant parameter (entering a margin of error of 0.1% in the result).
To reduce the margin of error, select division as the conversion method. The conversion
constant in this case is:
.
.
.
The margin of error is reduced to 0.0001%.
Configure SCAL1 as dIv and Cons1 as 227.50.
Configure the minimum duration for low impulse level at the input, t_L1, and the minimum
duration of high impulse level at the input, t_H1, as 10 ms.
Disable the external inputs, E_In1 configured as but.
In Auto1 set the maximum time expected between impulses: 16 s.
FUnCt should be set at oFF as there no mathematical functions.
Cnt1 set to 1 (the average current measurement each second).
Configure non-linear equations as:
→ IndCp set to 2 points.
→ X1 set to 0 (Hz), Y1 set to the flow corresponding to 0 m3/h.
→ X2 set to 1 , Y2 set to the flow corresponding to 3600 m3/h.

Instruction Manual
DHB-102 DHB-124
Example 2 :
Programming the analogue output.
If we wish to configure a 4...20 mA output proportional to the flow, 4 mA - 0 m3/h, 20 mA - 125
m3/h, the configurations would be:
 P_An The analogue output will be applied to the main meter, W1 : Inp1
 After configuring the analogue output type as 4...20mA, configure the display value you wish
to have at the beginning of the analogue output: AnL= 0
 Configure the display value you wish to have at the end of the analogue output: AnH=125
Example 3 :
Programming alarm relay 1.
If we want alarm 1 to be activated in a flow range of between 1 m3/h and 30 m3/h with a delay
of 10 seconds, the configurations would be:
 P_An1 The alarm relay will be applied to the main meter: Inp1
 PrL1 Configure the alarm low value as 1.
 PrH1 Configure the alarm high value as 30.
 typ1 Configure the alarm type as on.
 dLy1 Set the connection delay at 10 s.
 LED 1: Configure as needed:
On LED interlocked / Off LED not interlocked.
