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 qualied staff.
The power supply plug must be disconnected and measuring systems switched off before han-
dling, 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 danger-
ous 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 haz-
ardous 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 calculat-
ed 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
THE UNIT OF MEASUREMENT”)
and there are 7 LEDs, Figure 8:

 1measurement time LED, indicating that the measurement time has not ended (in-
put mode: Frequency, Tachometer and Period.)
1RESET LED, indicating the status of the RESET input.
The unit has a three-colour LED display: red, green and orange.
The unit can automatically change the colour of the display based on the programmable pa-
rameters in the display menu (lower colour limit, upper colour limit, lower colour, middle
colour and upper colour).

Example: In a frequency measurement you can program the display to be green when the fre-
quency is below 50 Hz, orange when it is between 50 Hz and
70 Hz, and red for frequencies above 70 Hz. See section “4.7.4 Display”.

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 sufcient 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).

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 lin-
ear 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 rst 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 congured linear function.
See section “4.7.3 REGRESSION OF NON-LINEAR EQUATIONS.” for instructions on congura-
tions 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) con-
tact.
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) con-
tact.

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):
 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.
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.
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.
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.
h-on: This option is always enabled for manual simulation.
h-off: This option is always disabled for manual simulation.
