Operating instructions Safety instructions
Observe the notes on mains supply. No other
form of mains supply other than specified in
these instructions may be used.
Conventional batteries must never be charged.
Danger of explosion!
Do not throw batteries into fire! Do not short-
circuit batteries!
Only operate device indoors and avoid influence
of humidity, dust, sunlight and heat.
Proper use
The LED sensor is used to collect current con-
sumption data at an electronic household meter.
Uses other than those specified in these operat-
ing instructions are not in accordance with the
intended purpose and lead to exclusion of war-
ranty and liability. This is also the case with mod-
ifications and conversions.
The values measured are not suitable for
purposes of public information. The device
is intended solely for private use and not for
invoicing.
The main meter is usually sealed and is the
property of the utility company. Modifications
are prohibited. If measurement devices are
installed, these must not influence the meter and
must be completely removable. The LED sensor
is designed to fulfil these requirements. No
modifications to the meter or mains supply
are required due to contactless, optoelectronic
determination of measurement data.
Functional description
The Gira LED sensor consists of a sensor unit
and a transmitting unit. The sensor unit registers
the flashing of the pulse LED of the electronic
household meter and passes the measurement
data on to the transmitting unit. This transmits
the data to the Gira energy and weather display.
The transmitting unit features an LED which illu-
minates when there is radio transmission. In nor-
mal operation, after pressing a button the dis-
play of the transmitting unit shows the average
power between the last two pulses for a period
of three minutes.
The sensor unit and transmitting unit are located
in separate housings for ideal positioning. In this
way the sensor unit can be positioned directly at
the electricity meter and the transmitting unit
can be positioned at a location with good radio
reception with the aid of a connection cable.
Sensor unit Transmitting unit
Inserting/replacing batteries
The sensor unit is supplied with voltage via the
transmitting unit. This is operated with four
alkaline batteries (1.5 V, type LR6, Mignon, AA).
Both sides of the transmitting unit have small
indentations to open the battery compartment.
1. Insert a screwdriver into the indentations and
pull off the battery compartment cover.
2. Insert four LR6 batteries with correct
polarisation into the transmitting unit.
3. Replace the battery compartment cover and
snap it in.
Side view Battery compartment
“Empty battery” display
If the batteries are empty, bAt appears in the
display of the transmitting unit (alternating with
the normal display).
If this is the case, replace the station's batteries.
The assignment to the energy and weather
display is maintained when replacing the battery.
Assigning the transmitter
Radio components must be assigned to each
other to enable communication.
1. Press and hold on the transmitting unit for
3 seconds.
✓The transmitting unit now transmits an assign-
ment signal every five seconds for the next
five minutes. The LED of the transmitting unit
lights up for the duration of this assignment
process.
2. Trigger the programming mode on the energy
and weather display within these five minutes
(see operating instructions for the energy and
weather display).
✓After start-up the transmitting unit displays its
version number as well as „kW“ for 1 second.
This signalises that the sensor has been
assigned.
✓Following successful assignment the energy
and weather display then shows the electricity
meter data.
3. Pressing again exits the programming
mode of the sensor.
A sensor can be assigned to any number of
energy and weather displays.
Deleting the assignment
Deleting the LED sensor assignment is only
possible on the energy and weather display.

Using batteries
The LED sensor may only be operated with
alkaline batteries. Rechargeable batteries
must not be used.

Mounting
Mounting the sensor unit
Use the included template to mount the sensor
unit.
1. Clean or degrease the front panel with a
suitable cleaning agent.
2. Place the template onto the front panel of the
meter so that the LED of the meter is centred
the positioning opening of the template.
3. In this position, trace the marking points of
the four marking holes using a suitable pen.
4. Remove the protective film from the sensor
unit.
5. Affix the sensor unit to the front panel of the
meter. While doing so, position the sensor
unit within the four traced markings.
Mounting the transmitting unit
1. Connect the transmitting unit to the sensor
unit with the connection cable.
2. Check whether the energy and weather
display is receiving data regularly from the
transmitting unit. If necessary, modify the
position of the transmitting unit or energy
and weather display to establish good radio
communication.
For wall mounting, use the two keyholes on the
rear.
1. Mark the drilling holes.
2. Drill the mounting holes (Ø 5 mm) and insert
the included dowels.
3. Fasten the included screws. These must
protrude by approx. 0.5 cm to hang the
transmitting unit.
Setting the meter constant
For correct measurements, the meter constant
specified on the meter must be set. The meter
constant specifies how many pulses the meter
LED makes for energy consumption of 1 kWh.
The meter constant is usually printed on the
meter. If not, the value can be obtained from
your utility company.
1. Press and hold Mode for more than
2seconds.
✓The display shows the
currently set meter
constant in pulses/kWh
and the LED of the
transmitting unit lights up.
2. Set the required meter constant with and .
Counting up and down is accelerated if the
buttons are pressed and held longer than
2seconds.
3. Press Mode to save the value and return to
normal operation.
✓If no button is pressed for longer than
60 seconds the device automatically returns
to normal operation. The set meter constant is
saved in this case.
✓The LED of the transmitting unit displays each
transmission by intermittently lighting up until
10 minutes after the last button press at the
transmitting unit.
✓For the next 3 minutes, current consumption
between the last two pulses is displayed in W.
No signalling is output after this to protect the
service life of the batteries.
To activate triggering of the LEDs for 10 minutes,
briefly press any button of the transmitting unit.
Transmission behaviour and radio
interference
The transmitting unit transmits data at periods of
2 - 3 minutes to the energy and weather display.
Radio transmission occurs on a non-exclusive
transmission path, and interference cannot be
excluded for this reason. For further information
please consult the energy and weather display
operating instructions.
In order to manually restore synchronisation, the
assignment of the transmitting unit to the energy
and weather display can be deleted and
reassigned, as specified in the “Assigning the
transmitter” section.
Maintenance and cleaning
The product is maintenance-free apart from
battery replacement. Leave repairs to a qualified
expert.
Clean the product with a clean, soft, dry and
lint-free cloth.
The cloth may be dampened slightly with
lukewarm water for removal of heavier soiling.
Do not use solvent-based cleaning agents. The
plastic housing and inscription may be adversely
affected.
Disposal information
Remove empty batteries immedi-
ately and dispose of them in an
environmentally-friendly way.
Do not dispose of batteries with
household waste. Local authorities
provide information about environ-
mentally-sound disposal. The end
consumer is legally required to
return used batteries in accordance
with legislative requirements.

Work precisely!
The sensor unit must be positioned exactly
above the pulse LED. Incorrect positioning by
just a few millimetres may cause malfunction-
ing. This is why the following work steps must
be carried out very precisely.
