PHOTASGARD® FSHKM
Maintenance-free light intensity sensor PHOTASGARD® FSHKM with active output,
in in-wall housing, to determine the illuminance (0…1kLux). The measuring
transducer converts the measured variables into a standard signal of 0 -10 V.
The in-wall sensor is mounted in high-quality panel switch programmed, ideally
of the brands Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (using in-
wall adapters) either individually or in combination with light switches,
socket outlets, etc.
The sensor is used to control luminaires, lighting systems, Venetian blinds
and canvas blinds and for monitoring the lighting conditions.
It is used indoors at workplaces, in corridors, offices, residential and
business premises as well as industrial and storage halls as daylight-
dependent constant light control, as brightness or twilight sensor and to
control sun protection hoods to avoid unnecessary room heating.
The light sensor (photodiode) was specifically adapted to the sensitivity of the human eye. It is most sensitive in the range of 350 nm to 820 nm. With its special filter, the sensor is therefore ideally suited to exposure measurement of daylight and ⁄ or for measuring artificial light of high color temperature (similar to sunlight).

SUPPLY VOLTAGE :
For operating voltage reverse polarity protection, a one-way rectifier or
reverse polarity protection diode is integrated in this device variant. This
internal one-way rectifier also allows operating 0 – 10 V devices on AC supply
voltage.
The output signal is to be tapped by a measuring instrument. Output voltage is
measured her against zero potential (O V) of the input voltage!
When this device is operated on DC supply voltage, the operating voltage input
UB+ is to be used for 15…36 V DC supply and UB – or GND for ground wire!
When several devices are supplied by one 24 V AC voltage supply, it is to be
ensured that all ”positive“ operating voltage input terminals (+) of the field
devices are connected with each other and all ”negative“ operating voltage
input terminals (–) (= reference potential) are connected together (in-phase
connection of field devices). All outputs of field devices must be referenced
to the same potential!
In case of reversed polarity at one field device, a supply voltage short-
circuit would be caused by that device. The consequential short-circuit
current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!
Photodiode 
The sensor used in PHOTASGARD® light intensity sensors (photodiode) was specifically adapted to the sensitivity of the human eye. Its greatest sensitivity is in the range of 350 nm to 820 nm. Therefore with its special filter the sensor is predestined for exposure measurement of daylight and ⁄ or for measuring artificial light of high color temperature (similar to sunlight).
General notes
-
The sensor is installed in the enclosure cover of the housing.
When opening the housing, make sure that the sensor does not get damaged. -
The sensor surface must be protected from any dirt and ⁄ or damage.
-
Scratches, dirt or even partial obstruction distort the measurement result.
-
When several sensors are connected to one voltage supply of 24 V AC (alternating voltage), the correct polarity must be ensured as otherwise the alternating voltage source may be short-circuited.
-
The outputs are short-circuit proof; applying overvoltage or voltage supply to the output will destroy the unit.
-
If this unit is operated beyond the specified range, all warranty claims are forfeited.
Notes regarding mechanical mounting and attachment:
Mounting shall take place while observing all relevant regulations and
standards applicable for the place of measurement (e.g. such as welding
instructions, etc.). Particularly the following shall be regarded:
- VDE ⁄ VDI directive technical temperature measurements, measurement set – up for temperature measurements.
- The EMC directives must be adhered to.
- It is imperative to avoid parallel laying of current-carrying lines.
- We recommend to use shielded cables with the shielding being attached at one side to the DDC ⁄ PLC.
Before mounting, make sure that the measuring device technical parameters comply with the actual conditions at the place of utilization, in particular in respect of:
- Measuring range
- Permissible maximum temperature and humidity
- Protection type and Protection class
- Oscillations, vibrations, shocks are to be avoided (< 0.5 g)
