3.3 Output of loop frequency
Approx. 1 sec. after calibration of the detector the loop frequency will be
displayed by pulse signals of the green LED. Firstly the 10 kHz position
of the frequency value will be indicated. For every 10 kHz frequency
value the green LED flashes once. After a break of 1 sec the 1 kHz
position is displayed in the same manner. If there is value of '0' in the 1
kHz position there will be displayed 10 flashes. The flashes for 1 kHz
position are a little bit shorter than for the 10 kHz position.
Example for 57 kHz loop frequency:

Safety information and warnings
The device should only used for the applications described by the
manufacturer.
Please keep this operation instruction always accessible and hand
it over to every user.
Inadmissible modifications to the device, use of repair parts and
supplementary equipment which are not sold or recommended by
the manufacturer can cause burning, electric shock and injuries.
Therefore the manufacturer has no liability and this excludes all
demands of warranty.
The warranty regulations of the manufacturer are valid in the
version of the purchase date for that device. There is no liability for
not suitable, wrong manual or automatic adjustments also regard-
ing no suitable applications of the device.
Repairs may only made by the manufacturer.
The power supply must be fulfill the requirements for SELV and
limited power sources according to EN 60950-1.
All connections, the start-up, maintenance, measurements and
adjustment operations to the detector have to be made from elec-
trical specialists who have special know-how in the prevention of
accidents.
For the use of devices which have contact to electrical power,
please pay attention to the valid security instructions and all pre-
vention orders of fire and accidents.
The user is responsible for an installation, which has conformity to
all technical rules in the country where the device is mounted, and
also to all regional valid orders. For that the dimension of cabling,
fuse protection, connection to ground, switch off, disconnection,
isolation controlling and the protection for overload current have to
be regarded in detail.
The detector can not be used as a security device regarding to the
security instructions of electrical machines. Using in systems with
high danger potential it is necessary to include additional protection
devices!
All work on the device must be carried out in accordance with the
national electrical codes and regional regulations.
