-
The storage temperature must be within the range -20 °C to +80 °C.
-
If the EM-PQ 2300 has been stored for several years, especially under relatively high temperatures, it is
advisable to change its lithium battery before putting the instrument into service. See
Section 9.2 Battery,
page 35
.
10.3 Disposal
Any electronic device that is no longer required must be disposed of in an environmentally
sound manner.
CAUTION!
Incorrect disposal can cause environmental pollution.
In the European Union, electrical scrap and electronic components are subject to
the WEEE (Waste Electrical and Electronic Equipment) Directive. These
components must not be disposed of as normal domestic or commercial waste.
The backup battery fitted in the instrument must be disposed of separately for
special treatment.
See
Section 9.2 Battery, page 35
, for removal of the battery.
If these instructions are not complied with, there is a danger that environmental pollution may
result and a violation of the Directive will have occurred
In other countries, the equivalent local regulations must be followed when electronic devices
are disposed of. They must be handed in at special recycling centres.
One way of ensuring environmentally sound disposal is to return the instruments to FRAKO
Kondensatoren und Anlagenbau GmbH or the company's local representatives. Alternatively,
the instruments can be given to a firm specializing in the recycling of electronic equipment.
11. General operating notes
The following points must be observed when operating the instrument:
-
The instrument must always be operated in a closed control cabinet as described in
Section 4, Mounting
the instrument
,
page 11
.
-
All voltages applied to the instrument must never exceed the limits specified in the technical data. In the
case of S0 pulse connections, the operating parameters must be within the range called for by
DIN 43864.
-
The ambient temperatures must always be within the range specified in the technical data.
The standard radio-frequency field test as per EN 61000-4-6 (EMC immunity) calls for amplitude modulation at a
modulation frequency of 1 kHz. However, this frequency lies within the measurement range of the instrument in its
intended use (20th harmonic of 50 Hz = 1 kHz). It is therefore to be expected that the measuring circuit clearly
responds to this. For this reason, the radio-frequency field test can only be carried out without amplitude
modulation.
Instrument operation is described in
Section 8, Operation, page 29.
12. Troubleshooting
The table below offers help in troubleshooting any problems that may occur during operation of the EM-PQ 2300.
Symptoms
Possible cause
Remedy
Instrument power supply
The green
Run
LED does not
light up.
No instrument power
Check whether there is a 90
–240 V AC voltage at
the instrument power connection.
The green
Run
LED flashes
every 2.5 seconds.
Short circuit at Display
connection
Disconnect the Display connection as a test. If the
Run LED now lights up continuously, then after a
short time flashes at 1-second intervals,
investigate the cause of the overload and rectify
it.
