19 Maintenance, recalibration, disposal

19.1

Maintenance and recalibration

The following components need regular maintenance:
The backup battery in the CPU module must be replaced in the factory after 10 years.
The contacts of the electromechanical relay in the output module 2 x 240 VAC must, depending on the load, be checked
after 5-10 years and, if necessary, replaced.
Furthermore, periodic recalibration is prescribed by national calibration regulations for devices in
commercial use.
Devices in commercial use
Maintenance Calibration period as per national regula-
interval tions. For energy calculators, normally 5
years
Tasks Recalibration
Functionality test, replacement of obsolete components
After 10 years, replacement of the internal battery in the CPU module (soldered button cell)
*. If desired, the counter readings can be reset to zero during recalibration. This must be taken into account
when calculating bills.
19.2

Dispatch

The modules to be recalibrated can be sent to the supplier, i.e.:
3. The CPU module
4. All input modules that process calibration-relevant signals.
The device to be transported should be packed in a suitable protective packaging, preferably in its
original packing.
Repairs may only be carried out by your supplier's service organisation. You will find a list of the
service network on the address page of these operating instructions.
When repairs are required, please always enclose a description of the error
(observations, type of malfunction, external circumstances etc.).
19.3

Disposal

The device contains electronic components and must therefore be disposed of as electronic waste.
Aquametro takes back its old devices and will dispose of them. Please also note your local regula-
tions in this respect.
