adaptor to an outlet further away or to the power supply panel of
the boiler. Do not use a USB extension cable.
The OK LED should light up green.
The corrosion monitor carries out a measurement every 20
minutes. A corrosion rate is determined every 7 hours. An indicative
corrosion rate is calculated for a few days, which will be sufficiently
correct after seven days to generate an alarm, if necessary.
2. Enter the date of the installation on page 102 .
3. Using the black terminal connector, the integrated, volt-free
contact can be connected to an external safety circuit (e.g. building
management, external signalling device or the safety circuit of the
heat source). The circuit is closed in case of normal operation of
the Risycor, and is interrupted in case of an alarm, as well as when
there is no power supply.
CAUTION! The volt-free contact with a normally open contact
is closed during the operation of the corrosion monitor. In the
case of an alarm, the volt-free contact breaks the external safety
circuit of 48 VDC, 100 mA or 48 VAC RMS 80 mA, max. 350 mA @
<10 ms
NOTE: If the safety circuit of the heat generator is connected, and
the mains supply to the corrosion monitor fails (e.g. faulty cables,
power supply, fuse, etc.), the heating system can no longer
work. In this case, the 'ALARM IGNORE' function will also not
work. This can be rectified by a bridge in the terminal connector.
The volt-free contact will thereby be closed, so that the heat
generator can function again. The corrosion monitor will still not
function, however.
4. Set the limit for the annual corrosion rate. The threshold value is
pre-set to 24 μm per year. This value can be changed via the Resus
Dashboard software (see Chapter 9, Read-out).
