Kamstrup A/S · Technical description · 5512-2360_A1_GB_02.2019
Figure 3: For the use of 2-wire sensor pair, install supplied short-circuit jumper marked in red. For the use of internal
24 VDC supply marked in orange, MULTICAL® 803 must be delivered with supply type A or C. Additional connection
boards for flow sensors with 24 V active/passive pulses (type P) are shown in the upper right corner (6699-045).
4.5 Commissioning
Carry out an operational check when the energy meter has been fully mounted. Open thermoregulators and valves
to enable water flow through the heating system. Use the front keys on MULTICAL® 803 to change the display view
and check that credible display values for temperatures and water flow are shown. Read more about the MULTICAL®
803 display content in paragraph 3.4.4.
Using meters with Auto Detect Pt and/or Auto Detect UF
Note that MULTICAL® 803 has a built-in engagement delay of up to 20 seconds to ensure that all plug connections
between calculator top and base are established before a detection of Pt-sensors and/or ULTRAFLOW® X4 is
initiated.
4.6 EMC conditions
MULTICAL® 803 has been designed and CE-marked according to EN 1434 Class A and C (corresponding to
electromagnetic environment: Class E1 and E2 of the Measuring Instruments Directive) and can thus be installed in
both domestic, light industry and industrial environments.
All control cables must be drawn separately and not parallel to e.g. power cables or other cables with the risk of
inducing electromagnetic interference. There must be a distance of min. 25 cm between signal cables and other
installations.
