- required current limits of the 1-st and 2-nd current outputs are set by switching the jumpers
“I1” and “I2” into one of the following positions: “4
-
20 mA” or “0
-
20 mA”.
If the calculator is equipped with universal interface module (including M-bus, CL, RS-232
interfaces and two pulse outputs):
- M-bus, CL or RS-
232 interface is activated by plugging in the jumpers “CL –
M-bus
–
RS-
232” in such way, that required interface type appears beside the termin
al pins
“73…75”.
Marking on the jumper board will show the functional description of the pins.
-
required type of pulses output are set by switching the jumpers „+P1 +P2 GND“:
Galvanically isolated passive pulses outputs - not jumpers
Not galvanically isolated active (+
18 V) pulses output „Puls1“
-
„GND“ and „+P1“
Not galvanically isolated active (+
18 V) pulses output „Puls2“
-
„GND“ and „+P2“
Optional modules. Exchanging of modules
Calculator may be delivered with 230 V power supply module or 3,6 V battery power supply and
one of the four external communication modules. Possible options are listed in the paragraph 3.
Communication module types and specific application restrictions are described in the Table 7.
Table 7
Communication module type Purpose, functions Application restrictions
SKS43
M-bus
Allows connecting the device to M-bus
network (up to 254 devices in parallel) in
distance up to 2 km Suitable for all power
supply options
SKU45
Universal with two current
outputs
User may choose one of three available
interfaces (M-bus, CL, RS-232).
Two current outputs are available, with
user-
selectable current limits ( “4
-20
mA” or “0
-
20 mA”)
Only for 230 V power
supply
SKU46
Universal with two pulse
outputs
User may choose one of three available
interfaces (M-bus, CL, RS-232).
Two pulse outputs are available, with
user-selectable type - galvanically
isolated passive pulses or not galvanically
isolated active (+18V) pulses Only for 230 V power
supply
SKS48
Special type, compatible with
RS-232 interface
Distance up to 15 m. Designed to connect
equipment with RS-232 interface, where
RTS +9...+12 V and DTR -9...-12 V
signals are used Suitable for all power
supply options
Mains supply or battery module is in the bottom part of the calculator, on the right side beside the
terminal block, while communication interface module is on the left side.
Modules can be exchanged on-site, by opening the lid, unscrewing the appropriate fixing bolt and
pulling out the module from the connector.

Disconnect the equipment from mains supply before replacing modules!
7.5 Verification of installation and set-up
After installing the heat meter, let measured fluid flow through the flow sensor, and switch on the
power supply. Measured parameter values should be indicated on the display, if the heat meter
(calculating unit, flow, pressure and temperature sensors) is installed correctly. If measured parameter
values are not displayed correctly, it is necessary to verify the installation.
