Input – Output modules
Regarding the module programming, two versions exists:
•“Factory preprogrammed” modules: terminal function is burned in the module memory, meter automatically
acccept the module setting, terminals are denotated according to the VDEW denotation, modules could be
reprogrammed only in the factory or with special factory tool – Module Programmator
•“Empty” modules: modules are programmed as empty, terminal function is defined by meter parameters – meter
defines the terminal function, terminals are denotated as T1, .. Tn for outputs and I1, In for inputs
When moudule is inserted into the meter, cursor IM must be ON. If it blinks, module is not programmed properly or it is
not programmed at all. Module must be sent back to the factory.

Communication modules
Regarding the module programming, two versions exists:
•“Factory preprogrammed” modules: communication parameters are burned in the module memory, meter
automatically acccept the module setting, modules could be reprogrammed only in the factory or with special
factory tool – Module Programmator
•“Empty” modules: modules are programmed as empty, communication parameters could be changed by meter
parameters
When moudule is inserted into the meter, cursor CM must be ON. If it blinks, module is not programmed properly or it is
not programmed at all. Module must be sent back to the factory.
Each module has two independend communication interfaces:
•primary
•secondary

Primary and secondary communication interfaces are defined by the hardware in the module. Denotation expresess,
which interface is primary and which is secondary.
Communication module MK-2-3 (RS-232 & RS-485) :
Primary interface (RS-232) Secondary interface (RS-485)
Meter enables simultaneously reading via the both interfaces at the same time. Secondary communication interface is
shared with IR optical interface – when communication runs via optical probe, communication via interface in the module
is not possible.

Modules composed of primary interface (modem+CS+RS-485 – these two interfaces are intended for multidrop
communication) and secondary RS-485 interface.
Meter enables simultaneously reading via the both interfaces at the same time. Secondary communication interface is
shared with IR optical interface – when communication runs via optical probe, communication via interface in the module
is not possible.

Note: ISKRAEMECO suggest, that primary communication channel on multi-drop meter is used for cascading.

“No power reading” – meter is powered via SONDA 6 optical interface. SONDA 6 could be connected to the portable
computer – in such case is possible to read meter manually via LCE or reading and programming (parameters and time
setting) with MeterView.
SONDA 6 could also be powered via soecial battery pack. In such case it is possible to read meter only manually via
LCD.

2. Installation
To install meter follow next steps:
1 - Adjust hook height to fit installation position of the meter. Sliding hanger enables installation for all fixing dimensions
from 165 to 230 mm.
Fig. 18: Adjustable hook at meter back
2 - Fasten the meter to the measuring spot by three screws.
Fig. 19: Screw positions
3 - Connect measuring, input and output circuits and communication cables in conformity with the connection diagram
stuck inside the terminal block cover on the meter and modules.

4. Connect inputs, outputs and communication interfaces.
5. Install the terminal block cover and fasten it by two screws. Seal the terminal block cover screws by wire and seal.
6. If reset key has to be locked, hang up the overhang and lock it up. The overhang hole diameter is 5 mm.
7. Power-up the meter. By connecting to the voltage the light emitting diodes illuminate. After 3s measuring data from the
auto-scroll sequence are cyclically shown on the display.
8. Select GRID menu on the meter LCD and check phase voltages, currents, frequency and phase angles:

3. Checking the meter
Voltages
The meter enables detection and alarming of the presence of phase voltages. Presence of voltage and phase sequence
is marked with L1L2L3 characters in the LCD.
•If all three symbols L1L2L3 are displayed, it means that all three phase voltages are present.
•If cursors L1L2L3 are blinking, phase sequence is not correct (because of natural connection, the reactive energy is
also properly measured).
•Any not displayed symbol (L1, L2 or L3) means certain phase voltage is not present ot lower than predifined value Un
– 90%
•When one phase voltage is over or under the predefined limits, the AV status starts to blink. In such case check the
nominal - alarm voltage.
