WM5-96 Instruction Manual
This function allows the operating modes selection of the digital
inputs. Choose the function DIGITAL INPUTS
(1) by means of the “
” keys and confirm with the “S” key. (2) Select the digital input (ex.:
A1=digital input 1 of slot A) by means of the “ ” keys, the instru-
ment displays the function of the selected input (the inputs are set on
REMOTE as default), press “S” to confirm the selected digital input.
(3)
From the list, select the operating mode to be coupled to the selected
digital input by means of the “
” keys, the functions are:
REMOTE (3) : the status of the digital inputs is displayed from the
instrument and retrasmitted (if requested) by the serial communication.
SYNC (SYNCHRONISM)
(3) : synchronises the calculation of the
“dmd” power by means of an external signal.
TARIFF LSb and MSb
(3) : This function allows the digital inputs to
control the tariffs in the energy metering. The combination of the input
status manages the tariff change as specified in the table
(18-1) . If only
the “MSb” (one digital input only) is selected, then the energy meter-
ing is possible with a maximum of 2 tariffs: the tariff change will only
be possible between tariff 1 and tariff 3. If only the “LSb” is selected,
then the tariff change occurs only between tariff 1 and tariff 2. The use
of both digital inputs (MSb + LSb) allows the management of tariffs 1,
2, 3 and 4. Press “S” to confirm the selection. Proceed, if necessary,
with the configuration of the other digital inputs.
(18-1)
TOTALIZERS (3) : This function allows the digital inputs to totalize the
gas, water (hot or cold) and the remote heating. From the totalizer
menu select: TYPE
(4) , to choose what the instrument has to totalize
(4a) GAS, HOT H2O (hot water), COLD H2O (cold water) or REMOTE
HEAT: in this case the WM5 counts the hot water by the digital input
through an external water counter but on the display the relevant value
is reported in “kWh”.
ENG. UNIT
(4b) , to choose the correct engeegniring unit (4b) to
associate to the totalizer selected before.
PULSES
(4c) , to set the pulse weigth (4c) , that is for each input pulse
the totalizer increases in the chosen value.
