The
response threshold
for flowrate measurement is 40 % with reference to the minimum
flowrate by default (see Table
Pressure loss
). It can be ordered depending on the MLFB or
changed subsequently using the PappaWin software in the range 5..100% in steps of 5%.
For the
returning heat meters
, the
Configuration Instructions
and the
Installation and Service
Instructions
contains the note “The lithium batteries must be properly returned”.
Notes should also be included in the “Start-up guide for heat meters”! (“Practical help from
sales”).
Sensor installation
The sensor must be installed in such a way that it is in the flow path “after the heat meter”.
Sensors provided by customer
In the case of sensor provided by the customer (max. cable length 5 m – an extension is
impermissible!) the 2
nd
and 3
rd
sleeves from the left must be cut to match the cross-section of
the cables.
Unlatch the housing cover by pressing in the side tabs and remove it. Route the cable of the
flow sensor from outside through the 2
nd
sleeve, the cable of the return sensor through the 3
rd
sleeve.
Wire-end
ferrules
Connect the conductors as shown on the circuit diagram printed on the unit. The 2-wire
connection is made at terminals 5/6 and 7/8. No cable shield must be connected to the heat
meter. Then inset the sensors in the pockets, ball valves, or T-elements and seal against
tampering.
If an error message “F8” is shown, it can be reset via the parameter setting menu (see Page 7).
Replace the housing cover and press it in gently until you hear all the tabs latch.
The
service menu
is called by opening the cover and pressing the service button for 3 s. It is
possible to advance through the display loop using LCD button 1. The required function is called
by pressing LCD button 2.
Call the
test mode menu
Call the
parameter setting menu
Return to normal mode
Return to normal mode is performed automatically after no more than 15 hours.
A
set day
defines the data on which the following values are stored to be called up later:
−
Current value for the missing time,
−
Current value for the flowrate time,
−
Current value for volume,
−
Current value for quantity of heat,
−
Current value for the tariff register,
−
Maxima with associated time stamp.
