10.5 USB Plug-In Module (for M-Bus slot)
Order number: 68504688
Using this plug-in module, the calculator unit can
be connected to a PC / Notebook or hand-held
computer with USB input. If an M-Bus plug-in
module is installed, this must be removed
beforehand. A driver is required for connection,
which is also supplied with a data carrier. The
description of the driver installation is given there.
10.6 LONWORKS
®
-FTT10A
Using this plug-in module, the meter can be
connected via a LONTALK
®
protocol to
appropriate instrumentation. A driver software is
supplied on a mini-CD. For more detailed
information, refer to Datasheet LH 6132 DE.
10.7 Inserting the Plug-In Modules into the
Calculator Unit
In each calculator unit has a slot for the M-Bus
modules (at the back, right) and the telecounting
modules (at the front, left).
The approved
modules for the calculator unit must only be
installed into the slots provided for them.
Figure 16: Installation of the plug-in modules
During assembly, insert the plug-in modules into
the left and right guide made from white plastic
(Figure 16).
The contact pins must not be bent and easily glide
in the contact bushes provided for them.
Guide the connecting cable through the hole in
the moulded rubber part and establish strain relief
using a cable-tie. Now connect the wires to the
appropriate terminals and replace the moulded
rubber part.
10.8 Combined Heat / Cooling Meter (Order
Option)
Designation:
PolluTherm H or PolluTherm X H
With this option, the PolluTherm switches
between metering of the heating and cooling
energy with the aid of an automatic switching
point. The factory setting for switching to cooling
metering is:
Flow temperature
≤
25 °C
and
Negative temperature differential
≥
- 0.15 K
To switch back to warm metering, the following
applies:
Flow temperature > 25 °C
and
Positive temperature differential
≥
0.15 K
As required, this switching point can be adapted
on site, using the service software MiniCom, from
Version 3.6.0.65.
10.9 Optional Integrated Data Logger (Order
Option)
If the option is installed, the housing cover has the
additional inscription "Data Logger".
The integrated data logger saves consumption
values at a time interval and actual values
(energy, flow, temperatures) that can be selected
(3 to 1440 minutes). The logger data can be read
out through the optical interface, M-Bus using the
service software MiniCom, from Version 3.6.0.65.
The time setting (factory setting: 60 minutes) can
also be changed using the MiniCom, from Version
3.6.0.65.
For connection to a PC, either an optical data
coupler (refer to Section 10.1.) or a USB plug-in
module can be used.
10.10 Conversion of Battery Device to Power
Supply Device
Before converting, observe the following and also
carry out in this sequence:
Before the supply battery is removed, the
calculator module must be removed from the
calculator unit. For this, open the cover of the
calculator unit and remove the right retaining
screw (screwdriver: Torx 6) under the plastic
cover (user seal, refer to Figure 17).
Subsequently, carefully pull the calculator
unit module upwards, out of the plug-in
connection. The left and middle seal must not
be removed (loss of calibration)!
Insert the backup battery AA 3,6V
(68504998) into the rear of the calculator unit
module. The battery is required to secure the
date and for temporary operation when the
mains power is interrupted.
Remove the main battery (D-cell) and insert
the mains module.
