Installation of IMR module
(module code: 005)
There are three types of IMR modules (Fig. 27): with
radio interface (APAT 1312), with radio and cable
interface (APAT 1322), with cable interface (APAT
1332). Modules can be powered, depending on the
version, from their own battery or external power
source. Cable interface (terminal no. 34 and 35) can
be used to connect an active AMPLI antenna – cable
order does not matter. For the connection of external
power source (in the range of 4-16 V or stabilised 3.6
VDC) the following terminals are used: 31 – positive
pole, 32 – negative pole. The module supplied by the
manufacturer with its own power supply is in the sleep
mode. The APAT 13x2 module can be activated using
the SW1 diagnostic button (push and hold the button
for 5 to 7 seconds, then let go). If APAT 13x2 is a version
without its own power supply or if the system is awake,
push and hold the diagnostic button for 5 seconds to
check the operating mode. Correct operation is sig-
nalled with 4x flash of the LED.
NOTE! IMR modules can be mounted only in the con-
nector marked with number 1 (Fig. 9).
Installation of the impulse input/output
module
There are two types of the pulse input/output modules:
1) 2 pulse outputs module (module code 016), the
module is shown in figure 28,
2) 2 pulse inputs and 2 pulse outputs module (module
code 080), the module is shown in figure 29.
Depending on the version the modules can be supplied
from the Faun calculator or the external power source.
The external power source is connected to terminals 97,
98. The polarisation of the connected power can be any.
Figures 28 and 29 present the module supplied from the
external power source. When the module is supplied
from the calculator it is not equipped with the power
terminal. Due to the high average current consumption
by the pulse outputs it is recommended to use modules
supplied from the external power source.
The pulse inputs are connected to terminals 65, 66 and
67, 68 and the signal from the pulse outputs is con-
nected to terminals 71, 72 and 73, 74.
The pulse outputs can operate in one of three classes:
OB, OC or OD (according to EN 1434-2). The output op-
eration class is configured during production and

cannot be subsequently changed. The individual pulse
output classes have different maximum pulse frequen-
cy, pulse duration and interval.
The pulse output generates the number of pulses which
is proportional to the increase in (main, cool or tariff)
energy or volume with the selected pulse value. The type
of the pulsed data and the pulse value can be config-
ured in any manner for each output.
Installation of 2 analogue outputs module
(module code: 256)
The analogue output module requires an external
source of power. There is a galvanic isolation between
the calculator and the module. The module is available
in three versions with two current outputs 0/4 ... 20 mA,
two voltage outputs 1 ... 10V or one current output and
one voltage output. You can freely configure the ana-
logue outputs in such a way so as to output a status pro-
portionate to one of the momentary values: flow, power,
supply temperature, return temperature or temperature
difference. The status of the analogue output is updated
every cycle when momentary values are determined,
i.e. every 10 seconds during normal operation with flow
other than zero. For correct operation, it is necessary to
adjust the outputs in the module configuration.
Terminals 97 and 98 are to connect power supply of
the module. Analogue output terminals, depending on
workmanship, are described in the following way, for
the workmanship of:
1) 2 voltage outputs (Fig. 29):
– output 1 – terminal 87, reference to output 1 – ter-
minal 88,
– output 2 – terminal 89, reference to output 2 – ter-
minal 90,
2) 2 current outputs (Fig. 30):
– output 1 positive terminal – 80, negative terminal
– 81,
– output 2 positive terminal – 82, negative terminal
– 83.
3) 1 current 1 voltage output (Fig. 31):
– output 1 (voltage output) – terminal 87, reference
to output 1 – terminal 88,
– output 2 (current output) positive terminal – 80,
negative terminal – 81.
NOTE:
When the module is powered from calculator
power supply, due to max. load-carrying ability of power
supply, it is possible to install one analogue module
only.

Cable lining inside the calculator
The calculator has been designed to assist you in the
installation process as much as possible. In the base of
the device there are special “tunnels” that help in con-
nection cable lining. The IP54 version of the calculator
also features special pins preventing the cable from
being ripped out. In IP65 and IP68 models this task is
performed by cable grommets. Figure 35 shows how
cable is to be lined inside the device.
