1. General
Arimatic 151 control centre is designed to control 40-150kW bio heating
systems supplied by Ariterm Oy. The centre is suitable for controlling the
HakeJet, BioJet and MultiJet burners and the BioComp boiler. There are
several options available for the control centre, including ash auger control ,
residual oxygen (Lambda sensor) and GSM alarms.
The system is controlled with programmable logic (Siemens S7-1200). The
interface is a 4.3" graphic touch screen display. Arimatic 151 system burners
use energy-efficient and easy to adjust EC combustion air blowers.
2. Transport, storage and package opening
The centre is delivered with a platform. The package should be opened as
close to the installation site as possible. The centre should be stored indoors.
It is important that the recipient check the condition of the centre before

4. Installation and commissioning
Install the centre in a place where the system is easy to use and cables are
easy to install. The centre should have 1 m of space in front of it.
Electrical connections should be done according to the wiring diagrams. The
wiring diagrams also indicate accessories. If no safety devices are connected
to the system, the respective terminal block should be short-circuited.
Example: Dry-boiling protection is not required for systems under 100kW. If
there is no dry-boiling protection, a permanent loop should be installed
between terminal blocks 10X1: 24 V DC and 41.
Current limits for the thermal overload relays and motor protectors should be
set according to the current value consumed by the motor. The current values
are indicated in the type plate of the motor.
The centre can be started once all electrical connections are completed. By
accessing the OPTIONS -menu from the SETTINGS -page, you can configure
system devices, such as Ash screw 1. Do not select functions/devices not
included in the system, because they may cause unnecessary alarms. NOTE!
The OPTIONS -menu can be accessed with Maintenance -level codes.
After completing system configuration, check the system for any alarms
caused by, for example, uninstalled or incorrectly connected sensors.
Functionality of all safety devices, such as emergency stop buttons,
thermostats and hatch switches must be tested/checked.
Then, check the rotation directions of screws and test all functions (fans,
screws/augers) in the MANUAL -menu.
The system has factory default settings, but certain settings, such as the
EFFECT -settings should be adjusted according to the fuel (Check chapter
14). Adjustments should be made by means of a flue gas analyser in order to
ensure clean combustion. Additionally the STORAGE AUGER -settings must
be adjusted based on the size of the funnel between the feeding auger and
the storage auger.
NOTE! If the system is equipped with automatic ignition, the AUTOMATIC
IGNITION -settings must always be defined case-specifically. The settings
should be made by an authorised maintenance professional during
commissioning. Incorrect ignition times and settings may result in a failed
ignition and halt the system.

5. System description
The system is started with the AUTOMATIC -button, after which the ignition
pages open. If the flame detection system detects a flame in the burner head,
the burner switches to effect mode. After the ignition phase, the burner
switches to effect mode, during which the effect of the burner is adjusted
according to the required heating power. The automatic system attempts to
maintain the boiler water temperature at the set level. If a high level of heating
is not required, but the boiler water temperature increases excessively, the
burner will activate the upkeeping mode.
The burner uses the upkeeping mode to maintain ember in the burner head.
When the boiler water temperature decreases, the burner returns to the effect
mode. The user can stop storage operation and empty the burner screw by

Figure 8. Manual ignition -page - Burner equipped with automatic ignition.
Run the burner auger with the BURNER SCREW -button so that the burner
head has enough fuel. The storage auger automatically fills the funnel while
the smoke gas fan maintains an underpressure in the combustion chamber.
Ignite the fuel and turn on combustion air fans. Wait for the fuel to properly
ignite. You can add more fuel to the burner head. When the flame is large
enough, the Ignition 1 -phase can be acknowledged with the MANUAL
IGNITION 2 -button, after which the system will proceed to the Ignition 2 -
phase.
During the Ignition 2 -phase, the burner is run at a fixed effect level, which the
user can adjust. In this case, the fuel feed and fanning is controlled
automatically. NOTE! During the first heating process, the burner should
be run at low power (21-30%) for approximately one hour in order to
remove humidity from the burner ceramics. When the flame detection
detects a flame, a flame symbol will be displayed . Then you can activate
automatic effect adjustment by pressing the MAN. IGNITION READY -button.
You do not need to wait for the flame information. The Ignition 2 can be
acknowledged earlier as well.
The flame information is provided by the flame detection thermostat
measuring the temperature of smoke gas. When the smoke gas temperature
exceeds the thermostat limit (approximately 70°C), the flame information is
displayed. The flame detection phase (10 min.) is activated after the Ignition
2-phase. During this phase, the smoke gas temperature increases over the
set temperature.
If the system is equipped with automatic ignition, the flame data is monitored
during the ignition with an optical flame detection sensor.

the funnel and the boiler is ventilated before ignition. When the funnel is full,
the burne screw runs for the duration of the Burner screw filling time (long)
-setting, feeding an appropriate amount of fuel to the burner head. NOTE! If
the system is halted by an alarm while the burner screw is full of fuel, the user
can select a short filling time during ignition. During the short filling, the screw
will feed the burner head for the duration of the Burner screw filling time
(short) -setting.
The hot air gun and combustion air fans operate for the duration of the
Ignition step 1 -setting. If the flame detection detects a flame, the burner will
activate the Ignition 2 -phase. The optical flame detection sensor must detect
a flame during the duration of the Flame delay -setting in order to activate the
flame data. If the flame detection fails to detect a flame during the Ignition
step 1 -time setting, the fans and ignition stop and the Alarm! automatic
ignition alarm is displayed.
During the Ignition 2 -phase, the burner runs at a power level configured in
the Burner screw -setting for the duration of the Ignition step 2 -setting. After
this the burner automatically activates the effect mode. If the flame disappears
during the Ignition 2 -phase, the Alarm! Automatic ignition -alarm is
displayed.
Power settings for the burner screw and the combustion air fans during the
ignition phases are set in the BURNER SCREW/PRIMARY
FAN/SECONDARY FAN -setting pages.
The hot air gun can be activated by pressing the IGNITION UP->EFFECT -
button once the burner switches from Upkeep to Effect mode.
