2 Function description
General
The Vitobloc 200 CHP units can be unidirectionally remotely monitored by means
of TeleControl LAN. Status information and fault messages can be displayed.
In order to acknowledge faults remotely, a bidirectional connection is required,
which is also available as a retrofit solution for modules that have already been
delivered.
Two retrofit kits have been developed for the possibility of remote
acknowledgement. They are based on the controllers BBS 3000 1) and BMS 2007,
which offer different communication channels.
It is therefore necessary to check in advance which unit with which controller
should be extended to include the possibility of remote acknowledgement, so that
the corresponding retrofit kit can be ordered.
Operating principle
The Vitocom 300 LAN 3 device included in the remote reset retrofit kit provides
the reset command for fault acknowledgement as a binary signal via an internet
connection.
For this purpose, the Vitocom 300 LAN 3 is connected to the VITODATA server
via the internet. When the digital output ON/OFF is actuated, the corresponding
switching command is sent from VITODATA to the Vitocom 300.
The Vitocom 300 then switches the potential-free "DO" output, which connects the
digital input for remote acknowledgement on the CHP unit display via a relay.
System BBS 3000
The binary signal for fault acknowledgement is read in via a gateway. The reset
command is evaluated and carried out via the display to be replaced.
System BMS 2007
The binary signal for fault acknowledgement is evaluated by an extended version
of the display and the reset is carried out. For this purpose, the existing display
must be replaced with the display from the retrofit kit.
Fault acknowledgement
If there is a positive edge at the reset input of the new display, pending errors are
acknowledged and the CHP unit is switched to automatic mode.
If the condition that triggered the fault (e.g. battery undervoltage) is still present,
the fault is reset immediately or after internal monitoring.
Note
1) Applicable to the BBS 3000:
Only modules with touchscreen can be equipped with a remote reset.

Wall mounting
The enclosure of the retrofit kit is designed for wall mounting.
The wall brackets must be mounted on the enclosure for this. For this purpose,
expansion plugs are used, so that the mounting plate does not need to be
removed.

5838316 GB
Positioning the
control panel
The cables are inserted from below in such a way that a minimum height must be
observed.
Install the control panel in a suitable place. Ensure that the installation does not
cause any hazards (suitable working height, no impact point in the passage area,
suitable ambient conditions).
Control panel dimensions
Electrical installation
Before starting work, switch off the power supply to the unit and check that it is
voltage-free.
For the connection of the unit controller and the retrofit kit for remote
acknowledgement, the cables or leads listed in the bill of material must be used in
accordance with the wiring diagram. The stripped wire ends must be fitted with
wire ferrules.
The cables or leads are routed outside the unit using standard installation
material, whereby the existing cable-carrying systems should be used.
As a rule, ensure that this wiring does not give rise to a hazard that could cause
an accident.
Carry out the wiring in accordance with the corresponding wiring diagram.
After completing the cabling and wiring work, the wiring must be checked for
correct connection.
Caution when switching the power supply back on!

5 Operation
5.1 General design and operating information
Ensuring the safety
of the system
The operator must ensure that people are not endangered and that no other
hazards arise during the remote acknowledgement of faults.
The operator must make a note in the local and operational risk assessment
and, if necessary, take measures to reduce possible hazards (operator obligation
according to the German Operational Safety Ordinance (BetrSichV)).
We hereby expressly refer to these operator obligations.
When remote acknowledgement is activated, the following must always be
ensured:
•the CHP unit is operated in automatic mode,
•remote acknowledgement with the remote start option can be selected
separately and is enabled,
•a remote start request can only be initiated by a single control device.
Locking of remote
start/remote
acknowledgement function
The emergency stop button must be pressed and the key removed so that the
maintenance personnel working on site can exclude the possibility of an
unexpected CHP unit start-up. There is therefore no risk of the system starting
up.
The safety instructions which are obligatory according to the technical
description/operating instructions also remain valid when using the remote
acknowledgement function.
This applies in particular to the use of the complete protection equipment (e.g.
silencer hood panels).
System signs
Systems that can be remotely controlled and therefore do not have a start time
visible on site must be marked with a warning sign "Warning of automatic start-
up" (sign W018 according to ASR A 1.3) on the separating protection equipment,
in accordance with German accident prevention regulations (UVV).
The operator must select a sensible location for the warning notices in
accordance with the local and operational risk assessment for the system.
Depending where the system is installed, we recommend attaching appropriate
signs to the silencer hood of the CHP unit and/or the entrances to the CHP plant
room.

Restrictions
Usage charges
Application with several
CHP units
In principle, the natural gas modules of the Vitobloc 200 series are fail-safe.
Faults in the system or its components and unsuitable operating conditions (e.g.
excessively high ambient temperatures) lead to safe operating conditions. In
general, a fault message can therefore be assumed to pose a hazard to the
operation of the machine or the surrounding environment.
An assessment of the situation on site is generally preferable to remote
acknowledgement without knowledge of the status of the unit.
Since repeated remote acknowledgement can result in additional hazards
(e.g. repeated acknowledgement of the fault message "Oil pressure min."),
the possibility of remote acknowledgement must be limited to personnel
trained by Viessmann Kraft-Wärme-Kopplung GmbH and only used in
conjunction with remote monitoring (TeleControl LAN) in order to be able
to assess the condition of the CHP unit.
Remote acknowledgement may only be carried out by internal Viessmann
personnel for systems that are maintained by means of service contract 300.
Please note: Every remote acknowledgement process is logged for safety
reasons!
There are no usage charges for utilising the Vitodata 300.
If several CHP units are retrofitted for remote acknowledgement within one
system, the EM301 extension module must also be used.

The acknowledgement takes place when the relay changes from the open to the
closed state. This means that the relay must be opened again after each
acknowledgement procedure before another acknowledgement is possible. After a
successful acknowledgement, the CHP unit is switched to automatic mode if no
further faults are pending.
