1 - SAFETY CONSIDERATIONS
1.1 - Safety guidelines
Installation, start-up and servicing of equipment can be
hazardous if certain factors particular to the installation are
not considered: operating pressures, presence of electrical
components and voltages and the installation site (elevated
plinths and built-up structures).
Only properly qualified installation engineers and highly
qualified installers and technicians, fully trained for the
product, are authorised to install and start-up the equipment
safely.
During all servicing operations all instructions and
recommendations which appear in the installation and
service instructions for the product, as well as on tags and
labels fixed to the equipment and components and
accompanying parts supplied separately, must be read,
understood and followed.
Failure to comply with the instructions provided by the
manufacturer may result in injury or product damage.
• Apply all standard safety codes and practices.
•
Wear safety glasses and gloves.
•
Use the proper tools to move heavy objects.
•
Move units carefully and set them down gently.
1.2 - Safety precautions
Only personnel qualified in accordance with IEC (International
Electrotechnical Commission) recommendations may be
permitted access to electrical components.
It is particularly recommended that all sources of electricity
to the unit be shut off before any work is begun. Shut off the
main power supply at the main circuit breaker or isolator.
IMPORTANT:
This equipment conforms to all applicable
codes regarding electromagnetic compatibility.
RISK OF ELECTROCUTION! Even when the main circuit
breaker or isolator is switched off, specific circuits may still
be energised as they may be connected to a separate power
source.
RISK OF BURNS! Electrical currents may cause
components to get hot. Handle the power cable, electrical
cables and conduits, terminal box covers and motor frames
with great care.
2 - CONTROL OVERVIEW
2.1 - System functionalities
The Touch Pilot system controls the start-up of the
compressors needed to maintain the desired heat exchanger
entering and leaving water temperature.
The control panel serves as a user interface and a configuration
tool for controlling the operation of the unit. Touch Pilot
constantly monitors safety devices that protect the unit against
failure and guarantee its optimal functioning.
2.2 - Touch Pilot components
The controller manages a number of mechanisms that allow
the unit to operate effectively, including the following:
• Compressor start-up to control the water loop
(screw compressor technology)
• 7’’ touch screen as standard (Touch Pilot)
• BMS connection
• Diagnostics, e-mail transmission
•
Web connectivity
• Energy Management Module (optional)
•
Hydronic module, variable-speed pump control (optional)
•
External fixed-speed or variable-speed pump control
• Remote unit management
• Energy optimization, power/energy monitoring
• Maintenance schedule management
• Communication protocols (CCN, BACnet, Jbus, LON)
2.3 - Operating modes
The control system can operate in three independent modes:
• Local mode:
The unit is controlled by commands from
the user interface.
• Remote mode:
The unit is controlled by dry contacts.
• Network mode:
The unit is controlled by network
commands (CCN or BACnet). Data communication
cable is used to connect the unit to the RS485
communication bus or IP connection.
When the control operates autonomously (Local or Remote),
it retains all of its control capabilities but does not offer any
features of the Network.
IMPORTANT:
Emergency stop!
The Network emergency stop command stops the unit
regardless of its active operating type.
