2 Safety

The monitoring and controlling system ISYteq is built according to the state of

technology and the recognized safety engineering rules.

Operate the ISYteq System only in fully acceptable technical condition for its

intended use. Observe all relevant safety instructions and precautions in the

operating manual. Use proper safety measures to prevent hazardous situations

which, if not avoided, could result in a threat to life and limb of the user or third

parties or damage the system itself, connected units, or other property!

Have all faults repaired by an authorized specialist without delay!

All remarks in this chapter are important and relevant to safety. Yet not all

information in this chapter is marked with special safety symbols.

2.4 Safety instructions: warning and danger symbols

The following symbols and notices are provided in appropriate places throughout this

document to designate the safety instructions.

2.4.1 DANGER - Death/serious irreversible injury

Indicates an extremely hazardous situation which will result in death or serious

irreversible injury, if the safety instruction is not followed.

Example:

Electrocution through hazardous voltage will lead to death or serious injury!

• Disconnect the unit from the power supply and ensure the power cannot be

switched back on.

• Ensure the unit is voltage-free and isolated, earth and short circuit the unit,

cover or shield off neighboring live components.

2.4.2 WARNING – Environmental or material damage

Indicates actions that can result in damage to equipment or property.

Examples:

Environmental Damage!

Heavily contaminated filters can have a negative impact on production processes.

Depending on the filtered-out materials, contaminated filters are therefore

classified as hazardous waste and must be properly disposed of according to the

prevailing guidelines and laws.

Damage to the unit!

If dampers are abruptly shut during unit operation, the unit can be damaged

beyond repair as a result of negative pressure or overpressure.

2.6 Safety-conscious work procedures

When working within range of mains voltage:

Electrocution through hazardous voltage will lead to death or serious injury!

• Disconnect the unit from the power supply and ensure the power cannot be

switched back on.

• Ensure the unit is voltage-free and isolated, earth and short circuit the unit,

cover or shield off neighboring live components.

For all kinds of work:

Risk of electrostatic discharge!

While carrying out adjustment work on the ISYteq control panel, make sure that

you discharge yourself statically before manipulating PC boards and installing

electrical components.

• Observe all assembly instructions for the ISYteq control panels.

• Fluctuations and imbalances in the supply voltage may not exceed the tolerance

limits specified in the technical data, otherwise functional failures and limit states

cannot be excluded.

3 Technical Description

3.1 Product features and functions

The ISYteq controller is a microprocessor-based, programmable electronic controller,

featuring a multitasking operating system, compatible with the FläktGroup controls

family of devices, which includes programmable controllers, user terminals,

gateways, communication devices and remote management devices.

These devices represent a powerful control system that can be easily interfaced with

most Building Management Systems (BMS) available on the market.

ISYteq has been developed to provide solutions for several applications in air-

conditioning, refrigeration and HVAC/R in general.

ISYteq controllers can be connected in an Ethernet LAN to other FläktGroup family

controllers.

Each device in the LAN can exchange digital or analog variables with all the others,

based on the application program used.

The built-in web server supports HTML standard.

Other innovative functions include the possibility to display the contents of the pGD1

terminal in the browser, and to display graphs of data recorded by the data logger in

real time.

The Integrated USB peripheral can be used to update the controller application and

web app, in the flash memory. It is also used to download the logs from the

controller.

3.4 Models of ISYteq Display Panels

3.4.1 ISYteq Touch 2.1

This Touch 2.1 control panel is designed as a compact user interface to the

FläktGroup controllers. Due to its size, it can be integrated into rooms more

inconspicuously. Despite its small size, it is a complete and powerful control panel

that supports almost all functions of FläktGroup controllers.

The user will only see the controls on the display whose functionality is reported by

the controller. Operating elements that are not required are hidden.

Figure 3: Touch 2.1 display with a white frame

3.4.1.1 Space requirements

The control panel is mechanically designed for indoor installation in a standard flush

box (68 mm). If the room temperature is to be measured via the integrated sensor in

the control panel, an installation with a standard surface-mounted device box is more

suitable.
