Page 3: Overview Of System
The Cheetah system is installed with remote GPRS communications and data-logging facilities. This allows systems installed at sites to be remotely accessed by Quintex (as required) and the system/s performance operation can be monitored over a period of time. -

Cheetah system. Other VFDs may be accommodated with the use of a Cheetah Input/Output unit. DATA-LOGGER (RCDLU) The Cheetah Remote Communications Data Logger Unit provides direct communications to the Cheetah system via a GPRS modem. It can be accessed by the Quintex technical department. 671697... -

ENERGY EXHAUST TEMP OVERRIDE SCROLL DISPLAY Quintex Systems Ltd Finchampstead RG40 4QQ www.quintex.co.uk In normal operation the Cheetah Display LED screen will show the active extract motor power saving that is being made. It does not show the running speed of the system – running speed/s can be accessed by use of the SCROLL button. - Page 6 SCROLL BUTTON OPERATION. The Cheetah display unit has various screens that can be accessed in order to view the real-time operation of the system. Additional operating information can be accessed by pressing the SCROLL button, as shown in the diagram below. Cheetah systems installed with multiple canopies and/or fans may show more information on the display screen.

Page 8: Variable Frequency Drives
VARIABLE FREQUENCY DRIVES: Vacon 100: A Vacon 3-phase AC VFD is used to adjust the speed that ventilation fans run at by changing the frequency of the electrical supply voltage. Single-phase Vacon20 VFDs are also available when required and are covered later in this manual. - Page 9 (installed with specialist application software) that will operate correctly with Cheetah, when installed as a fully networked (LonWorks) system. Any replaced VFD will have to be configured into the Cheetah system network by a trained Quintex engineer, with the appropriate equipment.

Page 10: Vacon 100 Keypad Navigation (And Reset)
VACON 100 KEYPAD NAVIGATION (and RESET) The Vacon Inverters installed with the Cheetah system have a unique, bespoke software-application installed to allow them to operate with the digital (LonWork) communications of the Cheetah controls. The Inverter functions are checked during commissioning and should not normally require adjustment. If parameter adjustment is necessary this should be carried out with reference to the Vacon Instruction Manuals and the key setting parameters, by trained personnel. -
Page 11: Vacon 100 Key Settings
VACON 100 VFD KEY SETTINGS: During the commissioning of a Vacon 100 VFD the installation technician will set each VFD to operate with the motor to which it has been connected. It is essential that two key parameters are set correctly so that they match the specifications motor that the VFD is connected to. -
Page 12: Cheetah Input/Output Unit
CHEETAH INPUT-OUTPUT UNIT: Some ventilation systems have pre-existing VFDs that cannot accept digital (LonWorks) controlled instructions. Other VFDs, and devices such as EC fans, are not able to be LonWorks controlled. For applications of this type there is the option of installing a Cheetah Input-Output unit. The Input-Output unit has been specifically designed to convert digital (LonWorks) communications signals to analogue control signals (it is a D-to-A converter). - Page 13 DETAILED DESCRIPTION OF CHEETAH INPUT/OUTPUT TERMINALS: Analogue OUTPUT (0-10V) control signal [Available on terminal 6 – (WHITE conductor), with terminal 5 – (BLACK conductor) as the ground] This output provides the reference signal to an external device and is the commanded (percentage) fan running speed instruction from the Cheetah system.

Page 14: Single Phase (230V) Vfd
SINGLE PHASE (230V) VFD Single phase motors can be controlled by the Cheetah system with the use of a Vacon20 VFD. The Vacon20 has been specially adapted to run a single-phase (230V) AC motor. The connections and parameter settings for the installation are shown below. Alterations to the configuration and parameters should only be made by (or in association with) a trained technician. -
Page 15: Maintenance
MAINTENANCE Cleaning Optic Sensors The Cheetah laser optic sensor and related circuit boards are contained within stainless-steel enclosures – with (internal) dirt-repellent clear covers installed over the laser apertures. It is recommended that the optic sensors are wiped (with a clean damp cloth) once a week to maintain a ‘clear window’. Sustained direct pressure-jet washing of the laser aperture cover areas should be avoided. -
Page 16: Error Codes (Cheetah Display)
AIR HANDLING SYSTEM: The Cheetah system relies on the equipment that it is controlling (the extract and supply ventilation air systems) to be in a good state of operational order so that it can operate at optimum efficiency and produce the best results. It is expected that the ventilation systems are sufficiently maintained;... -
