1. 4 1 Intended Product Application The AP devices are designed and manufactured for control applications and air quality compliance in commercial buildings and manufacturing plants i e detection and automatic exhaust fan control for automotive maintenance facilities enclosed parking garages engine repair shops warehouses with forklifts fire stations tunnels etc 4 2 Installers Responsibilities It is the installers responsibility to ensure that all devices are installed in compliance with all national and local codes and OSHA requirements Installation should be implemented only by technicians familiar with proper installation techniques and with codes standards and proper safety procedures for control installations and the latest edition of the National Electrical Code ANSI NFPA70 It is also essential to follow strictly all instructions as provided in the user manual 4 3 Maintenance It is recommended to check the AP device regularly Due to regular maintenance any performance deviations may easily be corrected Re calibration and part replacement in the field may be implemented by a qualified technician and with the appropriate tools Alternatively the easily removable plug in device card with the sensor may be returned for service to Automatikprodukter 4 4 Limited Warranty Automatikprodukter warrants the devices for a period of one 1 year from the date of shipment against defects in material or workmanship2. Should any evidence of defects in material or workmanship occur during the warranty period Automatikprodukter will repair or replace the product at their own discretion without charge This warranty does not apply to units that have been altered had attempted repair or been subject to abuse accidental or otherwise The warranty also does not apply to units in which the sensor element has been overexposed or gas poisoned The above warranty is in lieu of all other express watranties obligations or liabilities This warranty applies only to the AP devices Automatikprodukter shall not be liable for any incidental or consequential damages arising out of or related to the use of the AP devices Page 17
3. Communication to a Transmitter For communicating with a transmitter the TDAO3 Software has to be informed about the address of the attached transmitter There are two possibilities 1 Ihe transmitter address is known and the transmitter has to be addressed by this address The switch at the black cable has to be in centre position 2 When using the Service Mode you have to put the switch at the black cable in outside position Then the transmitter is always addressed with address 246 For establishing the connection to the transmitter you have to enter the corresponding address into the field Current Sensor Address and to confirm it with Enter Connection Status e Close Current Sensor Address Pa Sensor Search Sensor hound Now the transmitter is addressed by the TDAO3 Software As a proof the progress bar in the lower part of the main window moves on and the red little lamp at the USB Nano 485 converter flashes Tx If the transmitter doesn t respond the progress bar will only move gt ESPERES slowly and there will be an error message at the main window No a ES communication gt No communication If the transmitter responds the progress bar will move faster and the green little lamp at the USB Nano 485 converter will flash Rx The data coming from the transmitter are displayed in the window Transmitter For opening this dialog you have to click on the cogwheel symbol on the tool bar or to choose
