1. Very high gas concentrations The measuring method of SAFEVADER series detector based on heat produced by reaction on the oxidation of a flammable gas when pellistor sensor used. There is not enough oxygen in the sensor to perform oxidation process correctly in case of high gas concentrations. Hence the measuring signal decreases at high gas concentrations and even can lead to measuring signal within the measuring range again.
Introduction The Prosense comprises a gas detector body and a choice of sensors heads for detecting flammable gases, toxic gases and oxygen. The construction of Prosense SAFEVADER Series detectors allows it to be used in areas not classified as hazardous.
Detector body The detector enclosure has two cable entries located at the bottom of enclosure for connecting the power source, signal output and relay contacts to associated signalling equipment. There are two mounting holes incorporated into the transmitter housing. Diagram 2: Detector body and size (mm) Installation Gas detectors should be mounted where a potential hazard of gas is most likely to be present.
• in places where temperature is outside the admissible operating range, • corrosive environments, • inside air vents. • environments where silicon can be found. Prosense SAFEVADER series detector has two mounting holes on detector body to fix detector directly to a surface: Mounting hole Mounting hole Diagram 3: Mounting holes PRS-UM-SV-EN-Rev1.0-16.12.2022...
Observe precautions for handling electrostatic sensitive devices. SAFEVADER Series Detector must be powered by a SELV power supply. The SAFEVADER Series Detector shall be supplied by an isolated power source which fulfils the requirements of: • Limited-Energy Circuit in accordance with UL/CSA 61010-1, •...

Example; Diagram 4: Field cabling The controller or power supply is supplying a nominal 24VDC (V controller), the detector minimum allowable voltage is 12VDC (V detector min), therefore the maximum allowable voltage drop between the controller and detector is 12VDC; this means a voltage drop of 6V in each core (V+ core and V- core).
Detector grounding Internal Ground connection: Each detector has grounding screw which utilizes grounding for detector main PCB to detector body. The screw should be located correctly and fixed for all times. In case of any maintenance activity this screw should be checked and fixed to make sure for proper grounding.
4-20 mA output: Prosense SafeVader detectors can be connected to control panels on the market having 4-20mA input signal. Signal wiring from detector and the control panel should be carried out by shielded cables. Wires cross section depends on the distance between the control panel and the detector.
Relay Outputs: Prosense SafeVader detectors have three relay outputs to generate switching output in case of Fault and defined level adjustable two alarms named as Alarm-1 and Alarm-2. The relay outputs set to NO (Normally Open – De-Energised) position at factory. All relays use same common port marked with C label and all common connections are shortcircuited.
System Status The Prosense SafeVader detector has a screen to show status messages and measurement levels online. Also it has three LEDs to show power, fault and alarm status. If equipment is in normal condition the green power LED will blink with 1 second period and screen will show the gas that detector measuring, current level of gas detector measuring.
Indication of measured values Display screen shows the concentration level of the target gas in two ways. In the first, a numeric value is shown in the middle of the display in the units selected (PPM, %LEL, %VOL). The second concentration display is shown in the form of a bar graph representing the current concentration against full scale and in relation to the defined alarm levels.
provide switching output for defined alarm levels. Alarm-3 is only visual alarm and it is not integrated to relay module. Hence it is not possible to get switching output for Alarm-3. In case of an alarm, related alarm LED will lit and alarm information will be shown on the screen: ALARM METHANE 15 %LEL...
Analogue Output State: Analogue output of equipment provides state information to external devices via current level. The output provides signal between 0- 22mA: • Equipment provides meaningful measurment level between 4-20mA current level. The external device must evaluate 4-20mA current level as measurement level information. The evaluation of measuement level regarding a dangerous gas concentration must be performed by an external device.

Check the screen. It will run self check tests and report the results. All tests should end with OK. In case of any ERROR message contact Prosense. When test completed the screen will show monitoring screen with detector information and WARMUP message on status line.
Detector Settings Prosense SAFEVADER detector prepared at factory to work as standalone detector. User may want to change settings and alarm levels depending of the requirements. SAFEVADER detector screen can be used to change the detector settings. There are 3 buttons on display to perform menu operations which are Enter, up (Increase) and down (decrease).
Menu structure SAFEVADER Series Detector menu includes all necessary steps to setup detector and display information. Diagram 9: Main menu structure Page 23 / 41 PRS-UM-SV-EN-Rev1.0-16.12.2022...
Alarm Settings Alarm levels can be adjusted via using alarm menu steps. Once you reach the main menu the first option is alarm settings. Press Enter to move the alarm settings menu. A new menu listing alarm levels will be shown: 1.
ventilation fan kept activated after the measurement level falls below the alarm level. In such cases the off-delay feature can be used. The off-delay can only be defined in minutes. Configure User can change the parameters of detector depending of the usage such as date, time, password and detector address via configure menu.
User can adjust these values to desired values depending of the application requirements between 1 to 3.5 mA for Fault, Warm-up, Calibration, Inhibit and 20-22mA for Overrange. Display Parameters Detector display can be adjusted as per requirements. The display options are given in Display menu item 1.
User should remember the password to perform changes later on. If user forgets the password, detector should be returned back to Prosense to reset password. No Field operation is available to reset password at customer site.

Test Menu Options User can execute tests to check detectors functions. To perform tests select Test menu item via up and down keys then press Enter key. The screen will display test options: 1. Inhibit 2. Display 3. Relay 4. Analog Output 6.
select Relay option. Screen will display three options to test as there are three relays on relay module. Select the menu option related to desired relay test and press Enter key. 1. Fault Relay 2. Alarm 1 Relay 3. Alarm 2 Relay 4.
Calibration It is recommended to periodically carry out calibration to ensure correct operation. Prosense SAFEVADER series detector calibration includes two steps as zero and span calibration. It is possible to perform each step independently. Prosense recommends to perform both calibration steps to have correct calibration. Detector should be powered and stabilized for at least 4 hours before calibration.
If the password is wrong the display will return to measurement screen. The screen will display menu options when correct password entered at last digit: 1. Alarm Settings 2. Calibrate 3. Configure 4. Information 5. Test 6. Exit Select Calibration. Screen will show calibration options: 1.
During 60 seconds you should apply necessary gas for zero level. For catalytic, pellistor and electrochemical sensors use clean air gas, for infrared sensors use N2 gas. For more details contact Prosense. Detector will automatically perform zero calibration while gas applied to sensor during this period.
Span period may vary depending of target gas. Span gas should be applied to sensor during span period. Detector will automatically set span level. When the countdown is complete, the detector exits the menu steps and returns measurment screen but stays in calibration mode. In this case, the value is read on the screen as gas is applied to the detector.
Fix front panel to enclosure body. Power On and check status. The main PCB module parameters recorded at Prosense factory. But if you see any deviation perform full parameter adjustment and calibration if necessary at least 4 hours later or nex day.
