Detector Configurations
This section describes detector connections and settings for PDM
communication. Detector Id(address) must be configured or known before
performing connection. Configuring detector IDs differs depending of the
detector series.
2.1.PQ Series
PQ series detectors don’t have switches for addressing. Address is
configurable via display for PQD series. For PQN series hand held terminal
(Purchased separately) could be used. Address is also configurable via PDM
software as described in this manual.
For configuring detector address, please enter the display menu. Default
password is “1234”. Go to 3.Configure -> 2.Modbus by pressing up down and menu
buttons. Set the Slave Address as desired. If address change is not needed
press and hold menu button to go back previous menu.
RS485 connection must be done to following ports.
Please visit www.prosense.com.tr/pq-
series for additional information about
PQ series detectors.
2.2.P Series
P series detectors are addressable via dip switches or PDM software. 5 dip
switches are used for addressing. Addressing via switches are limited from 1
to 31. If a different address will be used addressing must be done via PDM.
All 5 switches must be in off position for software addressing. 
Addressing via dip switches is binary. Please visit
www.prosense.com.tr/p-series for
additional information about PQ series detectors.
2.3.PC3 Series
PC3 series detectors are addressable via dip switches or PDM software. 5 dip
switches are used for addressing. Addressing via switches are limited from 1
to 31. If a different address will be used addressing must be done via PDM.
All 5 switches must be in off position for software addressing. 
Addressing via dip switches is binary. Please visit
www.prosense.com.tr/pc3-series for
additional information about PQ series detectors.
RS485 Port Configuration
A and B ports of detectors must be connected to RS485 converter. Please check
for a properly configured serial port via device manager. For usb to serial
converters suitable drivers must be installed.

many calibration licenses have been used. 5.9. Calibration Tab
This tab is used for calibration.
Zero Calibration: “Set Zero” button performs a zero calibration. Make sure clean air applied to detector and press “Set Zero”. After countdown finishes check if the zero value at “Display Mode” is updated.
Span Calibration: “Set Span” button performs a span calibration. Prior to span calibration please check “Detector Programming” tab for calibration gas information. “Calibration Gas” and “Calibration Gas Value” parameters must be entered correctly and saved before performing span calibration as all the cross multipliers for different gasses are recorded in database.
“Customer” and “Tube No” information are mandatory and must be filled.

5.10.1. Overview
Overview of “Detector Programming” tab is shown below. There are two save buttons and three configuration and information groups at this page.
Save Button 1: Saves “Sensor Settings” and “Alarm Settings” to sensor head. This information is recorded at sensor head so there is no need additional calibration process after sensor head is replaced.
Save Button 2: Saves “Base Settings” and “Status Currents” group to transmitter.
Some values are not valid for all types and series. Some values are just for information purposes and can not be changed.
If data entered are not valid, a warning pops up at saving process that indicates “illegal data”. For example, alarm 1/2/3 must be ascending values; if alarm 2 is lower than alarm 1 for a %LEL sensor this is not a valid configuration and tool provides a warning and data can not be uploaded.

Alarm Level : Alarm level configuration.
Auto Reset : Auto-reset setting. Open means when the alarm cleared alarm indication will disappear automatically, closed alarm information is latched and reset is needed to clear the alarm.
Relay : If coil of relay is normally energised or not.
When set to “Energised”, relay will change contacts when detectors power is off.
Trigger : Indicates if the alarm activates when the measured level is higher or lower then alarm value.
Closing Delay : Some applications may require to clear the alarm after a period of time, for example ventilation or exhaust fan controlling. Displays the delay time in minutes.

5.10.4. Status Currents
These are the current output settings. At example below detector produces 2.0mA output while at “Fault” status, 3.0mA for “Inhibit”, “Warm-Up” and “Calibration status”, 22.0mA at “Over Range” status and 4.0mA at “Zero” status.
5.10.5. Base Settings
Detector ID: Detector address setting. For all detector
series addressing via PDM tool is possible. For P and PC3 series addressing
switches must be in off position for software addressing.
Detector Serial No: Detector serial number information. Can not be changed.
Location: Location/Name Text/Company information. Maximum 24 characters.
Hour: Date and time information. Only PQ series stores date and time information. When base data saved, current local time of computer written to detector.
Test Warning Cancel: If ticked: Detector will not produce test due error upon exceeding the test period.
Battery Error Cancel: Only appliable in PQ series. PQ series includes a battery for internal logging and data recording and storing time information. Detector will produce a fault message if battery is not installed. If logging functions are not needed battery might not be installed. If ticked: Detector will not produce battery error if battery is missing or battery run out.
Zero Up to 3%: If ticked: Detector will not produce fault for %3 negative drift and will not display measurement until 3% of range is reached. For example, if this setting is ticked and you have a ppm sensor with 0-1000ppm range, there will be no measurement until gas concentration exceeds 30ppm.
Calibration Error Cancel: If ticked: Detector will not produce calibration due error upon exceeding the calibration period. Note that according to EN 60079:29-2 standard gas detectors should be calibrated periodically between 3 to 12 months.
Relay Error Cancel: SIL certified detectors (PQS series) will shut off if any problem to relay card occurs.
If ticked: Detector will continue to function normally if relay error occurs.
Analogue Out Flt Auto Reset: In case of any fault at analogue current output, for example short or open circuit, detector base will produce fault. If this setting ticked: After fault situation fixed analogue output fault message is cleared. If not ticket: Detector must be reset to clear the message.
Hart Modem Installed: Only appliable for PQS series detectors. Hart modem is optional and plugged in to base card. If hart modem is installed this setting must be ticked.
RS485 Error Cancel: Detectors will produce RS485 Error message when RS485 communication via panel, Scada or 3 rd party systems goes down. If this setting ticked: Detector will not produce RS485 error message.
Detector Language: Detector display language setting. Only appliable to PQD series of detectors.
Detector Model: Detector display setting. Only appliable to PQ series detectors. If PQD selected and display not installed detector will produce display fault message.

Hart Modem Settings
Single Drop Mode / Multi Drop Mode: HART communication mode selection. If single drop mode is selected analogue current output and HART communication is active. If multi drop mode is selected analogue output will be pulled to 4mA and only HART communication will be active. Multi drop mode means detectors are connected daisy chain and only communicates via serial HART communication.
Single drop mode means detector will modulate HART communication data over analogue output signal and both signals can be used simultaneously.
