Introduction

The Prosense hand terminal is designed to help with maintenance and calibration operations on Prosense PQ, PX, P, and PC3 series detectors. The hand terminal uses MODBUS communication to connect the detectors. Prosense PQ, PX, P, and PC3 series detectors have onboard MODBUS communication circuits. The user should connect hand terminal MODBUS A and B ports to detector MODBUS and B ports. Communication ports must match each other for communication. The hand terminal operates with battery power and should be off to manage battery life.

Hand Terminal Menu

The hand terminal has 3 buttons on display that will be used to perform operations which are Enter, up (Increase) and down (decrease). To reach the configuration menu press Enter. The screen will request password information:

The password is 1234. Users need to change the password as defined in the “Change password” step. You need to set values by using the up and down keys. Once the value is set press Enter again to confirm and move to the next digit. Confirmed digits will be made invisible by the detector program:

The screen will display menu options when the correct password is entered at the last digit:

1. Alarm Settings
2. Calibrate
3. Configure
4. Information
5. Test
6. Exit

Menu structure

The PQ Series Detector menu includes all the necessary steps to set the detector and display information. The menu is available for only PQD and PQD-S models as they have display modules.

Alarm Settings

Alarm levels can be adjusted by using the alarm menu steps. The alarm menu’s general structure is given in diagram-12:

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. Alarm 1
2. Alarm 2
3. Alarm 3
4. Previous Menu

Please select the alarm level you would like to adjust and press Enter key to see details. All alarm details will be listed on the new screen and parameters will be blinking one by one while you set the values.

Alarm 1 Settings

• Level: 10%
• Auto-reset: NO
• Directions: Rising
• Relay: De-energized
• Off Delay: 00 Min

The first digit of the first alarm will start blinking to let you increase or decrease the digit by using the up and down keys. When you set the value, press again Enter key to move the next digit. The next digit will start blinking to allow you to set the desired value. When you complete, press the Enter key long enough. The display will show a “Successful” message and return to the higher-level menu.

All alarm levels have the same parameter that the user can adjust if needed. Otherwise, they will work with their default settings. The meaning of parameters is as follows:

• Level: The measurement level to raise the alarm
• Auto-reset: Define how the alarm relays will work. If ‘YES’ is selected the relay will be released once the measurement level returns to normal. If ‘NO’ is selected the relay will lock in their position. According to IEC EN 60079-29-1 highest level alarm ”Alarm-2” is set to latch mode without auto-reset.
• Directions: Parameter to define in which way the alarm will be activated whether increasing or decreasing. For most toxic and flammable gases it will be rising, for oxygen it can be both rising and falling.
• Relay: It defines the alarm relay working conditions. Relays can be programmed as Energised (NC) or Non-energized (NO) contact according to use cases and scenarios. When Energized is selected, the relay will have energy during normal operation. When Non-energized is selected, the relay is only energized when performing the switching function.
• Off Delay: The user can define a delay to deactivate the alarms. Equipment keeps alarms and relay contacts active after the measured gas level goes below the defined alarm level. This function must be adjusted according to operating conditions and safety rules. For example, in some plants ventilation fans are 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.

Once the test is completed screen will display back to the Test menu items.

Calibration

It is recommended to periodically carry out calibration to ensure correct operation. Prosense PQ series detector calibration includes two steps zero and span calibration. It is possible to perform each step independently. Prosense recommends performing both calibration steps for correct calibration. The detector should be powered and stabilized for at least 4 hours before calibration. During the calibration phases, the detector output is inhibited (default 3mA) to avoid false alarms. Zero calibration of infrared sensors should be done with N2 and zero calibration of other sensors should be done with zero air (O2 and N2 gas mixtures). It is possible to use calibration gas from 25%LEL to 75%LEL gas concentrations via adjusting reference gas details on the detector menu for calibrating flammable gas detectors It is necessary to use international tracable gases.

To calibrate the detector, use an appropriate span gas cylinder, constant flow regulator and Prosense Gas Cap. The gas flow rate must be 0,5lt/min for correct calibration.
It is recommended to use a compressed air cylinder (20.9%Vol oxygen) to perform the zero calibration if the area where the detector is located contains any residual amount of the target gas. If no residual gas is present then the background air can be used to perform the zero calibration.

To perform calibration select Calibration from the menu:

1. Alarm Settings
2. Calibrate
3. Configure
4. Information
5. Test
6. Exit

The screen will show calibration options:

1. Set Zero
2. Set Span
3. Cancel Cal
4. Reference Gas
5. Cal. Interval
6. Previous Menu

It would be better to first set reference gas details and calibration cycle period as these values cannot be altered once calibration started for zero or span. Zero or Span calibration can be performed separately at any time. It is recommended to perform Zero calibration first and perform Span calibration following zero calibration completion.

Set Reference Gas details
During calibration, technicians should use a certificated specific gas. The details of the gas should be entered before starting the calibration. Otherwise detector program will use default values entered at the factory. If the calibration gas is different than default gas specifications the calibration will fail or will be wrong. Select the fourth item ‘Reference Gas’ on the calibration menu to set details of the gas you will use during calibration. The default value is % 30 LEL will be displayed:

The first digit will start blinking on the screen. You can change the value of each digit with up and down keys. Once set, confirm the value with the Enter key and move to the next digit.

Set Calibration Cycle
Prosense recommends performing calibration over six months. Hence this default value is set to detector in factory. The detector will be faulted when the calibration period expires. If the user wants to use a different calibration period this should be set by using the option “Cal Cycle” on the calibration menu. Select “Cal Cycle” and press Enter. A new screen will display to allow you to set your calibration period:

The number will be blinking. Value can be adjusted using up and down keys. Once set press Enter key to confirm and return to the calibration menu.

Zero Calibration
Select the Set Zero option on the calibration menu and press Enter key to start zero calibration. The program will request a confirmation to start zero calibration:

When entered zero calibration will start and calibration time will be counted down:

Zero gas should be applied to the sensor for 60 seconds. For catalytic, pellistor and electrochemical sensors use clean air gas, for infrared sensors use N2 gas. For more details contact Prosense. The detector will automatically perform zero calibration while gas is applied to the sensor during this period.

Span Calibration
To perform Span calibration Select the Set Span option on the calibration menu and press the Enter key to start span calibration. At the same time prepare the span gas cylinder and regulator; mount the calibration adaptor to the sensor head and apply gas to the detector. The program will request a confirmation to start Span calibration:

After pressing the Enter key screen will again show a countdown for the span period. The Span period may vary depending on the target gas:

Span gas should be applied to the sensor during the span period. The detector will automatically set the span level. When the countdown is completed it will return to the monitoring screen by exiting from the menu. If you try to enter the menu detector will ask password again.

When the countdown is complete, the detector exits the menu steps and returns the measurement screen but stays in calibration mode. In this case, the value is read on the screen as gas is applied to the detector. However, the detector does not generate an alarm because the detector is in calibration mode. After the calibration is completed, the detector continues to operate in calibration mode until the amount of gas detected falls below the value defined for alarm 1 and the message “CALIBRATION” is displayed on the screen. When the amount of gas detected after the calibration falls below the alarm1 level, the detector switches to the normal operating mode from the calibration mode. The detector stays in calibration mode for up to 5 minutes and returns to normal operating mode. If the gas level does not decrease for 5 minutes after the calibration, the detector starts to generate an alarm.

Cancel Calibration
Calibration can be cancelled anytime during a calibration operation. If the user thinks something done wrong by mistake, should select the “Cancel Cal” option on the calibration menu. The detector will ask for confirmation to cancel:

Press the Enter key to cancel the calibration operation. The detector will erase the values recorded during calibration steps and use previously recorded calibration levels
