Introduction
The Prosense hand terminal is designed to help maintenance and calibration operations on
Prosense PQ, PX, P, PC3 series detectors. The hand terminal uses MODBUS communication to
connect the detectors. Prosense PQ, PX, P, PC3 series detectors have onboard MODBUS
communication circuits. User should connect hand terminal MODBUS A and B ports to
detector MODBUS and B ports. Communication ports must match to each other for
communcation. Hand terminal operates with battery power and should be off to manage
battery life.
Hand Terminal Menu
Hand terminal has 3 buttons on display that will be used to perform operation which are
Enter, up (Increase) and down (decrease). To reach configuration menu press Enter. The
screen will request password information:
The password is 1234. User need to change the password as defined in “Change password”
step. You need to set values via using 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
detector program:
The screen will display menu options when correct password entered at last digit:

All alarm levels have same parameter that 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’ selected the relay will be released
once the measurement level returned to normal. If ‘NO’ selected the relay will lock in their
position. According to IEC EN 60079-29-1 highes level alarm ”Alarm-2” is set to latch mode
without auto-reset.
Directions: Parameter to define in which way alarm will be activated whether increasing or
decreasing. For most toxic and flammable gases it will be raising, for oxygen it can be both
raising 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: User can define delay to deactivate the alarms. Equipment keeps alarms and relay
contacts active fter 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 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.

Calibration
It is recommended to periodically carry out calibration to ensure correct operation. Prosense
PQ 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
for correct calibration. 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 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 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 technician 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 factory. If the calibration gas is different than default gas specifications the
calibration will fail or will be wrong. Select fourth item ‘Reference Gas’ on 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 screen. You can change the value of each digit with up and
down keys. Once set, confirm value with Enter key and move to the next digit.
Set Calibration Cycle
Prosense recommends performing calibration with six months period. Hence this default
value is set to detector in factory. Detector will be faulted when calibration period expire. If
user wants to use different calibration period this should be set via using the option “Cal
Cycle” on calibration menu. Select “Cal Cycle” and press Enter. A new screen will display to
allow you 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 back to calibration menu.

Zero Calibration
Select Set Zero option on calibration menu and press Enter key to start zero calibration.
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 sensor during 60 seconds. 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 Calibration
To perform Span calibration Select Set Span option on calibration menu and press Enter key to
start span calibration. At same time prepare the span gas cylinder and regulator; mount the
calibration adaptor to the sensor head and apply gas to the detector. Program will request a
confirmation to start Span calibration:

After pressing Enter key screen will again show countdown for span period. The Span period
may vary depends on target gas:
Span gas should be applied to sensor during span period. Detector will automatically set span
level. When countdown completed it will return to monitoring screen via exiting from menu. If
you try to enter menu detector will ask password again.
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. 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
alarm1 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 calibration operation. If user thinks something
done wrong by mistake, should select “Cancel Cal” option on calibration menu. Detector will
ask confirmation to cancel:
Press Enter key to cancel calibration operation. Detector will erase the values recorded during
calibration steps and uses previously recorded calibration levels
