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:

PRS-UM-HT-EN-Rev1.0-19.12.2022

Please select the alarm level you would like to adjust and press Enter key to see details. All

alarm details will be listed in new screen and parameters will be blinking one by one while you

set the values.

The first digit of the first alarm will start blinking to let you increase or decrease the digit via

The next digit will start blinking to allow you set desired value. When you complete, press

Enter key long enough. The display will show “Successful” message and return back to higher

level menu.

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.

Auto-reset: NO
