HY-ALERTA™ 2600 Explosion Proof Area Hydrogen Monitor OPERATING MANUAL 2 DESCRIPTION 2.1 SYSTEM H2scan’s HY-ALERTA™ 2600 Explosion Proof Area Hydrogen Monitor provides hydrogen-specific leak detection and measurement for hydrogen concentrations as low as 4000ppm and can be scaled to any concentration up to 5% hydrogen by volume, a range representing 10% to 125% of hydrogen’s lower flammability limit. The system consists of two modules and a wireless remote control. The Sensor Module houses the hydrogen sensor and the Control Module houses the LCD display and I/O. 2.2 SENSOR MODULE The sensor module...

HY-ALERTA™ 2600 Explosion Proof Area Hydrogen Monitor OPERATING MANUAL WARNING: IT IS NOT THE INTENT OF THIS MANUAL TO SPECIFY MOUNTING LOCATION(S). IT IS THE RESPONSIBILITY OF THE USER AND INSTALLER TO DETERMINE THE PROPER LOCATION(S) FOR HYDROGEN DETECTION BASED UPON THE PARTICULAR USES OF HYDROGEN AT THE INSTALLATION SITE. 3.3 HYDROGEN SENSING CONSIDERATIONS From any given source, hydrogen gas disperses rapidly and generally upward due to the very low density of hydrogen compared to air. Understanding this behavior allows technicians to more effectively position the sensor to detect hydrogen...

HY-ALERTA™ 2600 Explosion Proof Area Hydrogen Monitor OPERATING MANUAL 3.6 MODULE WIRING The module connectors are of a two piece design in which the wires are screwed into a receptacle in standard terminal block style. The receptacle plugs into a header mounted on board. The Sensor Module connects with the Controller Module with a 16-pin cable. The wiring is point-topoint, so both ends have the same wiring. All wires must be sized to the amperage required. 3.7 SENSOR MODULE WIRING The Sensor Interface printed circuit board has a 16-pin terminal block, J1, for the Sensor Cable connection to the...

HY-ALERTA™ 2600 Explosion Proof Area Hydrogen Monitor OPERATING MANUAL 3.9 CONTROL MODULE WIRING The Power Board has a terminal block for the connection to input AC power. Some facilities have separate grounds for signal and AC power. If this is the case run the signal ground and chassis ground wires to the appropriate locations. If there is one ground, jumper the chassis ground and signal ground pins together in J2P. Do not connect the DC and AC grounds together if they are to be isolated from each other. Power Board: J2P 4-Pin Terminal Block for the Power Cable Pin Number Function Description...

HY-ALERTA™ 2600 Explosion Proof Area Hydrogen Monitor OPERATING MANUAL Normal atmospheric pressure fluctuations may also manifest as small hydrogen changes. At the factory, the units are typically calibrated at one atmosphere pressure. Performing the field calibration will compensate for altitude induced inaccuracy. 6 DISPLAY The upper row of the LCD indicates a numerical value for the percent hydrogen concentration or peak hydrogen value. The lower row of the LCD is used to display the hydrogen meter, a logarithmic bar graph ranging from 0.001% (10 ppm) to 100% hydrogen by volume. An open box...
