About Your Monitor

The Aeroqual Series 300, 305, 500 and 505 Monitors have been specifically designed to incorporate Aeroqual’s in-depth knowledge of accurate ambient gas measurement. Different sensor heads are used for specific gases or depending upon whether high or low concentrations are to be measured. All the sensor heads are interchangeable on the same base unit.

The following information details the operation and features of the monitors:

1. The monitors are modular in design and are comprised of two main

components, a Series 300, 305, 500 or 505 monitor, and a sensor head. This affords the user the ability to replace faulty sensor heads without having to replace the monitor. The monitors can be mains and/or battery powered and either permanently mounted or used as portable units.

2. The sensor head is calibrated prior to delivery and does not normally

need to be re-calibrated during its life. (Specific user guides are supplied for the special operations of particular sensor heads).

3. The Aeroqual Series 300, 305, 500 and 505 Monitors come with onboard diagnostics, which will inform the user if the sensor is not operating correctly.

4. High and low alarms. The high alarm is indicated by flashing arrows pointing upwards accompanied by a fast beeping sound. Similarly the low alarm is indicated by flashing arrows pointing downwards accompanied by a slow beeping sound. This sets both the monitor and external alarms.

5. Alarm mute. Two alarm mute functions are available, temporary and permanent mute. Temporary mute is only active during the specific alarm condition, while permanent mute will remain on until reset by the user. The alarm arrow indications remain active during both temporary and permanent mute.

6. Control. This enables external equipment to be controlled by the monitor using the high and low control settings, which can be used to control an external device.

7. Concentration unit selection. The concentration can be displayed in either ppm or mg/m3.

8. Min / max / average measurement cycle. The monitor will display the minimum, maximum, average and 15-minute average gas concentrations over the measurement period. The Series 305 & 505 will also show temperature and relative humidity in addition to gas concentration.

.

7

.

9.

0-5V Analogue signal. A proportional voltage output is available from the external output.

The voltage relates to the gas concentration, with 0 V representing 0 concentration and 5 V representing the maximum concentration specified by the range. For example, 0 V represents 0 ppm and 5 V representing 0.500 ppm for the Low Concentration Ozone Sensor Head.

Note: See “Diagnostic Features” on page 42 for output status conditions.

The Series 500 & 505 Monitors offer the following additional features:

1.

Data logging (on either the Series 500 or 505 Monitor or directly to a PC). The monitor is able to log up to 8000 data points. The data can be downloaded to a PC for analysis and record purposes. Data can also be logged directly to a PC via a serial connection while displaying real time data on the PC. The data logging interval can be set in one minute increments from either the monitor or the PC.

The Series 505 monitor also measures and data logs temperature and relative humidity.

2.

Real time clock (24 hr). The clock has a back up clock battery which will maintain the real time even when all power is lost to the monitor. Once power is restored data logging will continue if the unit was data logging at the time power was lost.

3.

PC setup of monitor parameters. All the monitor parameters, i.e.

clock setup, alarm setup, external control setup, logging setup and concentration units can be set up from the PC.

.

.

Assembly, Wiring and Installation

Assembly

The following needs to be completed before the Monitor is ready for use: -

•

Insert the sensor head into the top of the monitor. The sensor head is keyed to ensure the head is inserted correctly.

•

If the monitor is a mains only unit it is ready for use. If the monitor is to be used as a portable unit with batteries then the batteries must be installed and charged prior to use.

Installing the Battery Pack

•

Remove the battery cover from the monitor.

•

Insert the battery power connector into the monitor power socket in the back of the monitor.

•

Lay the battery cable into the slot on the back of the monitor and insert the tail end of the battery pack into the hinge points at the bottom of the monitor back cover.

•

Clip the top end of the battery pack into the top clips, taking note to orientate the battery pack per the instructions on the battery pack.

•

Replace the battery cover on the monitor.

Notes on the battery pack

For more information on the correct use of the Ni-MH battery pack, please refer to ‘Battery Information’ on Page 43.

.

9

.

Rechargeable Batteries

The optional Ni-MH (Nickel Metal Hydride) battery pack is used to power the monitor as a portable unit. Please read the following information carefully before using the battery pack to operate the

Aeroqual monitor.

Safety

•

Do not use the battery pack for any other purpose than operating the Aeroqual monitor

•

Do not disassemble or mutilate the batteries as this may cause burns

•

Do not incinerate or heat as this may cause burns, the batteries may burst or cause the release of toxic materials

•

Do not short circuit as this may cause burns

•

Use only batteries approved by Aeroqual and recharge your battery only with the AC/DC adaptors supplied by Aeroqual.

•

Never use any charger or battery that is damaged or worn out.

•

Batteries must be recycled or disposed of properly. They must not be disposed of in municipal waste.

•

Never charge a Ni-MH in a hermitically sealed container.

Using the battery pack

The life of the battery pack will be affected by the way it is handled.

Take good care of the battery pack and follow the guidelines suggested in the following section.

.

10

.

Charging and Discharging the Batteries

•

NOTE: Battery charging occurs only when units (version 4.0

and above – as shown on the start-up screen) are switched on

or in standby mode. Older versions are not fitted with intelligent

charging and are best charged while switched off.

•

During charging the battery symbol on the display flashes slowly.

•

Battery can be charged with the sensor head installed or with the sensor head removed from the base. (Remember to switch off the monitor before removing the sensor head).

•

Intelligent Charging Circuit on version V5.1 will stop charging the unit when battery is either;

Fully charged @ 10.5V

Has been charging for 15 hours

The battery is unable to hold any further charge

(Unplugging the main power will reset the above charging conditions and charging will resume).

•

If battery is unable to hold the full charge (often sign of battery aging), then monitor will show RB on the battery symbol, indicating the battery may need to be replaced.

•

Unplugging the main power will reset the above charging conditions.

•

New Ni-MH batteries must be fully charged prior to use. A new Ni-

MH battery's full performance is achieved only after a number of complete charge and discharge cycles. A fully charged battery will run for approximately 7 hours.

(Note: Perc sensor heads require more power and will run for a shorter time)

•

The battery will normally charge in approximately 10 hours in

Standby mode, in 15 hours in normal operating mode and in a shorter period, if the battery was not fully discharged.

•

The batteries can be charged and discharged many times but will eventually wear out. When the operating time is noticeably shorter than normal, it is time to replace the batteries.

•

It is not necessary to fully discharge the batteries. When not using the Series 300, 305, 500 or 505 Monitor as a portable unit, always plug in the mains adaptor to recharge the batteries with the monitor

switched on.

•

If left unused a fully charged battery will discharge itself over time.

.

11

.

Removing the Battery Pack

•

Remove the battery cover from the monitor.

•

Insert your thumb under the top left hand side of the battery pack and carefully lever the battery pack out from the retaining clips.

•

Unclip the connector from the monitor.

•

Replace the battery cover.

Installing the AC/DC adaptor

•

Connect the AC/DC adaptor to the mains supply. Ensure that the adaptor is correctly rated for the power supply.

•

Plug the adaptor into the monitor. The monitor can now be used as a mains unit. If the monitor is to be used as a portable unit the batteries will need to be charged.

Warm up

Prior to operation the monitor must be warmed up to burn off contaminants on the sensor. When the monitor is first switched on it will warm up for 3 minutes. Then the reading will flash for the next 7 minutes to indicate that the sensor is still in the warm up phase. It is recommended that the monitor is kept in Stand By mode when not being used to keep the sensor heated and prevent the build up of contaminants. The monitor should be run for 24 hours on mains power prior to use if it has been switched off for more than 7 days.

Warning: Do not remove the sensor head while the

monitor is switched on.

This may damage the unit. If the sensor head is removed under these conditions, the unit will automatically shut down.

Monitor and Sensor Versions

Turning the monitor on will display “AEROQUAL MONITOR S300 /

S305 / S500 / S505 V x.x”, where "V x.x" represents the version of

the monitor base. The display will then show “

SV6.0

” or similar,

which indicates the software version installed on the sensor head.

Control

High alarm

Low alarm

Ground

The RJ12 connector offers two possibilities for wiring, either a switch to GND or a 12V output. If the 12V output is used, the power for the relay coil is supplied by the Aeroqual AC/DC adaptor. In this case, ensure that the relay coil does not draw more than 150mA and that a protection diode is inserted across the relay coil.

If the switch to GND output is used, ensure that the relay coil does not draw more that 150mA, that the voltage does not exceed 24V and that a protection diode is inserted across the relay coil.

Wiring for alarm

The high alarm and low alarm pins can be wired to supply simple on / off switching to operate equipment which requires only an on or off signal, such as an alarm.

To switch to GND use pins 4, 5 and 6. For a 12V output wire to pins 4, 5 and 1 (see diagram on page 12 for typical wiring for high alarm). This feature will only operate while powered by the AC adaptor. The factory default settings are based on the gas sensor head selected at time of purchase.

WARNING

Failure to insert a circuit protection diode, shown as above, will result in damage to the monitor if a voltage spike is created by the relay. (See Note: on page 46)

Wiring for control

The control pin can be wired to supply control of a gas concentration between upper and lower concentration limits. The upper and lower limits can be set by the user, thus affording the user the opportunity to customise the control. The factory default settings are dependent on the gas sensor head selected at time of purchase.

To switch to GND use pins 3 and 6. For a 12V output wire to pins 3 and 1 (see diagram on page 13 for typical wiring). This feature will only operate while powered by the AC adaptor.

Control is achieved by using a software latch. If power is lost to the monitor, the switch will open and therefore turn off the external device connected to the monitor external output. The following wiring diagram demonstrates the typical wiring to achieve the required control.
