Battery calibration
The battery health is continuously monitored during normal operation and is calibrated when the battery is fully charged. If for any reason the battery is fully depleted, the D1+ will lose the current stored battery calibration data.
Fully charging the D1+ will recalibrate the battery monitoring functionality

OPERATING MODES

The D1+ has 4 user-selectable operating modes for use in varying environments and reporting requirements.

Normal (default)
In-cab
Data log
Live data

Power management
‘Normal’ mode captures and records data at the speciﬁed logging interval, allowing the D1+ to provide real-time warnings and alarms on changing particulate levels.
‘Normal’ mode is intended for use when the D1+ device is used to monitor individual personal exposure to particulate levels within a working environment.
When conﬁgured to ‘Normal’ mode and connected via USB interfaces, the D1+ will power down its particulate sensor to allow for faster charging and data download.
This operating mode is indicated through the ﬂashing of the battery indication symbol during normal operation.
The use of the D1+ in ‘Normal’ mode allows for both real-time alerting and on- device data capture to take place simultaneously. The D1+ is designed to allow warning alarms to be set against a single Particulate Measurement (PM) value, however the device itself will log sensor data for the following sizes for offline review.

PM1.0
PM2.5
PM4.25
PM10.0

When recording PM readings to the internal memory, the D1+ will log the maximum value for each size at the speciﬁed logging interval.
In ‘Normal’ mode, the user selected alarm PM size readings are taken every second and used to update the applicable STEL and TWA calculations which are then checked against the conﬁgured alarm thresholds.

‘In-cab’ mode

The D1+ ‘In Cab’ mode allows for the same operating functionally as ‘Normal’ mode, however, it allows the particulate sensor and device warnings to remain active when connected or powered via USB interfaces which allows the device to be continuously used in a vehicle.
This mode is indicated via the solid illumination of the battery symbol during operation as highlighted.
The D1+ will turn itself off after 5 minutes after USB power has been removed to save power.

‘Data log’ mode

The D1+ ‘Data log’ mode follows the operational functionality of ‘Normal’ mode, but readings are not checked against alarm threshold levels and on-device warnings / alarms will not trigger.
This mode is intended for use during passive monitoring of environments where data is captured for download and post-analysis using the BreatheLITE software.
This mode is indicated via 2 turquoise illuminated icons as highlighted.

‘Live readout’ mode

The ‘Live readout’ mode allows the D1+ to stream live particulate data to the BreatheLITE software via USB connection.
Particulate data is also logged to the internal memory for download and analysis as required.
This mode is indicated by 2 violet illuminated icons as highlighted.

ALARM WARNINGS AND CALCULATIONS

The D1+ uses 2 LED icons alongside audio sequences to alert users to changing levels of airborne particulates as highlighted below.

If a threshold is breached during operation, the following alarm sequence is used to alert users to act based on the change in the working environment.

‘Icon 1’: Short-term exposure limit (STEL) alarm

The D1+ will ﬂash the amber STEL icon alongside an audible alarm (2 beeps per second). ‘Icon 2’: Long-term exposure limit / time-weighted average (TWA) alarm
The D1+ will ﬂash the red TWA icon alongside an audible alarm (3 beeps per second).
In the event that both alarms are triggered simultaneously, the TWA alarm will take priority.

Note : The D1+ is factory programmed with the following default STEL and long-term exposure limit / TWA alarm warning thresholds:

STEL alarm warning threshold – 1,000 µm/m³ over 15 minutes
TWA alarm warning threshold – 1,000 µm/m³ over 8 hours

The default threshold limits have been deﬁned based on a quarter of the permissible limit for most respirable dusts as outlined in the EH40/2005 guidelines.
Advice outlined in EH40/2005 states that where no speciﬁc short-term exposure limit is listed, a ﬁgure three times that of long-term exposure limit should be used. However, always refer to local guidelines and legislation to ensure that alarm warning thresholds are set at appropriate and permissible values for the intended operating environment.

Alarm calculations
The D1+ uses the following calculation for the monitoring of STEL threshold breach. STEL, where STEL TIME is in minutes: The D1+ uses the following calculation for the monitoring of long-term exposure reading/ TWA threshold breach.

TWA, where TWA TIME is in minutes:

Note : The TWA calculation will reset on device power cycle, the sum is calculated on device start up and initial sampling to the current run time and will accumulate until the device is switched off.

Alarm acknowledgement

In the event that a warning alarm is triggered, the D1+ will auto-latch to ensure that a conscious action is made to acknowledge the warning. During alarm state, users can acknowledge triggered alarms which will silence the audio alarm, however, the LED warning indication will remain illuminated (solid) to indicate the alarm conditions are still present.
It is only at the point of particulate level decrease to below the permissible threshold, 95% of the alarm set point, will the alarm reset and illuminated LED switch off.
To acknowledge a latched alarm, press, hold and release the power button after 2 seconds which will conﬁrm response via an LED sequence. (Scrolling Illumination of alarm colour, followed by a scrolling green sequence).

Note : If an alarm is not acknowledged by the user, the D1+ will remain latched with the illuminated LED and audio warning indeﬁnitely.
The D1+ device will only re-alarm on increasing or continued particulate levels above the permissible threshold after the original alarm has been user acknowledged and self-cleared.

CONNECTIVITY

The D1+ has been designed to be connected via the single USB port for battery charging, device conﬁguration, live operating modes, and data review purposes.

Charging

The D1+ device is charged via the on-device USB Port and cable provided. It is recommended that the D1+ is charged using a wall adapter where possible to ensure that the maximum power is delivered to the battery in the shortest timeframe.
The D1+ can be charged via a PC USB port, however, please note that this will take signiﬁcantly longer to charge due to standard PC USB power delivery limitations.
The following sequence is displayed on the D1+ during battery charging and is used to indicate the battery charge level. The D1+ charge sequence will run at differing speeds for fast (wall adapter) or slow (PC USB) charging.
The D1+ will display 2 solid white icons and a ﬂashing green battery indication once charging is complete. Note : When the D1+ is operated in ‘Live’ or ‘In-cab’ modes and consequently connected via USB during operation, the sequence highlighted above does not apply. These modes are designed to function during continued power of the D1+ unit via a USB or 12 to 24 V vehicle charger.

As part of the routine maintenance schedule and during use in high dust loaded environments, it is recommended that the D1+ sensor is cleaned from time to time following the steps below:

Wipe down the D1+ inlet surfaces with a damp cloth to remove any external dust and debris.
Using canned compressed clean air, spray the device inlet for 10 to 15 seconds to clean the dust path.

Cleaning labels
It is recommended to periodically clean the instrument with a damp cloth, to ensure the instrument user interface and keypad is clean and legible.

Particulate entry/exit apertures
The particulate exit aperture is protected by a stainless-steel grille to minimise the ingress
of ﬂora and fauna into the D1+ device. It is recommended that the grille is checked and cleaned during maintenance periods to ensure that it has not become clogged with ingress that may obscure the particulate sensing airﬂow.

Compliance audit check

The D1+ has been designed with an inbuilt compliance check routine / test to allow for the infrequent checking of device functionality against a selection of sized reference particulates.
The compliance check uses certiﬁed sample material that can be passed through the sensor to ensure that all sensing and sizing parameters are functioning as intended. Reference material with a speciﬁc size spread allows each sensing region to be populated with reference data during the process.
To run the compliance check sequence, connect the D1+ to the BreatheLITE software application, position in the supplied compliance base and cover with the particulate dispersion hood before selecting the automated test routine within the device maintenance menu.
The use of the compliance base and particulate dispersion hood allows for units to be isolated within a known volume during testing as highlighted below.
1. Insert the D1+ into the compliance dock.
2. Cover with particulate dispersion hood.
3. Run BreatheLITE compliance check.

The routine must be carried out using the Trolex Compliance Pack+ required to conduct the procedure, including:

Reference particle sizes (Reference material)
Dosing bottle

Sized reference material is used to periodically test speciﬁc operational aspects of the D1+ during the compliance audit check.
Once the D1+ is connected to the BreatheLITE software, and the compliance audit test has been selected from the maintenance menu follow the on-screen instructions to dose the device with reference particulate material.

Note: The dosing bottle is a dispersing mechanism for the sample particulate material. Please ensure that these components are kept in a clean and dry environment, free from moisture and contaminants.
It is important to ‘prime’ the dosing bottle by shaking it vigorously to ensure the reference material is free to disperse into the hood.
To dose the reference material into the particulate dispersion hood, use the built-in pumping mechanism several times to active dosing.

Compliance audit check: Results
BreatheLITE is designed to return a “Pass” / “Fail” result based on the compliance audit check results and operational threshold for the applicable particulate sizes. This is displayed on completion of the check and is detailed in the device log of each connected D1+.

Return of a “Pass” result
On return of a “Pass” result, the particulate sensor is functioning as expected and normal monitoring operation can resume.

Return of a “Fail” result

Run a sensor cleaning operation as highlighted in section 15.2.
Repeat the compliance audit check sequence and note the test result.
On return of a “Pass” result, the particulate sensor is functioning as expected and normal monitoring operation can resume.
On One unit return of a repeat “Fail” result, please contact Trolex direct to discuss support or servicing of the D1+.

Preventative maintenance
In some circumstances, a routine preventative maintenance schedule should be used to ensure that the performance of the device is upheld. The following table should be used as guidance to the level of unit maintenance required based on environmental dust loadings.

Dust loading| Average dust loading in mg/m3| Expected maintenance schedule
---|---|---
Low| Up to 5 mg/m3| 6 to 12 months
Medium| Up to 10 mg/m3| 3 to 6 months
High| 10 mg/m3 or above| 1 to 3 months

Note: Trolex understands all particulate types are different and therefore this matrix should be used as a continual maintenance guide only, operational environments may be different. It is recommended that an assessment of the site environmental and operating conditions is carried out from time to time to support the required frequency of a routine maintenance schedule.

Atomised particulate suppression and mist spray
It is recommended that the D1+ is operated with location and proximity consideration relating to atomising dust suppression systems. Instrument readings will include atomised or misted sizes that pass through the D1+ sensor, within the particle detection range.
