The Totally Automated Laboratory Model IQT™ (TALM-IQT™) is a system of kits that upgrade the current Lab Model IQT™ (LM-IQT™) to provide additional automation which increases the precision of results, and reduces operator intervention. Feedback from our IQT™ instrument user community was essential in devel-oping the TALM-IQT™; many of the TALM-IQT™’s features are based on your suggestions. The TALM-IQT™ system was designed to permit for a simple upgrade process of your existing LM-IQT™ both in the present and in the future.

To help you get the greatest value out of the TALM system, we have created three TALM kit packages that can make the LM-IQT ™ even more precise, increase the ease of calibration, or both. In order to upgrade the LM-IQT™ with TALM kits, it is necessary to first purchase TALM-K1 and TALM-K2: the System Control Cabinet, and the Revised Software Package respectively. Both of these kits are required to allow other components of the TALM system to interface with the existing LM-IQT™. The TALM-IQT™ builds upon the LM-IQT™’s industry leading precision and ease of operation, to

Key Benefits

AET has redesigned the IQT™ software's user interface to increase touchscreen support and more prominently display system and test status. Key operating parameters are easily visible along the side of the screen. Each parameter uses a colour code to display whether parameters are within limits. A prominent progress bar along the top of the screen allows the user to check test percentage completion at a glance.

Calibration of the IQT™ can be a somewhat labour intensive procedure. The automated calibration system results in a significant cost savings because the instrument will calibrate unattended. The automated calibration procedure is faster than the manual procedure, enhancing testing productivity and ease of use.

Prerequisites

• All existing IQT™s can be retrofitted with this kit.

• Installation is straight-forward and can be completed with only basic tools.

Installation

• Single step flushing and purging simplifies operating procedures reducing risk of possible operator error.

• Automated flushing and purging ensure that these procedureces are performed properly and consistantly.

• Reduces operator time and attention required.

• Significantly increases bleed valve durabil-ity.

Key Benefits

Feedback from IQT™ users has revealed that flushing and purging the IQT™’s fuel system is one of the most complicated aspects of operat-ing and IQT™. Flushing of the fuel system is required to remove any remnants of a previous test sample. Proper execution of the purging procedure is required in order to completely remove any air from the fuel injection system.

In order to simplify operation of the IQT™, AET has developed Automated Bleed Valve Control-lers. Two pneumatically-driven rotary actuators are used to gently open and close the IQT™’s existing bleed valves, completely under the control of the IQT™ System Software (ISS). When installed, the controllers allow the IQT™’s operator to perform the flushing and purging procedures automatically at the touch of a button.

• All existing IQT™s can be retrofitted with this kit.

• Installation is straight-forward and can be completed with only basic tools

Installation

• Access to rear of unit no longer required.• Operator warned immediately if the cool-

ant pump stops.• Tracking the coolant rate over time can

help predict possible pump failure and allow preemptive maintenance.

• Can save potentially costly repairs in the case of overheating.

Key Benefits

As part of the standard operating proce-dures for the IQT™, the operator is required to verify that the cooling system is working properly. To assist the operator, the IQT™’s cooling system is equipped with a rotary flow indicator, which allows the operator to verify that the coolant is actually circulating within the cooling system.

The IQT™’s flow indicator is normally mounted on the back of the instrument's wheeled cart, which can make it difficult to see it in some circumstances. The Electronic Coolant Flow Indicator allows the IQT™ System Software to display an on-screen reading of the coolant flow rate, as well as provide a visible warning if the coolant flow rate decreases below acceptable limits.

Prerequisites

• Wall mounted (mounting panel provided).• 5/8” open-end wrench required.

Installation

• Eliminates the requirement for the IQT™'s operator to periodically adjust the gas pressure regulators.

• Improves instrument precision by provid-ing precise and more stable gas pressures than can be achieved using mechanical gas pressure regulators.

• Warns the operator if one of the IQT™'s gas cylinders is almost empty, so that a test is not unexpectedly aborted.

Key Benefits

The Electronic Pressure Regulator Panel is controlled by an embedded micro-processor and incorporates a touch-screen interface which is used to control all aspects of system performance.

The Electronic Pressure Regulator Panel controls all three gas stream pressures and also monitors the supply of gas left in each of the cylinders. The operator is provided with notification before a gas cylinder reaches a critical volume so that a test is not aborted prematurely due to low system pressure.

Available sizes 55mlCompressed gas type Nitrogen, industrial Compressed gas supply pressure 50±5 psi (345±35 kPa) • Fume hood or well ventilated area located

within reasonable distance of the IQT™.• Compressed nitrogen gas supply plumbed

to ventilated area or fume hood.

Prerequisites

• No tools required for installation.• No modifications to the IQT™ are

required.

Installation

• Increases operator protection when dispensing potentially volatile fuels.

• Improves laboratory productivity by permitting multiple fuel samples to be prepared for testing ahead of time through use of multiple fuel reservoirs.

• Improves IQT™ cleanliness by moving most of the fuel handling procedures to a separate, well ventilated location.

Key Benefits

The fuel reservoirs currently used with the IQT™ must be filled when they are mounted on the IQT™'s fuel injection pump. This requires the IQT™'s operator to handle potentially volatile fuels such as heptane and MEH without the increased protection provided by a fume hood or well ventilated area. Fuel spillage on the LM-IQT™ would tend to remain until cleaned; which can allow operators to be unnecessarily exposed to fuel vapours.

The new self-sealing fuel reservoirs have a small ball check valve in the bottom of the reservoir and come with a cleaning/filling station. This allows them to be filled in a safe, fume hood or other ventilated area, and then transferred to the IQT™ for test-ing.

Prerequisites

• No special tools are required. The cabling merely plugs into the new TALM Control Cabinet (Kit #1).

Installation

• Avoids the safety concerns of any spills of waste diesel fuel or more volatile reference fuel material onto the laboratory floor.

• Is able to proactively remind the operator of a safety concern that is easy to forget.

• The waste container is vented so volatile vapours are not released into the labora-tory.

Key Benefits

With additional automation to the flushing and cleaning procedures, less time will be spent by operators around their IQT™s. Hence, there is a need to ensure the waste fuel container cannot overflow.

The new waste fuel container has a means of informing the IQT™ computer when it is becoming full and needs to be emptied. The operator is alerted via the graphical user interface that his waste fuel container must soon be emptied.
