Overview
The 1010A is a powerful and intelligent loading system designed to manage the loading of petroleums and chemicals onto road tankers, rail cars and barges.
The 1010A offers the advantages of a robust explosionproof enclosure, large dot matrix display and alphanumeric keyboard. The 1010A can handle simultaneous loading on up to 4 arms.
The large backlit dot matrix LCD will display up to four separate totals as well as showing preset values, flowrates, operator prompts, and other operational information.
The 1010A also features an integrated Touch Key reader and an isolated RS485 communications port which eliminates the problems of earth loops and reduces electrical noise.
Applications
The Model 1010A is available with a range of Applications Packs, consisting of application software and hardware designed to meet the specific requirements of:
- Standard petroleum loading
- Loading aircraft refuelling trucks
- Railcar loading
- Chemical loading
- Bitumen & asphalt loading
- Chinese & other language displays
In addition, Contrec has developed a number of special Application Packs to meet the needs of customers in different countries or where non- standard requirements exist.
Communication protocols include the Contrec SLIP protocol for reliable and secure transmission of data, as well as an industry standard protocol (TOPS) which enables the two arm version of the 1010A to directly replace other electronic presets.

1010 A Load Computer – Standalone or Integrated System
The Model 1010A can operate in a stand-alone mode or integrate with a terminal automation system.
Standalone
In the Stand-Alone mode, the Model
1010A will provide complete control of the loading rack, including:
- Authorising drivers & vehicles
- Prompting the driver to enter arm number, compartment number and preset quantity
- Prompting and checking that the vehicle earth or overfill is connected
- Simultaneous loading of up to 4 arms
The Model 1010A will manage all loading operations for single or multi- compartment vehicles and produce a bill of lading for the entire vehicle.
The last 200 vehicle loads are always stored in memory, so that tickets can be re-printed or transactions downloaded to a computer system at a later date.
Integrated System
Because the system is capable of authorising vehicles and generating prompts without reference to the automation system, the communication workload on the office computer is substantially less than if these
functions were fully controlled by the automation system, as is the case with most other presets.
This means that the cost of developing software drivers and automation programs is greatly reduced.
The standard protocol used in the Model 1010A is SLIP, originally developed for the internet, because it provides a very reliable, secure and efficient method to transfer information to the office computer system. SLIP conforms to the International Standards Organisation OSI recommendations for multi-layered protocols.
Alternative Protocol
An alternative protocol to SLIP is an industry standard protocol, termed TOPS. The TOPS protocol is available for 2 arm versions of the 1010A and enables the system to directly replace other presets, in many applications.
With TOPS protocol much of the standalone functionality is lost as all messaging and control is passed across to the terminal automation computer system. Essentially, the 1010A
becomes a two channel batch controller when operated in this mode with the added capability of an operator display, keyboard and Touch Key reader – all controlled by the automation system.
Touch Key Technology
Touch Key technology offers a rugged and secure method of identification for both drivers and vehicles.
The Touch Keys produce a coded number, similar to a magnetic card, that can be read by the Model 1010A.
Unlike magnetic cards, however, the Touch Key numbers will not be corrupted through heavy use. Each key has a unique identification number
laser etched into a microchip that will transmit the number when the key is momentarily pressed against the reader.
Driver or vehicle authorisation can be granted by the Model 1010A via a database of valid key numbers stored internal to the system. Alternatively, the key number can be sent to the office automation computer for authorisation.

Touch Keys are available as a key ring tag in a number of colours or as a card, where the actual touch button is mounted on a plastic card or badge, of similar size to a magnetic card.
Standard Touch Keys do not have a battery and have an unlimited life span. The keys receive a very small amount of power from the reader, which is mounted on the front panel of the Model 1010A. An intrinsically safe isolation barrier inside the Model
1010A limits the power to microwatts, and both the keys and the reader are internationally certified for use in hazardous areas.
Functionality
The Model 1010A has all the flow measurement and control functions expected of a leading preset. These include:
- Precision flow measurement, including pulse verification to API and ISO standards.
- Temperature Measurement
- Volume Correction to API tables for most petroleum products and to US and metric standards.
- Digital Valve Control.
- Additive Control outputs
- Pump demand outputs with programmable delays.
- Permissive inputs for overfill, vehicle ground and emergency stop
- Pulse Outputs
- Other digital inputs/outputs specific to user requirements.
The digital control output enables the flow profile to be programmed to ramp up at the start of the load and to ramp down prior to the end of the load.
With our field proven fine-tuning algorithm, accurate control of flowrate is ensured for all major brands of digital control valves.
Modular Design
The modular design of the electronics simplifies servicing. Should a fault develop in the electronics, modules can be simply changed over in the field by technicians with minimal training.
The need for highly specialised personnel and/or costly maintenance contracts is eliminated providing terminals and depots with a level of self- sufficiency otherwise not available.

- European approvals to the OIML R117 standards with certification through NMI and PTB
