2012 Wheeler Control_

2012/13 Wheelers Spreader Controls System The Maine Department of Transportation (MaineDOT) will be outfitting thirty five tandem axles for plowing during the 2012-2013 calendar years, with an option to outfit up to thirty- five more units in 2014-2015. MaineDOT is accepting bids, in compliance with the following specifications, for equipment to be purchased for this work.

Spreader Controls with Combination Display

1. The spreader controller: Cirus System preferred or approved equal, capable of operating a granular spreader with auger/conveyor, spinner, pre-wetting system, and a liquid anti-icing system with 3 booms, allowing individual boom selection in a single or dual tier arrangement. Each function shall operate individually or simultaneously without additional controller hardware.

2. Spreader control system shall be capable of ground speed orientated closed or open loop operation for all four channels (conveyor, spinner, pre-wet and direct liquid). Controller will be capable of spreading material through either linear spreading (i.e. gals and lbs/mi) or area spreading (gals and lbs/lane mile). The controller shall be capable of adjusting the application rate automatically and in correlation to measured road temperature, based upon user-defined thresholds when applying either, or both, granular and liquid materials. System shall provide a means for the operator to reset and/or indicate current volume of liquid in anti-ice and pre-wet tank(s) as part of power-up routine. System shall display current liquid volume in tank(s) while pre-wet and/or anti-ice system is active.

3. Spreader controller shall have a multi-line display that shall not washout in the daylight and remain clear and visible at night. Display – Material Control System shall incorporate a TFT color display screen with anti-reflective coating.

· Screen Size –minimum 4” x 7”

· Contrast Ratio – 200:1

· Viewing Angle – plus/minus forty-five degrees (+/- 45 degrees) horizontal, plus/minus thirty degrees (+/-30 degrees) vertical.

· Operating Temperatures – minus forty degrees (-40 degrees) to plus one-hundred eighty-five degrees (+185 degrees) Fahrenheit.

· Lighting- To insure longevity of performance, display lighting shall be solid-state LED technology. The use of incandescent lamps or EL backlighting is unacceptable.

· Adjustable Screen Illumination – Shall be capable of operator adjustable or system automatic adjustable for adjusting the brightness of the display screen contrast for day/night operating conditions.

The display shall be capable of simultaneously displaying granular, pre-wet and anti-ice application rates as well as air and pavement temperatures from a Road Watch pavement temperature sensor. The display shall also be capable of showing data from other sensors and controls, such as joystick functions for controlling hydraulics, GPS data, actual ground speed and all active alarms.

4. Spreader controller must provide “on-screen help” documentation of all main operating functions as well as on-screen diagnostics for system issues. On-screen help shall be sufficient to enable users to operate the system by following the on screen instructions, without referring to the printed operations manual.

5. System shall alarm either audibly or visually for the following conditions: off rate, sensor failure, low liquid remaining, low liquid flow shut off. Trouble shooting the entire system electronically and hydraulically shall be accomplished without the use of any tools.

6. System shall provide ten customizable application rates in each granular, anti-ice, and pre-wet materials. Controller must provide the ability to name each material. Rate increments shall be settable for each material.

7. The controller shall offer multiple layers of access control to set up files:

a) Factory-standard, password protected access to operating functions and setup files;

b) Supervisor re-set capability for each password;

c) Laptop computer access control for higher security.

8. The controller shall have a “Blast” feature that is capable of operating as: latched on, timed on or momentary on. Blast is active only while operator is activating Blast the switch/button and is disabled in the absence of a ground speed signal. The controller will default to the pause mode upon start up of the system to prevent spreading in the yard or shop.

9. Wiring Design: The system controller shall have one wire, from each hydraulic valve coil wired to a common ground point. The system must supply pulsed +12 volt power to the other lead for each individual valve coil with male Deutush connector. For safety reasons, grounding or cutting any wire at any point between any valve coil and the controller will be unacceptable. All connections outside the cab shall have a minimum IP69 connection.

10. The spreader controller shall be capable of collecting time, date and location stamped events for all operating modes, errors and alarms, and for all material dispensed. Also the system shall be capable of recording digital or analog data that comes from up to 4 sensors (such as granular hopper level, gate height opening, granular material flow, plow position, hydraulic pressure, etc). The spreader control system shall be capable of collecting and storing position data directly from a standard GPS antenna without additional hardware and shall collect and store temperature data from a Road Watch temperature sensor, at a minimum.

11. Data Collection: System must incorporate an Ethernet based platform and contain at least 512 megabytes of non-volatile memory on board and have capacity to store spreading data for a minimum of 100 days (twenty-four hundred continuous hours).

12. Spreader control system must be capable of automatically downloading data wirelessly to a base station computer. The wireless must conform to the industry Wi-Fi standard of 802.11(b) and (g) and must be off-the-shelf product purchasable in any computer parts store (i.e. Staples, Best Buy, etc…). Spreader control specific systems are not acceptable. The system must be capable of downloading data at a minimum of 1.5 mega bits per second (mbps). System must store downloaded data in an open format that is compatible with the standard data input format for GJS systems (“shape file format”).

13. Spreader control system must be able to output its data in a standard serial data stream format to any brand AVL system that is able to accept serial data.

14. All bidders must supply documentation verifying the use of this technology in the product supplied for this bid as being utilized successfully in the market for a period not less than 3 years.
