Installation of New Main Brush | Clarke SPS-28 guide

Installation of New Main Brush (cont)

Remove the three screws and washers and the bristle strip retained by them. Install the new strip and assemble the retaining screws and washers. Be sure to install the "V" of each strip in the same relation to the core as its companion strips. (See Fig. 11, page 11)

CAUTION: The strips must be carefully centered on the core before they are firmly lockedintoposition. Rotatethebroom by hand through a full revolution to check for possible interference with the shaft carriers at each end. Failure to check this area could result in damage to the drive mechanism.

Continue to replace one strip at a time, checking end clearance on each end, until all strips have been re- placed with new fillers.

Readjust the broom to allow for the new bristle strips.

The main brush is preadjusted at the factory to insure even engagement with the floor across its full width. However, should the brush show signs of uneven wear, end to end, compensating adjustments may be made. Raise or lower either end as required by changing the length of the adjusting rod. (See fig. 12)

SHOP EVALUATION OF CHARGERS (Qualified Service Personnel Only)

Service Hints

1.Check the AC power supply (plug, cords, building fuses and switched, etc.)

2.Check for physical damage.

3.If there is no DC output, check for blown internal fuse(s); blown fuses may be caused by reversed DC connections or by a defective diode.

4.Check parts - ammeter, timer-switch, diodes, trans- former and fuses for tight connections and for discoloration due to electrical failure.

WARNING: Always wear eye and face shield, and protective clothing when working with batteries to avoid injury.

5.Check the condition of the batteries.

a.Specific gravity (1.280 is ideal for fully charged batteries.

b.The battery bank voltage should come up to about 30.7 volts at the end of the cycle.

c.The DC charging current should start in the "normal" range and end in the "finish" range.

If the charger is still inoperative after the above checks have been made, call your nearest authorized service center.

Clarke® Model SPS-28 Space Sweeper Operator's Manual

SPS-28 specifications

The Clarke SPS-28 is a cutting-edge marine navigation system designed to enhance vessel safety, efficiency, and performance. This innovative system integrates advanced technologies to provide real-time data and analytics, improving situational awareness for operators in various maritime environments.

One of the standout features of the Clarke SPS-28 is its robust Global Navigation Satellite System (GNSS) integration. The SPS-28 uses multiple GNSS signals, ensuring high accuracy and reliability, even in challenging conditions. This multi-constellation support allows the system to maintain precise positioning for vessels navigating through busy ports or remote areas alike.

Another key aspect of the SPS-28 is its advanced radar capabilities. The microwave radar technology employed in the system allows for accurate object detection and tracking in all weather conditions. The radar’s long-range capabilities enable users to identify potential obstacles or vessel traffic well in advance, giving operators ample time to make informed navigational decisions.

The user interface of the SPS-28 is designed for simplicity and ease of use. Featuring a high-resolution touchscreen display, the system allows users to quickly access essential data, including navigational charts, AIS (Automatic Identification System) information, and vessel performance metrics. The intuitive graphical interface minimizes the operator’s workload by presenting critical information in a clear and concise manner.

Safety is a paramount consideration for the Clarke SPS-28. The system includes built-in safety features such as collision avoidance alerts and anchor watch functionalities. These features provide real-time alerts to prevent potential accidents, ensuring that vessels can navigate safely in congested waters or during challenging weather conditions.

In addition to navigation, the SPS-28 is equipped with several communication technologies, including VHF radio and satellite capabilities. This connectivity ensures that vessels remain in contact with other ships and shore-based operations, facilitating smooth coordination and response during emergencies.

Furthermore, the SPS-28 is designed with adaptability in mind, able to integrate with other onboard systems such as autopilot, engine management, and environmental monitoring tools. This integration enables a comprehensive approach to vessel management, streamlining operations and maximizing efficiency.

Overall, the Clarke SPS-28 represents a significant advancement in marine navigation technology, offering a suite of features that enhance safety, performance, and operational efficiency for modern seafaring vessels. With its state-of-the-art technologies and user-friendly design, it is an invaluable asset for mariners navigating the complexities of today’s maritime challenges.
