SCS3 Spreader Control System
Before SCS3
We relied on Relay Logic Spreaders
- a lot of connection points
- individual sensors & valves relays
- troubleshooting nightmare
** Did give you freedoms to bypass if necessary
Not too bad. We made it better!
- Modular Hardware
- Logic following SCS2 Success of FB
- Ability to Diagnose and assist in preventive maintenance
- User Friendly. If you can use a car stereo or GPS you should be ahead of the curve
* More Functionality out of the crane and spreader

* More Reliability

* Easy to use and mantain

* Demand for more information & statistics
Where are we headed with container handling???
With SCS2 Spreaders:
- Less connection points
- programming FB
- computer savvy
- Ability to log information
- Anybus compatible

Our Spreader and Communication Priorities
Expand System functionality: More tools for the users
Ease of Use: Information that is easy to access, understand and act upon.
Robust: Technology that will hold up well in the container handling environment.
With Relay logic...
It started as the beginning of efficient container handling. Manual lift spreaders became electro hydraulic units, ships cranes became second fiddle to the new ship to shore cranes. These spreaders were fitted with only a few relays for basic functions and a simple hydraulic unit that allowed the functions to be implemented.

But before we were able to run, we needed to learn to walk.
Before the technical advancements of spreader control systems, we were bound to using a control system based on contactors/relays/accumulators. It was the technology avaialable at the time.
Relay Logic cont...
- Control of basic functions of the spreader
- Safety interlocks non existent in most cases (trial and error)


Relay Spreaders
Individual Conductors for all Signals and commands
Relay Spreaders
Size of Baloney Cables restricted amount of conductors
Relay Spreaders
These restrictions along with the size and amount of connections forced Bromma to seek an alternative
The Programmable Logic Controller
It was our response to the requirements of the industry. First with SSCS and then SCS2.

With these necessities. SCS3 was born
By Bringing real time information to the technical staff we achieved:

- Decrease in spreader downtime
- Increase in reliability
- A platform that serves as a building block for newer advancements such as:
* SCS4
* Greenzone
* Loadsensing
SCS3 IS AN HMI that Illustrates
Communication status of buses
Spreader sensors and valves
Control Panel
Runtime and Spreader data
Settings and parameters
Configuration
Security - user levels
Language selection directly on the Spreader

SCS3 Generals
The SCS3 is fully capable to perform all functions that are given by the crane via serial or parallel communication.

Spreader Control
The SCS3 Mastercontroller's built in panel lets your perform all movements along with teaching positions/limits and synchronization.
The use of a laptop is still required when doing a program update or downloading a log of events for revision.
SCS3 Spreader control Layout
SCS3 Mastercontrollers have peripheral devices that complete the communication network and these are:
Can Open Devices:
CR9011
Crossfire MX3
Plank I/O board
Can Open Encoder (optional)
Pentium CPU
CE. Net
10.4" TFT
Resistive touchpanel
2 Can Ports
2 USB Ports
Ethernet 10/100
RS232 Port
Battery Backup 7 days
SCS3 Controller
Holds Program Logic
One per spreader
Interchangeable between units
Replaces SCS2 and Relay logic
CR9011 - Can Open Slave
8 digital/analgue inputs
8 digital outputs
individually fused ports
address set by potentiometer
Replaces Junction Boxes
Replaces distribution blocks
One cable for power and communication
Only used for controlling proportional valve Analogue input & SSI input from Absolute Encoder.
Crossfire MX3
Other ports are programmable but not used for bromma applications
All Inputs and Outputs come to these board via relays (commands and signals)

Can Open I/O Board
they control relays with 24vdc/120/230VAC
* Navigating the SCS3 requires some practice, but the key to it all is understanding that the user pages divide in:
Diagnostic Pages (Start)
Spreader Pages (Spreader)
SCS3 Controller:
User Pages
Includes the following subpages:
Spreader
Events
Alarm
Statistics
Messages
Trends
SCS3 User Pages
SCS3 User Pages
Events

Alarms
Spreader Control Pages
These Pages are divided in
TWL I/O
Tele I/O (Twin I/O)
Crane I/O
Panel
Settings
Misc
Spreader Control pages
Twistlock Pages
Twin I/O pages
Crane I/O - Inputs from crane & Outputs to crane.
Spreader control station
all functions enabled when logged in and spanner is "on"
Configuration pages - telescopic scaling and parameters
Teaching the Spreader
only done with abosolute encoder spreaders
before teaching make sure the telescopic chain is properly adjusted and the position markings are correct.
Troubleshooting an SCS3
In order to improve the reliability of the spreaders we have included some tools that will aid in the preventive and correcting maintenance, these are:
Start Page information
allows us first hand to see active alarms and status of communication networks
Scanning of the can open network
If our spreader network light is "red" this search function allows us to pinpoint the location of the damaged device
Crane I/O Page
We can see in real time whether a command comes from the crane or not, allowing us to determine if its a crane or spreader problem

SCS2
Ability to have an infinite number of inputs/outputs
Started as hardwire connections
Evolved to a Can Open communication network
SCS2 and its beginnings
SCS2 Network with individual relays for sensors, valves, commands and signas
SCS2 System with Can Open
Evolved from Hardwire to a two wire comm system
Timeline
How did we get here?
Can Open Internals
Addressing via Switch only, no programming needed
SCS3 Relay Boards
Dipswitches control the Address, data speed and mode (input/output)
