SISCP01a ELECTRONIC CONTROLLER (POSITIVE WIRED +) from SLOT.it
|
|
The SCP-1 is contactless, friction free, with linear magnetic trigger position readout and features an interchangeable module system, to connect to either Analoge (+) or Analogue (-) or Digital systems.
At this stage the SPC-1 is supplied for use only with (+) Positive Wired Analoge Tack Systems. Most commercial and club tracks are positively wired.
Home circuits like Scalextric Ninco Carrera etc are negatively wired hence you will need to replace the analoge plug in (+) module with the 'Negative (-) Analoge Module'
These additional modules will become available 4th quarter 2008.
The Digital Module is universal for all the available commercial brands (Ninco, Carrera, Hornby Scalextric and Tecnitoys SCX.) For the Davic system, the list of components and PCB layout for a compatible digital cartridge will be made publicly available |

SCP-1 CONTROL DESCRIPTION
|
 |
POWER TRIM (PT) also known as 'anti spin', this knob controls how the power trim strategy
delivers the power to the car.
The PT knob sets the maximum accepted 'slope' for a power increase: if the power increase ratio is above this slope, the 'power trim' slope is applied instead. In other words: if the trigger is pulled sharply, the power increase ratio is very high: in this case, the power trim strategy releases the power to the car through a more gentle slope. In reality, a 'real' anti spin should monitor the wheel speed and detect wheel spin before cutting back the power. This is not what this controller does, which is, instead, a 'smoothing out' of the trigger action.
Actually, this idea is rooted in what was legal in the F1 rules in the 90s: real closed loop anti spin being banned, this was as close as one could legally get
PT for digital systems:
there is no difference between the analog and digital controller as far as the PT is concerned
CURVE/MAX (CM) the core of the SCP-1 inner workings, Depending on the chosen working mode , “linear”, “linear with speed limit”, “curve”, it has two completely different functions.
“linear”, and “linear with speed limit” modes: if you have not read the explanation on these two modes, then now it's probably time to read the relevant chapter. If you have, then this knob sets the maximum speed in both cases.
“curve”: if you have not read the explanation on this mode, again you should do so now, or proceed at your own risk.... If you have, this knob, in this case, moves the working point on the 'X' axis and, together with the Dip Switch setting, which works on the 'Y' axis, sets the third point through which the curve is set, the other two points being the minimum selected by the MS knob, and the 100% fixed maximum.
CM for digital systems:
there is no difference between the analog and digital controller as far as the PT is concerned
MIN SPEED (MS) This knob sets the starting speed of the slot car ie the mini um voltage which is applied to the track, when the trigger is pulled just enough to leave the 'braking' area. Also known as sensitivity, in terms of a traditional resistor based controller, it is similar to changing the resistor's value, to get a faster or slower start point.
MS for digital systems: there is no difference between the analog and digital controller as far as the PT is concerned
BRAKING BK braking occurs when the trigger is completely released. The braking knob selects between two different braking strategies: 'sweep' and 'fixed'. The braking dial is split in two halves: one, under the label 'sweep', puts the braking system in 'sweep' mode, the other half, under the label 'fixed', does the same but for the 'fixed', standard, mode.
The 'fixed' mode, clockwise, is the 'standard' mode of most, if not all, other controllers with adjustable braking: depending on the dial position, you get a stronger or weaker braking according to the knob setting.
HAND BRAKE ( ANALOG & DIGITAL MODE)
The round push button marked 'Hand Brake' is an instant brake, thumb activated. While pressed, power is cut and braking performed according to the BK knob setting
BK for digital systems:
Hornby SSD: braking can in fact be adjusted with the BK knob as you would on an analog system.
Only, the possible settings are 100%, 80%, 60%, 40%, and 20%.
Ninco N-Digital: either brake 100%, or no brake.
Tecnitoys SDS: no braking is provided by Tecnitoys on their system, so there's no braking available
with the SCP-1, either.
Carrera: always 100% brake when available from the track (preliminary).

SCP-1 TRACK CONNECTION
|
The colour scheme of the SCP-1 cables follows the standard US (Parma) colour coding. WHITE is +, RED is – (ground), BLACK is motor (track). If you have a DS connection box, colour will match the existing colours on the female plugs of the box. Anyway: plug the WHITE/YELLOW cable into the POSITIVE (+) terminal of your track; plug the RED cable into the NEGATIVE (-) terminal of your track; plug the BLACK terminal to the motor connector of your track
Two devices protect the SCP-1 against polarity inversion, which happens if the cables are mismatched. This should not happen often, but it can happen, so the SCP-1 is shielded by 1. Fast Fuse, 2.5A, replaceable. In the table below, this protection is referred as FF
2. Resettable Fuse (Automatic). In the table below, this protection is referred as RF |
 |
PROTECTION AGAINST SHORT CIRCUITS BETWEEN RAILS
|
This is the most common situation in normal use. A screwdriver on the track, a screw across the slot, a copper filament crossing the braids are normal events that any controller should handle gracefully. The power MOSFETS used in the SCP-1 are of high quality and specifications, however this alone is not enough to guarantee a happy and healthy life to your controller. So, the Slot.it SCP-1 continuously monitors the current drain from the track and cuts power if the current is higher than 6 amps. The situation is checked every few tenths of a millisecond, and if the short circuit goes away, power is restored. The 'diagnostic' LED flashes with one flash every two seconds while this condition is detected. This obviously means that with the 'standard' analog cartridge, motors with a very large current drain cannot be used. This excludes the motors commonly used for 'metal slot racing' (group 16, 20 27 & open) but includes all motors commonly used in plastic cars.
An 'unlimited' cartridge, is planned, for higher current requirements ie group 16, 20 27 and open class |
PROTECTION AGAINST SHORT CIRCUITS TO GROUND
|
This is quite unlikely during normal use, but can be caused by a mismatch between Motor and
Ground cables.
The 'diagnostic' LED flashes with two flashes every two seconds, while this condition is detected. |

UNDERSTANDING HOW THE SCP-1 ELECTRONIC CONTROLLER WORKS
|
The Slot.it SCP-1 is a sophisticated, microcontroller based, speed controller for slot cars. It has a PWM output for both power and brake, plus a lot of other features. Without entering too much into detail, PWM (Pulse Width Modulation) is one of the possible ways to control the output voltage of an electronic system. A PWM system basically 'chops' the output voltage in a series of on-off periods, whose on-off ratio corresponds to the desired voltage according to the formula V=on-off ratio * track voltage. In other words, if you have a track voltage of 12V, and an on-off ratio of 1/4, you are feeding your car 1/4*12 = 3V, and so on.
|
The ratio is chosen by the microcontroller, according to the trigger position and to the desired responce curve.
The SCP-1 has basically three, very different operating modes, plus a 'ghost' (automatic) mode:
1. LINEAR with step (mode 1): the relationship between the trigger and the voltage output is a straight line. The controller, when the trigger is fully pressed, will always provide 100% power. Due to its innovative and in our opinion clever, strategy, this mode has a lot of flexibility and can help in the most difficult situations.
2. LINEAR with max speed limiter (mode 2): the relationship between the
trigger and the voltage output is a straight line, but when the trigger is fully
pressed, optionally, the voltage can be reduced down to a selectable minimum
of 60% of the available voltage. This is extremely useful, for example, for children.
3. CURVE mode (mode 3): a very sophisticated mode with full control of the response curve, where the relationship between the trigger and the voltage
output is not a straight line, but can be made convex or concave more or less at will. There is also a further useful mode:
4. GHOST mode (mode 4): a self-run mode with adjustable speed, useful
for running a ghost car on the circuit (or more, if more digital cars are
programmed with the same ID), or running in a motor.

2100 CIRCUIT MASTER controller
POSITIVE POLARITY incorporates features that a lot of manufactures leave out, or are only available as add on.
HO, 1/32 & 1/24 16d, Super 16d, Group 12, Group 15, Group 20
1. Adjustable Brakes
2. Adjustable Sensitivity
3. Full power relay
4. Replaceable resistor
5. Very light weight handles
6. Aluminium heat sink
7. Rubber feet on the heat sink
8. Easy to clean wiper band area
9. Built on Parma turbo qualifier base.
The 2100 CIRCUIT MASTER Controller has combined the best features that an electronic controller’s can have. Light and more comfortable due to the bulky and heavier components being relocated at the end of the controller lead with the power transistor, heat sink and relay. This makes it more comfortable and easier to manage during a race. This also means when FULL POWER is required, by having the power transistor and relay at the plug end, the cable lengths are the shortest possible, hence minimising VOLTAGE DROP giving you the Maximum Power Possible. |

1. Brake Pot
When the brake dial is turned to “FULL BRAKES”, this is like having a regular controller without a brake adjustment. Giving the car its maximum r dynamic braking (this only applies where a braking system is already installed on the track). As you turn the dial, the brakes become softer, and allows you to brake a little earlier and enter the corner a little quicker, and not have to pull the car up suddenly before the corner. (A brake switch is not an effective alternative as full brakes and no brakes are your only options. Thus, you’ll either pull up to screeching halt, or glide into a corner with too much speed. This inevitably wastes time and/or results in de-slotting.) All slot cars have different braking potential. And it’s a proven fact, that a brake control will help racers, tune their cars to suit the track and their own braking style, and thus improve on overall lap times
2. The Sensitivity Pot
The sensitivity control allows the racer to adjust the bottom end speed to suit the car and track design for any slot car from a home set brand like Ninco or Scalextric up to a Group 20. This is equivalent to changing the overall resistance of the controller to match the car you’re racing without having to change controllers. So during a race you can re-adjust the sensitivity pot to suit the new lane you’re on. To enhance further the flexibility of the CIRCUIT MASTER Controller a pair of interchangeable network resistors (no soldering requires) allows you to further customise your circuit master to the scale and class of racing, from HO all the way to 1:24 Group 20

The semiconductors also are polarity sensitive. They conduct electricity in one direction, but block it in the other. This feature has some advantages and also some disadvantages. The advantage can come from a natural resistance to miswiring since the semiconductors will block the flow of electricity if proper polarity is not applied. The disadvantage of this polarity sensitivity that the controller can not immediately be used with negative polarity track wiring |
