4Constraints
The step has been designed to be functional and reliable. The product is made as simple and reliable
as possible. It has been taken in consideration that the step will be mounted under a vehicle in severe
environmental conditions
5Controls
5.1 Step Control
The step control is made as easy as possible. The controls comply with European 98/37 EC machine
directives. Functions and measurements are compliant with the R 107 UN Bus directive.
The electric step is an automatic system controlled by opening and closing of the vehicle door or
optionally by a driver operated switch.
5.2 Signals
The following output signals are available from the step electronics:
•Step out.
This is a red LED to make clear to the driver that the step is not in the stowed position and that he
cannot drive away safely. This signal will blink when the step is moving in or out
•Step in operation, moving in or out.
There is an audible signal when the step is moving in or out.
5.3 Legal requirement according R 107 UN Bus directive:
•Driver must have an indication that the step is fully stowed. It should be impossible to deploy the
step when a safety device fails. Manual operation is allowed.
•The horizontal movement of a step shall be interrupted when it is loaded with a mass of 15 kg.
•Extension of the step in the horizontal direction shall be protected by a safety device. In the event
of a safety devices coming into operation, the movement of the step shall immediately be stopped.
The Step On fulfils all these requirements.
5.4 Electrical Components
All electrical components in or outside the step cassette are water resistant to IP 65.
5.5 Power
12-volt commercial vehicle electrical system. Such a system consists of a 12-volt battery and an
alternator/generator system. The step performs all necessary functions when subjected to the normal
fluctuations encountered in a normally functioning 12V DC, commercial vehicle electrical system.
(optional 24 V system)
IMPORTANT Note: The ECU is not protected against changing the polarity at the power lead.
This will damage the ECU.
The power line needs to be protected by a 20 Amp fuse. This fuse is not included in the cable
loom.
5.6 Current control
The Step has a current control function. The step will stop with a load of max 150 N in front of the step.
It will retract and then try again to continue its movement out. It will try three times to move out, then it
will stay in the position where it was obstructed and fully returns when the door is closed or the driver
closes the step by a driver operated switch.
5.7 Motor
The motor specifications:
Voltage 12V DC (or 24V optional)
Unloaded rotation speed 70 rpm
Unloaded current 2 A

6Operation
6.1 Deploy Operation procedure
The step must have clearance from the vehicle. The vehicle
must have the parking brake on, and then the step can be
safely operated.
The electronics receive a signal from the door switch or driver
switch. If a door switch is installed the step will move out
automatically once the door is opened.
Time for either the full deploy / out or the full stow / in cycle is
approximately 2.5 seconds. When the step is moving the red
LED on the dashboard will flash until the step is completely out.
If the step encounters an obstacle it automatically stops. It will move backwards for a few centimeters
and then move forward again. If there is still an obstacle it will repeat this procedure three times, then
it will stop in the position where it encountered the obstacle.
6.2 Stow operation procedure
To stow the step the door should be closed or the driver has to give a signal that the step should stow.
The same rules apply as for moving out.
At closing a signal from the close switch will indicate that the Step is completely closed. This close
signal will also give the vehicle the OK that it is safe to drive the vehicle away, the Red LED light at the
dashboard will go off. If the step is not stowed properly the RED LED keeps blinking.
Step moving = Blinking LED
Step out = Shining LED
Step in = LED off

7Manual Operation
In case the step fails, it is possible to operate the
step by hand. This is done by the following
procedure:
1. Put a large screw-driver through the
long hole in the bottom cover in the slot in the
motor base plate.
2. Twist the screwdriver counterclockwise.
This will unlock the driving mechanism. Now the
step can be moved in or out by hand.
3. After moving the step in or out return the
screw-driver in the slot to re-lock the step in the
in or out position.
8 Mounting / Installation
The installation can only be done by a company that is well known with bodybuilding or modifying
vehicles, which has the trained technical staff to do this job.
8.1 Mechanical Installation
For mounting the step you do not need to make any large vehicle adaptations. The step is placed under
the floor in the middle of the front, middle or rear door.
Chassis modifications are not needed.
Warning: Changing the vehicle chassis affects the strength of the vehicle. This kind of changes
is only allowed after approval of the vehicle builder / constructor. You need to consult the vehicle
builder for these kinds of changes. Acdeos cannot be made responsible or held accountable for
any vehicle / chassis changes.
Exact measurements of the product should be taken from the official installation drawings. Ask Acdeos
for the last revision and official installation drawing. Figures, drawings in this manual are only for
indication.
Installation:
Create a safe working condition. Lift the vehicle to the appropriate working height.
Define the place where you want to mount the step under the vehicle. Make sure the cassette can be
mounted on the required position without colliding with the chassis or other vehicle parts. Make sure
that the step is not to close to hot parts like the exhaust system. This can damage the step.
The picture below gives the basic principles for mounting the step.
Define the place for the 4 mounting bolts on the front. The holes for this fixation should be drilled in the
lower flange of the outer chassis bar of the vehicle. Drill the holes ø6.5 mm. Always protect all drilled
holes with zinc spray. Make sure there is enough material in the flange under the hole. Place the step
with two bolts at the flange and support it at the rear.

Always try to go as vertically as possible straight up from
the fixing point on the rear of the step to the fixing points
on the vehicles floor.
The M8 studs should be placed as vertical as possible
You can adjust the height of the step
under the vehicle by adjusting the front
brackets in the slot holes.
Take the flexible mounting brackets supplied with the step.
These brackets can be mounted in several ways. The brackets
should be used to fix the rear side of the step to the bottom of
the vehicle. It is recommended to find a strong point at the
vehicle floor. Mount the brackets in such a way that they bridge
the gap between step and vehicle floor / chassis.
This fixing requires some technical knowledge and own
interpretation.
Adjust the step to be horizontal under the vehicle.
Finally fit all bolts and nuts to mount the step completely.
When the possibility of attachement on the
back of the step is too far back, or there is a
fuel tank or something similar in the way, it is
possible to use a piece of L bar to extend the
back point of attachment.
In the case the flange of the
chassis is too far back, it is
possible to flip the brackets as to
place the step further forward.

8.2 Electrical Installation
Find a good route for the cable to the front of the
vehicle or to the area where it will be connected to
the vehicles electrical system. The principal idea for
the routing of the cable loom is as follows: cable
should run under the vehicle to a place where you
can enter the vehicle. Try to find a dry place for the
4 pin connector in the cable loom inside the vehicle
to battery or power point and dashboard for
dashboard light. The cable to the door switch should
run directly to the door-pillar where the door switch
is mounted. Please refer to the electrical diagrams in
the rear of the manual appendix I.
There are two possible operations of the
step.
1 - Door switch. Steps moves out
automatically when the door opens
2 - Driver operated switch on the
dashboard where the driver operates the
step. In this case, it is still recommended
that the door switch in installed. Without
the door switch the driver could forget to
close the step when the door is closed,
and drive away with an open step.
Connect the green wire at the handbrake
switch or other signal indicating that the
vehicle is stationary. You need a signal
when the vehicle is stationary. The
handbrake switch is not supplied with the
step.
For safety reasons we recommend this
signal is used.
If you decide not to use this
signal Acdeos cannot
take any responsibility
for any unsafe
operation of the step.
Cable colours:
black Ground
Red Power (Use a 20 Amp fuse)
Green Ground signal for operating
the step

•Close the door. Measure the gap between the door and the door post. Adjust the
switch so, when installed, there is 7 mm of space between the switch and the
door or 3 mm between switch and magnet.
•Push the switch + plastic holder in the drilled hole and fix / seal with a bit of PU glue.
•Place the magnet on the opposite position on the door. Fix the magnet with a screw.
12.5
mm
Lead the cable with the door sensor through the
doorpost and stick the switch through the 12.5 mm hole
Place the Switch in the plastic holder. This is a tight fit.
You need to screw the holder around the switch.
Mechanical Installation of door switch:
Find the right place on the door to install the
door switch, preferably around the area in the
doorpost where you find the original door
switch. Make sure there is minimum around
10-12 mm free space between the door and
the door post when the door is closed.
Drill a hole of 12.5 mm at the selected place.
The door switch is supplied as standard with
the cable loom.
Check that magnet does not touch the switch
when door is closed with high speed and force
(slammed)
Careful, the Magnet is brittle. First drill the hole
and then fix the magnet with the screw just tight
enough to fix it. Fixing it too hard will damage
the magnet.

•When installing the switch using the nuts, the switch
must stick out at least 12 mm because of the need for
magnetic flow around the switch.
•The distance between the end of the switch and the
door should still be 7 mm.
IMPORTANT: Max torque to fit the switch is 5 Nm (This is light hand tight) If
you use higher torque, the switch will break / crack, which will lead to unreliable
door signals.
•Place the red LED in the dashboard in the direct view of the driver. Connect the free wire to 12 V
power. The LED lights up red when the step is out and flashes when the step is moving in or out.
•Connect the black wire to ground.
•Connect the red wire to 12V power. You need to add a fuse of 20 Amp between
the battery and the power cable. Decide whether to connect the step to constant
power or to power behind the main switch. We recommend placing the step behind
the main switch. The step ECU has a sleep mode using less than 1 mAmp in standby
mode
•Connect the cable loom to the step with the connector. Place this connector
preferably inside the vehicle in a dry area.
•The step is now ready for operation.
If you decide to use driver operation, place a
switch on the dashboard and connect it to the
Green wire. Closed signal => step out. Open signal
=> step stowed. To prevent oversight from the
driver’s point, also install the door switch to prevent
driving with the step in outward position.
