Constraints
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
5
Controls
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.
