Installation instructions
1 Application and Function
ThestepcontrolEMS03-4isusedtocontrolelectricmotorsusedinstep
controls. The use of the step control EMS 03-4 requires very little current for
the operating buttons and the control leads. This means that thin cables and
standard button types can be used. It is possible to switch several buttons in
parallel. This allows operating in various parts of the vehicle.
The step control has the following:
FButton-control
FCurrent monitoring
FTime control
At least one button with changer function and middle setting ”0” must be
connected to the step control and the battery voltage must also be connec-
ted.
The step control controls the motor in the following way:
FDriving the step control in an out by briefly tipping pressing the button
at the entrance; the motor is switched off when the step control re-
aches the stop.
FThe motor stops if the step control meets an obstacle, is jammed or
frozen.
FThe control can be accessed via an (optional) second switch at the
driver’s seat.
YDANGER!
Operating the step control without seeing it!
Risk of injury:
FEnsure that when operating the step control (e.g. from the driver’s
seat) nobody is near the operated step control.
"Briefly activate the button in the ”drive out” setting.
FStep control moves out.
"Briefly activate the button in the ”drive in” setting.
FStep control moves in.

3 Mechanical installation
Das Gerät ist für die Wandmontage mit den An-
schlüssen nach unten oder Bodenmontage vorge-
sehen.The device is designed for wall mounting
with the connections facing down or for floor
mounting.
"Install in a dry area.
"Ensure that there is a minimum clearance to
the surrounding equipment:
FEnsure that there is at least 1 cm clearance
on all sides -- except the mounting side.
FDuring operation the surrounding tempera-
ture should not exceed +70 C (measured at
2.5 cm clearance to the sides of the device).
"Screw the step control with two screws (screw
diameter 6 mm) in the designated drill holes.

YWARNING!
Protection against reverse polarity
Damaging the electrical equipment of the basic vehicle:
FEnsure that the necessary voltage levels for the control voltages cor-
respond with the necessary values.
FOnly make connections if the system is not connected to a power sup-
ply.
YATTENTION!
Short circuits
Damage to the step control or cable burn:
FTo protect the wire transmissions, insert fuses directly at the battery
plus pole.
Select cable thickness 1 or 2 in accordance with EN 1648. The maximum
current must not exceed 90% of the safety value.
Connect the step control in the following sequence (also see the block dia-
gram:
1. All connections to the buttons
2. Motor
3. Battery voltage
Disconnect in the reverse order.
YIndividual blade receptacles AMP 6.3 can be used for the connection. Al-
ternatively, suitable wire harness can be used for ST1 and ST2.
