General Information
1.1 Target Group
This documentation is intended for technical service personnel.
1.2 Important Information for Use
Use The device may only be operated with the accessories supplied.
Clean the device with mild cleaning agents only.
Do not insert any objects which were not designed for this specific purpose into the
openings of the device, as this may lead to faults in the electronics.
When operating the device, always observe the general
accident prevention regulations.
Safety Do not operate the SSR within range of strong electromagnetic fields.
Please observe the temperature specifications!
Storage When not in use, the SSR device may only be stored according to the operating
specifications.
Installation During the installation of the device follow the directions of the manufacturers of
plugs and wire harnesses.
Shipping The device may only be shipped in its original packaging or in equally sturdy
packaging.
Use of unsuitable packaging constitutes negligence, whereby any repair under
warranty is forfeited.
Maintenance The SSR requires no maintenance throughout its entire service life and requires
no special care.
Opening the
SSR
The SSR contains no parts that can be maintained, replaced or repaired by the
customer or anyone other than authorised ehb maintenance staff.
1.3 Device Repair
Should a repair be necessary, please send the device to:
ehb electronics gmbh
Hans-Böckler-Str. 20
30851 Langenhagen, Germany
Please ensure that you enclose a written description of the fault(s). This will make it much easier for
the ehb electronics gmbh service department to find the error and return the SSR to you quickly.
Alternatively, use our online service for returning the device: www.ehbservice.de

NOTE!
ehb electronics gmbh shall only be liable for the professional execution of the work
it performs and for the correct quality of the materials used. Any further claims, such
as compensation for loss of profits and compensation for direct or indirect conse-
quential damages, e.g. loss of data, are excluded.
ATTENTION!
Damages due to improper packaging of the device for shipment and/or interference
by unauthorised persons will invalidate the warranty!
1.4 Product Disposal
Product
Please dispose of the product at the end of its service life in accordance with the applicable
statutory provisions.
Batteries
As the end user, you are legally obliged (pursuant to the German Battery Directive, BattV) to
return all used batteries after use. Batteries may not be disposed of in household waste!
Batteries that contain harmful substances are marked with the symbol shown, which indicates that it is
prohibited for them to be disposed of in household waste. The designations for the determining heavy
metals are:
Cd = cadmium,
Hg = mercury,
Pb = lead.
The relevant designation is marked on the battery, typically beneath the waste bin symbol shown
above. Used batteries can be returned free of charge to collection points provided by
your municipal authority and in outlets where batteries are sold.
In doing so, you are satisfying the legal requirements and contributing towards environmental
protection.
Thank you for observing these rules.

Component Description / Function
The SSR protects the starter, the pinion and the engine sprocket. It prevents accidental starting when
the engine is already running or when it is still shutting down.
The SSR is an electronic relay that is switched between terminal 30 and the starter (terminal 50f). The
engine speed is measured at terminal W of the alternator. The connections on terminals 15 and 31 are
for supplying power.
The D+ connection is required for some alternators for extra excitation. During the start operation, the
SSR switches on voltage to the D+ connection in parallel with the charging light. This ensures that
even at low speeds, the W terminal provides clear signals for speed detection.
2.1 The following conditions prevent the start-up process:
- There is already voltage present at input terminal W.
- After each start attempt, the ignition must be switched off for at least two seconds.
- After 6 seconds, a new start is possible.
2.2 The following conditions interrupt the start-up process:
- The frequency at terminal W exceeds a specified value.
2.3 Scope of Protection
- Start inhibited while the engine is running
- Start inhibited while the engine is shutting down
- Restart inhibitor
- Turning off the starter when exceeding the frequency (200 Hz) at terminal W.
- Start length is limited in time
2.4 Safety Concept
- The SSR is plus switching.
- All outputs are protected against overloading by short circuit detection.
- In case of overload, the current at the outputs is limited.
- The output transistors switch off in case of overtemperature.
- While the restart inhibitor is activated, the SSR does not require any power supply.
- For switching, the output transistors require a release from the processor and voltage
at input 50e (redundancy).
