Operating Instructions
Page 19/60
_
The CCM system is always calibrated to the nominal pitch of a single chain size. The length tolerances of a
chain can mean that an initial elongation value of up to 0.15 % can be displayed when testing a new chain. This
value can even be a negative value!
_
The measurement resolution or accuracy of the measurement results is 0.1%.
_
Electrical parts should not be on the USB or IO-Link connecting cable.
_
Live parts should not be at the USB connector
_
The diagram below shows the preferred installation position for the product:
Other installation positions are not recommended.
4.1.2 Chain sizes
_
Standard-Baugrößenbereich der CCM-Systeme kompatibel mit Baugrößen:
BS chains: 08B to 32B; ANSI chains: 40 to 160
_
Each chain size requires a separate CCM system.
_
The system is delivered calibrated and ready for use for every chain size.
_
The system is supplied ready to use and calibrated to each chain size.
_
The CCM system always detects only one strand of the chain. This means that the CCM system is not
dependent on the design of the chain (simplex, duplex or triplex chains).
_
It is possible to measure roller chains with attachments on one or both sides. In this event, however, iwis
should carry out a technical feasibility analysis ([email protected]).
_
The CCM system cannot be used to measure leaf chains. To do this, you can use the iwis wear gauge .
5 SLE function
5.1 General description
The SLE function (Segment Link Elongation) can be used to determine the elongation level of individual segments.
This is particularly relevant for parallel running chains with or without attachments.
Using the SLE function, the complete chain can be broken down into individual segments - this increases the
information content about the chain condition, e.g. whether much more elongated segments are contained than the
average of the other segments.
In addition, this means that in case of maintenance, it is not necessary to replace the complete chain, but only
individual segments of it. In order to enable the SLE function or to index the chain, magnets must be attached to the
outer links (single chain) on both sides of the chain. (For double and triple chains, please consult iwis).
The SLE function only works correctly with chains that always move in the same direction; a reversal of the direction
of rotation (e.g. in lifting applications) is not compatible with the SLE function!
The SLE results can be retrieved via IO-Link as well as using the CCM-Monitor software.
5.2 Functionality
The SLE function requires an index on the chain. This index is made by magnets, which must be attached on both
sides to two opposite outer plates of a chain. The two magnets generate a magnetic field, which is detected by a
