1. Important notes
1.1 General note
New generations of common rail pumps with
injection pressures up to 180 MPa require an
adjustment of the CRS 845 test set. These
instructions show how to convert the CRS
845 test set for the required maximum test
pressure of 180 MPa. For this, the high-
pressure rail must be converted and the
new system software and firmware must be
installed or updated.
These instructions are a supplement to
the existing instructions for the EPS 815
and the KMA 802/822 electronic metering
system. These instructions are only valid in
conjunction with the existing instructions and
they must be kept and forwarded together
with them.
