OK off voltage (see chapter
"14 Technical data")
Module-internal fuse
has tripped or other
module defect
13.2.2 LED display PQ modules and PSU-...-PS
connection units
malfunction possible cause
LED DIAG off Backplane
bus supply of
ET 200SP / SP HA
faulty
LED DIAG Module not ready
flashes green for operation (not
parameterized)
LED DIAG Module is param-
flashes red eterized, module
sends diagnostics
Type 8647
corrective action
Check the electrical
connection
Ensure correct load
voltage
Replace connection
unit (please contact
the Bürkert Service)
corrective action
Check operating voltage
of the interface module
Check correct
arrangement of
ET 200SP / SP HA
modules and valve block
Carry out valid
parameterization via the
configuration tool
Eliminate cause for
diagnostics
