frako RM 9606 - Commissioning; First Commissioning Process

13
4. Commissioning
After the control relay has been installed
as described in section 3, the relay can be
put into operation.
4.1 First Commissioning
When the control relay is put into operation
for the first time it tries to determine the
mode of connection and the size of the
stages. The display shows "---" and after a
discharge time for the capacitors the
stages are switched on and off again one
after the other. This process can take up
to 15 minutes.
ATTENTION:
If the RM 9606 does not act as de-
scribed above, remove voltage source
and check installation.
If the identification process is not
concluded within 15 minutes there is
probably a fault. (See section 8, page 35)
Notice:
In order for the relay to be able to
determine the mode of connection at
least one capacitor stage must be
operational.
Possibly the control relay has already
been used before and acts as described in
section 4.2.
It is also possible to discontinue the identi-
fication process by switching off the auto-
matic connection and stage current identi-
fications. This takes place in set mode and
at the same time it is necessary to
programme the connection and stage
parameters manually (see section 5).
After the identification process the actual
power factor appears on the display and
the control relay begins to function.
If the power factor shown does not
coincide with the real power factor, the
identification process must be repeated.
This can be done by pressing the buttons
"+", "-" and "Set" simultaneously for at
least 8 seconds.
4.2 Renewed Commissioning
After a mains failure the control relay
immediately starts the normal control
programme again. The data which were
determined whilst being put into operation
for the first time are stored in a non-volatile
memory.
By pressing the buttons "+", "-" and "Set"
simultaneously for a least 8 seconds these
data are erased from the memory and the
control relay again begins to determine the
mode of connection and the size of
stages.
It is assumed that the automatic connec-
tion and stage current identification are
switched on (see section 5).
