5.10 ON/OFF Connection Identification
The control relay has an automatic
connection identification feature.
(Refer to section 2.1)
ON: The connection recognised by the
control relay can be read under mode
number -15- in accordance with Table 2.
(not changeable)
OFF: The connection must be manually
programmed as per Table 2.
5.11 Connection Mode
Usually, the connection mode should be
set to automatic operation. If, however, the
control relay failed to determine the con-
nection mode after 15 minutes due to high
load changes or phase imbalances, it is
possible to enter the connection mode
manually as per Table 2.
5.12 Setting Capacitor Discharge
Time
In order to ensure that after switching-off,
a capacitor stage is not switched on again
before the capacitor has been sufficiently
discharged, the switch-off time can be
adjusted to the specific needs (discharge
mode).
The discharge time can be set between 5
and 900 seconds.
5.13 Setting Cyclic/Non-Cyclic
Switching Rotation
In certain cases when there are filtered
and non-filtered stages within one system,
it is necessary to ensure that the control
relay does not operate cyclically. For such
applications this feature can be disabled.
On and off have the following meanings:
ON: Small number of switches, cyclic
switching is enabled on all levels.
OFF: No cyclic switching; the stages
within each level are switched on.
5.14 Setting Threshold for Number of
Switchings Alarm
In order to support the maintenance of the
unit the RM 9606 provides an internal
counter for each switching output.
During manual operation the present count
for each stage can be displayed.
(see section 6.2).
If the maximum of switching actions is
chosen the control relay displays the need
for maintenance. The stage which has
exceeded the limit (e.g. “ “ for the 4
th
stage) flashes on the display (approx.
every 10 seconds). At the same time an
alarm is signalised. How to put out the
alarm is explained in section 5.15.
