NOVAR 2100/2200 Operating Manual
These parameters can be set automatically using the AOR process. For manual setting, the
manual output type & power filler can be used too – see above.
If an output was detected as defective, it is marked with flashing decimal point of its number.
If an output was detected and marked as defective (for details see the output error alarm
description), this state can be cancelled and the output reincluded into power factor control
process by editing of its power or type.
4.3.4.4 Output Control State, No. 26
The output control
state parameter can be set to :
•
C
O
n
...(=control ) The output is used for power factor control process.
•
F
1
… (=fixed-on) After the controller being powered, the output, after preset discharge time
expires, is switched on and kept permanently closed. It is not used for the power factor
control process. The only case when such output is switched off is any of appropriate alarm
actuation activation.
•
F
0
… (=fixed-off) The output is permanently switched off, so it is not used for the power
factor control process.
During the AOR process or if circular or linear switching mode is set, the fixed outputs are taken as
non-existent and they are simply skipped.
Furthermore, the upper three outputs can be set to :
•
F
A
n
,
H
E
A
...(= fan, heater) The output is used for fan/heater control. Threshold
temperatures are specified in parameters 29 ÷ 31.
•
A
O
n
,
A
O
F
..(= alarm, active state on/off) The output is used for alarm signalling. For
detailed function description see appropriate chapter below.
4.3.4.5 Output Switch Count & Switch-On Time, No. 27, 28
These are not instrument setting parameters – statistics of outputs usage is displayed here :
•
parameter group
27
:
the output
switching operations
count since the last clearing. The
value is important for connected contactor lifetime estimation and is checked by
the NS>
alarm
. In case of the contactor replacement you can clear the counter by its editing and
selection the
C
L
r
option.
By checking frequency of switching you can tune other power factor control parameters
optimally during the compensation system commissioning.
The value is taken in account during power factor control intervention evaluation in order the
contactors to be loaded as uniformly as possible.
