NOVAR 2600 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 below.
If an output was detected and marked as defective (for details see the output error alarm
description),after being edited this assignment is cancelled and the output is reincluded into
power factor control process by editing any of the two parameters.
The output reactive power is specified as a single number representing total three-phase reactive
power in (usually ) kvars. For standard output types you can simply edit this one number only.
For general impedance output type Z ( ) you can edit all of the output phase power vector
components – three reactive power components (Q1÷Q3 for phases L1 ÷L3) and corresponding three
active powers (P1÷P3).
Fig. 4.9: General Impedance (Z) Power Editing
If you set the phase power component values of a general impedance output to a
combination that is characteristic for any of standard type outputs the output type will be
reclassified to the standard type output after the editing is finished automatically.
Moreover, the upper three outputs can be set as following types :
• Fan , Heater
…
the output is used for fan/heater control. Then threshold temperatures On-
Temp. and Off-Temp. must be specified.
• Alarm ... the output is used for alarm signalling. Then Active State (on/off) must be
specified. If more outputs are set as alarm ones the outputs are numbered as AR1
÷
AR3
(Alarm Relay). Then, in the alarm setting you can select required affected relay for each
alarm event.
Next, there is the output control state parameter that can be set to :
• Control … the output is used for power factor control process
• 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.
• 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.
Next, there are listed :
• Sw. Count … 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
Clear
option.
By checking frequency of switching you can tune other power factor control parameters
optimally during the compensation system commissioning.
