NOVAR 2600 Operating Manual
The alarm functionality is similar to the standard type alarms. The only difference is that you can set
not only the threshold temperature ( limit ) but the polarity of its deviation too (
>
or
<
). Therefore, the
alarm can be activated by both overheating ( > limit ) and overcooling ( < limit ).
4.3.3.6 OoC - “Out of Control” Alarm
This alarm can be used for signalling of states when power factor control doesn't run. Such states can
be :
•
the controller is switched into the manual state
•
the controller is switched into the control state, but power factor control process doesn't take
place due to any cause such like :
•
the instrument is forced into
the standby
state ( see below for details )
•
automatic output recognition (AOR) process in progress
•
the CT connection test in progress
If such state lasts continuously for preset delay time, the alarm gets active. As soon as the power
factor control process resumes the alarm is deactivated immediately.
4.3.3.7 RCF - “Remote Control Failure” Alarm
This alarm will serve for remote control problem signalling in future. Now it is not functional.
4.3.4 Control / Manual State Indicator and
Switch
The icon does not comprise any parameters but it indicates one of two instrument main states – t
he
control state
or
the manual state
.
By selection of the icon, you can toggle from the control state to the manual state and vice versa.
Confirmation of such command is required first and after that the instrument state changes. The
selected state and, in case on the manual state the last outputs' states too are kept even if power loss
occurs.
If the instrument is in the manual state, corresponding flashing indicator
appears at the main
power factor control screen.
For details of the main controller states, see appropriate chapter further below.
4.3.5 Power Factor Block Factory Setting
With this option you can force all of the parameters of the power factor control block into the default
values. Overview of the default setting follows. The alarm parameters default setup can be found in
appropriate table above.
