4.1.21 Parameter 40 – Alarm Status
If an indication function from a nonstandard condition is set (see description of parameter 30 – alarm
setting), you can view alarm’s current status in the side branch of parameter 40.
Indication can be triggered by any of the nine conditions shown in Table 4.5. Parameter 40 is used for
detailed identification of condition that has triggered alarm indication. Alarm indication has been
triggered by those conditions whose value is
1 11 1
.
4.1.22 Parameters 43, 44 – Total Section Connection Time and Number of Section
Switching Operations
In the side branch of these parameters you can check the time that each section has been connected
for (parameter 43) and the number of switching operations for each section (parameter 44) since last
value reset.
The total section connection time is shown in thousands of hours. If the number is low, you can view it
at accuracy in the order of hours. Maximum value is 130 thousand hours.
The number of switching operations is shown in thousands. If the number is low, the value is shown
with a decimal point so that you can view it at accuracy in the order of single events, tens or hundreds
of switching operations. Maximum value is 4 million switching operations.
The numbers are kept in the controller’s non-backedup memory and stored in backed up memory
about every eight hours where it is maintained even on power supply outage. The numbers from the
last eight–hour interval are lost on voltage failure or controller initialization.
If a section’s contactor is replaced, the relevant output’s switching operation counter can be cleared by
editing it.
4.1.23 Parameter 45 – Type of Controller Error
The controller carries out self-diagnostic tests in regular intervals during the compensation process.
You can check the diagnostics’ results in this parameter.
It shows
E-00
E-00 E-00
E-00
if no errors have occurred. If the value is other than zero, the controller has
identified an error. Such a condition does not necessarily mean the controller is out of operation — in
such an event the controller supplier must be contacted and told about the identification value of the
type of error shown. Using this value, a specialist will then decide about the method of solving the
problem.
4.1.24 Parameter 46 – Control Time
When optimising controller parameter settings, it is sometimes required to monitor control time in
detail. You can view the control time’s current value in this parameter – it is shown in seconds as
countdown to the next control intervention.
For monitoring the control time to make sense, the control operation must not be halted — therefore
the control operation is enabled while viewing this particular parameter. Another difference while
viewing this parameter is automatic jump back to display of values measured; this automatic jump
takes only place after having viewed the control time for about 5 minutes from the last button press (it
takes place as soon as in about 30 seconds while viewing any other parameters).
4.1.25 Parameters 50, 51, 52 – Instrument Address, Communication Rate and
Communication Protocol
These parameters are only important in instruments featuring remote communication interface.
When setting up a RS-485 remote communication you have to specify the instrument’s address
(parameter 50) to one of the values from 1 to 253 (addresses 0, 254, and 255 are dedicated to special
