With P.20 at OFF, there is no tripping until the P.21 value is exceeded and the immediate
disconnection of the steps takes place.
With P.21 at OFF, the delay time is also constant.
With P.20 and P.21 both at OFF, the capacitor overload measurement is disabled as well
as the A07 alarm.
In these conditions, the display indicates --- instead of the overload measurement.
Whenever the capacitor banks are equipped with inductances to prevent harmonic
overload, P.20 and P.21 must be at OFF.
P.22 - Overload event counter reset time
Each time an A07 Capacitor overload alarm is generated, the event is registered by an
internal counter, which can be consulted by pressing the + key when the OVERLOAD %
LED is switched on. The counter indicates the number of capacitor overload events have
taken place over the time period defined by P.22. This parameter also defines the number
of hours during which the events remain stored. If no event has taken place during the
time period, the counter is cleared.
P.23 - Overload alarm reset time
Time period during which the A07 Capacitor overload remains active even though the
overload value has decreased below the alarm threshold.
P.24 - Unit of measure for temperature
It defines the unit of measure in degrees Celsius or Fahrenheit of the temperature
measurement and viewing along with the threshold setting linked to it.
P.25 -Fan start temperature
Sets the temperature above which the fan relay is activated, if any is programmed on the
last two steps.
P.26 - Fan stop temperature
Sets the temperature below which the fan relay is deactivated, if any is programmed
onthe last two steps. Cannot be set to a valuehigher than P.25.
P.27 - Temperature alarm threshold
Sets the temperature above which the alarm A08 Temperature too high is activated.
1.22 FUNCTIONS MENU SET-UP
With the controller is MANU mode, press the MODE key continuously for 5 seconds.
The SEt caption is shown on the display to indicate access to the parameters of the basic
menu. From this position press SCROLL and + keys at the same time for 5 seconds until
FU.S, indicating access to the parameters of the functions menu, is shown on the display.
