Switch off input variable
You can use this parameter to set which measured temperature value is to
be used to switch off the cooling stage. You can select the following options:
▪
Upper oil temperature
▪
Hot-spot temperature
▪
Ambient temperature
▪
Lower oil temperature
▪
OLTC oil temperature
▪
Generic temperature
To select the input variable for switching off the cooling stages, proceed as
follows:
1.
Go to
Settings > Parameters > Cooling stage X > Switch off input
variable
.
2.
Select the option you want from the list box.
3.
Press the
Accept
button to save the modified parameter.
Switching point
You can use this parameter to set the temperature at which the cooling
stage is to be switched on or off. If the temperature exceeds the switching
point, the cooling stage is switched on. If the temperature is less than the
switching point minus the optional hysteresis, the cooling stage is switched
off.
To set the switching point, proceed as follows:
1.
Go to
Settings > Parameters > Cooling stage X > Switching point
.
2.
Enter the value you want.
3.
Press the
Accept
button to save the modified parameter.
Hysteresis
You can use this parameter to set a hysteresis below the switching point.
The cooling stage is only switched off if the temperature is less than the
switching point minus the hysteresis.
To set the hysteresis, proceed as follows:
1.
Go to
Settings > Parameters > Cooling stage X > Hysteresis
.
2.
Enter the value you want.
3.
Press the
Accept
button to save the modified parameter.
Switch-on delay
You can use this parameter to set the switch-on delay for the cooling stage.
The cooling stage is only switched on if the measured temperature is greater
than the switching point for longer than the set switch-on delay.
