P.10 - Connection sensitivity. This parameter sets the speed of reaction of the controller. With small values of P.10 the
regulation is fast (more accurate around the setpoint but with more step swithchings). With high values instead
we'll have slower reactions of the regulation, with fewer switchings of the steps. The delay time of the reaction is
inversely proportional to the request of steps to reach the setpoint: waiting time = (sensitivity / number of steps
required).
Example: setting the sensitivity to 60s, if you request the insertion of one step of weight 1 are expected 60s (60/1 = 60).
If instead serve a total of 4 steps will be expected 15s (60/4 = 15).
P11 ... P18 - Function of output relays 1 ... 8:
OFF = Not used .
1 .. 32 = Weight of the step. This relay drives a bank of cpacitors which power is n times (n = 1...32) the
smallest power defined with parameter P.06.
ON = Always on.
NOA = Alarm normally de-energized. The relay is energized when any alarm with the Global alarm
property arises.
NCA = Alarm normally energized. The relay is de-energized when any alarm with the Global alarm
property arises.
FAN = The relay controls the cooling fan.
MAN = Relay is energized when device is in MAN mode.
AUT = Relay is energized when device is in AUT mode.
A01 ... A12= The relay is energized when the alarm specified is active.
P19 - Setpoint (target value) of the cosø. Used for standard applications.
P20 - Language of scrolling alarm messages.
