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.
