Page parameters 1/4:
1 : T1 : pulse time on one declogging SV.
Adjustable from 3 to 255 1/100th seconds (reachable at level 1 or above).
2 : T2 : rest time between two pulses of declogging SV.
Adjustable from 1 to 255 seconds (reachable at level 1 and above ).
3 : T2A : second rest between two pulses of declogging SV.
T2A time (shorter than T2) replaces T2 time if accelerated running (pressure>threshold T2A).
Adjustable from 1 to 255 seconds (reachable at level 1 and above ).
4 : T3 : rest time between two declogging cycles.
Adjustable from 0 to 255 minutes (reachable at level 1 and above). If adjusted to 0 : not active.
5 : T4 : maximum time without declogging cycle.
If the device did not have any declogging cycle for the quantity of hours which is adjusted, the ongoing cycle is stopped
(if stop in cycle) and a declogging cycle is launched.
Remark: T4 time is reset at each pulse on any SV.
Adjustable from 0 to 255 hours( reachable at level 1 and above ). If adjusted to 0 : not active.
6 : Quantity of declogging SV.
Adjustable from 1 to 18, according to the quantity of SV which are connected (reachable at level 1 and above).
7 : Adjustment of the type of declogging stop, in case we lose the running order :
« End of cycle » : the ongoing cycle ends up.
« On cycle » : cycle stops during its running (at the SV where cycle is, at the end of the T2 time). It will start
again where it was. (reachable at level 1 and above).
8 : Condition to let the declogging cycle, linked to T4 time, runs.
Two possible choices : « whatever input I1 » or « if I1 Input=1 »
9 : Display of ongoing protection level.
10 : If press this area : go back to page menu.
11 : If press this area : go back to main page.
12 : If press this area : goes to the next adjustments page.
