Here is a simple solution for using the FDU on single pump irrigation systems with a pipe fill operation and a sleep mode operation.

Operational Parameters
parameter : function : Suggested start point
500 : Running Pressure : Dependent on transducer
321B : Pipe Fill Speed : 30 - 35 Hz
822 : Pipe Fill Pressure : About 10-20% running pressure
321A : Minimum speed : Set to keep pumping (30-40Hz)
322A : Maximum speed : 50Hz
28F : Sleep frequency : Equal to or greater than min speed (321A)
28G : Sleep Delay : 30 seconds
28H : Wakeup pressure : 50-90% of running pressure

Connections
Link : #10 to #20
Start : #8 to #11
Pressure Transducer : #3 (-ve) to #11 (+ve)

CODE


Setup in this order:

212 = keyboard

213 = remote

214 = R



281 = ON

282 = 2

287 = 0%

288 = 98%

28F = 30Hz

28G = 30 seconds

28H = 30%

28I = Fall



441 = !A1

821 = ANIN2

822 = 10%



234 = A

311 = 10S

315 = 10S

321A = 30Hz

322A = 50Hz

343A = ON



416 = 4-20mA; Set link S$ on pcb to current



234 = B

321B = 30Hz

322B = 50Hz

343B = Invert



234 = Digin3
