In order to don't overload the controller's internal serial link, following precautions are taken:
•
The parameters are written from the gateway to the controller only when their value changes.
•
The parameters are never read back from the controller to the interface. The controller's response at the
write command (ACK, NACK, etc) is used to establish if the writing succeed or not.
RANGE
RES
B4 – Verify Line Select
(the auto voltage selection mismatch the real input voltage)
B3 – Power Fail
(internal circuitry failure)
B2 – Controller Over-Temperature
("Controller Power Section Temperature" or "Controller CPU Section Tem-
perature" are over the limit)
B1 - Pump Over-temperature
("Pump Bearing Temperature" or "Pump Body Temperature" are over the
limit)
B0 – Check Connection To Pump
(the connection between controller and pump missing)
Flow Meter Reading
(Specific option, not available on standard models)
- B0 – Start/Stop Status
0 = Stop
1 = Start
B1 – Low Speed Status
(Read the "Low Speed" function status (Out Buff byte-0 B6))
0 = off (the "target speed" (In Buff byte-8) is" high speed" (Out. Buff.
byte-1))
1 = on (the "target speed" (In Buff byte-8) is "low speed" (Out. Buff.
byte-3))
B2 – Soft Start Status
0 = on
1 = off
(this function is active at first pump run-up and can't be deactivated by the
user, after first run-up activate this function only if the pump has been
stopped for at least3 months; this procedure will take 1h)
B3 – Vent Valve Status
0 = close
1 = open
B4 – Purge Valve Status
0 = close
1 = open
B5 – Set Point Status
0 = open
1 = closed
B6 – Flow meter Alarm Status
Specific option, not available on standard models
B7 – Not Used
