RANGE
B7 – Start/Stop
0 = Stop
1 = Start
B6 – Low Speed
0 = off (set the "target speed"(In Buff byte-8) at" high speed" (Out. Buff.
byte-1))
1 = on (set the "target speed" (In Buff byte-8) at "low speed" (Out. Buff.
byte-3))
B5 – Soft Start
0 = 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 least 3 months)
1= on
B4 – Active Stop
0 = off (after a stop command the controller stop driving the motor, the
pump will decrease its speed by friction with gas load)
1 = on (after a stop command the controller will brake the pump using the
motor, activate this function only if you don't use the vent valve and for few
cycles at week)
B3 - Vent Valve On/Off
0 = close,
1 = open
(Valid only if in Parameter buffer Byte-15-B1 = 1, and Byte-15-B2 = 0)
B2 – Purge Valve On/Off
0 = close,
1 = open,
(Valid only if in Parameter buffer Byte-15-B1 = 1, and Byte-15-B2 = 0)
B1 – Heather Jacket Enable
Specific option, not available on standard models
B0 – Stop Speed Reading
0 = no (after a stop command the user can't know the real pump speed)
1 = yes (after a stop command the user can know the real rotor speed; see
In Buff. Byte Offset 6)
(this function is available for the latest controllers, otherwise will be ig-
nored)
Hz 475 - 555 High Speed Value
Set the high rotational speed, default = 555
Hz 475 - 555 Low Speed Value
