Turbo-V 2K-G Pumping System User Manual / 87-900-968-01
Range Description
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
