Analogue input “0-10V”,
Fig. 2, item 18
The signal at the analogue input “0-10V” specifies
the setpoint for the control mode set with the
“mode” rotary switch (Fig. 3):
•
Δ
p-c: 0V = H
min
, 10V = H
max
•
Δ
p-v: 0V = H
min
, 10V = H
max
• n-c: 0V = min. speed, 10V = max. speed
• The signal at the analogue input “0-10V” over-
rides the value set at the “setpoint” knob and the
setpoint transmitted via the RS 485 bus.
