U = Indication of valve position (only where required). 0 to 10 Vdc → 0 to 100%
volumetric flow.
If the cables for the 24 Vac supply and the control signal 0 to 10 Vdc
(2 to 10 Vdc, 4 to 20 mA are routed separately, twisted pairs are not required for the
24 Vac cable).
Forced Control Feature
(Input Terminal YF/6)
0 Vac (Bridge G0 – YF)
24 Vac (Bridge G – YF)
1 to 9 Vdc at F
Control path A → AB closed
Control path A → AB open
Continuously variable low limit control 10% to 90% volume
flow (the higher value YF of Y takes priority).
This function is available with valves with a manufacturing
date of 990701 or later.
