HA – Automatic high-pressure related control
HA.U1, HA.U2 electric override, two-point
With the HA.U1 or HA.U2 control, the beginning of control
can be overridden by an electric signal to a switching sole-
noid. When the override solenoid is energized, the variable
motor swivels to maximum swivel angle, without intermedi-
ate position.
The beginning of control can be set between 1150 and
4350 psi (80 and 300 bar) (specify required setting in plain
text when ordering).
