(Y40) 3-way valve external buffer tank
230 V 1N~.
2.5 m cable 1.5 mm²
The 3-way valve is connected to the following terminal blocks: (Y40) 3-way
valve, extension card X6:
(Y40) 3-way valve, charging/discharging buffer
Relay output (black): X6 pole 4
Phase (brown): X6 pole 5
Neutral (blue): X6 pole 7
Check the function by test running the 3-way valve in the "Installer/Service/
Function test" menu in the control system.
In the “DOWN” position on the function menu, port
▲
should be open (turn
the knob on the motor clockwise, CW). In the “UP” position, port
■
should
be open (turn the knob on the motor counterclockwise, CCW).
The motor is fi tted to the 3-way valve by a screw. To unfasten the motor:
remove the knob by pulling it off, unfasten the screw and remove the motor.
To prevent faults, turn the actuator and 3-way valve to the starting position
for fi tting as shown in the fi gures. Pull out the knob on the actuator and turn
to the central position.
Port
●
should be completely open; ports
■
and
▲
should be partially open.
Ensure that the groove in the white shaft coupling is in position as shown
in the fi gure. The 3-way valve and actuator can then be fi tted together as
shown in the fi gure or turned in 90-degree steps relative to each other.
If ports
▲
and
■
have been shifted during the hydraulics connection, the
motor can be reconnected to change its direction of rotation. This is done
using two jumpers inside the motor.
NOTE: the direction of rotation cannot be changed by swapping the
black and brown cables.
