Gluing the piezo actuator on
1. Glue the dowel pins into the locating holes
of the piezo actuator‘s base body or into
the equipment intended for mounting the
piezo actuator.
2. Align the piezo actuator and the equipment
so that each dowel pin fits in the correspon-
ding locating hole.
3. Glue the piezo actuator to the equipment.
4. Wait until the adhesive has hardened
completely.
5. Check for firm seating of the piezo actuator
in the equipment.
Checking the Connection of the Protec
tive Earth Conductor
X
Make sure that the contact resistance at
all protective earth connections is <0.1 Ω
at 25 A.
X
If ground loops occur, contact the PI custo-
mer service department.
Screwing the Load
Tools and accessories
▪
▪
Suitable fixing screw(s) (depending on the
model; refer to user manual)
▪
▪
Suitable tool to hold the movable part
firmly
▪
▪
Screwdriver or wrench
Requirements
▪
✔
You have fixed the piezo actuator properly.
▪
✔
The piezo actuator is not connected to the
electronics.
▪
✔
Models with stranded wires: The piezo
actuator is discharged and short-circuited.
▪
✔
The distance between the center of gravity
of the load and the center of the movable
part is as small as possible in all directions.
Screwing the load
1. Align the load so that the mounting holes
(or mounting hole) in the movable part of
the piezo actuator can be used to fix the
load.
2. Hold the movable part of the piezo actuator
firmly.
3. Fix the load to the movable part of the
piezo actuator. Do not exceed the respec-
tive maximum permissible torque for the
movable part and the screws used (refer to
user manual).
4. Loosen the movable part of the piezo
actuator that was held firmly so it can move
freely again.
The instructions required for startup and
operation are in the manual for the electronics
used.
The piezo actuator must be discharged in the
following cases:
▪
▪
Before short-circuiting
▪
▪
When not in use
▪
▪
Before reconnecting if the connecting cable
is accidentally pulled out of the electronics
during operation
▪
▪
Before assembly work
Discharging the Piezo Actuator Connec
ted to the Electronics
X
Set the piezo voltage on the electronics to
0 V.
Discharging the Piezo Actuator Not
Connected to the Electronics
Piezo actuator without connector:
1. Ensure adequate protection against
touching live parts.
2. Short-circuit the piezo actuator for at
least a few seconds with a suitable 10 kΩ
discharge resistor.
Piezo actuator with connector:
X
Connect the piezo actuator's voltage plug
to the switched-off electronics from PI for
at least a few seconds.
ShortCircuiting a Discharged Piezo
Actuator
1. Disconnect the piezo actuator from the
electronics if it is still connected.
2. Short-circuit the piezo actuator by twisting
the stranded wires, using a suitable shor-
ting clamp or a suitable shorting plug.
