Before you switch on the system, please check:
•
The main voltage supplied in your country is the same as installed for the system.
(Check the voltage label on the bottom side of the electronics and the datasheet
on point 9.2.)
•
The potentiometer should be in maximum counter clockwise position (Pos. 0 or
Pos.1 depending on the operation mode)
•
The power switch should be in the off position
•
Connect the power cable.
•
Connect the piezo-element by using the LEMO connector. Be sure the cables are
connected properly to the electronics.
•
Switch the system on (power = on). If the light „CL ON“ is on, press the button
„Closed Loop“. The display shows the output voltage in open loop operation.
•
Turn the potentiometer to the maximum clockwise position. The display shows the
maximum position. The actuator is now in position 4. (see diagram 1)
•
Turn the
potentiometer to the maximum counter clockwise position (Pos. 1).
•
Switch on the closed loop (push the button „Closed Loop“, „CL ON“ is illuminated).
The actuator moves to its zero position in closed loop mode
(Pos. 2), the displays shows 0.0µm if there is no offset to the system. Offset is
accomplished by the offset potentiometer or external offset (e.g. a load). Because
of the fast motion of the actuator to Pos. 2 a cracking noise can be heard. This is
normal and not a malfunction!
•
Turn the potentiometer to the clockwise position again. The actuator makes its
maximum movement in closed loop mode (pos. 3). The total motion in closed loop
mode is pos. 3 - pos. 2. The specific value for that axis is given in the calibration
curve of the actuator (see the calibration protocol for your actuator).
•
Turn the potentiometer to its counter clockwise zero position, switch off the closed
loop switch (push „Closed Loop“, „CL ON“ is off).
•
If the procedure is done you can switch off the electronics.
•
Before you switch off the electronics, be sure that the potentiometer is in the left
zero position and the closed loop switch is switched off!
