4.3. Power Connection
The power connection is located on the rear panel of the chassis. Unless you request
otherwise, the E-500/E-501 system will be set up for the line voltage we believe
predominant in your country.
How to adapt E-500/E-501 system to a different line voltage:
If your system uses a 19” chassis (E-500.00), it is equipped with a wide-range power
supply and with fuses that are admissible for both 115 V and 230 V operation. No
settings need be changed when connecting the device to a different line voltage.
If your system uses a 9.5” chassis (E-501.00), it requires new fuses when it is to be
connect to a different line voltage. Replace both fuses as described in “AC Power
and Line Fuses” on p. 60.
4.4. First Electrical Checks
Check the device electrically when using it for the first time after unpacking. Perform these
steps:
1. Connect the power cord.
2. Switch the device on without any piezo actuators connected. The power switch is at the
rear next to the power cord socket.
3. Now the green LED on the amplifier module lights up.
4. If an E-517 Interface / Display module is installed:
The display shows the main screen, see E-517 user manual for details.
5. Set the SERVO switch on the E-509 module to OFF.
6. If an E-517 Interface / Display module is installed:
Turn the DC-OFFSET potentiometer and watch the voltage display. The voltage reading
is the current output voltage at the PZT output sockets.
The position values in the display have no meaning, because the piezo actuators and
sensors are not yet connected.
If these steps could be performed without unexpected results, the device has passed the
electrical checks.
4.5. Connecting Cables
INFORMATION
Each E-509 sensor / servo-control module is calibrated with one particular piezo actuator.
That piezo actuator must always be connected to that same controller channel. Labels on the
rear panel of the device indicate the serial numbers of the piezo actuators that belong with
each channel.
After the system has passed the electrical checks, the piezo actuators can be connected
and the system can be operated. Follow these steps:
1. Switch the device OFF.
2. Connect the piezo actuators.
Each piezo actuator is equipped with cables for the piezo operating voltage and for
the sensor, if present. Connect the first cable to the PZT output socket on the
amplifier module and second with the sensor input socket on the piezo servo-
controller.
If capacitive sensors are used, two sensor cables must be connected to the servo-
controller. The cable labeled ´T´ must be connected to the T socket (target signal)
and the cable labeled ´P´ to the P socket (probe signal).
