2.3) Theory of Operation
DYN-PM-10 is an electromagnetic actuator. Electromagnetic actuators are
basically a voice coil consisting of magnet and coil. The moving element can
be a coil or magnet depending on the design requirements. The moving
element is usually suspended by an elastic spring. DYN-PM-10 has a
stationary coil (drive coil) whose current is controlled to produce vibration.
The stationary magnetic field is produced by a magnet.

3) Operation and Installation
3.1) General
The general shaker connector configuration is given below.
The Gain Knob is a push-pull and rotational switch. The amplifier is in
External Signal Mode when the Gain Knob is pushed in and the amplifier is
in Internal Signal Mode when it is pulled out.
In order to protect the amplifier from electrical problems, it is advised to turn
the Gain Knob counter clockwise to the lowest gain position before
connecting the external signal cable or before changing operational modes.

3.1.1-) External Signal Mode:
Connect DC power source and drive signal to shaker power input and signal
input respectively. Start the external signal source. Adjust the Gain of the
amplifier by turning the Gain Knob clockwise.
3.1.2-) Internal Signal Mode:
The amplifier can generate sine signal from 1Hz to 15kHz with 1 Hz
increments that the user can adjust with the Sine Frequency Generator
Switch. Connect DC power source and drive signal to shaker power input.
Pull the Gain Knob out.

Raise or lower the Sine Frequency Generator Switch to the desired Sine
frequency. Adjust the Gain of the amplifier by turning the Gain Knob
clockwise. The frequency of the generated sine signal will be visible on the
LCD Screen.
3.2) Power Requirements
DYN-PM-10 has an external power amplifier which is powered by its power
adaptor. Please note the output voltage and current ratings of the adaptor if
a replacement adaptor is to be used.
3.3) Cooling
DYN-PM-10 does not require forced cooling. Air convection cooling is
sufficient for the force levels given in the specifications.

4) Maintenance and Troubleshooting
The DYN-PM-10 shaker is a sealed device requiring no maintenance if the
operating instructions described in this manual are followed. Repair of the
coil, exciter body or magnet core should not be attempted. Please return the
shaker to DynaLabs for proper repair.
5) Safety
Please ensure that this manual section is reviewed and understood prior to
installation, operation or maintenance of the equipment. The danger of
electrical shock or fire always exists in electrical equipment.
The DYN-PM-10 Shaker is designed for safe operation. Safety features
such as electrical insulation on outer surfaces are provided for the safe
operation of the shaker system. Always monitor the applied voltage to the
amplifier and shut down the shaker if the temperature of the shaker body
rises drastically or smoke is observed from the shaker due to high voltage
levels applied.
