1) Introduction
The inertial shaker (DYN-IS-5) is used for small structures requiring
excitation in low frequency bands. The shaker is directly connected to the
structure and the inertia motion of the shaker mass provides the necessary
forces to the structure. The shaker has a small, lightweight design that
provides high mobility. For this reason, it is suitable for use as a portable
shaker.
2) General Information
2.1) Unpacking and Inspection
Dynalabs products provide adequate protection for undamaged products to be
transported. Document the damages that occur indirectly during the transport
and contact the customer representative. Check all components of the shaker.
If there is a defect, please contact us.
2.2) System Components
DYN -IS-5 has the following components:
- Electrodynamic Shaker
- Amplifier (DYN-SA-150)
- Power Adapter
- Signal Cable
- Wrench
- Ground Cable
- User Manual
2.3) Theory of Operation
DYN-IS-5 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-IS-5 has a stationary
coil (drive coil) whose current is controlled to produce vibration. The
stationary magnetic field is produced by a magnet.

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.

All rights reserved. Reproduction or issue to third parties in any form whatsoever is not permitted without written authority from the proprietors.

3.1.2-) Internal Signal Mode:
The amplifier can generate sine signal from 1 Hz to 15 kHz 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-IS-5 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-IS-5 does not require forced cooling. Air convection cooling is
sufficient for the force levels given in the specifications.
3.4) Frequency Response
The DYN-IS-5 has a relatively flat force response of 5N after 140Hz and
can achieve 5N at approximately 50 Hz. The following figure shows the
Force (Newton) over applied Voltage (Volt) frequency response of DYN-
IS-5.
FOR FIXED FREQUENCY SINE TESTING, APPLICATION OF VOLTAGE
LEVELS ABOVE 0.5V FOR LONG DURATIONS (>1MIN) CAN
PERMANENTLY DAMAGE THE SHAKER.
THE SHAKER SUSPENSION NATURAL FREQUENCY IS ABOUT 74 HZ.
ESPECIALLY FOR FIXED FREQUENCY SINE TESTING, THE USER
SHOULD ALWAYS LOWER THE GAIN FOR THE FREQUENCY BAND OF 50-
170 HZ. OTHERWISE, DUE TO THE HIGH RESPONSE OF THE SHAKER
AROUND ITS RESONANCE FREQUENCY, VERY HIGH AMPLITUDES OF
VIBRATION (⁓70N) WILL OCCUR AND PERMANENTLY DAMAGE THE
SHAKER.
THE INTERNAL SINE SIGNAL GENERATOR SUPPLIES A CONSTANT
VOLTAGE OF 0.3VAC. PLEASE LOWER THE GAIN IN THE VICINITY OF
THE NATURAL FREQUENCY AS HIGHLIGHTED ABOVE.

3.5) Force Transducer Mounting
The DYN-IS-5 has a 10-32 UNF screw interface for force transducer
mounting. Simply remove the Shaker Head by turning it counter clockwise
and mount the force transducer. In order to tighten the force transducer
properly, hold the flange of the screw with the supplied wrench or any other
tool available as shown.

NEVER APPLY FORCE ON THE SHAKER BODY TO REMOVE THE
SHAKER FROM THE MOUNTING SURFACE!

ALWAYS USE A WRENCH AT THE FORCE TRANSDUCER TO
REMOVE THE SHAKER FROM THE MOUNTING SURFACE!

4) Maintenance and Troubleshooting
The DYN-IS-5 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.
Do not apply high levels of axial force on the shaker. The suspension spring
is designed to carry the shaker weight only.
Inadequate mounting of force transducers or shaker head can lead to
permanent damage to the shaker. If such a case happens, please send the
shaker to Dynalabs for 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-IS-5 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.
5.1) Grounding
The shaker is internally grounded via the power adapter. However, if further
grounding is necessary a grounding socket is available on the shaker as shown.
Appropriate grounding cable is also supplied with the shaker.
