LED Indicator
There is 1 LED that provides status information. This LED is an indicator of SLICE Distributor
status only; it does not indicate the status of any attached equipment.
A thorough understanding of the LED states will facilitate an efficient approach to
troubleshooting and a quick resolution to any problems.
SLICE Distributor Status
Unit off; no input power detected
Unit off; input power detected (input range OK); output power is active
Unit initializing
Unit on (input range OK); all outputs active
Input power is overvoltage –or–overcurrent condition is present
(If unit is on, cycle power to reset)
On/Off Pushbutton Switch
A momentary pushbutton switch is used for on/off control. When the unit is on
(LED is blue), all internal system electronics and output power are energized and
the unit is fully functional. (This is the normal operating mode.) When the unit is
off, the LED is either green (input power detected) or off (no input power).

Basic Care and Handling
The SLICE Distributor is designed to operate reliably in dynamic testing environments.
Though resistant to many environmental conditions, care should be taken not to subject the
unit to harsh chemicals, submerge it in water, or drop it onto any hard surface.
WARNING:
Electronic equipment dropped from desk height onto a solid
floor may experience as much as 10,000 g. Under these
conditions, damage to the unit is likely.
If you plan to store the unit, place it in a location with ambient temperatures below 30°C, low
relative humidity, and free from dust and direct sunlight. When not in use or if shipping is
required, we suggest that you always place the unit in the padded carrying case originally
provided with your system. When transporting the unit, treat it as you might a laptop
computer.
The SLICE Distributor is not user-serviceable and should be returned to the factory for
service or repair.
Shock Rating
The SLICE Distributor is rated for 500 g, 4 ms half-sine duration, in all axes.
Mounting Considerations
The unit should be securely bolted to the test article or dynamic testing device to provide the
best shock protection. Mounting methods and hardware selection should be carefully
calculated to withstand expected shock loading and facilitate proper grounding. Check bolt
tightness periodically to ensure that the unit is securely fastened to the baseplate or testing
platform. (See Appendix B for the unit’s mechanical specifications.)
Thermal Considerations
It is unlikely that the unit will overheat if common-sense measures are taken. In normal use,
the SLICE Distributor is bolted to a structure with enough thermal mass to serve as a heat
sink, keeping the temperature well within acceptable limits. However, when used
continuously at the maximum output level, the unit may get very warm to the touch. Since
the system draws the most power when armed, running the calibrations and arming as late
as possible will minimize self-heating, particularly in embedded applications. Should you
have any questions about using the SLICE Distributor in your environment, please contact
DTS.

SLICE Distributor User’s Manual February 2018
support.dtsweb.com 813000-30030-MAN (Rev. 3)
Power Management
The SLICE Distributor should be powered from a high-quality power source with output
voltage and current ratings appropriate for the installation. It does not contain an internal
power source, but has separate connectors to support main power and back-up power inputs.
The SLICE Distributor contains power conditioning circuitry with a wide input range and well-
regulated outputs. It will boost input voltages at the low end of the specified range in order
to maintain a consistent output voltage. This conversion, however, will come at the expense
of the supplied input current. A simple voltage measurement at the cable end that connects
directly to the SLICE Distributor will verify whether the unit is receiving sufficient input voltage.
Maximum Power Consumption
The maximum power consumption is 180 W.
Maximum Input Power
The maximum input power is 15 VDC nominal (9-18 VDC range) at 10 A.
Maximum Output Power
The combined maximum output power available via the 4 SLICE system connectors is 120 W
(12 V at 10 A). The maximum output power available per SLICE system connector is 12 V
at 4 A. The maximum output current available via the AUX connector is 2.5 A (input VDC = output VDC).
Charging/Powering Attached Equipment
When sufficient main input power is connected to the SLICE Distributor, it will simultaneously
power and charge any attached SLICE DAS containing an internal battery.
1
The length of
time required to charge attached equipment depends primarily on the discharge state of the
batteries. The SLICE Distributor does not need to be on for attached equipment to charge.
WARNING:
Interconnecting SLICE equipment while signals/power are active/hot is not
supported.
The SLICE Distributor uses a common 12-conductor SLICE system chain
connector that supports power, communication and control signals. If a port or
cable is hot, it is possible that the locking clip or incorrectconnector orientation
might randomly short pins and damage the equipment. Application of power
and other signals should occur after all cables have been connected to the
SLICE Distributor. DTS strongly suggests following this procedure at all times
to avoid potential damage to your equipment.
1
The SLICE Distributor does not contain a battery charging circuit and cannot be used to charge any external
device/battery that does not contain its own battery charging circuitry.

Power Requirements of SLICE Equipment
SLICE DAS use extensive power management to minimize power consumption. The lowest
power demand condition is during charging when power is off. Current demand is at its
maximum when the systems are fully armed and powering full sensor loads.

Grounding
The SLICE Distributor has integrated mounting holes that will provide a simple method of
grounding the entire data acquisition system when bolted to a properly-grounded test fixture.
DTS recommends checking continuity between the SLICE Distributor and the test fixture to
confirm resistance readings of <1 ohm.
Troubleshooting Basics
Begin troubleshooting by checking the operational state of the SLICE Distributor alone. DTS
suggests always using the connection sequence below to avoid possible damage from hot
swapping the cables.
1. With the unit off (and no DAS connected), connect the SLICE Distributor’s power
source to the SYS connector.
–If the status LED is green, then voltage input levels are within specifications and
main output power is active. Proceed to step 2.
–If the status LED is off, this can mean that the input voltage is too low or input
polarity is reversed. You will need to correct this before proceeding.
–If the status LED is red, this can mean:
a) Input voltage is too high. You will need to correct this before proceeding.
b) Overcurrent condition is present. This likely means the SLICE Distributor is
not working properly. Contact DTS Support for assistance.
2. When the status LED is green, turn on the SLICE Distributor.
3. When the status LED is solid blue, the SLICE Distributor is on and fully functional (all
internal system electronics and output power are energized). This is the normal
operating mode.

SLICE Distributor User’s Manual February 2018
support.dtsweb.com 10 13000-30030-MAN (Rev. 3)
If the SLICE Distributor is operating normally, the next step is to add the DAS. DTS suggests
always using the connection sequence below to avoid possible damage from hot swapping
the cables.
1. With the unit off and power not connected, connect the SLICE DAS to the SLICE
system connectors.
2. Connect the SLICE Distributor’s power source to the SYS connector.
3. When the status LED is green, turn on the SLICE Distributor.
–When the status LED is solid blue (normal operating mode), then inspect the LED
indicators on the SLICE DAS for system health.
–If the status LED is red, this can mean input voltage is too high or overcurrent
condition is present. You will need to correct this before proceeding.
4. Connect the Ethernet comm cable from the SYS connector to your PC.
If at any time the status LED indicator shows an error or fault condition, you will need to
correct this before proceeding. (The LED is an indicator of SLICE Distributor status only; it
does not indicate the status of any attached equipment.) A fault signal generated by the
SLICE Distributor or SLICE DAS is forwarded externally via the AUX and SYS connectors
and will prevent you from arming your system. When the DAS is recording data, the status
signal from the AUX and SYS connectors will be high; the status signal will be low for all
other states where the DAS is on and connected to the SLICE Distributor.
