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.
