Place wire to be monitored through sensor aperature. Care
should be taken to ensure current flow is in accordance
with any directional arrows on sensor and as noted in the
figure, above right.
DT Series transducers work in the same environment as
motors, contactors, heaters, pull-boxes, and other electri-
cal enclosures. They can be mounted in any position or
hung directly on wires with a wire tie. For optimal perfor-
mance, ensure unit has been energized for a period of 20 min-
utes prior to sensing operation.
Description
Installation
Wiring & Mounting Information
Range Select
DT Series transducers feature field selectable ranges. The
ranges are factory calibrated.
1. Determine the nominal operating amperage of moni-
tored circuit
Trouble Shooting
DT Series transducers combine a Hall Effect sensor and
a signal conditioner into a single package. This provides
higher accuracy, lower wiring costs, easier installation
and saves valuable panel space. DT Series are available
with 0-20 mA, 4-20mA, 0-5VDC or 0-10VDC outputs.
2. Using jumper select, choose the range that is equal to
or slightly higher than the nominal operating amperage.
3. Place the range jumper in the appropriate position.
1. Output Signal Too Low
A. The jumper may be set in a range that is too high for
current being monitored. Move jumper to the correct
range.
B. Power supply is inadequate. Check power supply.
Make sure it is of sufficient voltage with all loads at
maximum. DT Series consumes 2.0 VA.
C. Output load too high on current output models.
Check output load, be sure it is no more than 500
Ω
.
Output load too low on voltage output models. Check
output load, be sure it is at least 10K
Ω

0-20mA & 4-20mA:
The current loop is powered by the DT Transducer.
Maximum loop impedance is 500
Ω
.
0-5VDC & 0-10 VDC:
Signal is powered by the DT Transducer. Minimum output
load (impedance) is 10K
Ω
.
Current Direction:
Ensure the direction of monitored current is the same as
the direction shown on the diagram. The unit will not
operate properly if the current is opposite the direction of
the arrow.
Note:
For power terminals 1 & 2 there is no assumed polarity,
either can be wired as positive (+) or negative (-).
2. Output Signal is always at maximum
A. The jumper may be set in a range that is too low for
current being monitored. Move jumper to the correct
range.
3. Sensor has no output
A. Polarity is not properly matched. Check and correct
wiring polarity.
B. Monitored load is not DC or is not on. Check that
the monitored load is DC and that it is actually on.
