GENERAL DESCRIPTION
CTL Series transducers combine a current transformer and a signal
conditioner into a single package. This provides higher accuracy, lower wiring
costs, easier installation and saves valuable panel space.
The CTL Series transducers have jumper selected current input ranges and
industry standard 0-10 VDC or 4-20 mA outputs. The CTL Series is designed
for application on “linear” or sinusoidal AC loads. Available in a split-core or
solid-core case. Select the CTL Series for constant speed loads or On/Off loads.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so, can be potentially harmful to persons or
equipment in the event of a fault to the unit.
CAUTION: Read complete
instructions prior to installation
and operation of the unit.
CAUTION: Risk of electric shock.

INSTALLATION
Run wire to be monitored through opening in the sensor. The CTL Series
transducers work in the same environment as motors, contactors, heaters, pull-
boxes, and other electrical enclosures. They can be mounted in any position or
hung directly on wires with a wire tie. Just leave at least one inch (25.4 mm)
distance between sensor and other magnetic devices.
Split-Core Versions
Press the tab in the direction as shown to open the sensor. After placing the
wire in the opening, press the hinged portion firmly downward until a definite
click is heard and the tab pops out fully.
Important!
Keep Contact
Area CLEAN!
To Open
Press Tab
Toward Hinge.
KEEP SPLIT-CORE SENSORS CLEAN.
Silicone grease is factory applied on the mating surfaces to prevent rust and
improve performance. Be careful not to allow grit or dirt onto the grease in the
contact area. Operation can be impaired if the mating surfaces do not have good
contact. Check visually before closing.
OUTPUT WIRING
Connect control or monitoring wires to the sensor. Use up to 14 AWG copper
wire and tighten terminals to 7 inch-pounds torque for solid-core models and 9
inch-pounds torque for split-core models. Be sure the output load or loop power
requirements are met (see diagram).

RANGE SELECT
CTL series transducers feature field selectable ranges. The ranges are factory
calibrated, eliminating time consuming and inaccurate field setting of zero or span.
1. Determine the normal operating amperage of your monitored circuit
2. Select the range that is equal to or slightly higher than the normal operating
amperage.
3. Place the range jumper in the appropriate position.
TROUBLE SHOOTING
0-10 VDC OUTPUT MODELS
1. Sensor Has No Output
A. Polarity is not properly matched. Check and correct wiring polarity.
B. Monitored load is not AC or is not on. Check that the monitored load is AC
and that it is actually on.
C. Split Core models: The core contact area may be dirty. Open the sensor and
clean the contact area.
2. 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. Output load too low. Check output load, be sure that it is at least 100K
and preferably 1 M.
C. Monitored current is below minimum required. Loop the monitored wire
several times through the aperture until the “sensed” current rises above
minimum. Sensed Amps = (Actual Amps) x (Number of Loops). Count
loops on the inside of the aperture.
3. 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.
4-20 mA OUTPUT MODELS
1. Sensor Has No Output
A. Power supply is not properly sized. Check power supply voltage and
current rating.
B. Polarity is not properly matched. Check and correct wiring polarity
C. Split Core models: The core contact area may be dirty. Open the sensor and
clean the contact area.
2. 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. The load current is not sinusoidal.
C. Monitored current is below minimum required. Loop the monitored wire
several times through the aperture until the “sensed” current rises above
minimum. Sensed Amps = (Actual Amps) x (Number of Loops). Count
loops on the inside of the aperture.
3. Sensor Is Always At 4 mA
A. Monitored load is not AC or is not on. Check that the monitored load is
AC and that it is actually on.
4. Output Signal Is Always At 20 mA
A. The jumper may be set in a range that is too low for current being
monitored. Move jumper to the correct range.
