Red Lion CTR - Manual (Page 2)

INSTALLATION
Run wire to be monitored through opening in the sensor. Be sure the
monitored current flows in the same direction as the arrow on the sensor. The
CTR 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.
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 9 inch-pounds torque. Be sure the output load or
loop power requirements are met (see diagram).
Connection Notes:
„ Captive screw terminals.
„ 14-22 AWG solid or stranded.
„ Observe Polarity
„ See label for ranges & jumper positions
Loop Voltage Requirements:
V
L
= 12V + (R
L
x 20 mA)
Where: V
L
= Min. Loop voltage
R
L
= Loop Resistance
RANGE SELECT
CTR 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
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. Output load too high. Check output load, be sure that V
L
does not exceed
40 VDC.
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 4mA
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 20mA
A. The jumper may be set in a range that is too low for current being
monitored. Move jumper to the correct range.
