SOLID CORE AND SPLIT CORE 4-20 MA OUTPUT CURRENT SENSORS

WARNING
The secondary of the 5A Current Transformer (C.T.)
must be shorted together before the power may be
turned on from the device.
For applications in which the normal operating current is
greater than 200 or 250 Amps, depending on the model, or for
conductor diameters larger than 0.75 in. (19 mm) in diameter,
an external 5 Amp Current Transformer (C.T.) must be used in
conjunction with a CTS-20-005-AVG-001 or CTS-20-005-VFD-
001 as shown in Fig. 5.

Latch Operation (Split Core Models)
Pressing down on the two (2) side tabs and swinging the cover
open, opens the split core current switch as shown in Fig. 6.
Lifting up the latch with a flat-tip screwdriver as shown in Fig. 7
can also open the unit. Press down firmly on the cover to close
the current switch. An audible “click” will be heard as the tab
slides over the tongue on the base.
CAUTION
Mating surfaces of the magnetic core are exposed
when the sensor is open. Silicone grease, present
on the cores to prevent rust, can capture grit and
dirt if care is not exercised. Operation can be
impaired if anything prevents good contact
between pole pieces. Visually check the mating
parts of the core before closing the current sensor.
