TECH TIPS
On low current loads, wrap sensor
multiple times to increase sensi-
tivity
CAUTION
Do not exceed sensor
maximum current. The
current detected by the
sensor will increase 1X with
each wrap.
MISE EN GARDE
Ne dépassez pas le courant maximal du capteur.
Le courant détecté par le capteur augmentera
1 fois à chaque tour.
To monitor loads greater than the current sensor maxi-
mum rating
Use a properly rated 5A CT as
shown below
Pour surveiller les charges
supérieures à la valeur
maximale du capteur de courant
Utilisez un CT 5 A avec la tension
nominale appropriée comme
indiqué ci-dessous.
CAUTION
5A CTs can present hazardous voltages. Install
CTs in accordance with manufacturers
instructions. Terminate the CT secondary wiring
before energizing primary conductor.
MISE EN GARDE
Les tensions des CT 5 A peuvent présenter des
dangers. Installez les CT en suivant les
instructions du fabricant. Terminez le câblage
secondaire du CT avant d'alimenter le
conducteur principal.

Sensor
Output
The CSP-NO-F-200A output changes state whenever
current above 0.35A is present; THE CS-NO-F-50A output
changes state above 0.25A. This provides "go/no" status
on loads that are not subject to mechanical failures.
Typical on/off status applications include:
• Lighting circuits
• Heater elements
• Direct drive fans (e.g. exhaust fans)
• Process motors
