Applications

The Current Switch Device (CSD) Series of digital

output switches are nonintrusive devices designed to

detect current flowing through a cable or wire. A cost

effective solution for monitoring on and off status or

proof of operation, these units are ideal for monitoring

small current loads on motors driving fans and blowers,

heating coils, and lighting.

These units provide a universal solid state output and

do not require a power supply. Completely

self-powered, these units draw their power from current

induced from the monitored cable or line.

Installation

IMPORTANT: The Current Switch Device (CSD)

Series Current Devices are intended to provide an

input to equipment under normal operating

conditions. Where failure or malfunction of the CSD

could lead to personal injury or property damage to

the controlled equipment or other property,

additional precautions must be designed into the

control system. Incorporate and maintain other

devices, such as supervisory or alarm systems or

safety or limit controls, intended to warn of or protect

against failure or malfunction of the CSD.

IMPORTANT : Le Current Switch Device (CSD)

Series Current Devices est destiné à transmettre

des données entrantes à un équipement dans des

conditions normales de fonctionnement. Lorsqu'une

défaillance ou un dysfonctionnement du CSD risque

de provoquer des blessures ou d'endommager

l'équipement contrôlé ou un autre équipement, la

conception du système de contrôle doit intégrer des

dispositifs de protection supplémentaires. Veiller

dans ce cas à intégrer de façon permanente

d'autres dispositifs, tels que des systèmes de

supervision ou d'alarme, ou des dispositifs de

sécurité ou de limitation, ayant une fonction

d'avertissement ou de protection en cas de

défaillance ou de dysfonctionnement du CSD.

IMPORTANT: Install the CSD Series Current

Devices only on the input side of a variable speed

drive. Otherwise excessive wear may occur on the

controlled equipment, as well as premature failure of

the CSD Series Current Devices.

WARNING: Risk of Electric Shock.

Disconnect the power supply before

making electrical connections. Contact with

components carrying hazardous voltage

can cause electric shock and may result in

severe personal injury or death.

AVERTISSEMENT : Risque de

décharge électrique.

Débrancher l'alimentation avant de réaliser

tout branchement électrique. Tout contact

avec des composants conducteurs de

tensions dangereuses risque d'entraîner

une décharge électrique et de provoquer

des blessures graves, voire mortelles.

WARNING: Risk of Personal Injury.

Do not touch the relay while power is

applied to the relay. The relay surface is

hot during use, and may cause a serious

burn upon contact.

AVERTISSEMENT : Risque de

blessure.

Ne pas toucher le relais lorsque le relais

est sous tension. La surface du relais

devient extrêmement chaude durant son

utilisation et risque de provoquer des

brûlures graves en cas de contact.

If Measured Current Is Too Low to Be Detected Setup and Adjustments Wrap the conductor (wire) through the sensing hole and around the CSD body to produce multiple turns to increase the measured current. Measured current = actual current times the number of turns (see Figure 4). Calibration Position the CSD so the status output panel faces you. Confirm the monitored load (for example, a motor or heater) is running, and use the following methods to calibrate the CSD.
