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.
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.
Installation
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.

Mounting
1.Using the two screws (included), attach the mounting bracket to the back of the electrical enclosure.
2.Snap the CSD into place on the mounting bracket.
Wiring
1.Disconnect power to the conductor cable from the power source.
2.Snap the split core around the power conductor cable, and close the core until the core snaps shut.
Note: The switch contacts are solid state and they work just like dry contacts. When the switch is closed, less than 1 ohm is present; when the switch is open, more than 1 megohm is present.
3.Wire CSD output terminals to the control box Digital Input (DI) terminal (30 V maximum terminal voltage).
4.Reconnect the power conductor cable. (For wiring example, see Figure 2 and Figure 3.)
5.Calibrate Model CSD-CA1G0-1 (see Setup and Adjustments).
