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 po wer 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 pr op er ty,
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. T out cont act
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.

5. Calibrate Model CSD-CA1G0-1 (see Setup and
Adjustments).

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.)

If the measured current is too low to be detected or
is higher than the maximum current rating of the
CSD, use the following methods to increase or
decrease current.
