T
he Series CCS Current Switches are ideal for monitoring the operating status of
f
ans, pumps, and motors. These self-powered switches can be hung or tied directly
to cables or wires. For use on existing installations, split core models can be
installed without disconnecting cables. LED indicators provide a visual
confirmation that the current is flowing through the core. Both fixed and adjustable
set points are available. The adjustable models utilize a potentiometer to easily
a
djust the set point.
O
PERATING INSTRUCTIONS
The Series CCS Current Switches are intended to provide an
input to equipment under normal operating conditions. Where
failure or malfunction of the current switch 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 CCS.
RISK OF SHOCK
Disconnect power supply before making electrical connections.
Contact with components carrying hazardous voltage can
cause electrical shock and may result in severe personal injury or death.
INSTALLATION
MOUNTING
1. Mount the switch in a suitable location using the two mounting holes in the base
of the unit.
2. If using ties, make sure ties are securely fastened and that the unit is stable.
If using the provided screws, tightly screw in one screw at a time into each hole.
WIRING
1. Ensure that the power supply to the circuit is off.
2. For solid core devices: disconnect the circuit line, slide the power conductor
cable through the sensing hole of the current switch, and reconnect the circuit
line.
For split core devices: open the core using the release tab. Snap the core
closed around the power conductor cable. Make sure that the core release tab
is locked in its original position.
3. Connect the switch circuit to the two screw terminals using ring or fork type
terminals.
4. Turn circuit back on.
