CS-625 Series Current Switch
Installation Instructions
Introduction
The CS-625 current switch is a solid-state switch that monitors
line current for electrical loads such as pumps, conveyors,
machine tools or fans and closes the output contacts when
the adjustable trip point is exceeded. It is typically used to
monitor motor operation and can be used to determine
on/oꢀ status, proof of operation, motor failure or belt loss.
The sensor requires no external power as it is totally powered
by induction from the primary AC line being monitored. The
trip setpoint is adjustable in three jumper-selectable ranges
from a minimum value (1 Amp) up to 175 Amps by rotating
the adjustment pot counter-clockwise.
The output contacts can switch loads up to 1 Amp 240 Vac.
**** WARNING ****
- Electric Shock Hazard, Use Caution
- Disconnect and lock out power before installation
- Follow national and local electrical codes
Installation
-Ensure the selected device has the correct ratings for
application
-Set the range jumper to the desired range. (See Figure 1)
-Mount the sensor with two screws through the base .
- Read and understand these instructions before installing
- Installation only by qualiꢁed electrical personnel
- Do not rely on this device to indicate line power
- Only install this device on insulated conductors
- Only install on 600 Vac maximum conductors
- Do not use this device for life-safety applications
- Do not install in hazardous or classiꢁed locations
- Install this product in a suitable electrical enclosure
- Failure to follow these instructions may result in
serious injury or death.
-Read all warnings before beginning
The base has an integral mounting tab to allow screw
mount to a surface.
If predrilling is required, the actual device may be used to mark holes. The
mounting holes in the base will accommodate up to a #10 size screw (Not
supplied) . See Figure 2
Figure 3
Place the monitored conductor through the sensor hole and reconnect. See
Figure 3.
-The CS-625 is not polarity sensitive. Use shielded wiring for all connections and
do not locate the device wires in the same conduit with wiring used to supply
inductive loads such as motors. Make all connections in accordance with national
and local codes.
-Reconnect the power
