Operation
The CSR command relay attaches to the side of any full-
size CS type sensor or switch and adds a form C relay
function. It provides line voltage switching with control
either from an automation system digital output or from a
CS-610-200 or CS-GnG-200 current switch. A status LED
indicates the relay state and the relay output features both a
normally-open and a normally-closed contact.
The CSR/CS combination provides a convenient solution
when status indication and motor control are needed at a
single location. The CSR can accept a digital control signal
from the controller to activate the relay contacts which can
be used to provide power to the motor contactor to start the
motor. The CS switch will then provide a digital proof-of-
flow signal to the controller to indicate motor status.

death or serious injury.
Installation
- Read all warnings before beginning
- Ensure the selected device has the correct ratings
- Disconnect and lock out power
- Snap the CSR device onto the side of a CS product
- Mount the CS switch with two screws through the base or
snap onto a standard DIN mounting rail
- Place the monitored conductor through the sensor hole
- Wire the status output to the controller as shown in the
wiring diagrams (not polarity sensitive)
- Wire the coil input to the controller or status switch as
required
- Wire the relay contacts to the load as required
- Reconnect the power
