2. Check Using an Operation Test with the Machine Stopped
With the machine stopped, turn on the power of the SL-CHS and carry out the following tests using the
test piece included in the package. If the floating blanking function is active, do not use the attached
test piece, but use a proper test piece that conforms to the description given in the SL-R12EX manual.
❏
When the power of the SL-CHS is turned on with no test piece in the detection zone, the output
status indicator as well as bar LEDs turn green.
❏
Confirm that the status indicator (bar LED) on the SL-CHS turns red and maintains red state while
the test piece is present within the detection zone.
❏
The test piece can be detected regardless of its location as long as it is in the detection zone.
❏
If the SL-R11(E) restart interlock function is enabled, when the test piece is removed, confirm that
the bar LEDs on the SL-CHS light up green, the output status indicator lights up red, and the SL-
R11(E) interlock indicator lights up yellow.
❏
When in the restart interlock state, the start/restart input causes the output status indicator to
change to green, and the SL-R11(E) interlock indicator to turn off.
❏
If the SL-R11(E) start interlock function is enabled, confirm that the bar LEDs lights up green, the
output status indicator lights up red, and the SL-R11(E) interlock indicator lights up yellow when the
power of the SL-CHS is turned on with no object in the detection zone.
❏
In addition, the output status indicator changes to green and the SL-R11(E) interlock indicator turns
off when there is a start/restart input while in the start interlock state.
Move the test piece for detection confirmation as illustrated in the figure below.

3. Operation Test with the Machine Operating
This test confirms that the machine stops its operation.
❏
Place the test piece in the detection zone or protection zone of the SL-CHS. It is recommended to
try three locations: near the transmitter, near the receiver, and the central area of the detection
zone. The machine must stop immediately as soon as the test piece is placed.
❏
The machine must remain stopped as long as the test piece is in the detection zone.
❏
The machine will not operate when the SL-CHS Series power supply has been interrupted.
❏
The overall response time of the machine, including the response time of the SL-CHS and the time
it takes for the machine to stop, must be shorter than the overall response time T used in the
calculation of safety distances (
➮ See “2-2 Safety Distances” (page 2-5)).
