3. Check Using an Operation Test with the Machine Stopped
With the machine stopped, turn on the power of the SL-CHG 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 at-
tached test piece, but use a proper test piece that conforms to the description given in the SL-R12EX
manual.
❏
The output status indicator (bar LED) on the SL-CHG turns red and stays red while the test piece is
present within the detection zone.
❏
When the power of the SL-CHG is turned on with no test piece in the detection zone, the output
status indicator as well as all eight bar LEDs turn green.
❏
The test piece can be detected regardless of its location as long as it is in the detection zone.
❏
If the SL-R11G restart interlock function is enabled, when the test piece is removed, confirm that
bar LEDs on the SL-CHG light up green, the output status indicator lights up red, and the SL-R11G
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-R11G interlock indicator to turn off.
❏
If the SL-R11G start interlock function is enabled, confirm that the bar LEDs light up green, the
output status indicator turns red, and the SL-R11G interlock indicator lights up yellow when the
power of the SL-CHG is turned on with no object in the detection zone.
❏
In addition, the output status indicator changes to green and the SL-R11G 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.

4. 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-CHG. 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 by the detection of the test piece.
❏
The machine must remain stopped as long as the test piece is in the detection zone.
❏
The machine will not operate when the SL-CHG Series power supply has been interrupted.
❏
The overall response time of the machine, including the response time of the SL-CHG 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 2-4)).
