❏
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
the 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 lights up green, the
output status indicator lights up 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.

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-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 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-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)).
4. Test Results Confirmation
❏
If the SL-CHG or the machine to which the SL-CHG has been installed fails any part of the above
test, operation should be ceased until satisfactory test results are obtained.
❏
A record of the test results must be maintained.
WARNING
If the SL-CHG does not function as described in the test procedure, do not attempt
to operate the machine to which the SL-CHG has been installed. Such an operation
may lead to the serious harm, including a serious injury or death of the machine
operator.
