4-2-1 How to Replace the Relay Output Terminal Block
Loosen the two terminal block replacement screws and pull the terminal block upwards. To install the new
terminal block, tighten the two terminal block replacement screws after attaching the terminal block and the
SL-R11. (The recommended tightening torque is 0.4 N•m.)
WARNING
• Always turn off the power supply when performing electrical wiring.
• The two control outputs (FSDs) provided in the SL-R11 must both be used to
build a safety system. Building a safety system with just one of these outputs
could cause the system not to stop due to a control output malfunction, which
could result in a serious accident, including serious injury or death to the ma-
chine operator.
• The AUX relay output provided in the SL-R11 is not an output for the safety
system, so it cannot be used as a control output (so called FSD) to stop the
machine. Using an AUX relay as an output relay is used to build a safety system
and stop the machine, could result in the serious injury or death.
• When wiring the SL-R11 output terminals to the control circuit of a machine
containing the SL-C, check with the machine manufacturer to make sure the
wiring is appropriate for the machine being used to ensure that the machine can
be stopped correctly. If the wiring is not done correctly for the machine, a serious
accident, such as serious injury or death to the machine operator could result.
• Follow electrical articles, regulations, standards, and laws for the country or
region in which the SL-R11 is being used when performing electrical wiring.
• Do not place cables or electrical lines used in wiring the SL-R11 in the same duct
as high-voltage electrical or power lines or in parallel with such lines.
