Use terminals A and B to switch reset mode. A to B open: Manual reset A to B closed: Auto-reset. Use terminal T with + common -channel input. When using T, make sure that T and T are open. For -channel input, make sure T and T are closed.. With 00 to 0-VAC type, be sure to connect PE to a protective ground. With -VAC/VDC type, if the power supply is not connected to a protective ground, be sure to connect PE to a protective ground.. With -VAC/VDC type, the power supply terminals A and A have polarities. A is the negative pole.
J EXTERNAL CONNECTIONS
Precautions J WIRING Turn OFF the G9SA before wiring the G9SA to avoid electrical shock. Do not touch the terminals of the G9SA while the power is turned ON because the terminals are charged. Use the following to wire the G9SA. Stranded wire: 0.7 to. mm to 8 AWG Solid wire:.0 to. mm to 8 AWG Tighten each screw to a torque of 0.78 to.8 NSm (8 to kgfscm), or the G9SA may malfunction or generate heat. External inputs connected to T and T or T and T of the G9SA-0 must be no-voltage contact inputs. PE is a ground terminal. When a machine is grounded at the positive, the PE terminal should not be grounded. J MOUNTING EXPANSION UNITS Turn OFF the G9SA before connecting the Expansion Unit. When an Expansion Unit is being used, remove the connector cover from the G9SA Safety Relay Unit (G9SA-0, G9SA-0, or G9SA-j), and insert the connector of the Expansion Unit s connector cable. J APPLICABLE SAFETY CATEGORY (EN9-) All G9SA-series Relays meet the requirements of Safety Category of the EN9- standards when they are used as shown in the examples provided by OMRON. The Relays may not meet the standards in some operating conditions. The OFF-delay output of models G9SA--Tj and EX0-Tj, however, conform to Safety Category. The applicable safety category is determined from the whole safety control system. Make sure that the whole safety control system meets EN9- requirements. J MOUNTING MULTIPLE UNITS When mounting multiple Units close to each other, the rated current will be A. Do not apply a current higher than A. J CONNECTING INPUTS If using multiple G9SA models, inputs cannot be made using the same switch. This is also true for other input terminals. G9SA G9SA J EARTH SHORT A positive thermistor is built into the G9SA s, so you can detect earth short breakdowns and breakdown shorts between channel and channel. If the short breakdown is canceled, reset is automatic. J MANUAL RESTART MODE Always use NO (normally open) contacts for your reset switch, as shown in the application examples.
