● Designing
Load Relay Contact
If E3G is connected to a load with contacts that spark when the load
is turned OFF (e.g., a contactor or valve), the normally-closed side
may be turned ON before the normally-open side is turned OFF or
vice-versa. If both normally-open output and normally-closed output
are used simultaneously, apply an surge suppressor to the load.
Refer to OMRON’s PCB Relays Catalog (X33) for typical examples of
surge suppressors.
● Wiring
Connecting and Wiring
The E3G has a built-in function to protect the E3G from load
shortcircuiting. If load shortcircuiting results, the output will be turned
OFF. In that case, check the wiring and turn ON the E3G again so that
the short-circuit protection circuit will be reset. This function will
operate if the output current flow is at least 2.0 times the rated load
current. If a capacitive load is connected to the E3G, make sure that
the inrush current does not exceed 1.2 times the rated load current.
● Mounting
Mounting Conditions
● Water Resistance
Tighten the operation cover screws and terminal block cover screws
to a torque of 0.3 to 0.5 N·m in order to ensure water resistivity.
