Circuit Connection Example
• Terminals 12 and 41 are connected internally and so connect termi-
nals 11 and 42 for safety-circuit input. (BIA GS-ET-19)
• Connect terminals 21 and 22 and terminals 51 and 52 in series
when using as safety-circuit input (redundancy circuit for terminals
11 and 12 and terminals 41 and 42 above). Connect the terminals
individually when using as auxiliary-circuit input (e.g., terminals 21
and 22 for safety-door open/closed monitoring and terminals 51
and 52 for monitoring the lock status).
• In the following connection example, terminals 21 and 22 and ter-
minals 51 and 52 are used as auxiliary-circuit input.

• Direct opening contacts used as safety-circuit input are indicated
with the mark. Terminals 11 and 12 and terminals 21 and 22
are direct opening contacts.
• Connect the indicators in parallel to the auxiliary circuits or termi-
nals E1 and E2.
• Although the 3 lines are connected at the time of delivery, rewire
them as necessary for the application.
• The following table shows the connection configuration required to
make the green indicator light when the door is closed and the
orange indicator light when the solenoid turns ON.

• If an indicator is connected in parallel to a direct opening contact,
when the indicator breaks, a short-circuit current will be generated,
possibly resulting in an installation malfunction.
• Do not switch standard loads for more than 2 circuits at the same
time. Otherwise, the level of insulation may decrease.
• The solenoid has polarity. Be sure to connect terminals with the
correct polarity.
