Circuit Connection Example
(Examples for the D4JL-
@
NF
@
-
@
)
• Terminals 11-42 and terminals 21-52 are connected internally and
so connect terminals 12-41 and 22-51 for safety-circuit input. (GS-
ET-19).
• Direct opening contacts used as safety-circuit input are indicated
with the
mark. Terminals 11-12 and terminals 21-22 are direct
opening contacts.
• Do not connect the indicator directly to direct opening contacts. If
indicator is connected in parallel with direct opening contacts, a
short-circuit current may flow in the event that the indicator is
damaged, causing equipment to malfunction.
• Do not switch standard loads for more than 2 circuits at the same
time. Otherwise, the level of insulation may decrease.
• The solenoid terminals have polarity (E1: + and E2:
−
). Confirm the
polarity before wiring.

Contact Forms
Indicates conditions where the Key is inserted and the lock is applied. Terminals 42-11 and terminals 52-21 are connected internally (as per BIA
GS-ET-19).
