Moving Due to Inertia

• A mechanical lock is applied automatically when the Operation

Key is inserted. A high level of safety is achieved using a

mechanism where the lock is only released when voltage is

applied to the solenoid.

• Conforms to EN (TÜV) standards corresponding to the CE

marking.

• Certified by UL, CSA and CCC standards.

• The Switch contact is opened by a direct opening mechanism

(NC contacts only) when the protective cover is opened.

Direct opening mechanism that is EN-certified is indicated by

on the Switch.

• Auxiliary release key ensures easy maintenance and unlocks the

door in the case of a power failure.

• Tough aluminum die-cast body incorporating a switch box with

degree of protection satisfying IP67, UL, and CSA TYPE6P, 13.

• Equipped with a horizontal and vertical conduit opening.

• Models incorporating easy-to-see indicators for monitoring and

those using an adjustable Operation Key for a swinging door are

available.

• The mounting direction of the head can be changed

to allow the Operation Key to be inserted from four

directions.

D4BL Circuit Connection Example • Terminals 11 and 32 are connected internally and so connect terminals 12 and 31 for safety-circuit input. (GS-ET-19). • When using indicators, connect them to the auxiliary circuit side (monitor circuit) or in parallel between E1 and E2 as shown below. • Do not connect the indicators in parallel with the direct opening contact. If the indicators are broken, a short-circuit current may flow, causing equipment to malfunction. • The 24 VDC solenoid terminals have polarity.

D4BL Safety Precautions ● Be sure to read the precautions for all D4BL models in the website at: http://www.ia.omron.com/. Precautions for Correct Use DANGER Injury may occasionally occur. Always check to make sure that the safety functions operate correctly before using the machine. The safety functions may not operate correctly because of wiring mistakes, setting mistakes, or Switch malfunction, causing some machines to continue operating in situations where they should be stopped.
PAGE 14
D4BL Solenoid Lock Models Head Direction The solenoid lock locks the door only when power is supplied to the solenoid. Therefore, the door will be unlocked if the power supply to the solenoid stops. Therefore, do not use solenoid lock models for machines that may be operating and dangerous even after the machine stops operating. Switch and Operation Key Mounting Use four M5 screws and spring washers to mount the Switch and Operation Key, and tighten the screws to a suitable torque.

D4BL Processing and Connecting Cable/ Conduit Cable Connection Example 1. Connect the wires to the terminals in the order shown below for wiring efficiency. • The following procedures are recommended for mounting and wiring the indicator unit securely. • To ensure IP67, use OMRON’s SC-@M and Nippon Flex’s ABS-08Pg13.5 and ABS-12 Pg13.5 Connectors. • Recommended cable: UL2464-type cable that is AWG20 to AWG18 (0.5 to 1.
