Precautions

Correct Use

Relays with Forcibly Guided Contacts

Caution

While the Relay with Forcibly Guided Contacts has the previously

described forcibly guided contact structure, it is basically the same

as an ordinary relay in other respects. Rather than serving to prevent

malfunctions, the forcibly guided contact structure enables another

circuit to detect the condition following a contact weld or other mal-

function. Accordingly, when a contact weld occurs in a Relay with

Forcibly Guided Contacts, depending on the circuit configuration, the

power may not be interrupted, leaving the Relay in a potentially dan-

gerous condition (as shown in Fig. 1.)

To configure the power control circuit to interrupt the power when a

contact weld or other malfunction occurs, and to prevent restarting

until the problem has been eliminated, add another Relay with Forc-

ibly Guided Contacts or similar Relay in combination to provide

redundancy and a self-monitoring function to the circuit (as shown in

Fig. 2).

Do not touch the terminal area of the Relays or the socket terminal

area (charged area) while power is ON. Electric shock will result.

Relays with Forcibly Guided Contacts

A Relay with Forcibly Guided Contacts is a Relay with which a safety

category circuit can be configured.

Wiring

Use one of the following wires to connect to the P7SA-10F/10F-ND/

14F/14F-ND.

Stranded wire:0.75 to 1.5 mm²

Solid wire:1.0 to 1.5 mm²

Tighten each screw of the P7SA-10F/10F-ND/14F/14F-ND to a

torque of 0.98 N·m securely.

The G9S/G9SA Safety Relay Unit, which combines Relays such as

the Relay with Forcibly Guided Contacts in order to provide the

above-described functions, is available for this purpose. By connect-

ing a contactor with appropriate input and output to the Safety Relay

Unit, the circuit can be equipped with redundancy and a self-monitor-

ing function.

Wire the terminals correctly with no mistakes in coil polarity, other-

wise the G7SA will not operate.

Cleaning

The G7SA is not of enclosed construction. Therefore, do not wash

the G7SA with water or detergent.

Fig 1

Fig 2

Forcibly Guided Contacts (from EN50205)

If an NO contact becomes welded, all NC contacts will maintain a

minimum distance of 0.5 mm when the coil is not energized. Like-

wise if an NC contact becomes welded, all NO contacts will maintain

a minimum distance of 0.5 mm when the coil is energized.
