Forcing the Relay Output Contacts
The parameters, their defaults, and setting ranges have to be taken from Relay
Output Contacts section.
Principle – General Use
The User MUST ENSURE that the relay output contacts operate normally after
maintenance is completed. If the relay output contacts do not operate normally,
the protective device WILL NOT provide protection.
For commissioning purposes or for maintenance, relay output contacts can be set by force.
Within this mode [Service/Test Mode (Prot inhibit)/WARNING! Cont?/Force RO], relay output contacts can be set by
force:
Permanent; or
Via timeout.
If they are set with a timeout, they will keep their “Force Position” only as long as this timer runs. If the timer expires,
the relay will operate normally. If they are set as Permanent, they will keep the “Force Position” continuously.
There are two options available:
Forcing a single relay »
Force Rox«;
and
Forcing an entire group of relay output contacts »
Force all Outs«
.
Forcing an entire group takes precedence over forcing a single relay output contact!
A relay output contact WILL NOT follow a force command as long as it is
disarmed at the same time.
A relay output contact WILL follow a force command:
If it is not disarmed; and
If the Direct Command is applied to the relay(s).
Keep in mind, that forcing all relay output contacts (of the same assembly
group) takes precedence over the force command of a single relay output
contact.
