Disarming the Relay Output Contacts
The parameters, their defaults, and setting ranges have to be taken from
the Relay Output Contacts section.
Principle – General Use
Within this mode [Service/Test Mode (Prot inhibit)/WARNING! Cont?/DISARMED], entire groups of relay output
contacts can be disabled.
By means of this test mode, contact outputs switching actions of the relay output contacts
are prevented.
If the relay output contacts are disarmed, maintenance actions can be carried out without the risk of
taking entire processes off-line.
The User MUST ENSURE that the relay output contacts are ARMED AGAIN
after maintenance is complete.
If they are not armed, the protective device
WILL NOT provide protection.
Zone Interlocking Output and the Supervision Contact cannot be disarmed.
Within this mode [Service/Test Mode (Prot inhibit)/WARNING! Cont?/DISARMED] entire groups of relay output contacts
can be disarmed:
Permanent; or
Via timeout.
If they are set with a timeout, they will keep their “Disarm Position” only as long as this timer runs.
If the timer
expires,
the relay output contacts will operate normally.
If they are set Permanent, they will keep the “Disarm State”
continuously.
