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.
A relay output contact WILL NOT be disarmed as long as:
A relay output contact WILL NOT be disarmed if it is latched (and not yet
reset).
A relay output contact WILL NOT be disarmed as long as a running
t-OFF-delay timer is not yet expired (hold time of a relay output contact).
If the Disarm Control is not set to active.
If the Direct Command is not applied.
