RRTD 1 ALARM PKP DELAY
of 5 to 600 seconds differs from the existing RTD settings to correspond to the range of the RRTD unit.
RRTD 1 TRIP TEMPERATURE
differs from the existing RTD settings to correspond to the range of the RRTD unit.
RRTD 1 TRIP PKP DELAY
to 600 seconds differs from the existing RTD settings to correspond to the range of the RRTD unit.
RRTD 1 TRIP RST DELAY
RRTD 1 TRIP VOTING
element operates individually and no voting takes place.
A value of "Group" indicates that element is allowed to issue a trip if N – 1 of other RTDs of the same group pick up as well
(where N is the number of enabled RTDs from the group). For example, if three RTDs are assigned to the same group, there
needs to be at least one additional RTD of the same group picked up to issue a trip command.
The "Remote RTD 1" through "Remote RTD 12" values indicate that element is allowed to issue a trip if the corresponding
peer RTD is also picked up.
— This setting allows monitoring an open remote RTD sensor circuit. If this functionality is not required, then a
RRTD 1 OPEN
value of "None" disables monitoring and assertion of output operands. If set to "Alarm", the monitor sets an alarm when a
broken sensor is detected. If set to "Block", the monitor sets an alarm and simultaneously block remote RTD operation
when a broken sensor is detected.
If targets are enabled, a message appears on the display identifying the broken RTD. If this feature is used, it is
recommended that the alarm be programmed as latched so that intermittent RTDs are detected and corrective action can
be taken.
— This setting is used to block remote RTD operation.
