or none
Zero indication
: Higher-digit zeros are suppressed.
Over-range indication
: ‘-19999’ or ‘19999’ blinking for display values out of the scaled range.
‘S.ERR’ and ‘Max’ blinking when the input signal is out of the usable range.
Alarm status indication
LL indicator
: Green turns on when the LL alarm is tripped.
L indicator
: Green turns on when the L alarm is tripped.
H indicator
: Red turns on when the H alarm is tripped.
HH indicator
: Red turns on when the HH alarm is tripped.
P indicator
: Amber turns on when none of the other alarms is tripped.
Note: Only ‘P’ turns on with no-alarm-output type. ‘LL’ or ‘HH’ does not turn on with dual-alarm-output type.
All setpoints can be independently set either for Hi or Lo alarm trip.
