DISPLAY
Display: 16 mm (.63) high, 4 ½ digits, 7-segment LED
Display range: -19999 to 19999
Decimal point position: 10–1, 10–2, 10–3, 10–4 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.
