Limit (Alarm Setpoint), Deadband (1)
Specify up to 4 setpoints in engineering unit within the Input Range. Alarms are reset when the signal goes out of the
alarm zone by the preset deadband values.
If you set only “High” and “Low” setpoints, they must be set immediately next to the “Normal” zone.
Deadband is used to avoid the alarm ON and OFF quickly and repeatedly around the setpoint when the input signal
changes that way. The alarm, once triggered, does not reset until the signal passes the point by the preset deadband.
‘e’ can be used to input an exponential value such as ‘1e9.’ Entering ‘e’ in any other way (e.g. ‘1ee’) will not be recog-
nized as a numeral.
Limit / Deadband
Max. 6 digits including a decimal point and minus sign
Normal Zone (2)
Specify the zone of normal status. When the input signal is out of this zone, the alarm indicator of the pen flashes.
Choose among Zone 0, 1, 2, 3 and 4.
Zone Color (3)
You can apply specific colors to represent each zone divided by the limits for use in the Display views. Touch the cur-
rent selection and use the color palette.
Alarm Output (4)
Set Enable to provide an external contact output at the alarm terminal. When multiple alarm outputs are set including
error output, the alarm contact turns ON/OFF by OR logic.
Relay (5)
Specify the zone(s) in which you wish the contact to be turned on or off.
The keys are arranged from the left to right in the order of Zone numbers (Zone 0 for the leftmost key, Zone 4 for the
rightmost key).
Alarm Message (6)...(9)
Set Enable to the thresholds where Messages are to be displayed on the Alarm History.
Up messages appear when the signal goes across an alarm setpoint upward. For example, Up message (0-1) is
sent when the signal goes over the Limit 1. Down messages appear when the signal goes across an alarm setpoint
downward. For example, Down message (0-1) is sent when the signal goes below the Limit 1. Message contents up
to 10 characters respectively for Up and Down.
