Alarm Setpoint 1
SP-1
Defines the alarm setpoint for Alarm 1 in display units.
SP-2 SP-3
Hysteresis 1
hY-1
Specifies the size of a band around an Alarm Setpoint within
which the measured value may fluctuate without the alarm state changing.
It is in the same engineering units as the displayed value and the Setpoint.
The hysteresis value defines both the on and oFF hysteresis.
on hysteresis: For a high alarm it is the value (in engineering units) above
the setpoint beyond which the alarm is turned on. For a low alarm, it is the
measured value below the setpoint beyond which the alarm is turned on.
oFF hysteresis: For a high alarm it is the value (in engineering units)
below the setpoint beyond which the alarm is turned off. For a low alarm,
it is the measured value above the setpoint beyond which the alarm is
turned off.
The default hysteresis value for all alarms is 0.1.
hY-2 hY-3
Relay 1
rEL1
Defines the operation of Relay 1, which can be in either the
energised alarm state (truE) or the de-energised alarm state (FLSE).
rEL2 rEL3
A100
A100
Defines the display value which corresponds to 20mA or 10V
from the optional analogue retransmission.
A0
A0
Defines the display value which corresponds to 4mA or 0V from
the optional analogue retransmission.
