Section 2
The following Alarm Relay Setpoints are set in the same way as the two previously shown
examples by entering numeric values and storing the data.
Max LiquIdent
The [Max LiquIdent] menu cell stores the maximum range value for the LiquIdent function.
Min LiquIdent
The [Min Liquident] menu cell stores the minimum range value for the LiquIdent function.
High Viscosity cS
The [High Viscosity cS] menu cell sets the high liquid viscosity alarm relay setpoint. The
viscosity units are centistokes with no alternatives offered.
Low Viscosity cS
The [Low Viscosity cS] menu cell sets the low liquid viscosity alarm relay setpoint. The viscos-
ity units are centistokes with no alternatives offered.
High Temperature
The [High Temperature] menu cell sets the high temperature alarm relay setpoint. If metric
preferences are selected
prior to site creation
the temperature units will be in Centigrade. If
English preferences are selected
prior to site creation
the temperature units will be in Fahren-
heit.
Low Temperature
The [Low Temperature] menu cell sets the low temperature alarm relay setpoint If metric
preferences are selected
prior to site creation
the temperature units will be in Centigrade. If
English preferences are selected
prior to site creation
the temperature units will be in Fahren-
heit.
Interface Vs m/s
The [Interface Vs m/s] menu cell sets the Interface Vs alarm relay setpoint. Relay changes
state when variable exceeds users setpoint.
Aeration %
The 1010PVN surpasses all other transit-time systems in its ability to operate with substan-
tial aeration (caused by entrained gases, mixing condition or cavitation). Some applications
may require an alarm indication if aeration exceeds a particular level. The meter detects this
aeration level and provides this data as an output. The aeration percentage triggers the alarm
relay whenever it meets or exceeds the threshold you set in this menu cell. The aeration
percentage (Vaer %) appears in the [Liquid Data] menu cell of the Diagnostic Data Menu. The
digital display screen also shows the current aeration percentage.
NOTE: Severely aerated conditions may induce meter fault. The 50% default usually
allows enough leeway for continued operation. For intermittent faults, see
memory interval in the Output Control menu.
