S1 MinOn and S2 MinOn
The S1 Minimum ON Time and S2 Mini-
mum ON Time parameters set the amount of
time a sensor control output must remain ON
after activating before being allowed to turn
OFF. Enter the desired time in minutes.
S1 MinOFF and S2 MinOFF
The S1 Minimum OFF Time and S2 Mini-
mum OFF Time parameters set the amount of
time a sensor control output must remain OFF
after deactivating before being allowed to turn
ON. Enter the desired time in minutes.
8.2.10.3. Sensor Screen 3 (Hi/Lo Alarm)
S1 Hi Alarm and S2 Hi Alarm
The
S1 HiAlarm
and
S2 HiAlarm
fields set
the high alarm setpoint for the Sensor Control
applications. Whenever a sensor control input
rises above the Alarm Hi setpoint, an alarm will
be generated.
S1 Lo Alarm and S2 Lo Alarm
The
S1 LoAlarm
and
S2 LoAlarm
fields set
the low alarm setpoint for the Sensor Control
application. Whenever the sensor control input
falls below the low alarm setpoint, an alarm will
be generated in the parent E2 or Einstein.
Alarm Delay
The Alarm Delay for Sensor Control 1 and 2
(
S1
and
S2
) set the amount of time the sensor
control input must remain above the high alarm
setpoint or below the low alarm setpoint before
an alarm will be generated. Enter the desired
alarm delay in minutes.
8.2.10.4. Sensor Control Screen 4 (Alarm
Priority, Comb Method)
Alarm Priority
The Alarm Priority field determines the pri-
ority level of the high and low level alarms gen-
erated by this sensor control application. The
priority level is used by the parent E2 or Einstein
to determine how the alarm will be reported and
handled.
Comb Method
The Comb Method only applies if you
assigned more than one input to this Sensor Con-
trol application. When multiple inputs are being
used, they will be combined into a single input
value using the method chosen in this field.
There are five strategies to choose from:
•
AVG -
The average value of all case temperature in-
puts.
•
MIN -
The lowest sensor value of all the case tem-
perature inputs.
•
MAX -
The highest sensor value of all the case tem-
perature inputs.
•
MIX -
A mixture of two inputs, the ratio of which is
determined by the
Mix %
field. Mix will use the
Mix % for the Case Temp Combination under the
Setpoints screens (refer to
Mix Percentage
in
Sec-
tion 8.2.4.4., Comb Method
).
•
FIRST -
The lowest-numbered input that is not
shorted, open, or otherwise invalid, will be used as
the case temperature input. If you are not using more
than one input, set the
CombMethd
field to
First
.
