The BIAS Setpt Temperature Variables (Var14 through
Var25)
The below listed BIAS Setpts set the temperature difference
(or deviation) at which a left-side temperature sensor triggers a
BIAS Setpt ‘Yellow_Alarm’ if it exceeds its right-side companion
sensor by the left-side BIAS Setpt amount.
And likewise vice-versa if a right-side sensor exceeds its left-side
companion sensor by the right-side BIAS Setpt amount.
Each sensor input has its own BIAS Setpt, with range 0000 to
9999.
 A BIAS Setpt = 0000 enables the Analog Input, but disables
its BIAS Alarm “Left-side sensor vs. Right-side sensor”
comparison feature.
 A BIAS Setpt between 0001 and 0998 enables the Analog
Input, and enables its BIAS Alarm feature by giving it the
desired temperature deviation SetPt value.
 A BIAS Setpt = 0999 disables an Analog Input completely
by turning ‘OFF’ that particular temperature sensor’s input
and its effects on the temperature alarms. The sensor’s 3-
digit LED display then shows ‘OFF”.
Note: Even though the BIAS setpts accept up to 0998 degrees,
typical ESI sensors only run up to 248 degrees.
The BIAS Setpts are in Var14 through Var25 , and all have a
factory default of 0000, which enables all analog inputs, but
which disables their BIAS alarm feature.
The left-side/right-side BIAS ‘companion’ pairs are listed
below with their associated analog input, UserVar variable, and
nomanclature.
Input # Variable Nomanclature
1 Var14 Head Bearing Left BIAS SetPt
2 Var15 Head Bearing Right BIAS SetPt
3 Var16 Head Rub Block Left BIAS SetPt
4 Var17 Head Rub Block Right BIAS SetPt
5 Var18 Knee Bearing Left BIAS SetPt
6 Var19 Knee Bearing Right BIAS SetPt
7 Var20 Knee Rub Block Left BIAS SetPt
8 Var21 KneeRub Block Right BIAS SetPt
9 Var22 Tail Bearing Left BIAS SetPt
10 Var23 Tail Bearing Right BIAS SetPt
11 Var24 Tail Rub Block Left BIAS SetPt
12 Var25 Tail Rub Block Right BIAS SetPt
13 Var26 Unused / Reserved
14 Var27 Unused / Reserved
15 Var28 Unused / Reserved
16 Var29 Unused / Reserved
When a BIAS Setpt’s deviation value is exceeded, it gives an
alarm by turning ON the corresponding temperature display’s
discrete Yellow-LED, plus putting the Yellow-Lightstack-Relay
/ Speed-Temperature-Warning-Relay / Horn-Relay, all into their
alarm states.
Also, once a sensor goes into a BIAS Setpt ‘Yellow_Alarm’,
its 3-digit LED display ‘Latches’ the highest value reached. To
‘clear’ the latched BIAS Setpt ‘Yellow_Alarm’ the user must give
a ‘Silence_Horn/Alarm_RESET’ command to the ES1 once the
temperature has dropped below the BIAS setpt. (See Operations
Notes Section “How to Clear Alarms” for details).
Var30.
Temperature_Display_Select. (Temperature in Fº
Fahrenheit or Cº Celsius).
The
Var30
range is limited to these below listed choices:
 ‘0000’ = display temperatures in Fº Fahrenheit.
 ‘0001’ = display temperatures in Cº Celsius.
Note: If you setup your ES1 to display temperatures in
Fahrenheit Fº and have your temperature setpts in Fº, and
then later change
Var30
to Celsius Cº, the ES1 does NOT
automatically convert the setpts over to equivilent Cº
values, (or vice versa Cº to Fº)
Factory default for Var30 is 0000 for degrees Fahrenheit
.
