3) How to set-up your Electro-Sentry 1 for
Temperature Monitoring:
A)
The application’s Temperature sensors are typically
connected to the Electro-Sentry 1’s 4-20 mA
Analog Inputs as follows:
Terminal
Block
Analog
Input # Description
TB1 1 Head Bearing Left
TB2 2 Head Bearing Right
TB3 3 Head Rub Block Left
TB4 4 Head Rub Block Right
TB5 5 Knee Bearing Left
TB6 6 Knee Bearing Right
TB7 7 Knee Rub Block Left
TB8 8 Knee Rub Block Right
TB9 9 Tail Bearing Left
TB10 10 Tail Bearing Right
TB11 11 Tail Rub Block Left
TB12 12 Tail Rub Block Right
For the TB1 through TB12 terminal blocks:
Pin1 = +24Vout_A, Pin 2 = 4-20 mA Signal Input,
Pin 3 = Gnd_A
.
B)
All 12 Analog Inputs can be setup for sensors
having a Temperature proportional 4-20mA output.
Six Analog Inputs can also be setup for sensors
having a Contact Closure output, as shown in the
following table.

TB1 1 Yes No N.A.
TB2 2 Yes No N.A.
TB3 3 Yes Yes See Var11
TB4 4 Yes Yes See Var11
TB5 5 Yes No N.A.
TB6 6 Yes No N.A.
TB7 7 Yes Yes See Var11
TB8 8 Yes Yes See Var11
TB9 9 Yes No N.A.
TB10 10 Yes No N.A.
TB11 11 Yes Yes See Var11
TB12 12 Yes Yes See Var11
If your application uses Contact-Closure sensors for Rub
Blocks, etc, then see page 3 of the Reference portion
of the User Manual for details on how to setup
Var11.
Note
4
: Factory default for Var11 is 0000, for all
Analog Inputs are set for 4-20 mA
Temperature sensors.
C)
For those Analog Inputs that you are not using
(i.e., those Analog Inputs having no Temperature sensors
or no Contact-Closure sensors connected to them):
You must turn ‘OFF’ the effect of any unused Analog
Inputs by setting their BIAS Temperature Setpts to
‘
0999 ’. The BIAS Setpts are in Var14 through Var25 ,
and correspond to the 4-20 mA Analog Inputs as
follows:
Var# Description Default
Value
User’s
Value
14 Input #1 BIAS
Temperature SetPt. 0000
15 Input #2 BIAS
Temperature SetPt. 0000
16 Input #3 BIAS
Temperature SetPt. 0000
17 Input #4 BIAS
Temperature SetPt. 0000
18 Input #5 BIAS
Temperature SetPt. 0000
19 Input #6 BIAS
Temperature SetPt. 0000
20 Input #7 BIAS
Temperature SetPt. 0000
21 Input #8 BIAS
Temperature SetPt. 0000
22 Input #9 BIAS
Temperature SetPt. 0000
23 Input #10 BIAS
Temperature SetPt. 0000
24 Input #11 BIAS
Temperature SetPt. 0000
25 Input #12 BIAS
Temperature SetPt. 0000
The factory default settings for all the BIAS
Temperature Setpts Var14 through Var25 is 0000,
which enables all Analog Inputs, but which disables
their BIAS alarm feature.
(More details about the
BIAS alarm feature later).

What temperature scale do you want to use, Fº
Fahrenheit or Cº Celsius?
Set Var30 Temperature_Display_Select as needed.
