Programming
The SZ1143b may be programmed through the display
and keypad, or with a PC.
If programming with a PC, the following must be set
through the keypad prior to programming:
• Address (step #2)
• Baud rate (step #3)
For more information on programming through the PC,
consult your TCS software manual.

To access the programming screens, press both the
“Scroll” and “Next” keys simultaneously.
Scroll Key
- The "Scroll" key is also used to
save any changes to the "current" screen and
advance to the next screen while program-
ming. The "Scroll" key is used to enter the
Programming Mode when pressed with the
"Next" key.
Next Key
- Used to enter Programming Mode
when pressed with the “Scroll” key. Also used to
exit programming without saving changes to the
current screen. In monitoring mode, the “Next” key is used
to scroll backwards.
Increment/decrement Keys
- Used to select
the desired value.
Main Monitoring Screen.
Press the
scroll and next buttons to access the fol-
lowing screens.
Access Code Entry Screen.
Enter
the access code. If the wrong code is
entered, the program reverts to the main
screen. 248 is the default access code.
Controller Address Screen.
If using a
PC to access the SZ1143b, set a unique
address from 0 to 255, excluding 248.
Communication Baud Rate Screen.
If
using a PC to access the SZ1143b, all
controllers on a network must be set to
the same baud rate. Choose between
2.4K, 4.8K, 9.6K and 19.2K.
Enable high/Low.
Select yes to enable
High/Low control.
high/Low output Screen.
Select
whether you would like to pass the low
or the high analog inout (This screen
only appears if High/Low Control mode
is enabled).
Analog output Range Screen.
Choose
whether the analog output range will be
0-20mA or 4-20mA. (This screen is the
last screen if High/Low control mode is
enabled, and is the same as step 22
when not enabled).
Enable dew Point Control.
Select yes
to enable dew point control. (Skip to step
14 if dew point is selected.)
AI1 Low Limit Span Screen.
Enter the
lowest value of the span range of the
transmitter connected to AI1 (i.e., value
at 4mA). Note: Automatically set to 0 if
dew point control is selected.
AI1 high Limit Span Screen.
Enter the
highest value of the span range of the
transmitter connected to AI1 (i.e., value
at 20mA). Note: Automatically set to 100
if dew point control is selected.
AI2 Low Limit Span Screen.
Enter the
lowest value of the span range of the
transmitter connected to AI2 (i.e., value
at 4mA). Note: Automatically set to 0 if
dew point control is selected.
AI2 high Limit Span Screen.
Enter the
highest value of the span range of the
transmitter connected to AI2 (i.e., value
at 20mA). Note: Automatically set to 100
if dew point control is selected.
AI1 decimal Point Screen.
For display
purposes, the SZ1143b allows a deci-
mal point to be turned on. No scaling
is done. Enter "0" for no decimal point,
"XX.X" for a decimal point in the tenths
position, "X.XX" for a decimal point in
the hundredth position or ".XXX" for a
decimal point in the thousandths posi-
tion.
