4.0 SETUP
4.1 Alarm Set Point (Figure 4.1)
The alarm set point temperature is set by dip switch S2 as an integer. The switch setting
represents an eight bit binary number in degrees C with position 8 as the least significant bit
(LSB) and position 2 as the most significant bit (MSB). Position 1 is the sign bit.
An ‘open’ switch is a ‘1’ and ‘closed’ is a ‘0’.
If the desired set point is in degrees F, convert it to Celsius before proceeding.
Set the switches as follows:
1. Convert the desired set point temperature from degrees C to its eight bit binary equivalent
code. Table 4.1 is provided to convert F to C and the equivalent eight bit binary code.
2. Set S1-
1 ‘closed’ and S1-2 ‘open’. The alarm temperature setting will be displayed in degrees
C.
NOTE: S1-1 determines whether C or F is displayed in both the measurement and alarm set
modes.
S1-2 will switch the display between the dew point and the Alarm Setting.
3. Set S2, positions 1 through 8 according to the eight bit binary number determined in step 1. A
‘1’ is ‘open’, and a ‘0’ is ‘closed’.
4. The display should now read the set point temperature in degrees Celsius.
5. If Fahrenheit units are desired, set S1-
1 to ‘open’.
6. Return to dew point display by setting S1-
2 ‘closed’.
