PROGRAMMING EXAMPLE
As an example of a programming sequence, the following values, gained from
a temperature-time monitoring application, are programmed into the indicator.
DISPLAY: Display the actual temperature of a liquid solution in °F.
Activate alarm #1 output when temperature falls below 25°F, activate display
alarm. Peak and valley
(max/min)
readings for each cycle to be recorded.
TOTALIZER: When total exceeds 30,000 degree-minutes then latch alarm
#2 which stops the heating process and sounds a process complete bell.
Reset alarm #2 by remote input. Disable totalization when temperature
falls below 250°F. Reset the total from the front panel. Switch the display
from/to temperature and total.
SERIAL: Provide hardcopy printout of total, input and peak/valley when
operator actuates print request. Baud rate 300.
ANALOG RE-TRANSMISSION: Record temperature profile. 4 mA at
100°F and 20 mA at 400°F.
