(3) Resetting the low temperature
alarm tolerance setting
This unique function alerts the operator when
the sensed temperature drops below a set li mit.
Should this occur, an error message |H-^| will
be displayed, and the buzzer will sound con-
tinuously. When the temperature returns within
the allowable range, the buzzer will stop. The
value is stored in the FM-202 as described be-
low;
EXAMPLE:
If the set temperature is 650°F and the low temperature
alarm is 100°F, the alarm will trip when the sensed tem¬
perature goes below 550°F. _____
NOTE:
The threshold limits are: 30 -150°C; 60 - 300®F.
If a value outside these limits should be entered. the sys¬
tem will revert to the beginning of the mode. the hundreds
digit will flash, and the procedure must be restarted.
1. When the station enters low-temperature
alarm tolerance setting mode, the hundreds
digit begun flashing. Enter and store the
value in the same manner as described on
page 7 “Changing the temperature setting.”
2. If you enter a value exceeding the allowable
range shown to the left, you will be brought
