Max/Min. Alarm Diagram (minimum
and maximum temperature)
The maximum temperature alarm back swing occurs when the probe temperature is:
(1) lower than or equal to HAL - AFd
if Att=Ab(solute)
(2) lower than or equal to set + HAL- AFd
if Att=rE(lative)
The minimum temperature alarm back swing occurs when the probe temperature is:
(1) higher than or equal to LAL + AFd
if Att=Ab(solute)
(2) greater than or equal to set + LAL + AFd
if Att=rE(lative)
* (set -|LAL|+AFd)
The maximum temperature alarm occurs
when the probe temperature is:
(1) higher than or equal to HAL if
Att=Ab(solute)
(2) higher than or equal to Set + HAL if
Att=rEl(ative)
• if Att=Abs(olute) HAL must be with a
sign;
• if Att=rEL(ative) HAL must be only
positive.
The minimum temperature alarm occurs
when the probe temperature is:
(1) lower than or equal to LAL if
Att=Ab(solute)
(2) lower than or equal to Set + LAL if
Att=rEl(ative)
• if Att=Abs(olute) LAL must be with a
sign;
• if Att=rEL(ative) LAL must be only pos-
itive.
*NOTE: if Att=rEL(ative) LAL must be negative: therefore set point+LAL<set point because
set+(-|LAL|)=set-|LAL|
