ALARMS (folder AL)
Att
HAL and LAL parameters mode, i.e. the absolute temperature value or differential in relation to the
setpoint. 0 = absolute value; 1 = relative value.
NOTE: In case of relative values (par. Att=1), the HAL parameter should be set to positive
values, while the LAL parameter should be set to negative values (-LAL).

HAL (!)
Maximum temperature alarm. Temperature value (intended either as distance from setpoint or as an absolute
value based on Att) which, if exceeded in an upward direction, triggers the activation of the alarm signal.
See “Max/Min temperature alarms”.
LAL to 320 °C/°F 50.0 50.0 8.0
LAL (!)
Minimum temperature alarm. Temperature value (intended as distance from setpoint or as an absolute
value based on Att) which, when exceeded downwards, triggers the activation of the alarm signal.
See “Max/Min temperature alarms”.
