Sensor Fail Heat or Cool Output
When a sensor fail alarm occurs or when the OUTPUT
OVERRIDE DIG INPUT (page 77) becomes active on a loop
that is in automatic control, that loop goes to manual con-
trol at the percent power output set here.
Selectable values: 0 to 100%.
NOTE!
When a sensor fails or the override input is
detected, both the heat and cool outputs are
set to their fail settings. In most applications,
SENSOR FAIL HT OUTPUT and SENSOR
FAIL CL OUTPUT should be set to 0%.
WARNING!
Do not rely solely on the sensor fail alarm to
adjust the output in the event of a sensor fail-
ure. If the loop is in manual control when a
failed sensor alarm occurs, the output is not
adjusted. Install independent external safety
devices that will shut down the system if a
failure occurs.
Heat or Cool Thermocouple Break Output Average
If you set this parameter to ON and a thermocouple break
occurs, a loop set to automatic control status will go to man-
ual mode at a percentage equal to the average output prior
to the break.
Selectable range: ON or OFF
