4. CONFIGURATION
SUB-MATRIX PARAMETER CLASSIFICATION
ANALOG INPUT
BURNOUT
DEFINITION:
Allows you to define the safety backup position to activate alarms
(if configured) in case of sensor burnout. The trace can go either on the right
(high) or on the left (low).
HOW TO MODIFY IT:
Select new text.
POSSIBLE CHOICES:
NO BURNOUT: No burnout.
B OUT LOW: Burnout configured low scale. Display shows [-9999]
B OUT HIGH: Burnout configured high scale. Display shows [9999]
FIX LOW: Value fixed low. (mA) Not configurable
FIX HIGH: Value fixed high. (RTD/OHMS) Not configurable
FIX NONE: Undefined value. Not configurable
(Linear sensors)
0 to 10 V / - 5 to 5 V / -1 to 1 V / -500 to 500 mV
NOTE:
- For some sensors (mA, RTD, Volts), burnout is not configurable but fixed
and display will show FIX LOW , FIX HIGH or FIX NONE.
The value will be out of range (low, high or undefined). The "BURNOUT" event
is only activated with the
B OUT LOW
or
B OUT HIGH
configuration.
- For RTD/OHMS sensors, a third wire burnout cannot be detected: the output
value will be undefined.
!
CAUTION
For configurable burnout, be aware that a current pulse of 0.125 mA will
occur regularly as part of the burnout detection and may disturb other
devices connected to the same sensor. For an application with another
controller connected on the same current loop, please remove the
burnout detection on your recorder.
Failure to comply with these instructions may result in product damage
