Description
z
Determine how to set the analog output when received wave error, etc. due to device error, accidental drain of
piping or ingress of bubbles.
z Settable ranges
(1) Analog output (4-20 mA) at error
HOLD (factory set): Outputs a current intensity preceding the error.
OVER SCALE: Outputs 23.2 mA.
UNDER SCALE: Outputs 0.8 mA.
ZERO: Outputs 4 mA.
(2) BURNOUT TIMER (time from error detection to BURNOUT processing) 0 to 100 seconds (factory set at 10
sec).
For actual keying, refer to the typical operation indicated below. Set the parameter protection to OFF beforehand
(Section 4.4.1).
Typical operation Set the BURNOUT to "OVER SCALE".
Set the BURNOUT TIMER to "20 sec".
* Set the piping parameters and "FLOW UNIT" beforehand.
