Notes: (1)
– applies to analog inputs ( mA, V, mV, Ω ),
(2)
– applies only to display of data in the connected programmer (AR950, AR956),
(3)
– for
Filt
=
1
, the response time is approx. 0.135 s; for
Filt
=
10
- approx. 1.5 s. Higher degree of filtration
means a more smooth measured value and a longer response time, which is recommended in the case
of turbulent measurements (e.g. water temperature in a boiler).
10. CONFIGURATION OF THE ALARM OUTPUT
The type of alarm characteristics for the OC output is determined by parameter 5:
oVt1
(see chapter 9, Table 9).
For
oVt1
=
retr
, the OC output is connected after the measured value exceeds the range defined by parameters 8:
bot1
and 9:
toP1
. In this mode, the alarm condition is additionally indicated by the blinking of the
A
LED diode on
the front panel.
When the
oVt1
parameter becomes equal to
inu
or
dir
parameter 6:
SEt1
and 7:
H1
apply, the status of the
output is indicated by the
A
LED (it is on when the output is switched on).
The principle of operation of the OC output in the individual operating modes is shown in the figures below.
11. SIGNALING OF MEASUREMENT ERRORS
The transducer detects the following measurement errors:
- exceeded processing time, downward or upward (se chapter 10, figure
a
);
- connected sensor or input signal other than the one set in the configuration parameters;
- defective sensor circuit.
Methods of signalization of measurement errors:
- blinking of the
A
LED (when parameter 5:
out1
=0:
retr
);
- measured value equal to -19999 or 19999 (see chapter 14, table 14.6, register address = 0).
