6.2. Indicators
(1) power (green): mode an communication indicator
(2) st. (red): mode and error indicator
The two indicator gives information in conjunction as
follows:
•
Measurement mode:
power: light, st.: dark.
•
Error state:
power: light, st.: blinking.
The number of blinkings gives the error information while
the output current is forced into 3.2 mA or 20.8 mA
(depends on setting).
1 blink : fatal error. (repairing: in factory service only).
2 blinks : input break (repairing: check the sensor and
wiring).
3 blinks : potentiometer mode is selected but the
potentiometer is not calibrated (see Chapter 7.)
4 blinks : measuring value out of range.
5 blinks : analog output scaling error (the instrument is
unable to convert the measured value into the 3.9-20.1 mA
range, while the output current is forced to 3.2 mA or
20.8 mA, depends on setting). (see Chapter 7.)
•
Configuration mode:
After connecting the infrared interface to the PC USB port
and pushing the “conf start” button and placing opposite the
interface optics and the instruments optics, starting the
configuration program and opening the proper virtual serial
port, the instrument is ready to communicate with the
program (for selecting the proper virtual port begin with the
last and than try the others).
st.: light, power: short flash in a case when a successful
communication has granted.
