L-SERIES can signal some faults that may occur to
the temperature probes. When a fault is detected,
an error message is displayed instead of the
temperature value of the faulted probe.
When this occurs the controller cannot work
properly, after about a minute, all the output relays
will turn o (safety condition) and a signaling buzzer
starts.
Error Messages:
Low
The temperature probe is disconnected or the
temperature is below 1°C. The most likely cause
is a breakdown of the cable; check carefully the
connection cable and, if required, replace it with a
new one having same characteristics.
High
The temperature probe is shorted or the
temperature is higher than 119°C. The most likely
cause is an accidental contact along the cable;
check carefully the connection cable and, if
required, replace it with a new one having same
characteristics.
Err
Signaled when the wet bulb temperature is 5°C
higher than the dry bulb temperature. This means
that the wet and dry bulbs were exchanged or that
there is a fault in the wiring or in the probes. Check
carefully the connection cables.
