Evco S.p.A. • Code 104C30S40E02 • page 4/6
PT • 39/10
Consequences:
• all outputs will be deactivated
H-t For EVC30S40J7XXX02 / 03 / 04 / 05.
use temperature alarm
Solutions:
• press B2 to display the use temperature
• see parameters P14 and P15
Consequences:
• all outputs will be deactivated
When the cause of the alarm has disappeared, the instrument restores
normal functioning, except for the use temperature alarm
(code “H-t”), which requires the B1 key to be pressed or the encoder
button). This switches the instrument off.

INTERNAL DIAGNOSTICS
13.1 Internal diagnostics
CODE MEANING
AL1 For EVC30S40J7XXX00 / 01.
chamber probe error
Solutions:
• check that the probe is a J thermocouple
• check the integrity of the probe
• check the instrument-probe connection
• verify the chamber temperature
Main consequences:
• the temperature regulation output will be deactivated
AL1 For EVC30S40J7XXX02 / 03 / 04 / 05 (if parameter P3 is set
at 0).
top probe error
Solutions:
• the same as the previous case but relative to the top probe
Main consequences:
• the top output will be deactivated
For EVC30S40J7XXX02 / 03 / 04 / 05 (if the parameter P3
is set at 1).
chamber probe error
Solutions:
• the same as the previous case but relative to the chamber
probe
Main consequences:
• the top output and the floor output will be deactivated
AL2 For EVC30S40J7XXX02 / 03 / 04 / 05 (if parameter P3 is set
at 0).
floor probe error
Solutions:
• the same as the previous case but relative to the floor
probe
Main consequences:
• the floor output will be deactivated
When the causes of the alarm have disappeared, the instrument will
go back to normal functioning.
