ALARMS
9.1
Alarms
CODE MEANING
AL
Minimum alarm temperatures (HACCP alarms)
Solutions:
• check the cell temperature (EVXV201 only)
• check the temperature associated with the alarm (but
EVXV201)
• refer to:
- parameters A1 and A2 (EVXV201 only)
- see parameters A0, A1 and A2 (but EVXV201)
Main consequences:
• the instrument will store the alarm (EVXV201 only)
• if parameter A0 is set to 0, the instrument will store the
alarm (but EVXV201)
• the alarm output will be activated (provided that param-
eter u1 and/or parameter u11 is set to 3)
CODE ALARM TYPE (CRITICAL VALUE)
AL
minimum temperature alarm (the minimum temperature
of the cell during the alarm)
AH
maximum temperature alarm (the maximum temperature
of the cell during the alarm)
id
door microswitch input alarm (the maximum tempera-
ture of the cell during the alarm); see also parameter i4
PF
power supply interruption alarm (cell temperature when
power is restored); see also parameters A10 and A12
Notes:
• the instrument stores the minimum and maximum tem-
perature alarm provided the temperature associated with
the alarm is that of the cell (parameter A0 = 0)
• to avoid repeatedly storing alarms due to interruptions
in the power supply, disconnect the power when the
instrument is switched off
• if the duration of the power supply interruption alarm is
long enough to cause a clock error (code “rtc”), the instru-
ment will not provide any information about the alarm
duration
• if the instrument is switched off no alarms will be stored
When the problem that caused the alarm disappears, the display is
restored to normal operation, with the exception of the power supply
interruption alarm (code “PF”) which requires manual restoration of
the normal display.
To manually restore the normal display:
• press a key.
If parameter u1 and/or parameter u11 is set to 3, pressing the key will
disactivate the alarm output.
The HACCP LED provides information regarding the storage status of
the alarms; see paragraph 8.1.
6.2
Display of HACCP alarm information
For EVXV201, EVXV203, EVXV204, EVXV205 and EVXV215:

label available
• press and release the UP or DOWN key to select “LS”
• press and release the SET key: the display will show one of the codes
included in the table in paragraph 6.1.
To select an alarm:
• press and release the UP or DOWN key (to select, for example, “AH”).
To view the information about the alarm:
• press and release the SET key: the HACCP LED will stop flashing and
remain permanently on and the display will show the following
sequence of information (for example):
INFO.
MEANING
