EVX012 Alarm module version 1.0
3 USER INTERFACE
3.1 Preliminary signals
The user interface consists of a custom 4-digit display (with decimal
points and function icons) and six keys (SET, UP, DOWN, MUTE, TEST
and ON/STAND-BY).
Operating Statuses:
• “on” status (the instrument is powered and on
• “stand-by” status (the instrument is powered but is switched off via
software)
• “off” status (the instrument is not powered).
Hereafter, with the word “start-up” means the passage from stand-by
status to on status; the word “shutdown” means the passage from on
status to stand-by status.
When th e power is switched back on, the instrument displays the
status that it was in at the time it was disconnected.
3.2 Switching on/off of the instrument
• make sure that the keyboard is not locked and that no other opera-
tion is in progress
• press and hold down the ON/STAND-BY key for 2 sec: the on/
stand-by LED will switch off/on.
3.3 The display
If the instrument is switched on, during normal operation, the display
will show the cell temperature.
If the instrument is switched off, the display will be switched off.
3.4 Activating/deactivating function “test”
• make sure that the keyboard is not locked and that no other opera-
tion is in progress
• press and release the TEST key : the LED will switch on/off.
Pressure of TEST key provokes the closure of the test relay in the alarm
module EVX012 and the lack of power supply in the backup module
EVC99P00X7XXX00; during the lack of power supply, the alarm mod-
ule is powered by the backup battery.

5 HACCP FUNCTION
5.1 Preliminary notes
The instrument is able to store up to 9 HACCP alarms, after which the
most recent alarm will substitute the oldest.
The instrument provides the following information:
• critical value
• the date and time the alarm was signaled
• the duration of the alarm (from 1 min to 99 hours and 59 min, partial
if the alarm is in progress).
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:
•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
2.2 Installation
Back panel installation using M3 studs.
2.3 Installation notes
• make sure that the working conditions (operating tempera-
ture, humidity, etc.) fall within the limits inidcated in the tech-
nical specifications
• do not install the device near heat sources (resistors, hot air
ducts, ect.), near devices with strong magneti (large diffu-
sors etc.) and places subject to direct sunlight, rain, humidity,
excessive dust, mechanical vibrations or shaking
• in accordance with laws on safety, protection against possi-
ble contact with electrical parts must be ensured via the cor-
rect installation of the instrument; all the parts that ensure
such protection must be secured in such a way that they
cannot be removed without the using a special tool.
Contact 19-21 of the backup module EVC99P00X7XXX00 will be closed
provoking the activation of the power supply presence digital input
in the alarm module EVX012; the display of the module will show “iA”
flashing and the alarm output will be activated.
3.5 Locking/unlocking the keyboard
To lock the keyboard:
• make sure that no other procedure is in progress
• press and hold down the TEST and ON/STAND-BY keys for 1 sec:

If the keyboard is locked, the following are not permitted:
• switch on/off of the instrument
• activating/deactivating function “test”
• changing the upper alarm set (with the procedure described in 4.2)
The operations cause the display of the label “Loc” per

(1) the unit of measurement depends on P2
(2) properly set the parameters corresponding to the regulators after modifying parameter P2
(3) the parameter has effect even after an interruption in the power supply that occurs while the instrument is switched on
(4) during activation of the door microswitch input, the maximum temperature alarm is absent, provided the alarm was signaled after the activation of the input
(5) the instrument stores the alarm once the time established in parameter i2 has expired; if parameter i2 is set to -1, the instrument will not store the alarm.

11 ELECTRIC CONNECTION
11.1 Preliminary notes
With reference to the electrical wiring diagrams:
• the serial port is the port for communicating with the monitoring system (via serial interface, via TTL, MODBUS communications protocol), with the programming key or with the data recording device EVUSBREC01;
the port must not be used for these three different purposes simultaneously.
11.2 Electrical wiring
