Configuration
The buttons are used to configure the two alarm relays. The configurable parameters are:
- The threshold,
- the hysteresis.
- The type of alarm detection, high or low.
Access to the configuration is done by pressing the
button.
1) Relays configuration
When entering configuration mode, the unit displays ‘
AL1
’. The button
provides access to configuration sections of
the relay 1. The button
provide access to configuration sections of the relay 2 , The unit displays ‘
AL2
’, The button
provides access to configuration sections of the relay 2 and the key
exits of configuration sections.
1.1) Threshold configuration
The device displays the message
‘
thr
’
. Pressing
button provides access to the threshold setting and pressing
button to switches to the next topic. The device displays the threshold value and the buttons
or
permits to incre-
ment or decrement the value. the display blinks during the setting. The adjusted value is automatically validated after 4
seconds if no button is pressed.
1.2) Hysteresis (dead band) configuration
The device displays the message
‘
db
’
. Pressing
button provides access to the hysteresis setting and pressing
button to switches to the next topic. The device displays the hysteresis value and the buttons
or
permits to incre-
ment or decrement the value. the display blinks during the setting. The adjusted value is automatically validated after 4
seconds if no button is pressed.
1.3) Type of detection
The user can, with this setting, set the direction of the threshold detection.
It works in this manner:
-
High threshold
detection (cooling):
.alarm is activated when temperature goes above threshold,
.alarm is removed when temperature goes below threshold minus hysteresis.
-
low threshold
detection (heating):
.alarm is activated when temperature goes below threshold,
.alarm is removed when temperature goes above threshold plus hysteresis.
The configuration possibilities are:
- High detection with the display
‘
AHi
’
.
- Low detection with the display
‘
ALo
’
.
The actual configuration is displayed on topic access.
Pressing
button validates the displayed choice and ends the configuration.
Press
button to display next choice.
2) End of configuration
The new parameters are saved in non volatile memory and the message
‘
End
’
is displayed briefly, indicating that the
parameters have been successfully saved. Then, device returns to measure mode.
Note:
If the waiting time for action on the buttons
&
exceeds 30 seconds then the device automatically returns to meas-
urement mode without saving the new settings.
