7. Modality of tripping and restore
7.1 Alarm
On the relative channel, if the threshold value set is exceeded of
+1°C, after 5 seconds the ALARM relay is energized and the ALARM
led is.
The alarm rearm (relay de-energized and the involved LED off)
occurs when the temperature goes down of 2°C respect at the
threshold value set.
7. 2 Trip
On the relative channel, if the threshold value set is exceeded of
+1°, after 5 seconds the TRIP relay is energized and the TRIP led is.
The trip rearm (relay de-energized and the involved LED off)
occurs when the temperature goes down of 2°C respect at the
threshold value set.
7.3 To silence alarm
If the Hold function is disabled, it’s possible to silence the alarm
condition. During the alarm condition the ALARM relay and the
“ALARM” optical signalling are enabled.
Pressing the Reset button, the relay will be de-energized while the
optical signalling of the alarm condition becomes flash.
If the temperature increases up to reach the (TRIP temperature - 1°C),
the relay and the optical signalling are enabled another time.
If after the reset, the temperature goes down under the threshold
value set, the flashing optical signalling will be automatically
deleted.
