Modality of tripping and restore
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.
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.
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 signal-
ling 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.
