• On probe 2, there is only a high alert at 23.5°C with a come back to normal at 20°C.

The product enables the detection of a threshold overpassed (high and low) for each
probe and to repeat this alert depending on a determined period (register S321 x S322).
Settings associated to this operating mode are:
• Sampling period (register 321),
• Alarm repetition (register 322),
No
• Activation of the probes (register 324).
• Alarm configuration on probe 1 (register 330) and probe 2 (register 340).
• High threshold on the probe 1 (register 331) and probe 2 (register 341).
• Hysteresis for high threshold on probe 1 (register 332) and probe 2 (register 342).
Yes
• Low threshold on the probe 1 (register 333) and probe 2 (register 343).
• Hysteresis for low threshold on probe 1 (register 334) and probe 2 (register 344).
Example:
Registers

In this example:
• The product measure temperature only on probe 1
• On probe 1, there is a high threshold at 70°C with a come back to normal at 65°C
and a low threshold at10°C with a come back to normal at 12°C
• A sampling (reading) every 10 minutes (300 x 2 seconds = 10 minutes)
• As long as the alarm is active (threshold always overpassed), this alarm will be
repeated every 2 samples (so every 20 minutes).
No
Yes
*The "alarm status" byte gives the information if the alert is activated or not and so allows
to dissociate a 0x58 frame sent to alert that the threshold is overpassed from a 0x58 frame
sent to inform about come back to normal.
Encoding Value Result
Decimal 0 Alarm mode
Decimal 1 Only probe 1 is activated
Decimal 3 High and low threshold activated on probe 1
Decimal 700 High threshold is 70°C
Decimal 50 Hysteresis for high threshold is 5°C, the
come back to normal is at 65°C
Decimal 100 Low threshold is 10°C
Decimal 20 Hysteresis for low threshold is 2°C, the come
back to normal is at 12°C
A sampling is done every 10 minutes (300 x
Decimal 300
2 seconds = 10 minutes)
Alarm will be sent every 2 sampling if
Decimal 2
always activated
