Chosen model, will appear a short reminder referring to the
configuration of some particular parameters (delays) that define the
operation mode of the relay outputs.
The explanation is detailed below in section HYSTERESIS OFF.

Defines the type of ALARM of the sensor and establishes how they should be set the
thresholds of the various alarm levels. In the specific:
INCREASING: The alarm levels must be set from the smallest to the largest or, if needed,
the same. (ALARM 1 ≤ ALARM 2 ≤ ALARM 3 ≤ FULL SCALE of the SENSOR). All our sensors, except
for oxygen ones, are set with this type of alarm.
DECREASING: The alarm levels must be set from the largest to the smallest value or, if

needed, the same. (ALARM 1 ≥ ALARM 2 ≥ ALARM 3 ≥ FULL SCALE of the SENSOR). Some oxygen
sensors can be set with this type of alarm.
OXYGEN: Alarm levels should be set to detect concentrations lower (deficiency) or higher
(excess) than the normal presence of oxygen in the air (20.9% v/v). (ALARM 2 ≤ ALARM 1 ≤
20.5% vol and ALARM 3 ≥ 21.2% vol and not beyond the FULL SCALE of the SENSOR). Our oxygen
sensors are set with this type of alarm.
Only for Oxygen detectors, ALARM 2 is displayed as AL
ZONE: Sets the area that will be associated with the sensor. The number of available areas
ZONE
is max 6. The area 0 means that the sensor is not associated in any area
(Threshold Limit Values) are exposure limit values (OELs-Occupational Exposure Limits) for
toxic substances to which workers may be exposed every day for the entire duration of
working life without harmful effects. i.e. SENSOR SCALE ≥ ALARM 3 ≥ ALARM 1 ≥ ALARM
TLV
2 ≥ FAULT must be set in increasing order. Each alarm level is a value obtained with a
temporal average. TLVs in detail are:
ALARM 1 = TLV-TWA (Time-Weighted Average) is the time-weighted average concentration for a
conventional 8-hour workday and a 40-hour workweek, to which it is believed that nearly all workers
may be repeatedly exposed, day after day, without adverse effect. This alarm is triggered when the
weighted average concentration within 8 hours exceeds the set threshold.
ALARM 2 = TLV-STEL (Threshold Limit Value–Short-Term Exposure Limit) is the concentration to which it is
believed that workers can be exposed continuously for a short period of time without suffering from
irritation, chronic or irreversible tissue damage, or narcosis. STEL is defined as a 15-minute TWA
exposure, which should not be exceeded at any time during a workday. This alarm is triggered when
the weighted average concentration in the last 15 minutes, exceeds the set threshold.
ALARM 3 = TLV-C (Threshold Limit Value-Ceiling) is the concentration that should not be exceeded
during any part of the working exposure. This type of alarm is triggered when the instantaneous
concentration exceeds the set threshold. Are not carried out, time weighted average.
Only our sensors for detection of toxic gases can be set up with this type of alarm.
PARKING EN: The alarm levels should be set so increasing, i.e. SENSOR SCALE ≥ ALARM 3 ≥
ALARM 2 ≥ ALARM 1 ≥ FAULT. In this case, the first two levels of alarm representing a value
obtained with a time average between 5 and 60 min. (according to standard EN 50545-1 for the car
parks). This value can be set via the parameter TWA. ALARM 3, however is instantaneous.
This type of alarm
parks (series TS282 and TS293 /EC/EN/EN2) or the dual sensors (series TS255).
Indicates the value beyond which the relative Alarm level (Relay) will be activated.
