Testing and use

6.1 Power on

When the detector is powered on, the red LED on the base board starts blinking at slow in-
termittence. Output current is approximately 1.5 mA.
After one minute, the red LED flash rate is equivalent to the detector working status (see
table in paragraph 6.3) and the output current is 4.0 mA.
Once the warm-up phase is over, the detector can function correctly, although the optimal
performances will be achieved after two hours.
If the detector is provided with display, please refer to the additional technical handbook of
display board.

6.2 Testing

The detector is factory calibrated for the specific gas required by the customers. Future
adjustment of the pre-set calibration can be carried out by employing the calibration keypad
or display where it is provided.
It's strictly forbidden open and close the equipment when it's installed in hazardous area
and it's powered-on. This operation can be conducted in safe zone and without power sour-
ce. After 10 minutes from power source interruption, the equipment can be opened.
It's strictly recommended the use of personal protective equipment (PPE) during operations
inside the enclosure.
