•
Secure the detector cover with the four screws.
• Power the device on and set the parameters using the “ SAMON GLACIÄR ” app (see the relevant chapter) if the settings were
not previously made using the rotary switch.
3.4 Additional installation notes
Before commencing electrical installation and wiring, carefully read the following notes:
• Power must be supplied by a safety isolation transformer (Class 2) with no earth connection on the secondary winding.
•
The cable for the relays must be sized and fitted with fuses based on the rated voltages, currents, and environmental
conditions.
• If stranded wires are used, it is recommended to use an end terminal.
•
To comply with RFI immunity regulations, the communication cable shield on the supervisor must be earthed (e.g., to the
chassis, earth bar, etc.)
• Complete all wiring before powering on.

OPERATION
4.1 Power on
When power is connected, the device begins the start-up cycle, divided into two phases:
• start-up
•
warm-up
The start-up sequence lasts around 20 seconds, during which the main functions of the gas detector are initialized and
verified. In this phase, the LEDs on the front panel are activated in sequence, and the device cannot yet be used.
At the end of the start-up sequence, the warm-up phase commences, during which the sensor output signal is adjusted
and stabilized. In this phase, the device can be used to detect gas and installation can be completed via the rotary
switch, app or controller; nonetheless, the measurement is less reliable, and calibration is not possible.
During the warm-up phase, the green LED flashes around twice every second. The duration of the warm-up phase
depends on the sensor technology used:
• Semiconductor = 5 min
•
Electrochemical = 5 min
• Infrared = 2 min
The duration of the warm-up phase may also vary according to environmental conditions. In this phase it is important not
to cause sudden changes in gas concentration, so as to avoid compromising correct measurement by the sensor.
IMPORTANT: the sensors may take longer to warm up than specified; in these cases, do not take any action,
wait for the device to stabilise. The time needed for complete stabilisation of the device may vary from 2 hours
(minimum time) to 24 hours (recommended time).
