4 Installation
It is recommended that you read the relevant guides for installing, operating and
maintaining flammable gas and oxygen detectors (EN 60079-29-2) and toxic
detectors (EN 45544-4).
4.1 Regulations and operating conditions
•
Installation must comply with current edition of EN 60079-14 for systems installed in
explosive atmospheres and eventually with any local or national additional requirements
that may apply in the country of installation.
•
In general, the ambient temperature, the power supply voltage and power mentioned in
this document pertain to safety precautions against explosion. These temperatures are not
the detector's operating temperatures.
•
The equipment is authorized for use in zones 1, 2, 21 and 22 for ambient temperatures
ranging between -20°C to +60°C.
•
For the OLCT 80D id version, the sensor pack may be used in zones 0, 1, 2, 20, 21 and
22 if it is operated remotely with respect to the transmitter. The transmitter is not authorized
for use in zone 0 or 20.
•
The detection sensor must always be in contact with the ambient air. Therefore:
-
Do not cover the detection module.
-
Do not apply paint on the detection module.
-
Keep dust from building up.
4.2 Pre-installation Hardware Configuration
If one or two of the 4-20 mA inputs (
ANA1/ANA2 sensor inputs) is going to be used, see 0 on
