Operation Manual: 111508-2100-OM01V7.X Autrol® Series
2.2 Models and Specifications Check
The model name and specifications are indicated on the top nameplate fixed to the
transmitter. Please check your specification and model supplied for your installation. Please
ensure that LRL(Lower Range Limit)/URL(Upper Range Limit), min/max span specifications
and sensor type are in line with your application requirements.
2.3Storage
The following precautions must be observed when storing the instrument, especially for long
periods.
(1)Select a storage area that meets the following conditions:
a) It is not directly exposed to rain, water, snow or sun light.
b) It is exposed to minimum vibration and shock.
c) If possible, it is advisable to store at normal temperature and humidity (approx. 70°F,
65% RH). However, it can also be stored under ambient temperature and relative
humidity within the following published ranges:
● Ambient Temperature: -40 ~ 85°C (without LCD) * or -20 ~ 60°C (with LCD
module) *
* General use only. For explosion proof versions follow product certification
reqmts.
● Relative Humidity: 5% ~ 98% RH (at 40°C)
(2)When storing the transmitter, repack with original (or similar) packaging that was shipped
from the factory.
2.4 Selecting a Suitable Location for Installation
The transmitter is designed to withstand severe environmental conditions. However, to
ensure stable and accurate operation for extended years, the following precautions must be
observed when selecting an installation location.
(1) Ambient Temperature:
Avoid locations subject to wide temperature variations or a significant
temperature gradient. If the location is exposed to radiant heat from plant
equipment, provide adequate insulation or ventilation.
(2) Ambient Atmosphere
Avoid installing the transmitter in a corrosive atmosphere. If the transmitter
must be installed in a corrosive atmosphere, there must be adequate
ventilation as well as preventive measures to minimize intrusion or stagnation
of rainwater or condensation build up through its electrical conduits. Moreover,
there should be appropriate precautions taken to prevent corrosion build up
due to condensation or moisture collected within conduits and terminal boxes
over extended periods of operation. Inspect periodically as required.
(3) Shock and Vibration:
Select an installation site subject to minimum shock and vibration.Although
the transmitter is designed to be relatively resistant to shock and vibration
we highly recommend following good engineering practices.
(4) Installation of Explosion Proof rated Transmitters
Explosion proof rated transmitters must be installed in hazardous areas
according to the area classification for which they are certified.
(5) Accessibility
Always select a location that provides easy access to transmitter for
maintenance & configuration checks.
