APS Enterprise Scale
2
SITE PREPARATION REQUIREMENTS
The Detecto APS Enterprise Scale is a precision weight-measuring instrument. As with any
precision instrument, they require an acceptable environment to operate at peak performance
and reliability. This section is provided to assist you in obtaining such an environment.
Site Requirements
In order to keep cooling requirements to a minimum, the indicator should be placed out of
direct sunlight and to provide adequate air circulation, keep the area around the indicator clear.
Make certain the indicator is not directly in front of a heating or cooling vent. Such a location
will subject the indicator to sudden temperature changes, which may result in unstable weight
readings.
Insure that the indicator has good, clean AC power and is properly grounded. In areas subject
to lightning strikes, additional protection to minimize lightning damage, such as surge
suppressors, should be installed.
Environmental Conditions
The APS Enterprise scale has been designed to operate under the following environmental
conditions:
Indoor
use
only.
Ambient temperature range of 14 to 104 °F (-10 to +40 °C
Main supply voltage fluctuations not to exceed ±10% of the nominal voltage.
Transient overvoltage’s according to Installation Categories II (Overvoltage Categories per
IEC 1010). Temporary voltage spikes on the AC input line that may be as high as 1500V
for 115V models and 2500V for 230V models are allowed.
Used in an environment of Pollution degrees 2 (i.e., where normally only non-conductive
atmospheres are present). Occasionally, however, a temporary conductivity caused by
condensation must be expected, in accordance with IEC 664.
