3.3 ENVIRONMENTAL CONDITIONS
Important: 2AP cover
Do not operate the 2AP with the cover removed. Doing so can defeat the over-travel sensors which
may result in physical damage to the 2AP and/or any attached equipment. Such damage is not
covered under warranty.
The 2AP cover protects the internal drives and electronics of the 2AP. When the cover of the 2AP is
fitted back onto the unit be sure to reconnect the detachable ground wire to the chassis to maintain
electrical safety and RFI screening. All four latch handles and security screws must be secured.
Important: Worm / Spur Gear Drive Contamination
Proper worm/spur gear mesh is a critical factor in the operation of the 2AP GD. To ensure that the
mesh is in no way affected, it is recommended that the 2AP NOT be operated for extended periods
of time with the main cover removed. This is especially important in any dusty, windy or high
moisture environments. Any debris adhering to the worm and/or spur gear can adversely affect the
operational accuracy of the 2AP and cause premature wear.
Important: Operating Temperature
A standard 2AP has an operating temperature range of 0
°C to +50°C. For remote locations with
harsh temperature conditions, the Cold Weather Cover combined with two (optional) internal
heaters can increase the operating range to -50
°C to +50°C, see table 4.
Table 4: 2AP Operating Temperature Range.
Standard 2AP
0 °C to +50°C
2AP with Cold Weather Cover -20 °C to +50°C
2AP with Cold Weather Cover and Heater Kit -50 °C to +50°C
2AP with Cold Weather Cover and Extreme Heater Kit
-50 °C to +50°C (prolonged
exposure and wind-chill)
To ensure that the 2AP operates without failure due to extreme temperature conditions, it is
recommended that the Cold Weather Cover installation / removal be determined as per the
following:
Below 0°C
: Cold Weather Cover must be installed.
0°C to +20°C : 2AP may be operated with Cold Weather Cover installed or removed.
Above +20°C (for more than 8 hours continuously): Cold Weather Cover must be removed to
prevent overheating.
Important: Precipitation
With the 2AP cover installed properly such that all four of the latch handles and security screws are
secured the 2AP is environmentally protected to IP65, according EN 60529: 1991 + CI 1993. This
qualifies the 2AP to be used in weather conditions with all types of precipitation.
