3.1 Basic Requirements
Non-sparking considerations
To maintain non-sparking characteristics, non-sparking linkages, actuators and hardware are required.
Distance from multinode
The maximum range of the WCX Series sensor system is 1000 ft [305 m], under ideal conditions, with a clear line of
sight. This will be reduced if the signal has to pass through dense materials such as brick, concrete, or wood. Metal
objects, tanks, pipes, or other structures, will not pass signals, however signals will tend to reflect off metallic
objects, such that clear line of sight may not be essential.
Angle to be measured
The angle input to the sensor input shaft must be no greater than approximately 270 degrees. If the input linkage
used applies an angular movement greater than this, proper calibration will not be possible. Angular motion beyond
270 degrees will engage the slip clutch within the product.
Sensor update rate
The maximum update rate possible is one measurement and update per second. Insure that the update rate chosen
will capture all necessary events when the monitored device is moving at its fastest speed. The rate of data updates
may be set through wireless builder. The update rate cannot be set locally using the IR port. If the factory default
update rate is not suitable for the application, it should be changed through wireless builder. Note that the default
refresh rate is factory set to one per 30 seconds to maximize battery life. Battery life will be affected by the update
rate selected; faster rates will decrease battery life.
Access to cover for configuring sensor, changing batteries
Configuring and calibrating will require access to the top of the sensor. Allow room for cover removal and for a
clear view of the IR sensing element (see WCX Series Sensor User's Manual).
Replacement of internal batteries will require removing the cover, and partial removal of a battery assembly. Allow
clearance for this (see WCX Series Sensor User's Manual).
Honeywell recommends that the sensor be removed from service and moved to a clean area before servicing. Use
care to avoid rotating the input shaft, causing the internal slip clutch to slip.
Proximity to high powered L-band transmitters
The WCX Series sensor system operates in the 2.4 Ghz. frequency band using an encrypted, spread-spectrum
data modulation, with very high immunity to interference from other signals. Other devices using low powered
signals in this frequency range are some cordless telephones, personal computer WI-FI links and routers, and
video/audio remote transmission links. These are highly unlikely to cause any signal overloading problems and
thus, de-sensitization of the data link (low signal).
However, some high-powered microwave heating devices may operate with 1,000 watts or more, and may operated
in nearby frequency bands. While likelihood of interference is very small, it is best to avoid locating sensors or
multinodes in very close proximity to such devices.
