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 sensor system is 1000 feet (305 Meters), 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.
