PROGRAMMING
To change any of the MX20 settings, change the configuration
of the programming switches (see Figure 9) as required,
switch 4 controls LED state, switch 3 controls Pulse Count and
switches 1 and 2 control range.
Example: To change the range to 10 metres:
1. Set switch 1 to OFF (down position)
2. Set switch 2 to ON (up position)

PROGRAMMING OPTIONS DEFINITIONS
Pulse Count
This is the number of times the unit has to detect on both of its
sensors before signalling an output
LED
LED Off - LED disabled
LED On - LED signals a detection
WALK TEST
Note: It is recommended that the detection LED be enabled
during walk test to aid in set up. The detection LED lights each
time the MX20 detects your presence.
Note: When you conduct a walk test, make sure that the front
cover is in place. Do not conduct walk tests with the cover
removed.
The range of the detector increases without the protective front
cover. Therefore the front cover must be fitted to establish the
correct beam pattern. Use programming chart to adjust the
range as necessary. Pan and tilt the lens module over the field
of view to obtain the correct coverage area.
Detection Area Programmable between 5 & 20
metres
Coverage 90° detection angle, 20m x 20m
