General parameters (continued)

Sensitivity Off

1 (min) 

to 9 (max)

Sensitivity level for detecting movement when the detector is off.

On delay

0 minute

-

0 to 99  

minutes

The On delay allows the first channel to switch on after the second channel. A typical 

application for this would be when a detector is controlling lighting and air condi-

tioning in an area. When the occupant is detected, the lighting will be turned on 

immediately, whereas the air conditioning may be turned on after 15 minutes. If the 

area is vacated before the detector times out, then the air conditioning will not have 

come on. The delay can be set for channel 1 only using this parameter.

Detection mode

Presence

-

Presence 

or absence

Presence mode allows the output to turn on when movement is detected and off 

when movement ceases. Absence mode allows the output to turn off when move-

ment ceases, but must be manually enabled first.

Lux On Level

999

145

1-950, 

999: 

OFF  

dimming 

regulation

Sets a minimum light level below which the PIR sensor is enabled,

allowing the lights to be turned on by movement.

Note: The "Lux Off level" value must always be greater than the "Lux On level” value.

Lux Off Level

999

225

1-950, 

999: 

disabled

Sets a maximum light level above which the PIR sensor is disabled, preventing the 

lights from being turned on by movement.

Lux On time

0

-

0 to 99  

minutes

When the ambient light drops below the Lux On Level, this is the delay before 

the lights comes on. If at any time during the timed delay the Lux level position is 

reversed, the process is cancelled. A minimum time of 15 seconds is defined for a 

value of 0. If you try to turn on the lights using a manual control, the lights will come 

on regardless of the ambient light level. However, if there is sufficient ambient light, 

they will turn off again after the Lux Off time.

Lux Off time

0

1

0 to 99  

minutes

When the ambient light exceeds the Lux Off Level, this is the delay before the lights 

go out. If at any time during the timed delay the LUX level position is reversed, the 

process is cancelled. A minimum time of approximately 15 seconds is defined for a 

value of 0.

Dimming parameters

Sets a target light level to be maintained by the lighting system

Max value

Maximum dimming output level.

Min value

82%

0 to 99%

Minimum dimming output level.

On value

99%

-

0 to 99%

Dimming output level when switched on (0-99).

Off value

0%

-

0 to 99%

Dimming output level when switched off (0-99). If a non-zero off value is set, the 

output will toggle between this value and completely off depending on the switch 

level On and Off values. For example, if it is light outside, the fittings will be off if 

there is no occupancy. If it is dark outside, they will adopt the preset off value. This 

feature is only enabled if “Min value” is set to 99.
