Switch 1 on the SwitchBox will give the possibility to change<br />

the daylight-override between 150% (for sensor Mode 1 –<br />

Switch 1 is set to off) or 250% (for sensor Mode 2 – Switch<br />

1 is set to on). At this time Switch 2 has no function. As<br />

soon as the light level goes below 100%, the SwitchBox will<br />

switch on the ballast again.<br />

If there is no ballast connected to the 1-<strong>10V</strong> DC output<br />

as would be the case when a fixed output ballast/driver is<br />

used, the SwitchBox will detect this and will automatically<br />

set the daylight-override to 250%. As soon as the light<br />

level goes below 100%, the SwitchBox will switch on the<br />

ballast again.<br />

2.8 Startup behavior at power up<br />

2.8.1 ActiLume 1-<strong>10V</strong> Sensor and a 0-<strong>10V</strong> ballast<br />

or driver<br />

If an ActiLume 1-<strong>10V</strong> sensor is used in combination with<br />

a 0-<strong>10V</strong> ballast or driver, at power up of the system the<br />

ballast will be controlled by means of the daylight control<br />

mechanism inside the ActiLume 1-<strong>10V</strong> sensor. The first<br />

15 to 30 seconds after power up the PIR will not function<br />

because it needs this time to start up. If during the time set<br />

by the timer of the sensor, there is nobody present, then<br />

after this delay time the sensor will start to dim down in<br />

about 15 seconds to the minimum level of 2.5V on the diminput<br />

of the ballast.<br />

During this delay there will<br />

be daylight regulation<br />

A scenario where daylight regulation is active when the control space is occupied and when no occupancy is detected for the delay<br />

time then the lights dim to the minimum level of 2.5V on the dim-input of the ballast.<br />
