Light returns to the previous dimming level when switched off and on again, even at power failure.
c) Synchronization of switching state and dimming direction:
For physical reasons, a PUSH-DIM system can work asynchronously; in other words, the switching state
and dimming direction of the individual luminaires are different. The following steps are used to
synchronize a PUSH-DIM system:
1. Step: Press and hold (> 0,5 s) All luminaires switch on
2. Step: Press briey (< 0,5 s) All luminaires switch o
3. Step: Press and hold (> 0,5 s) All luminaires switch on and dim
d) The PUSH-DIM wiring and the operator button must be rated for mains voltage (240 V).
e) It must be AC voltage with a frequency between 48 and 63 Hz.
f) Warning: Make sure the conduct core connected to PUSH terminal is not exposed, as it connected to the
live wire.
Asynchronism
As a matter of principle, asynchronisms can occur with push-button operation in systems with more than one
ECGs. The higher the number of ECGs and the longer the control line length, the greater the chance of
asynchronisms. In order to avoid lighting installations running asynchronously in practice, the permissible
number of ECGs(20) and the total line length of 25 meters must be adhered to.
DALI Dimming
Circuit diagram
Instructions
a) Compatible with both DALI-2 application controller or DALI-I master.
b) Connect the DALI signal to the DA1 and DA2 terminals (polarity-free)
c) Addressing possible:
•Individually (max. 64 IP addresses)
•In groups (max. 16)
•All together
d) The least dimming depth of DALI is of 1% * Iout.
e) Built--in with permanent memory: light returns to the previous dimming level when switched off and on
