A green ligh-emiing diode emis a signal when he device is swiched on. Afer he changeover from overexciaion volage o holding volage, he diode coninues o illuminae a reduced brighness. Holding volage The holding volage can be adjused via he DIP swich. The swiches may only be swiched in de-energised sae and may only be adjused as depiced. The se holding volage value should equal 3 imes he drop-ou volage of he safey brake.

Therefore, when dimensioning he overexciaion ime O, please selec a leas double he separaion ime 2 on each brake size (caalogue values). The overexciaion ime O can be adjused via he DIP swich o 150 ms, 450 ms, 1 s, 1.5 s and 2 s ± 1 %. The DIP swiches may only be swiched in de-energised sae and may only be adjused as depiced. The volage reducion mechanism (DIP swich 7) mus be de-acived. Release monioring The inelligen release monioring can be deacivaed for cerain applicaions in order o preven errors. Possible applicaions: Parallel operaion of several brakes Damped brakes Unspecific brakes The release monioring recognises he movemen of he armaure disk for opening he brake afer swich-on as well as he movemen of he armaure disk for closing he brake afer swich-off.
