Switchingconsumer load with this voltage is prohibited!5.21.3 Triggering of the brakesThe signal for controlling the brakes is provided via a zero potential digital output (see "Digitaloutputs"). This normally open contact can be used either by the control for further processing ordirectly for switching the brake contactor (see fig.).InformationTo achieve optimum travel and position behavior, the brakes must be instantaneously opened andclosed via this contact!To reduce noises during brake disconnect, during normal operation the brakes should be switched tothe alternating current side (K4). The brakes are switched-off slower and thus quieter through therectifier.To ensure instantaneous brake application in emergencies, during inspection drives and return rides,use a second contactor (K3), which disconnects the brakes from the direct current side. Integrate thiscontactor into the safety circuit.Original operating instructionsZETADYN 3C Electrical installationR-TBA08_03-GB 1619 Part.-No. 00163322-GB44/204
