Wiring example

Note (Wiring diagram)"Start function / Reset button: The function "trailing edge" is programmed by means of the "AF" switch located underneath the housing cover (switch position = 1). The automatic start is programmed by bridging terminals X3/X5 and by switching the "AF" switConnect potential p-type outputs of safety light grids/curtains to S12/S22. The devices must have the same reference potential.Early switch-off of time delay: The drop-out delay time can be ended early via the input RT. The input RT makes it possible to "switch off" the time-delayed enabling circuit 37/38 before the set time has elapsed."F1 = Hybrid fuseF2 = Fuse for signalling outputsFor 1-channel control, connect NC contact to S11/S12 and bridge S21/S22 + S31/S32For 2-channel control with cross-wire monitoring, connect the NC contact to S11/S12 and S31/S32 and bridge S21/S22Input level: The example shows a 2-channel control of a guard door monitoring with two position switches, whereof one with positive break, external reset button (R) and feedback circuit (H2). (example without cross-wire monitoring)Relay outputs: Suitable for 2 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts.Setting of the drop-out delay time is carried out by means of a potentiometer from the front of the enclosure.The control system recognises wire-breakage and earth faults in the monitoring circuit.The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix.The wiring diagram is shown with guard doors closed and in de-energised condition.Time delay: The time-delayed safety enable 37/38 is adjustable for 1 to 30 seconds drop-out delay (see setting intructions).
