Note (Wiring diagram)
For 2-channel control with cross-wire monitoring, connect the NC contact to S11/S12 and S31/S32 and bridge S21/S22 | F2 = Fuse for signalling outputs | For 1-channel control, connect NC contact to S11/S12 and bridge S21/S22 + S31/S32 | 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." | The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix. | Input 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. | "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" swit | F1 = Hybrid fuse | The control system recognises wire-breakage and earth faults in the monitoring circuit. | Connect potential p-type outputs of safety light grids/curtains to S12/S22. The devices must have the same reference potential. | Time delay: The time-delayed safety enable 37/38 is adjustable for 1 to 30 seconds drop-out delay (see setting intructions). | The wiring diagram is shown with guard doors closed and in de-energised condition.
