Note (Contact resistance):
in new state
Note (General):
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
Note (Short-circuit recognition):
Level 1
Note (Wiring diagram):
The wiring diagram is shown with guard doors closed and in de-energised condition.; 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.; The control recognises cross-short, cable break and earth leakages in the monitoring circuit.; Input level: the example shows a 2-channel control of an Emergency Stop command device (level 1) with external reset button (R), and guard door monitoring (level 2) with feedback circuit (H2).; Automatic start (level 1): The automatic start is programmed by connecting the feedback circuit to the terminals X1/+24 V DC. Automatic start (level 2): The automatic start is programmed by connecting the feedback circuit to the terminals X2/+24 V DC. If the feedback circuit is not required, establish a bridge.; 1 NC contact each time communicates the status of level 1 and level 2
