Monitoring of short-

circuit/overload with

EASY..-D.-T..

Depending on the type of easy in use, it is possible to use the

internal inputs I15 and I16, R15, R16 to monitor for short-

circuits or overloads on an output.

• EASY82 .-D.-T..:

– I16: Group fault signal for outputs Q1 to Q4.

– I15: Group fault signal for outputs Q5 to Q8.

• EASY620-D.-TE:

– R16: Group fault signal for outputs S1 to S4.

– R16: Group fault signal for outputs S5 to S8.

The following examples are for I16 = Q1 to Q4.I15 indicates

in the same way short-circuits and overloads on Q5 to Q8.

Example 1: Output with fault indication

Figure 131: Circuit diagram for fault output via I16

The above circuit diagram functions as follows:

If a transistor output reports a fault, M16 is set by I16. The

break contact of M16 switches off output Q1. M16 can be

cleared by resetting the easy power supply.

State

Outputs I15 or I16, R15 or R16

No fault found 0 = switched off (make contact)

At least one output has a

fault

1 = switched on (make contact)

I15 and I16 can only be edited with easy versions which

have transistor outputs.
