Example 3: Automatic reset of error signal

The circuit diagram functions in the same way as Example 2.

In addition the marker M16 is reset every 60 seconds by

timing relay T8 (on-delayed, 60 s). Should I16 remain at 1,

M16 will continue to be set. Q1 is set briefly to 1 until I16

switches off again.

Expanding EZ700 You can expand EZ700 with EZ618-..-RE, EZ202-RE or

EZ620-D.-TE modules locally or use the EZ200-EZ coupling

module for remote expansion.

For this first install the units and connect the inputs and

outputs (

J chapter “Installation”, page 29).

You process the inputs of the expansion devices as contacts

in the EZ circuit diagram in the same way as you process the

inputs of the basic unit. The input contacts are assigned the

operand identifiers R1 to R12.

R15 and R16 are the group fault alarms of the transistor

expansion unit (

J section “Monitoring of short-circuit/

overload with EZ..-D.-T..”, page 238).

The outputs are processed as relay coils or contacts like the

outputs in the basic unit. The output relays are S1 to S8.

The following bus modules can also be connected:

• EZ205-ASI (AS-Interface),

• EZ204-DP (PROFIBUS-DP),

• EZ221-CO (CANopen) or

• EZ222-DN (DeviceNet).

I1-m16----ÄQ1

I16-------SM16

M16-------TT8

T8-------RM16

M16-------ÄQ4

EZ618-..-RE provides the outputs S1 to S6. The other

outputs S7, S8 can be used as markers.
