The timing relay works like a flashing relay. The EZD symbol
for the flashing relay is
Ü
. The function is set on the top right
beside the number in the parameter display.
The time base is set to the right of the “flashing” function.
Leave the time base set to
S
for seconds.
X
Move the cursor to the right over the
+
character in order to
input the time setpoint value
>I1
.
If the same setpoint value is input for
>I1
and
>I2
, the
timing relay functions as a synchronous flasher.
The
+
character means that the parameters of this timing relay
can be modified using the PARAMETERS menu.
X
Confirm the value input with
OK
.
X
Press
ESC
to leave circuit diagram entry.
X
Complete the circuit diagram.
X
Test the circuit diagram using the power flow display.
X
Switch EZD to RUN mode and return to the circuit diagram.
Each parameter set can be displayed using the power flow
display for the circuit diagram.
X
Move the cursor onto
C
01
and press
OK
.
The parameter set for the counter is displayed with actual and
setpoint values.
X
Move the cursor
Ú
downwards until you see the value QV>.
X
Switch the input I5. The actual value changes.
On the display
C_
indicates that the counting coil is actuated.
If the actual and upper setpoint values of the counter are the
same, the timing relay switches the warning light on and off
every 2 seconds.
