The timing relay works like a flashing relay. 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.
▶
Move the cursor to the right over the + character in order to input the
time setpoint value I1.
If you enter the same setpoint value at I1 and I2, the timing relay operates as
a synchronous flasher.
The + character means that the parameters of this timing relay can be
modified using the PARAMETERS menu.
▶
Confirm the value input with OK.
▶
Press ESC to leave entry.
Testing the circuit diagram:
▶
Switch easy800 to RUN operating mode and return to the program.
You can display every parameter set via the function relays menu.
▶
Move the cursor onto C 01 and press OK.
The parameter set for the counter is displayed with actual and setpoint
values.
▶
Move the cursor
Ú
downwards until you see the value QV.
▶
Switch input I05. The actual value changes.
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.
Doubling the flashing frequency:
▶
Select the power flow display T 01 and change the constant of the
setpoint time to 001,000.
When you press OK, the warning light will flash at twice the frequency.
If the setpoint value is a constant, it can also be modified via the
PARAMETERS menu.
