4-20 Drawing a Circuit Diagram with Pico
At least two elements are needed in the circuit diagram for
a timing relay:
• A relay contact in the contact field, in this case T2.
• A trigger coil in the coil field, in this case TT2.
You can also wire up the reset coil RT2 if you wish to use
an external reset signal. Enter the number of the relay
contact T2 and press Ok.
The parameter set for timing relay T2 is displayed. Specify
the function of the relay.
Parameters for Timers
The parameter display for a timing relay is used to modify
the switching function, setpoint time and timebase units
and to enable or disable parameter access.
A symbol “{” in front of TRG or RES indicates whether the relay function is wired
in the circuit diagram. The coil terminals are not shown if you access the
parameters via the PARAMETER menu option. The actual time is only displayed
in Run mode. To view the actual time, call up the parameter display via the power
flow display or using the PARAMETER option.
