The figures show the Timer functions (Typ=0) with countdown (Fun=0). For counters
(Typ=1) in cases out=1...6, "Timer" and "Timer 1" become "Counter 1" and "Counter
2". For the frequency meter (Typ=2) with out=4, there is a second setpoint for
hysteresis.
a) IN3 = 0: IN 3 with HOLD display function;
b) IN3 = 1: IN3 with UP/DOWN function
out=1 Standard U1 Function
Timing begins and proceeds until the trip point if the IN1 signal is present. The output
energizes when the set time has elapsed.
When the IN2 signal arrives, the output resets and the timer returns to its preset value.
The timer restarts when the IN1 signal is received.
In case A, IN3 does not cause changes in operation of inputs and outputs, but simply
freezes the displayed value.
In case B, if IN3 arrives when the timer count has already started but not yet finished,
it causes the count to reverse direction (up instead of down).
In this condition, the current timer value continues to increase until reaching the full
scale of the time base.
When IN3 is removed, the countdown resumes from the value reached and goes
toward the trip point.
out=2 Cyclical monostable U2 Function
If input IN1 is present, when the timer reaches the trip point it immediately reloads the
preset value and begins a new countdown (cyclical function).
The output energizes each time the setpoint is reached and stays energized for time
S.P.2.
The arrival of input IN2 resets the output and the two timers (S.P.1 and S P.2) return
to their preset values.
In case B, input IN3 reverses the count of timer 1 (S.P.1) only; therefore, timer 2 (if
started) always reaches end of time state regardless of the presence of IN3.
