Timer function (extra code)
Using the timer function, the control action can be influenced by means of the adjustable time
power ON, by pressing the key or via the logic input, the timer start value
value has gone above or below a programmable tolerance limit. When the timer has run down, several events are triggered, such as
control switch-off (output 0%) and setpoint switching. Furthermore, it is possible to implement timer signalling during or after the timer
count, via an output.
The timer function can be used in conjunction with the ramp function and setpoint switching.
Table: Timer functions (using the example of a reversed single-setpoint controller)
Tolerance limit
The position of the tolerance limit depends on the controller type:
- Single-setpoint controller (reversed, heating): Tolerance limit is below the setpoint
- Single-setpoint controller (direct, cooling): Tolerance limit is above the setpoint
- Double-setpoint controller: Tolerance limit is below the setpoint
If, during the control process, the process value goes above/below the tolerance limit, then the timer will be stopped for the duration of
the infringement.
Display and operation
The timer value is displayed at the operating level and remains so permanently (no time-out).
Operation is from the keypad, when the timer value is visible in the display, or via the logic input. The operating options comprise start,
stop, continue and cancel timer function, and are shown differently in the display.
The current timer value and the timer start value are accessible and adjustable at any time at a separate timer level.

Function
Time-limited control
The control action is switched off after
the timer has run down (output 0%)
Time-dependent setpoint switching
After the timer has been started, the
process is controlled to setpoint
After the timer has run down, the
controller automatically switches over
to
Time-delayed control
The control action starts after the timer
has run down.
Timer with signalling
After the timer has been started,
counted down to 0. The control action is
independent of the timer.
With this timer function, too, the end of
the timer count-down can also be
signalled via an output.
