The following parameter is then available: #T.LbA LBA delay Setting a value between 1 and 9999 sec the alarm works as LBA+Sensor break with delay [1] This condition is shown by means a red led as well as the blinking PV display. Setting OFF the alarm works as Sensor break with immediate action.

6 - Special functions 6 SPECIAL FUNCTIONS Two special functions are available: 6.1 Start-up 6.2 Timer In order to have the above functions the product code digit E must be 2 (see page 17) For example: M3 3100-2000 To select these functions use the parameter: Timer/Start-up operator mode (see page 35). #t.Mod A Selecting Timer or Start-up, the Soft-start function is disabled, therefore the parameters #st.Op and #st.tM will not be shown. (see page 27) 6.
6 - Special functions continued 6.1 START-UP FUNCTION There are two possibilities: A Start-up Setpoint # s p. s U lower than the local Setpoint. The “Hold” phase starts when the process variable PV achieves the #sp.sU (with a tolerance of 1 digit). B Start-up Setpoint #sp.sU greater than or equal to the local Setpoint. When the process variable PV achieves the local Setpoint (with a tolerance of 1 digit), the Start-up function passes directly to the “Off” phase.
6 - Special functions 6.2 TIMER FUNCTION To use AL3 in addition to this function, set the parameter #Con2 (AL3 configuration code) to # 0.. A The Timer can’t be enabled with Heat/Cool control. The two following parameters (see page 37) must be set to select one of the six possible types of Timer. Timer/Start-up operating mode By this parameter can be defined: - the counting start time - the control output status at the end of the counting #t.
6 - Special functions When the timer is running it is always possible to see the remaining time and to modify it. 850 RUN 850 Operator mode and Timer running Press until 234 RUN If there is a power failure during the Timer execution, the value of the elapsed time is lost. 350 Operator mode 350 Press until Remaining time value stop t.run To start select strt tM.r.

E No control action during the counting time. The time counting starts only when the error is inside a ± 1 digit band. The control action is not affected by the Timer function. The time counting starts when the timer is launched and the control output is forced to zero.At the end, the control action starts. Timer launch #tiMe #t.
