Function Description 

 

The timer is always equipped with two output contacts and a buzzer. 

 

 

Derivative

time TA1

START

K1 on

K1 off

K2 on

Buzzer on

END

K2 off

Buzzer off

Derivative

time TA2

Operating

time t1

Operating

time P15

 

 

The entire process consists of the following successive phases: 

- Derivative time TA1 for relay K1 (relay K1 is still inactive) 

- Active phase t1 for relay K1 

- Derivative time TA2 for relay K2 (the relay K2 is still inactive) 

- Active phase P15 for relay K2 (possibly together with the buzzer) 

 

The timer is started with key 4 or switching input E1 (see parameter P10). 

Stop the timer at any time with key 5 or switching input E2 (see parameter P11). 

 

The start and stop functions via the switching inputs are edge-controlled, only a change of state in the right 

direction (see parameters P5 or P6) leads to an action. The most recent command is effective. 

 

Please note that the buzzer function (if activated with P9) is not necessarily connected to the output K2. The 

buzzer sounds at the end of the timer or at the end of P15, but is active at one of the special functions (P16 = 

1) regardless of K2. 

 

 

Timer and display 

 

As for the operating time t1 it is possible to display the time remaining or the elapsed time (see parameter 

P12). As for the derivate times, always the respective remaining time is indicated. 

 

If an acknowledgment for K2 provided (see parameter P13), it is indicated until acknowledgment after the 

timer has elapsed. 

If time ranges with colon are selected, the colon is flashing during the timer. For the flashing frequency the 

following applies: 

-  During the active phase of the relay K1 the colon flashes every second. 

-  During the derivate times and during the active phase of the relay K2 the colon flashes with in-

creased frequency. 

-  When the timer has elapsed the colon stops flashing and remains lit continuously. 

 

It is possible to specify a continuous mode, in which all phases are automatically restarted. 

 

It can be selected (see P17) if the display returns at Stop and after acknowledgment of the set time t1, or 

remains on the respective past value in the display mode. 

 

After the timer stops and after an acknowledgment the display can show again the operating time t1 or the 

respective elapsed timer value is indicated, depending on parameter P17.
