Together with the possibility of various parameters, two output contacts and two switching inputs
will allow the employment of any applications one can think of. The timer can be started and
stopped both with the front buttons and with the switching inputs.

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

Adjusting the operating time
By pressing th SET-key the operating time t1 is indicated.
By additionally pressing the UP- or DOW N-key the time can be set.
Second control level (P-parameter):
Adjusting of timer parameters
Simultaneously pressing the UP and DOWN key for at least 4 seconds opens an intermediate menu with
“PA0” in the display.
If there is no password specified for access to the actual parameter list (= factory setting), a short press of
the SET key opens the timer parameters, starting with P1
With the UP and DOWN keys the list can be scrolled in both directions.
Pressing the SET key will give you the value of the respective parameter. Pressing also the UP or DOWN
key at the same time the value can be adjusted.
Return to the initial position takes place automatically, if no key is pressed for 60 seconds, or by simultaneously pressing the UP and DOWN key for approx. 4 seconds

Parameter description
P1: Operating range K1
There are three operating ranges available: seconds (with 1/10 of a second), minutes/seconds, and
hours/minutes.
P5: Function input E1
“Start with closed contact” means that closing the switching input E1 starts the timer.
“Start with opened contact” means that opening the switching input E1 starts the timer.
P6: Function input E2
Same function as parameter P5, regarding the Stop function.
P7: Function output K1
P8: Function output K2
The setting “activated during timer” means the respective relay is closed (energized) during the timer. In the
remaining time it is opened (de-energized).
The setting “deactivated during timer” means the respective relay is opened during the timer. In the remaining time it is closed.
P9: Buzzer function K2
The buzzer can be activated together with the relay K2. It sounds continuously or intermittently.
With the parameter setting P16 = 1 the buzzer sounds independently of the output K2.
P10: Trigger start
The start function can be triggered either by the switching input E1 and/or by the key 4.
This is regardless of the trigger of the stop function.
P11: Trigger stop
The stop function can be triggered either by the switching input E2 and/or by the key 5.
This is regardless of the trigger of the start function.
P12: Display mode operating time t1 (K1)
With the setting “countdown” the current time goes from t1 to 0.
With the setting “elapsed time” the current time goes from 0 up to t1.
P13: Stop of timer K2
0: There is no specific operating time for K2; K2 is active until pressing the STOP key
1: Same as “0”, but it’s possible to do a restart without previous stop.
2: Operating time in parameter P15 will take effect; after its expiration the timer stops.
3: Operating time in parameter P15 will take effect; after its expiration the timer restarts. The timer is now in
continuous operation until a manual stop.
P14: Operating range K2
There are two operating ranges available: seconds (with 1/10 of a second) and minutes/seconds.
1: both relays as K1, K2 inactive
during timer
2: both relays as K2, K1 inactive

P16: Special functions
For special use cases it is possible to activate both relays during the operating time t1 (then inactive during
P15) or vice versa.
Please note that the buzzer is linked to the final sequence stop, i.e. to P15. If P16 = 1 it will sound regardless
of the output K2.
P17: Display after Stop and buzzer acknowledgment
With P17=1 the display shows the operating time 1 after Stop or acknowledgment of the buzzer.
