START / STOP
Definition of the start / stop type of the time measurement
COUNT AT A HIGH
Time measurement is active as long as input A is "HIGH"
COUNT AT A LOW
Time measurement is active as long as input A is "LOW"
START A / STOP B
Rising edge on input A starts the time measurement, rising edge on
input B stops the time measurement�
PERIOD AT A
Period measurement: indicates the duration cyclically between two
rising edges at input A�
AUTO SET / RESET
NO
Time measurement adds values up, no automatic reset during the next
start� Zero must be set via set/reset�
YES
With each start, the new time measurement starts automatically at the
set value of the SET VALUE parameter
LATCH FUNCTION
NO
The lapse of time can be seen in the display�
YES
The final result of the last time measurement is displayed while the new
measurement is running in the background�
SET VALUE
A set/reset command sets the timer to the value set here�
0
Lowest value (reset)
…
99999999
Highest value
INC / DEC MODE
With the setting period measurement as START / STOP the time measurement is always incrementing�
INCREMENT MODE
Time measurement is incrementing�
DECREMENT MODE
Time measurement is decrementing�
TOTAL TIME MODE
Activation of the total timer�
If TOTAL TIME MODE is activated, the total timer can be assigned to each PRESELECTION value via the
source�
Example:
For total time measurement, TOTAL TIME MODE must be set to YES� Total time measurement and
normal time measurement then run in parallel� If total time is to be automatically reset to 0 when reaching
1:30 (H:M), the source has to be set to TOTAL TIMER, the respective preselection value to 1:30 and the
respective switching condition to RESULT>=PRES->0� For example: SOURCE 1 of PRESELECTION 1
MENU to TOTAL TIMER, the respective preselection value (in this example: PRESELECTION 1) to 1:30
and the respective switching condition (in this example: MODE 1) to RESULT>=PRES->0�
NO
Total time measurement deactivated
YES
Total time measurement activated
