Input mode (both time meters in common)
Operating mode (both time meters in common)
Reset mode for time meter 1 and/or 2:
electrical
manual
manual and electrical
no reset
2. Inputs
INP A
Stop input (depending on chosen input mode)
INP B
Start/Stop or gate input (depending on chosen input
mode)
RESET
One dynamic reset input and red reset key. Can be
programmed for each timer separately.
3. Setting of the parameters
3.1 Selecting the displayed value
By pressing the right key, it can be chosen whether the
current value of time meter 1 or time meter 2 is displayed.
Pressing the right key once the current function („time1"
or „time2") is displayed for 2 seconds. If within this period
the right key is pressed again, the current function is
changed. The display shows the new current function a
short time.
3. 2 Setting the operating parameters
a. Hold down both keys on front panel and switch on the
supply voltage.
b. The display shows
c. After releasing the keys the display alternates
between menu title and coressponding menu item at
a frequency of 0.5 Hz. After any key is pressed down,
only the menu item is displayed.
d. Pressing the right key, the menu item will be switched
to next value.
e. Hold down the left key and press the right key to
enter and switch to the next menu title.
Electronic Time Meter
with 2 Timers
f. After programming the last menu item, the
programming routine will be left and the new values
will be stored by switching the menu item to „YES".
If you chose „NO", the programming routine will be
passed through once again.
4. Programming routine
Programmable parameters are shown in succession.
After one pass, the device is fully programmed.
In each case the first shown item is the factory preset.
4.1 Input polarity
4.2 Activating the 30 Hz filter
4.3 Input mode time meter
npn: switching to 0 V
pnp: switching to
+V (4-30)
Start/Stop responce
50u seconds
Start/Stop responce
16 miliseconds
Start/Stop via INP B. Timing
while INP B (gate) inactive or
open
Start/Stop via INP B. Timing
while INP B (gate) active
(High level at pnp; Low level
at npn)
Timing will be started and
stopped via INP B (LOW-
HIGH edge at pnp; HIGH-
LOW edge at npn). Every
active edge changes the
timer status.
Timing will be started via
INP A, stopped via INP B
(LOW-HIGH edge at pnp;
HIGH-LOW edge at npn).
