Time meter Type series 523
1. Description
• 6digit time meter, resetable
• LED-Display with 8 mm high characters and very
high luminosity
• Display range 0..999999 with leading zero blanking.
• Programming of count functions and operating
parameters via the setting keys. During programming
the display guides the user with text prompts.
• Optocoupler output (optional). At active counting the
output alternates at 1 Hz between active and
inactive.
• Programmable features:
Input polarity (NPN or PNP)
Max. count frequency (30 Hz or 10 kHz)
Input mode (both time meters in common)
Operating mode (both time meters in common)
Reset mode for time meter 1 and/or 2:

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
Dynamic reset input. Linked to the red reset key. Can be
programmed for each counter separately.
3. Optocoupler Output
When timing the output alternates at a frequency of
1 Hz between active and inactive.
3. Setting of the operating parameters
a. Hold down 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 corresponding menu item at a frequency of

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.
f. After programming the last menu item, the programming

4. Programming routine
Following all 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 +24 V
max. count frequency
10 kHz
max. count frequency
30 Hz
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).
