Time meter CXG 23
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 pro-
gramming the display guides the user with text
prompts.
• Optocoupler output (optional). At active count-
ing the output alternates at 1 Hz between
active and inactive.
• Programmable features:
Input polarity (npn or pnp)
Input mode
Operating mode
Reset mode
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
Dynamic reset input. Linked to the red reset key.
3. Optocoupler Output
On active counting the output alternates at a fre-
quency of 1 Hz between active and inactive.
4. Programming routine
Programmable parameters are shown in succes-
sion. After one pass, the device is fully pro-
grammed.
In each case the first shown item is the factory
preset.
4.2 Activating the 30 Hz filter
Start/Stop inputs: normal
operation
Start/Stop inputs:
damped, e.g. when using
mechanical switches
Start/Stop via INP B.
Counting while INP B
(gate) inactive or open
Start/Stop via INP B.
Counting while INP B
(gate) active (High level at
pnp; Low level at npn)
Counting will be started
and stopped via INP B
(LOW-HIGH edge at pnp;
HIGH-LOW edge at npn).
Every active edge
changes the counter sta-
tus.
Counting will be started
via INP A, stopped via
INP B (LOW-HIGH edge
at pnp; HIGH-LOW edge
at npn).
4.3 Input mode time meter
