Ter- Function
minal
1 10-30 V DC,
Supply voltage +Ub
2 GND, 0 V DC
3 GND, 0 V DC
4 INP PNP, the timer starts counting when a
voltage > 3.5 V is applied to terminal 4
input.
5 INP NPN, the timer starts counting when a
voltage < 2 V is applied to terminal 5 input.
RESET MANUEL ENABLE,
6
Reset key and Reset input enable input
(terminal 7): when terminal 6 is connected
to GND (< 2 V), the key or the Reset input
(terminal 7) allows resetting the blinking
display and the output (terminal 8)
RESET,
7
Reset input: when terminal 7 is connected
to GND or to 0 V (< 2V), the key or the
Reset input (terminal 7) allows resetting
the blinking display and the terminal 8
output. The display shows for 4 s the new
preselection value and then switches to
the current counter value. If the Reset
input (either the key or the terminal 7 in-
put) is activated within these 4 s, the coun-
ter is reset to its factory setting (dynamic
input).
OUT
8
Output: when the service value is reached,
the output is activated (NPN output, Open
Collector).
Output voltage max. 30 V,
Output current max. 50 mA.
Output circuit
Terminal 8: output, only
for Codix 143
Terminal 2 or 3
3.2.2.1 Functions of the front key
When the Reset key is enabled, the Reset is trig-
gered when the front key is released, or with the
rising edge of the Reset input on terminal 7. The
device is reset immediately to the factory setting
when the key is depressed again or at the second
negative edge on terminal 7.
Display and reading mode
When the Reset key is not enabled by means of the
activation input on terminal 6, depressing the key
allows the user to call up the following functions.
Depress 1x:
The display shows the message "SErViCE"
Depress 2x:
The display shows the next service value
Depress 3x:
The display shows the message "PrESErVv
Depress 4x:
The display shows the next pre-service value
Depress 5 x
The display shows the current counter value.
