- Maximum counting frequency exceeded
- Signal levels do not reach the switching thresh-
old of the counter
- Factor too small
Output signal missing:
- Wrong output connection
- No ground connection with the following device
Relay output signal missing:
- Output contacts short-circuited
- Output signal (fugitive signal duration) pro-
grammed too short
- Relay contact defective due to too high load
- Relay current below min. value
If, despite all, your device still does not operate,
contact your local representative or call us directly
for technical support.
When sending your device back, please attach a
short description of the failure, of the program-
ming and of the connection diagram, in order to
allow us to reproduce a possibly existing defect
and to repair your device as quickly as possible.
2. Inputs
2.1 INP A, INP B
Counting inputs. Their function depends on the
selected input mode. The maximum counting fre-
quency of 20 kHz can be reduced to 30 Hz by
programming.
2.2 GATE
Static gate input. Function depending on the pro-
grammed operating mode.
Pulse counter mode:
No counting if the input is ON.
Time counter mode:
Counting programmable for input ON (gate.lo) or
OFF (gate.hi). The decimal point of the lowest
decade blinks to indicate that the counting is run-
ning.
2.3 RESET
Dynamic reset input. Resets the counter to zero
when counting up, and sets it to the preselected
value when counting down. The reset input can be
inhibited in the Setup.
2.4 KEY
Static key locking input. The presets cannot be
modified as long as this input is ON. It is how-
ever still possible to switch the display between
the counting value and the presets.
3. Outputs
3.1 Output 1
Potential-free opening or closing relay, or opto-
coupler with open emitter and collector.
3.2 Output 2
Potential-free change-over relay or optocoupler
with open emitter and collector.
3.3 Active outputs
The active output is indicated by a status LED.
The outputs can be reversed in case of safety
circuits, i. e. voltage to the relay coils is cut off or
the optocouplers block when the preset values
are reached.
Caution:
In all modes with automatic repetition (AddAr,
SubAr) the duration of the pulse is to be pro-
grammed for the timed signal of output 2, other-
wise this signal will have no defined duration.
4. Setting of the operating parameters
a.
Press push-button "P" and apply power to
the device.
b.
The display shows the message:
c.
When the push-button is released, the title of
the menu and the current values of its pa-
rameters are displayed in one-second peri-
ods. Press the " " key to interrupt the
scrolling and display only the current param-
eters.
d.
Press the "" key to jump to the following
value of the parameter currently being set.
e.
Press the "P" key to accept the value of the
parameter currently being and switch over to
the following menu item.
f.
The last parameter of the setting menu,
"EndPro" allows, selecting "YES", to leave
the programming menu and to take over (to
save) the new values. If "NO" is selected, the
programming routine starts again from the
beginning, keeping the last input values. They
can then be checked and modified again.
