1. Operation of the front keys
To enter the setup mode, keep both front keys down while you switch power on.
You can also enter the setup mode when the unit is already powered on, by keeping both front
keys down at the same time for approx. 5 seconds.
The display will then show
As soon as you release the keys, the display starts to alternate between the actual parameter
text and the associated setting, in a cycle of two seconds.
Press the key on the right to increment the actual set value to next.
For numeric entries, use the left key to select the decade and the right key to scroll the value.
To continue to the next parameter, keep the left key down while you press the right key.
When you have reached the item „Endprog“, you get the choice
−„Yes“: this will store your entries to the unit and switch to normal operation.
−„No“: this will start the menu again and your previous data will not be stored.

2. Operational parameters
Please enter all of the subsequent parameters, like shown in section 1.
2.1. Input polarity
InPol
nPn NPN: The count input must switch to“0“
PnP PNP: The count input must switch to “+“.
Namur: Set to NPN. See section 3.
2.2. Input filter
Filter
oFF Filter off: maximum input frequency 60 kHz
On Filter on: maximum input frequency 30 Hz
2.3. Scaling factors
Factor
00.0001 Multiplies the input frequency with the factor
setting.
99.9999 Range 0.0001 to 99.9999.
Setting “0“ will not be accepted.
Divider
00.0001 Divides the input frequency by the divider setting.
99.9999 Setting range 0.0001 to 99.9999.
Setting “0“ will not be accepted.
2.4. Decimal point
dP
0
0.000
Adjustable between no decimal position and max.
3 decimal positions. This setting does not affect
the numeric value of the frequency display.

DX02002b_e.DOC / Jan-08 Page 6 / 9
2.5. Display mode
diSPm
Sec -1 The unit displays the frequency as number of
impulses per second (Hz). (With factor setting
1.0000)
Min -1 The unit displays the frequency as number of
impulses per minute. (With factor setting 1.0000).
2.6. Maximum waiting time
WAit0
01.1
99.9
This setting specifies the maximum waiting time
from one input impulse to the next, before the
display sets to zero.
Range 1.1 sec to 99.9 sec
2.7. End of program
EndPro
No Select “No“ to return to the beginning of the menu
for verification of settings.
YES Select “Yes“ to store data and exit the menu.
