ROGRAMMING
3.1.1 Preselections 1 (P1) and 2 (P2)
Key:
F1
for preselection 1 (P1)
F2
for preselection 2 (P2)
P1 may be interpreted either as absolute or relative value (see para. 3.3,
system parameter F20).
P2 is the main preselection by means of which an automatic reset is initiated in
the counter, provided that it had been programmed accordingly (see para. 3.3,
system parameters F4).
As soon as the count reaches the programmed value of P1 or P2 (via counting
pulses counted upwards or downwards), the respective relay switch
Out 1 or
Out 2 (Out 1 is reset by P2).
3.1.2 Set value (SET)
Key:
+
F1
In case of a reset the count of the counter will be set to this value (via
keyboard, terminal or automatically).
3.2 Display parameters
Key:
+
F2
The parameter last modified is the active one: prescaler (prescaler, indicator
PSC
) or decimal point. By briefly pressing the store key
you may switch
back and forth between the two parameters.
To return to the counting mode either
−
press the store key
longer than 2 seconds or
−
it is performed automatically approx. 15 seconds after having last actuated
any key (modified parameters will not be saved)
A reset is always performed.
3.2.1 Prescaler (PSC)
Values must be entered as described in para. 3.1.
By means of the prescaler the number of counting pulses (= encoder pulses
∗
edge evaluation) may be converted in such a way, that the count will be dis-
played in the required unit. A residual value processing is not performed.
