Table 11: Counter modes
Wiring of a counter
You integrate a counter into your circuit in the form of a
contact and coil. The counter relay has different coils.
EZ circuit diagram with counter relay
The coils and contacts have the following meanings:
Counters Mode
C1 to C12 N Up/down counters
C13, C14
N or H Up/down counters or
high-speed up counters
(EZ-DA, EZ-DC)
C15, C16
N or F Up/down counters or
frequency counters
(EZ-DA, EZ-DC)
J
To prevent unpredictable switching states, use each coil of
a relay once only in the circuit diagram.
Do not use the input of a high-speed counter as a contact in
the circuit diagram. If the counter frequency is too high only
a random input value will be used in the circuit diagram.
I5-------CC2
I6-------DC2
I7-------RC2
C2-------SM9
Contact Coil
C1 to C16 The contact switches if the
actual value is greater than or
equal to the setpoint.
