7: reset coil C..RE
8: contact (make contact) C..OF upper setpoint value reached,
exceeded
9: contact (make contact) C..FB lower setpoint value reached,
undershot
10: actual value equal to zero
11: out of value range
• Range A:
– The counter has the value zero.
– The contacts C..ZE (actual value equal to zero) and C..FB
(lower setpoint value undershot) are active.
– The counter receives counter values and increases the actual
value.
– C..ZE drops out as well as C..FB and also when the lower
setpoint value is reached.
• Range B:
– The counter counts upwards and reaches the upper setpoint
value. The “upper setpoint value reached” contact C..OF
becomes active.
• Range C:
– The coil C..SE is briefly actuated and the actual value is set to
the preset actual value. The contacts go to the respective
position.
• Range D:
– The counting direction coil C..D_ is actuated. If counting pulses
are present, downward count is initiated.
– If the lower setpoint value is undershot, the contact C..FB
becomes active.
• Range E:
– The reset coil C..RE is activated. The actual value is set to zero.
– The contact C..ZE is active.
• Range F:
– The actual value goes outside the value range of the counter.
– The contacts become active according to the direction of the
values (positive or negative).
