7.6.6 Open-close duty (REMOTE MODE) and modulating duty (SETPOINT MODE) selection

58
If the end positions cannot be reached due to inaccurate analogue setpoint
signals (0/4 mA or 20 mA), a tolerance for the nominal value within the end
position range can be set. If the tolerance is exceeded or not reached, the
actuator continues the operation until the full end position has been
reached. This ensures that the actuator opens and closes fully.
Information The tolerance ranges are not effective if the operation commands are trans-
ferred to the actuator as fieldbus telegrams. In this case the actuator runs
completely CLOSED as soon as it receives the nominal value 0 % and com-
pletely OPEN as soon as it receives the nominal value 100.0 %.

In standard version, the change-over between open-close and modulating
duty is made via fieldbus (channel 1 or channel 2) using command bits in
the process representation output. Only one command bit may be set at any
one time. No operation is performed if several command bits are set.
SETPOINT MODE command bit = 1 corresponds to modulating duty:
The actuator reacts to the setpoint E1 transmitted via the fieldbus.
Remote OPEN or Remote CLOSE command bits = 1:
The actuator runs in direction OPEN or CLOSE.
.
The following versions also allow a change-over between open-close and
modulating duty via the MODE input (refer to wiring diagram):
.
in addition to the Profibus DP interface, the AUMATIC is equipped with a
further parallel interface (refer to page 83)
the AUMATIC is equipped with additional control inputs (refer to page 80).
MODE input: + 24 V DC = REMOTE MODE = open-close duty, i.e. the
control is executed via commands OPEN - STOP - CLOSE
MODE input: 0 V (or input open) = SETPOINT = modulating duty, i.e. the
control is executed via an analogue signal (e.g. 0/4 – 20 mA)
