OPEN CLOSE CONTROL
Figure 16:
.
Conventional control of the actuator is possible either in OPEN - CLOSE
duty or in modulating duty (setpoint of 0/4 – 20 mA). Selection between
open - close and modulating duty is made via the MODE input (refer to
page 58).
.
Operation commands can be issued via the fieldbus or via the external
inputs. Switch-over is made via BUS/REMOTE input (see below).
OPEN CLOSE ESD
Figure 17:
.
Actuator control is possible in open-close duty (OPEN - CLOSE - EMER-
GENCY) only. Modulating duty is not possible.
.
Operation commands can be issued via the fieldbus or via the external
inputs. Switch-over is made via BUS/REMOTE input (see below).
.
Operation commands are made in push-to-run operation only.
.
If a voltage of 0 V is present at EMERGENCY input, the actuator per-
forms the programmed EMERGENCY operation, irrespective of the
BUS/REMOTE input.
