Hold function = "Freezing the outputs"
The current outputs can be "frozen" for each menu. This means that the value which you
define in this menu is output. With hold, "Hold" appears in the display.
The hold function can also be activated externally via the hold input (see wiring diagram
on page 15, digital input E1). The on-site hold has a higher priority than an external hold.
!
Note!
•
If a hold is active, no programme can be started.
If current output 2 is configured for the controller, it complies with the controller hold (see
Field I5).

Controller hold
Freeze actuating variable (dosing) :
Yes
: During an active hold, the last actuating variable is
output.
No
: During a hold, no dosing takes place. PWM or PFM
relays remain in the dropped-out state. An actuator
drive is controlled until it is closed.
!
Note!
If the set value is output via an actuating variable with
feedback, the actuator remains active. It also reacts in
the hold should the position suddenly change.
