6.6.8 Set up 1 – Hold
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 38, digital input E1). The on-site hold has a higher priority than an external hold.
!
Note!
• Hold is active when the assembly moves into the maintenance position.
• When hold is active, no new automatic programmes are started.
They can be started externally or via local operation as required.
• You can deactivate the Topclean S as hold source

Freeze actuating variable (dosing) :
On : During an active hold, the last set value is output.
Off : 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 actuator drive with feedback, the actuator remains
active. It also reacts in the hold should the position suddenly change.
