9.4.7 Parameter Menu "Digital outputs“
Fig. 9-43
Relay selection menu
This menu allows to select between relays 1-5 using the >right< or >left< arrow
keys.
Relays 4 (close slide valve) and 5 (open slide valve) are dedicated to regulator
functions if the regulator has been enabled. It is not possible to modify this
assignment!
Select parameter “relay function” to indicate available functions.

Relay outputs – submenu
Limit flow rate
Relay will energise if a flow limit value (to be set) has been exceeded and will
de-energise if flow falls below a second limit value (to be set).
Limit level
Relay will energise if a level limit value (to be set) has been exceeded and will
de-energise if level falls below a second limit value ( to be set).
Limit velocity
Relay will energise if a velocity limit value (to be set) has been exceeded and
will de-energise if velocity falls below a second limit (value to be set).
Limit temperature
Relay will energise if a temperature limit value (to be set) has been exceeded
and will de-energise if medium temperature falls below a second limit (value to
be set).
Volume impulse pos.
Relay will output volume-proportional impulses if the flow direction is positive.
Weighting and impulse duration are free programmable
Volume impulse neg.
Relay will output volume-proportional impulses if the flow direction is negative
(= backwater). Weighting and impulse duration are free programmable.
Error signalling
Error message output via relay. >Error input screen< can be selected as soon
as this parameter has been activated.
Error input screen
It is possible to assign the relay output to the respective error here.
