8.3.2 Parameters: Limits
Two limits are assigned to each component, and can be set
using this menu. A relay is triggered when the limits are violat-
ed (see section Configuration: Inputs/outputs/pump: Assign
relays (Page 138)). Limit 1 is the lower limit, Limit 2 the upper
limit.
Note
A set limit only triggers a relay contact if a relay has previously been assigned to the
corresponding limit signal (see section Configuration: Inputs/outputs/pump: Assign relays
(Page 138)). The limits are not updated:
• During the first warm-up phase
•
During an AUTOCAL
• During the message: Function control and analog output at 'Hold measured value' (see
section Configuration: Inputs/outputs/pump: Analog outputs (Page 134))
If you have selected "Limit 1" or "Limit 2", a menu display ap-
pears in which you can enter the lower or upper limit for each
component. You can define the value in the second line, and
the condition under which a contact is be triggered in the third
(Alarm at conc.:):
•
High: with upward violation
•
Low: with downward violation
•
- - - - -: no signal.
