Programmable stage
The manager has eight identical programmable stages
(PROGRAMMABLE STAGE 1-8). All programmable stages can
be enabled or disabled one by one from the menu to fit the
intended application. All the enabled programmable stages
have the following programmable parameters:
•
Link: link to a measured or calculated value, see table
below.
•
Cmp: mode (< or >)
•
Pick-up: alarm limit of the stage (the setting range and the
unit depend on the signal)
•
t: operation delay 0.08 - 300.0 s, step 0.01 s or 0.02 s
•
Hyster: hysteresis 0.2 – 10.0%, step 0.1%
•
NoCmp: no compare limit (visible only for active < mode)
