4.6.3 Aggregate modules (direct relay actuation)
Up to 5 aggregate modules can be pre-programmed, thereby influencing the switching behaviour
of specific relays and the connected hardware (
aggregates
). The configuration determines which
nominal values may be entered and they can vary depending on the system. For example an
aggregate can be simply switched on or off, or the interval times of a clocking relay can be
changed
Item 6.1.4, Optional nominal values MKA 500, p. 21
Item 6.2.4, Optional nominal values MKA 800, p. 22
The names for the aggregate modules shown in standby, operating and programming mode are
generated from the relay names.
Current interval times for the aggregate modules are shown during operation:
Depending on which switching behaviour has been configured by the service technician, different
nominal value will be available to the end user in standby, operating and programming mode.
During operation the current actual value and the current nominal value is shown. If you have set
a switch-on interval and a switch-off interval for an aggregate module, the interval times will be
shown alternately in the actual value display.
The status of the aggregate module button (
without delay)
is shown on the button.
Be aware
If a nominal value is changed during operation via VisuNet, the display will be updated
(reset).
4.6.4 Optional control loops
Up to 6 optional regulators can be programmed. The configuration determines which nominal
values may be entered and they can vary depending on the system. In this way the end user
has the option of programming the nominal values of these regulators for the different program
steps.
Be aware
The configuration determines the significance of the nominal values of the individual
regulators.
If additional control loops or additional sensors have been configured for the process that is
currently in operation, their current temperature values (
actual values
) will be displayed.
