4. Operation of the System
In addition, this menu also provides the same function as the “relay outputs” menu, which can
be accessed through the menu or through the list in the “Setup” window.
The behaviour of a relay output depends on its parameter settings and the settings of
the appropriate measure points
(see section 6.4.2 Behaviour of the Relay Outputs).
Figure 4-26: Relay output assignment menu
The functions for the individual menu items are described below:
Output number
Field type: Selection field
This field contains a list of the physical available relay outputs. Futher the relay outputs who
are no more physical available whose parameter however are stored in the system yet are
contained. The latter can be remove from the selection only then when the user cancel the
field.
After an output number is selected, the rest of the menu is filled, if settings have already been
entered for that output. If an output number is selected that has not been configured before, the
settings from the last displayed output remain and are used as the preliminary settings for the
new output. This makes it easy to copy the settings from one output to another. If an output is
displayed that has not yet been configured, default values are used as the preliminary settings
for the input of certain fields.
This input field can be accessed without a key switch or password if an output is entered for
which parameters have already been set. If a number is entered that has not been used before,
authorisation by means of password or key switch is required.
When first opened, the field contains the relay output that was last selected in the “Measure
point” menu.
All parameter changes using the menu items described below apply to the relay output
selected in this field.
Normal (energised)
Field type: Selection
Set the operating mode for the selected relay output:
ON Normal running is ON
When having been set, the relay driver output gives out a LOW signal (normally energised)
OFF Normal running is OFF
When having been set, the relay driver output gives out a HIGH signal (normally deenergised)
