5.14 Detection Loops
This menu selection allows you to:
 define the name of a detection loop
 override the system calculated preset current
 set a different limit for the maximum possible loop current for a
selected detection loop.
The following different default settings are possible: 100mA,
150mA, 200mA, 250mA, 300mA, 350mA and 400mA.
Note that the high current settings 300mA, 350mA and 400mA are
only available with BSA-200A or BSD-200A (revision A required).
Due to limitations of the power supply, the system will not allow
configuration of a total loop current exceeding 1200 mA.
When the system is powered up, or the loop driver is enabled, the
system will automatically calculate and set a current limit which is
optimized for each loop individually, depending on the number and
type of loop units. If the operator has configured a maximum loop
current value being higher than the system preset value, this
value will not be changed by the system.
In some cases the system may allow the operator to override the
system preset loop current and decrease the maximum loop current
to a value being 50 mA lower the preset loop current. This should
only be used if the system reports a fault on the loop resistance
being too high. Overriding and decreasing the preset loop current
with 50 mA may be sufficient to avoid this fault.
 The maximum power consumption is determined by the following
parameters:
o the number of loop units
o the loop unit type, i.e. the specified maximum current for the
loop unit type
From the Service Menu, perform the following:
 Use the arrow down button to scroll downwards to
Unit Configuration, then press Enter.
 Use the arrow down button to select Detection Loops, then
press Enter.
 Use the arrow up/down buttons to select the Detection Loop
that is to be configured, then press Enter twice.
 Type a new Name, or accept the existing one by pressing
the arrow down button.
 Press Enter, use the arrow left/right button to select (if allowed by
the system) if the preset loop current shall be overrided,
then press Enter.
 Press Enter, use the arrow left/right button to set the limit for
maximum loop current, then press Enter.
 To confirm, press Enter once more.
