♦
In some cases,
BTC284U finds
non-conformities
in parameter values
that must be corrected
before operating
at Basic level.
♦
The device indicates
such kind of problems
by displaying
error messages
as given on the left.
♦
If
FAiL
appears
on the display,
try debugging
by turning
the power off/on.
♦
If the problem persists,
press and hold
or
send command
error
0
via the communication
interface to restore
the default (factory)
settings.
Parameter Programming
5
Some parameters
are accessible only
when the respective
functionality is installed.
(see
'
Specifications
'
).
- Changing
Point Position
value
reflects the real value
of all parameters
with ISU.
E.g.: changing
Point Position
value
from (0) to (0.0)
would change
a set-point value
of 100 to 10.0.
Controller parameters
BTC284U is a programmable device whose
service behavior is determined by a set
of parameters. All the parameters, along
with their names, symbols, and value ranges,
are given in Table 1.
Setting numerical parameter value
♦
Enter parameter value adjustment mode
(see '
Program Levels
').
♦
The whole part of the value together with
the left zeroes appears on the display,
and the rightmost digit blinks.
♦
To select another digit, press
.
♦
The 3 rightmost digits can accept values
from
0
to
9
, and the leftmost digit
can also accept the values
-
and
`
.
♦
To increase or decrease the blinking digit
value, use respectively
or
.
♦
Confirm the adjusted value by pressing
simultaneously
+
or
+
.
♦
If the new value has not been confirmed
and no key has been pressed for a certain
period of time, value adjustment
automatically ceases, and the parameter
retains its initial value.
Setting symbolic parameter value
♦
Enter parameter value adjustment mode
(see '
Program Levels
').
♦
Read the blinking parameter value.
♦
To change the value, use
or
,
and to confirm, press
+
or
+
.
♦
If the new value has not been confirmed
and no key has been pressed for a certain
period of time, value adjustment
automatically ceases, and the parameter
retains its initial value.
Program Levels
8
Basic level
At Basic level, BTC284U indicates
the measured input value (PV)
with a resolution, according to
the
Point Position
parameter.
♦
If the whole part of PV cannot be
entirely displayed, the unit
generates blinking 'overflow'
message (
oL
or
-oL
,
depending on PV sign).
♦
If PV is out of its operating range
(the input range according
to Table 1, extended by 5%
on both sides), the device displays
blinking symbolic message:
<__>
(under-range) or
{++}
(over-range).
When PV is out of physical range,
the unit displays
----
.
♦
Upon entering Basic level,
BTC284U may display
the
init
message,
indicating that some time
is necessary for filter initialization.
♦
The
noiS
message may appear
as a result of the peak filter
operation (see '
Input filtration
').
♦
To enter parameter value
adjustment mode for
Set Point 1
,
press and hold
until
%[1
appears on the display.
To view the Set-point value,
release the key.
♦
To enter parameter value
adjustment mode for
Set Point 2
,
follow the same procedure,
but start with the
key.
Program Levels
9
Parametric level
This level contains the control
algorithm parameters. If no relay output
is installed, this level does not show up.
♦
Enter from Basic level by pressing
and holding
until
PAr
appears
on the display. Release the key.
If the key is not released on time,
BTC284U enters Configuration level.
♦
Choose a parameter
using
and
.
♦
To enter parameter value
adjustment mode, press
.
♦
If no key has been pressed
for a while, the device automatically
returns to Basic level, storing all
confirmed changes.
♦
For quick exiting and saving,
use key combination
+
.
Configuration level
This level contains the configuration
parameters of the device.
♦
Enter from Basic level by pressing
and holding
until
conF
appears on the display.
♦
To access and adjust
the configuration parameters,
follow the algorithm described
in 'Parametric level'.
