8.1 CONFIGURATION PROTECTION
As a safety measure, changes can be prevented by a combination of keys for each cycle Parameters
can be seen but not changed.
To protect a cycle just press the and keys simultaneously for 3 seconds at the beginning
of the referred cycle
To unlock this cycle (and allow for changes) just press the and keys for 3 seconds.
Displays will flash briefly to confirm locking or unlocking operation.
Within the controller, the PROT key completes the locking function. When PROT is OFF the user is
allowed to lock and unlock the cycles. When PROT is ON changes are not allowed. if cycles are
protected, protection cannot be removed, if there aren’t cycles protection, they cannot be made.
9 PROGRAMMING THE INDICATOR
9.1 WORK CYCLE
This is the first cycle. At power up the indicator will display the Process Variable (PV). The alarm
triggering points are also displayed at this cycle (alarm Setpoints). To advance in this cycle simply
press
.
TELA PROMPT PARAMETER DESCRIPTION
8.8.8.8.8. Measure prompt - Shows the variable measured according to the limits
defined in the “in.LoL” and “in.kiL” prompts.
If the Hold function is programmed, the display shows the frozen variable
measure alternating it with the “koLd” message.
If the Peak Hold function is programmed, the display shows maximum
variable measured alternating it with the “P.koLd” message.
Should any failure occur, the indicator will display an error message, which is
described in item 11 of this manual.
Al.ref Differential Alarm Reference Value - This prompt is shown only when there
is an alarm programmed with differential function. This value is used as a
reference for differential alarms triggering.
Sp.al1
Sp.al2
Sp.al3
Sp.al4
SP of Alarms 1, 2, 3 and 4 – Value that defines the alarms triggering points
programmed with “Lo” or “ki” functions.
Note: For alarms programmed with differential functions, the alarm SP value
can not be changed, and the “diF” message is displayed. The value of
differential SP (deviation) is defined in the Alarms Cycle.
NOTE: The SP adjustment parameters are presented only if the corresponding
alarm function is configured.
