Display indication
The different controller models display programmer status
information in different ways.
The following examples show how the same information is
displayed on the 850, 1650, and 1850 controllers.
Compared to the model 850, models 1650 and 1850 also
show the process variable value (PV_1 PROG.STATUS_1
and PV_2 PROG.STATUS_2).
Compared to the other two models, the model 1850 also
shows the setpoint value of the active step.
1. Indication of programmer status. When on, programmer
is on.
2. Number of program running (number 2 in example).
3. Number of program step running (number 5 in example).
4. LED RUN: on indicates that program is running; flashing
indicates that program is in STOP, END or HOLD, and
that the time base is stopped.
5. LED RAMP: on indicates that program is running the ramp
segment of the step; off means that it is in the hold
segment of the step or at end of program (in example:
running ramp of step 5).
6. Current time of segment (ramp or hold) of step. The time
value depends on the set base times, hh:mm or mm:ss
(in example: elapsed time is 20 minutes and 42 seconds).
7.
Process variable PV_1 or PV_2 depending on whether
you are in PROG.STATUS_1 or in PROG.STATUS_2
(in example: 118).
8.
Setpoint of current step, i.e. the value to be reached
(in example: 120).
