Applications
Linking
Recipes may be linked together to form longer, more complicated programs.
Through the selective use of
CYCLES
and
LINKING
, complex recipes with
subroutines can be created.
Events
For each ramp and dwell, 1, 2 or 3 available relays may be opened or closed.
These may be used for a variety of purposes to include starting and stopping
other process equipment. Upon recipe completion, events may be held until
released by the operator (using
FAST + ACK
).
Programming recipes requires the user to make selections in the
REC.
CONF.
menu of the
SET UP
mode before programming the actual recipes.
Software Configuration
The controller must be configured for the profile option before
accepting recipes:
1. Enter the
SET UP
mode. Select the
REC. CONF.
menu.
2. The first parameter is
RECIPES
. This parameter defines the number of
recipes available in the 535. Choices are:
D
1
R
1 through 20
3. The next parameter is
TIME BASE
. It defines whether recipes are timed in
hours and minutes or in minutes and seconds. Choices are:
D
HOURS:MIN
•
MIN:SEC.
4. The next parameter is
RAMP UNIT
. It defines the times unit for ramp seg-
ments (hours:min or min:sec) or rate of change required to reach setpoint. If
TIME BASE
=HOURS:MIN, the ramp unit will be in PV units per minute. If
TIME
BASE
=MIN:SEC the ramp unit will be in PV units per second. Choices are:
D
TIME
•
RATE
5. The next parameter is
SP START
. It selects whether the first ramp
segment’s setpoint must start at the IDLE setpoint or if it can be adjusted to
account for the initial PV value (thus allowing the ramp segment to be short-
ened). Choices are:
•
IDLE SP the IDLE SP will be the starting setpoint of the first ramp
segment
•
PV the first ramp’s starting setpoint can be adjusted
6. The next parameter is
GUAR.SOAK
. It selects whether the guaranteed soak
feature will be used. Its choices are:
D
OFF guaranteed soak will not occur
•
START SEG. guaranteed soak can occur only at the start of a soak segment
•
WHOLE SEG. guaranteed soak can occur at the start of or at anytime during
soak segment
7. The next 3 parameters are
EVT.:1 OUT, EVT.:2 OUT
and
EVT.:3 OUT
.
These select which outputs are assigned to each events. Choices are:
D
NONE
•
2
•
3
