20 RECIPES/PROGRAMS
Up to twenty (20) recipes/programs may be stored in memory
and recalled by number through the front panel keys, digital
inputs or RS-485 communications.
24 SEGMENT PER RECIPE
Twelve (12) ramps and twelve (12) dwells may be programmed
for each recipe. Programming a dwell time of OFF effectively
skips the dwell allowing two (2) consecutive ramps of different
rates. Recipes may be link if more than twelve (12) segments
are necessary.
GUARANTEED SOAK WITH ADJUSTABLE HYSTERESIS
When activated, dwell time doesn't start until the ramp setpoint
has been achieved within the specified hysteresis (a positive or
negative deviation from the dwell setpoint).
3 EVENT OUTPUT CAPABILITY
Up to three (3) event outputs, programmable per segment, may
be selected depending on the availability of controller outputs.
The 535 has four (4) outputs; if one is used for control, three are
available for events. Likewise, if one is used for control and one
is used for alarm, two are available for events. These outputs
are available for turning on fans, starting other processes, or
performing other functions.
RAMPS PROGRAM IN TIME OR RATE
A ramp can be programmed to take place over a specific
amount of time or be based on the rate of change of the PV per
time unit. If time based, the time to reach setpoint must be
between 0:01 and 99:59 (minutes:seconds or hours:minutes). If
rate based, the setpoint must be reached at a rate between –
9999 and 99999 engineering units per second or per minute.
DUAL TIME RATE
Two modes are available—Hour:Minutes or Minutes: Seconds.
MULTIPLE CYCLES, 1—99 PER RECIPE
Recipes may be programmed to automatically repeat up to
99 times or continually.
RECIPE LINKING
All twenty (20) recipes may be linked to form a new longer
version. For example, select recipe 4 to automatically
follow recipe 2.
REMOTE FUNCTIONS VIA DIGITAL INPUT
Using the optional digital inputs, the following functions may
be remotely activated: Start, Hold, Reset, Abort and
Segment advance.
MODIFY RECIPES WHILE RUNNING
Individual recipes may be modified by the operator while
running.
REMOTE RECIPE CHOICE VIA DIGITAL INPUT
Using the optional digital inputs, recipes 1 through 7 may
be selected remotely,.
POWER RESTORATION MODES
Four different power restoration modes are available.
Upon Power failure and subsequent return, the controller
can either 1) resume a recipe where it left off; 2) return to
the last output of the recipe and hold it; 2) Abort the recipe;
4) Start a new recipe automatically
TIE PID SETS TO RECIPES OR SEGMENTS
Any one of eight PID sets may be tied to each recipe or
segment to optimize control.
MASTER/SLAVE CAPABILITY
The 535 with profile controller option can retransmit the
ramping setpoint to up to four 535s with remote setpoint
creating a master/slave relationship.
With this capability, five (5) loops, each running the same
recipe, can be controlled.
SEGMENT ADVANCE
The operator may advance thought the program segments
while a recipe is running.
