The OUTPUT ALGORITHM lets you select the type of output you
want. Not applicable with Control algorithm prompt 3PSTEP.
Selections are hardware dependent.
ATTENTION For all Duplex Output forms, PID heat parameters
apply for controller output greater than 50 %; PID cool parameters
apply for controller output less than 50 %.
TIME SIMPLEX—This output algorithm uses Digital Output 1 for
Time Proportional Control. The output is updated per the Loop
sampling rate selection. Time Proportional Output has a resolution
of 4.44 msec. Cycle Time is adjustable from 1 to 120 seconds.
CURRENT SIMPLEX—Type of output using one 4 mA to 20 mA
signal that can be fed into a positive or negative grounded load of 0
to 1000 ohms. This signal can easily be configured for 4-20 mA or
0-20 mA operation via the CO RANGE configuration, below.
POSITION PROPORTIONAL—Type of output using two relays
and a motor that has a 100 to 1000 ohms feedback slidewire.
This output algorithm selection forces Input 2 to the SLIDEW
selection when the Control Algorithm is any selection other than
3PSTEP.
ATTENTION Other prompts affected: DEADBAND, IN2 TYPE
TIME DUPLEX—This output algorithm uses Digital Outputs 1 and
2 for Duplex Time Proportional Control. The outputs are updated
per the Loop sampling rate selection. Time Proportional Output has
a resolution of 4.44 msec. Cycle Time is adjustable from 1 second
to 120 seconds.
CURRENT DUPLEX is similar to current simplex but uses a
second current output. The second output is usually scaled so that
zero and span correspond with 0 % and 50 % output (cool zone).
When the output is 0 % to 50 %, the controller uses tuning
parameter set #2, when the output is 50 % to 100 % it uses set #1.
ATTENTION Other prompts affected: OUT RNG
CURRENT/TIME DUPLEX is a variation of duplex with current
active for 0 % to 50 % output (tuning set 2) and time is active 50 %
to 100 % output (tuning set 1).
Relay controls heat, current controls cool.
ATTENTION Other prompts affected: OUT RNG
TIME CURRENT DUPLEX is similar to CUR TI except that current
is active for 50 % to 100 % and time is active for 0 % to 50 %.
Relay controls cool, current controls heat.
ATTENTION Other prompts affected: OUT RNG
CURRENT DUPLEX RANGE ALGORITHM — Used with Output
Algorithm selections CUR D, CUR TI, or TI CUR.
