TIME
TIME SIMPLEX—This output algorithm uses Relay 3
for Time Proportional Control. Time Proportional
Output has a resolution of 3.33 milliseconds with an
adjustable Cycle Time (see Section
3.5).
CURRENT
CURRENT SIMPLEX—Type of output using a
milliamp signal that can be fed into a positive or
negative grounded load. This signal can easily be
configured for 4-20 mA or 0-20 mA operation via the
C3 RANGE configuration, below.
TIME D
TIME DUPLEX—This output algorithm uses Relay 1
and Relay 2 for Duplex Time Proportional Control.
Relay 1 is the HEAT output and Relay 2 is the COOL
output. Time Proportional Output has a resolution of
3.33 milliseconds. Time Proportional Output has a
resolution of 3.33 milliseconds with an adjustable
Cycle Time (see Section
3.5).
CUR D
CURRENT DUPLEX—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
CUR TI
CURRENT/TIME DUPLEX—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: OUT2 RNG
TI CUR
TIME/CURRENT DUPLEX—Similar to
CURRENT/TIME 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: OUT2 RNG
OUT2 RNG CURRENT DUPLEX RANGE ALGORITHM—Used
with Output Algorithm selections CUR D, CUR TI, or
TI CUR.
