Parameter Definition
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 Proportion 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 Three
Position Step.

Deadband, Input2 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 3 msec. Cycle Time
is adjustable from 1 second to 120 seconds.
Current Duplex It 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.

Current Time 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,
