The OUTPUT ALGORITHM lets you select the type of
output you want. Not applicable with Control algorithm
prompt 3PSTEP.
Selections are hardware dependent. For example, if the
controller does not have a current output, then none of the
prompts for Output Algorithms that need a current output
will appear. Likewise, if the controller does not have a
relay output, then none of the prompts that need a relay
output will appear.
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. The signal can be
recalibrated for any desired range from 4 mA to 20 mA for
0 % to 100 % output.
POSITION PROPORTIONAL SIMPLEX—Type of output
using two SPDT relays and a motor which has a 100 to
1000 ohms feedback slidewire.
Forces Input 2 to SLIDEW selection.
ATTENTION Position Proportional is not available on
two-loop or cascade controllers.
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.
