Operating Instructions Temperature Indicating Controller CS4H / CS4L
V1.1 • 05/2006 - 19 -
5.2 Main setting mode
If the MODE key is pressed, main setting mode is selected.
The setting value (numeric value) can be increased or decreased by pressing the
▲
or
▼
key.
If the MODE key is pressed, the setting value is registered and the controller will revert to the PV/SV
display mode.
SV1 [ ]
• Sets SV1.
• Setting range: SV low limit to SV high limit or
Scaling low limit value to Scaling high limit value
• Default: 0 °C
SV2 [ ]
• Sets SV2.
• Setting range: SV low limit to SV high limit or
Scaling low limit value to Scaling high limit value
• Default: 0 °C
5.3 Sub setting mode
By pressing the MODE key while holding down the
▲
key, Sub setting mode can be selected.
The ▲ or ▼ key increases or decreases the setting value (numeric value).
By pressing the MODE key, setting value is registered and the next setting item is selected.
AT setting/ Auto-reset setting [ / ]
• Sets AT (Auto-tuning) or Auto-reset (offset correction).
• Auto-reset can be performed only during PD and P action.
(Not available for PID, PI and ON/OFF action)
• Default: Both Auto-tuning and Auto-reset Cancellation
[Auto-tuning]
• If the auto-tuning performance is designated, AT indicator blinks and the controller reverts to the
PV/SV display mode.
• After auto-tuning ends, AT indicator is turned off and P, I, D and ARW values are automatically
set.
• During auto-tuning, none of the settings can be performed.
• If the auto-tuning is released during the process, P, I, D and ARW values revert to their former
value.
• If the OUT /
OFF
key is pressed during auto-tuning, control output OFF function is activated, and if the
OUT /
OFF
key is pressed again, PID auto-tuning is cancelled.
[Auto-reset]
• If the auto-reset is performed, offset correction immediately starts and the controller reverts to
the PV/SV display mode. (The corrected value is automatically set and AT indicator blinks)
• During 4 minutes of auto-reset performing, other settings cannot be performed to prevent key
misoperations.
• After auto-reset ends, AT indicator is turned off and all settings can be carried out.
OUT1 proportional band setting [ ]
• Sets OUT1 proportional band.
ON/OFF action when set to 0 or 0.0.
• Setting range: 0 … 1000 °C (0 … 2000 °F)
With a decimal point: 0.0 … 999.9 °C (0.0 … 999.9 °F)
DC input: 0.0 … 100.0 %
• Default: 10 °C
OUT2 proportional band setting [
]
• Sets OUT2 proportional band.
ON/OFF action when set to 0 or 0.0.
• Not available when 2. control output (option) is not applied or when OUT1 is ON/OFF action
• Setting range: 0.0 … 10.0 times (multiplying factor to OUT1 proportional band)
• Default: 1.0 times
