7.6 CHANGING OUTPUT PARAMETERS (continued)
main sensor (total chlorine). Press Save (F4) to store the selec-
tion.
e. The display returns to the “Output: Process” screen. Press Exit
(F1). The display returns to the “Output Measurement” screen.
Move the cursor to "Control mode" and press Enter (F4).
f. Press Edit (F4). Use the key to toggle between "Normal" and
"PID". Press Save (F4) to store the selection.
8. Output setup for normal outputs:
a. Move the cursor to the desired output setup and press Enter (F4).
b. Use the and arrow keys to move the cursor to the desired
parameter. Press Edit (F4). Use the arrow keys to change the set-
ting to the desired value and press Save(F4) to store the value.
Range: Choose 4-20 mA or 0-20 mA.
Dampen: Dampening averages the output current, thus smooth-
ing out a noisy reading. Higher values provide more smoothing
but increase the response time of the output.
Hold and Fixed Hold: If the analyzer is placed in hold, the out-
puts will either remain at the last value or go to a fixed value
selected by the user. The fixed value must be between 0 and
22.00 mA.
Fault: If the analyzer detects a fault, the output will signal the fault
by going to a user-selected current between 0 and 22.00 mA.
For allowed values, see Table 7-1.
9. Output setup for PID outputs:
a. Move the cursor to the desired output setup and press Enter (F4).
b. Use the and keys to move the cursor to the desired param-
eter. Press Edit (F4). Use the arrow keys to change the setting to
the desired value and press Save (F4) to store the value.
Setpoint: Setpoint is usually the value at which the process is
being controlled. Typically, the output will be 4 mA (or 0 mA) when
the value is near the setpoint.
