4. Starting up
When you initially connect power to the controller, it will automatically enter
Measurement mode. This controller features a large dual display.
• The upper display will show the present conductivity (resistivity) value
• The lower display will show the temperature value
Annunciators along the right side of the display will indicate whether the controller is
set for conductivity or resistivity measurement.
Security codes
To access calibration and set up functions, you need to enter a security code.
This controller features two levels of security codes to protect the numerical values,
calibration data and unit parameters from unintentional alteration.
The two security codes are as follows:
—conductivity (resistivity) calibration mode security code = 11.
— Setup mode security code = 22.
You cannot change calibration and set up parameters unless you first enter
the security code.
You can, however, view all parameters without knowing the
security code.
• Refer to Section 5 on page 18 for more information on the Calibration mode
• Refer to Section 6 on page 23 for more information on the Advanced Set-up mode.
Security code notes
If you are viewing the parameters only, the controller automatically reverts to
Measurement mode if you do not press a button for 1 minute. If you are changing
parameters, the controller automatically reverts to Measurement mode if you do not
press a button for 15 minutes.
Viewing operating parameters
You can view operating parameters without entering the security code.
However, you must enter the security code to change parameters.

Viewing relay set point values:
1.
Press the Relay Selection (Rel A/Rel B) key.
The upper display will show your
set-point value for Relay A; the lower display will show “SP1”.
2.
After two seconds the upper display will show your set-point value for Relay B;
the lower display will show “SP2”.
3.
After an additional two seconds the controller will return to Measurement mode.
Viewing electrode status:
1.
Press the CAL key.
The display will cue you to enter a security code (C.Cd).
2.
Leave the security code at “000”
.
3.
Press the ENTER key.
The upper display shows the electrode status. The lower
display will show “CEL”.
4.
Press the ENTER key again
to return to measurement mode.
Viewing set up parameters:
1.
Press the ENTER key.
The display will cue you to enter a security code (S.Cd).
2.
Leave the security code at “000”
.
3.
Press the ENTER key again.
This lets you view (not change) sub groups.
4.
Press the
▲
and
▼
keys
to scroll through the groups.
5.
Press the ENTER key
to view a sub group you wish to see in more detail.
6.
Press the ENTER key repeatedly
to scroll through the parameters of the sub
group you selected.
7.
Press the
▲
and
▼
keys
when you return to the sub group head to select
another subgroup.
8.
Repeat steps 4 to 7 as needed.
9.
