ALARM (ALM) SET POINTS
Press the ALM pushbutton under the METER SETUP menu. Up to three, user selectable set points can
be used. Parameters K1, K2, & K3 in the ADVANCED PARAMETER MENU select each set point’s mode
of operation. K1 – K3 are used for pH, fluoride, or ORP set points.
The pushbutton legend has the format, “x:y,” where ‘x’ indicates a low or high set point (L or H) and ‘y’
indicates the relay number (1,2, or 3).
Examples:
L:1 is low-level set point controlling relay 1
H:2 is high-level set point controlling relay 2
ACKNOWLEDGABLE SET POINTS
These are set points in which a screen in the main residual screen is displayed that will require the
operator to decide on one of two choices: ACK or CLEAR.
ACK: The set point relay is de-energized & the buzzer (if enabled) is silenced. The set point alarm will not
appear until reset by the residual input going out of the set point’s active range.
CLEAR: The set point relay is de-energized & the buzzer (if enabled) is silenced. The set point alarm will
appear ten seconds later if the residual input does not go out of the set point’s active range.
NON-ACKNOWLEDGABLE SET POINTS
The relay will energize or de-energized based on the set point’s mode & value. No screen will be
displayed indicating the alarm and the buzzer will not sound.
PASSWORD
After one exits the CALIBRATION menu, one is first prompted to change the stored password. If
one does not want to change the password, press the NO pushbutton. If the YES pushbutton is pressed,
the SET new password screen is entered and now one can set the new password.
CALIBRATION (ALL MODES)
To calibrate from the main operating screen (flow, residual/ORP/pH, or compound loop), press the SET
pushbutton, enter the password (default is 000), and press the CAL pushbutton.
The three selections (other than escape) are as follows:
• PV3: Fluoride/ORP/pH/NH3 input.
• PV1: Residual probe calibration.
• PO1: Fluoride/ORP/pH/NH3 output.
PROBE CALIBRATION (BASIC)
Example is based on a residual probe connected to +24V SRC (+) and the +PV1 input (-).
1. Select PV1 (residual).
2. Zero a 0ppm residual by pressing the ZRO pushbutton.
3. Supply a known residual to the sensor probe and wait for a stable ppm display.
4. Press SPAN to set the known residual value in ppm units. Slew-in the correct value and press
ENT.
5. Repeat if necessary.
6. Exit to the calibrate menu by pressing the ESC pushbutton.
The residual analog input (PV1) can be “normalized” to a 4-20mA generator connected to the PV1 input.
This will not match with the residual probe calibration.
