Mode:
Select ‘AUTO’ (Automatic) or ‘MANL’ (Manual)
Automatic enables the temperature to be automatically detected via the thermistor.
Manual Temp:
This will show ‘OFF’ unless the mode is ‘MANL’, in which case the value is adjustable.
Sample Calibration:
This line is visible when the temperature mode is set to ‘AUTO’. The temperature
displayed represents what the program interprets the current temperature reading to be. If necessary,
adjust the displayed temperature using the
and
buttons.
Alarm and Relay Setup:
This screen allows the user to change the following values and parameters for the
four alarm relays (Relay 1, Relay 2, Relay 3, Relay 4):
Alm Mode
(Alarm Mode): Select ‘Latching’ or ‘Non-latching’
A latching relay will require manual acknowledgement of any alarm condition (by pressing the [MINUS]
button with the Main Screen active). When Non-Latching is selected, alarms will clear themselves
whenever the alarm condition no longer exists.
Alm Delay
(Alarm Delay): Adjust the delay time. Any alarm condition must then exist for this period of
time before tripping the relay. This delay can help avoid false alarms and is recommended to be set at 5
seconds or longer.
Relay 1, 2, 3 or 4:
The monitor is equipped with four alarm relays. Each of these relays can be
individually set to represent any of the following alarm conditions:
pH High/Low Alm
(pH High or Low Alarm)
ORP High/Low Alm
(ORP High or Low Alarm)
Cond High/Low Alm
(Conductivity High or Low Alarm)
PV1 Low
(PID control water
fl
ow low alarm.)
Any Alm
(Any of the listed alarm conditions.)
4/20mA Outputs Setup:
This screen accesses the settings for the four 4-20mA output channels.
AO1, AO2, AO3 or AO4:
Each analog output channel can be individually set to represent one of the
following live readings (with corresponding values shown for 4mA and 20mA outputs):
4mA
20mA

[HIDDEN] 4/20mA Calibration:
This hidden screen can be accessed by holding the
button when the
AO3 line is selected (on the 4/20mA Outputs Setup screen). While using an ammeter to measure the output
current, the following calibration values can be adjusted using the
and
buttons:
NOTE: Adjustable values on this screen are Digital-to-Analog Converter (DAC) values.
AO1 4mA Cal:
Adjust the DAC value that corresponds to 4mA for Analog Output 1 (AO1)
20mA Cal:
Adjust the DAC value that corresponds to 20mA for Analog Output 1 (AO1)
AO2 4mA Cal:
Adjust the DAC value that corresponds to 4mA for Analog Output 2 (AO2)
20mA Cal:
Adjust the DAC value that corresponds to 20mA for Analog Output 2 (AO2)
AO3 4mA Cal:
Adjust the DAC value that corresponds to 4mA for Analog Output 3 (AO3)
20mA Cal:
Adjust the DAC value that corresponds to 20mA for Analog Output 3 (AO3)
AO4 4mA Cal:
Adjust the DAC value that corresponds to 4mA for Analog Output 4 (AO4)
20mA Cal:
Adjust the DAC value that corresponds to 20mA for Analog Output 4 (AO4)
