9 P1-A TDS Probe 1 PPM Alarm Setpoint
This item is used to set the TDS alarm setpoint for conductivity probe number 1. The setpoint may be
adjusted anywhere between 10 and 9990 PPM in 10 PPM increments. A setting of 0 will disable this
alarm. When the TDS value goes beyond the alarm setpoint, an alarm flag will be set to start processing
the alarm relay time delay. Once this time delay is complete, the relay will energize indicating an alarm.
10 P2-A TDS Probe 2 PPM Alarm Setpoint
This item is used to set the TDS alarm setpoint for conductivity probe number 2. The setpoint may be
adjusted anywhere between 10 and 9990 PPM in 10 PPM increments. A setting of 0 will disable this
alarm. When the TDS value goes beyond the alarm setpoint, an alarm flag will be set to start processing
the alarm relay time delay. Once this time delay is complete, the relay will energize indicating an alarm.

A TDS Probe 1 Temperature Alarm Setpoint
This item is used to set a temperature alarm setpoint for conductivity probe number 1. The setpoint may
be adjusted anywhere between 33
°
F and 167
°
F in 1
°
F increments. A setting of 32
°
F will disable this
alarm. When the temperature of this probe goes above the alarm setpoint, an alarm flag will be set to
start processing the alarm relay time delay. Once this time delay is complete, the relay will energize
indicating an alarm.

A TDS Probe 2 Temperature Alarm Setpoint
Although the TDS Probe 2 Temperature is not available on the front panel display, you can still setup an
alarm level and the unit will correctly respond to this alarm. An alarm condition will be displayed,
however the source of this alarm will not be displayed. This item is used to set a temperature alarm
setpoint for conductivity probe number 2. The setpoint may be adjusted any where between 33
°
F and
167
°
F in 1
°
F increments. A setting of 32
°
F will disable this alarm. When the temperature of this probe
goes above the alarm setpoint, an alarm flag will be set to start processing the alarm relay time delay.
Once this time delay is complete, the relay will energize indicating an alarm.
13 Pr-A Percent Rejection Alarm Setpoint
This item is used to set a percent rejection alarm setpoint when two conductivity probes are used. Probe
1 should be used as the product probe or the probe having a lessor value. Probe should be used as the
Feed water probe or probe having a greater value. The setpoint may be adjusted anywhere between 1%
and 99% in 1% increments. A setting of 0% will disable this alarm. When the percent rejection falls
below alarm setpoint, an alarm flag will be set to start processing the alarm relay time delay. Once this
time delay is complete, the relay will energize indicating an alarm.
14 C--F Select Degree C or F for Display
This item is used to select whether the TDS monitor display temperature in degree C or degree F.
Setting a 1 in this menu will select degree F and a 0 will select degree C.
