Microprocessor Based
Conductivity pH Controllers Model 2430P

Model 2430P Microprocessor-Based Conductivity and ORP Controllers

LONWORKS^* Technology is the latest in microprocessor capability that gives the user the highest level of application flexibility.

A large illuminated graphics screen, multiple inputs and very easy setup with easy field upgrade characterize this new technology.

The unit does not include plumbing or a sensor. For use with process-type conductivity sensors (order separately).

• 4-electrode conductivity input includes fouling compensation and alarm.
• Differential ORP sensor input with diagnostics indicate fouled reference or open PT band.
• Input for flowswitch lockout.
• Two water meter inputs, MTR1 and MTR2.
• Conductivity Blowdown Relay options:

• Bleed x gallons for every x gallons makeup
• Bleed x minutes for every x gallons of makeup
• Bleed by setpoint
• Bleed by cycles of concentration with NCON/NCKT Option
• Bleed by multi-setpoint selected with NCON/NCKT Option

Three user-selectable relay options (four additional with NRLY):

• Feed by setpoint, direct or reverse;
• Water meter actuated feed. MTR1, MTR2 or sum;
• Feed after blowdown by percent of bleed time;
• Feed by percentage of time;
• Feed by schedule (-RTC Option);
• General alarm contact.

• Three security levels:

• View only
• Operator
• Technician

Four different languages.

• English Spanish (standard)
• English French (optional)
• English German(optional)
