Metex MX-320 is a microprocessor based dual channel timer/controller
that can operate a solenoid blowdown valve and chemical feed
pump in proportion to any standard contact head water meter.
Each timer has an independent accumulator (counter) for setting
the make-up water meter trip point.
Special warning feature advises incorrect settings.
The Metex MX-320 is used in boiler control applications.
For cooling tower applications use the Model MX-310.
The Metex MX-300 can be configured for two different modes
The chemical pump and blowdown valve operate independently from
a signal from the water meter.
The valve relay is triggered first by the water meter, and after
having timed out, the pump relay is triggered. The pump and
valve timers will never be on simultaneously.
In the Test Mode, either output relay can be manually activated
for its pre-set time.
In the Prime Mode, either output relay will run for 5 minutes,
then revert to automatic control.
