Description of Unit
MegaTronXS controllers control a single recirculating water system including closed loop applications and
may have various features depending on the model number.
Standard Timer
The standard timer is designed to automate a mixer action activating a relay output. This timer can be
programmed to be one of the following types.
*1.
Pulse Time
- Accepts pulses from a make-up water meter (supplied separately). It can accumulate
1-9999 gallons before activating the timer to run.
*2.
Feed with Bleed
- Activates the relay output simultaneously with the bleed and limits the amount
of time the relay output will be on during the bleed cycle.
*3.
Feed after Bleed
- Activates the relay output based on a user defined percentage of time based
on the bleed off, another timer or digital input. The relay is activated after a bleed cycle and runs
for the set percentage of that bleed cycle.
4.
Recycle
- The relay is continuously repeating a defined OFF cycle time and a user defined ON
cycle time.
5.
28 Day
- The timer is based on a 28 day cycle with four independent programmable feed cycles
with prebleed and bleed lockout settings.
* Note: These functions are for application other than glycol feeders.
