The electronic level controller with 2 sensors will automate aquarium water top off. Since safety is our number one concern, we include two float switch sensors with our electronic water level controller. The first float switch sensor triggers the feed pump (sold separately) to maintain the desire water level. The second float switch sensor ensures dependability and offers overflow protection. Our water level controller can also be used to protect pump from running dry. It can be utilized in three ways :
1.In this mode the power supply will turn on if the water level in the sump is low AND there is enough water in the storage tank. The power supply will turn off if the water level in the sump is high AND there is not enough water in the storage tank.
(View Operation diagram, MODE A-1)
With this set up the power supply will turn on as soon as the water level in the sump drops below the set level. The power supply will turn off if the water level in the sump is high the set level.
(View Operation diagram, MODE A-2)
2. The power supply will turn on when the level falls below the minimal level of float sensor1 and will turn off when water rises the set point of the flow sensor1. The float sensor2 acts as a backup sensor in the event the float sensor1 is stuck. The level controller will not allow the power supply to turn on if the water level in the sump reaches the maximum level of float sensor2.
(view Operation diagram, MODE B)
3. Immerse the sensor1 and sensor2 in the measured solution (sump).With this set up the power supply will turn on when both sensors detected that the water level is below the minimum level and stop only when the water rises the maximum level of both sensor.

ROC-2015 RO Controller Main functions

Dry-run protection function

 

It is used to monitor water source when raw water is cut off (low level of water storage tank and the pressure of pipeline getting too low) to prevent from system idling. The controller stops the operation of whole RO system, while the indicator light on panel for ※LOW FEED PRESS§ lightens and buzzer sounds. After that, the controller will detect dry-run switch uninterruptedly, and if the water supply pressure or water level returns to normal, the controller will restart RO system for operation.

Low-pressure protection function

When front-end pretreatment system is in flushing or regenerating state, the security filter being dirtied and jammed, and cannot supply normal feeding pressure for RO system (namely the low pressure is insufficient) , the controller will temporally shut down the whole RO system. At this moment, the indicator light for ※LOW PRESS§ and the buzzer sounds.

Then, the controller will continuously detect the low-pressure protection switch, and after the pressure recovery for 1 minute, RO control system will start at first time, and operate RO system.

In event of low-pressure protection for system again, stop the operation of RO system. The procedure sets three times of trial running, and when they are not successful, the system will enter deadlock protection state. The indicator light for low-pressure protection is on to reminder the reason to shut down, and is waiting for restart by pressing the reset key after treatment by manpower.

High-pressure protection function

In some systems with high-pressure protection, if the system has overpressure, the controller will automatically close the whole RO system, and the indicator light for "HIGH PRESS" lights up. After elimination of high pressure for 1 minute, the controller will perform trial running at the first time. If the outlet pressure still has overpressure, the system will become into protection state again. The high-pressure protection procedure sets three times of trial running, and when they are not successful, the system will go into deadlock protection state and the buzzer sounds.

  *If the system has no high-pressure protection, short out the terminal (COM+HP)

Pure water tank level Control function 

When pure water tank level is at preset low level, the controller will start RO system immediately to generate water till the level of pure water tank up to the preset high level, and the system will flush membrane completely and shift to standby state.

Membrane flushing function

  When the protective device and state is normal, the system will perform membrane flushing every time power up, and then repeat it every low-level water preparing. When the water producing tank is filled, the membrane flushing will be automatically ended.
