iControls ROC-2HE-UL Reverse Osmosis System Controller

INSTRUCTIONS

Welcome.
Thank you for purchasing an iControls controller.

You made a good choice in choosing iControls. You can expect years of trouble- free service. With a design based on feedback from leaders in the RO field plus our own experience in RO system design and manufacture, iControls RO controllers are truly best in class.

As good as our controllers are, there’s always room for improvement. If you have an experience, idea or input either positive or negative we’d love to hear from you. Again, thanks for your purchase. Welcome to the community of iControls users.

Inputs

• Tank level switches: (2) Normally-Closed. Can be used with a single level switch.

• Inlet pressure switch: Normally-Open.

• Pretreat lockout switch: Normally-Open
  The Tank, Low Pressure and Pretreat inputs are 50% duty cycle square wave, 10VDC peak @ 10mA max. The switch inputs are dry contacts only. Applying voltage to these terminals will damage the controller.

• Controller Power: 110-120/208-240 VAC, 60/50Hz (Range: 110-240 VAC)

• Permeate Conductivity: 0-3000 PPM, 0-6000 µs (standard sensor, CP-1, K=.75)

• Feed Conductivity (opt): 0-3000 PPM, 0-6000 µs (standard sensor, CP-1, K=.75)

Output Circuit Ratings

• Feed Solenoid: 1A. Voltage is the same as motor/supply voltage.
• Solenoid Flush: 1A. Voltage is the same as motor/supply voltage.
• Motor: 1.0 HP/110-120V, 2.0 HP/208-240V.

Circuit Protection
Relay Fuse: F1 5x20mm 2 Amp  BelFuse 5ST 2-R
Note: The fuse shown above are for supplemental protection only. Branch circuit protection and disconnect means must be provided externally.
See Field Wiring Diagram for Branch Circuit protection requirements.

Other
Dimensions: 7” tall, 7” wide, 4”” deep. Nema 4X Polycarbonate Hinged Enclosure.
Weight: 2.6 lb. (Basic Configuration, not including optional wire harness,
Environment: etc..) 0-50°C, 10-90%RH (non-condensing)

Controller Programming: Menu Navigation

This is a partial view of the internal menus. Additional editable items include: Language, Audible Alarm (ON/OFF), WQ Loss of Signal setting, Hardware & Firmware Version and more.

Controller Programming: ROC-2HE Program Selections

The controller has 4 separate user-selectable sets of settings for configuring the RO. The factory de-fault settings are shown below. The settings are identical except for variations in the flush behavior.

• Program 1, High Pressure flush.
• Program 2, No Flush
• Program 3, Permeate Flush, (low pressure, inlet valve closed)
• Program 4, Low Pressure, feed water flush
• See the previous page for instructions on how to access the menu for selecting these programs.
• See Appendix A for a detailed explanation of the Parameters and their affect on the RO’s operation.

These features are disabled by default due to the potential for confusion on the part of end-users in the field. They can be enabled when needed via the OEM PC programming interface which allows changes to all of the values shown above.

Controller Fault Condition Displays

Below are examples and explanations of the displays which accompany the fault conditions possible on the CPU-4. Fault conditions always indicate a problem of some sort which requires corrective action. the displays provide sufficient information to recognize the source of the fault and the required correc-tive action.

Low Pressure Fault: (System is responding to low pressure condition per system settings)

• Line 1 “Service Fault”
• Line 2 “Low Feed Pressure”
• Line 3
• Line 4 “Restart in MM:SS”

Pre Treat Fault: (Pretreat Switch is closed indicating problem with pretreat system).

• Line 1 “Service Fault”
• Line 2 “Pretreat”
• Line 3
• Line 4 “Check Pretreat Sys.”

Permeate Conductity Fault: (Permeate conductivity is higher than the alarm setpoint.)

• Line 1 “Service Fault”
• Line 2 “Permeate TDS xxx ppm” or “Permeate Cond xxx uS”
• Line 3 “Alarm SP xxx ppm” or “Alarm SP xxx uS”
• Line 4 “To Reset Push OFF/ON”

Feed Conductivity Fault: (Feed conductivity is higher than the alarm setpoint.)

• Line 1 “Service Fault”
• Line 2 “Feed TDS xxx ppm” or “Feed Cond xxx uS”
• Line 3 “Alarm SP xxx ppm” or “Alarm SP xxx uS”
• Line 4 “To Reset Push OFF/ON”

Conductivity Probe Error messages:

• Line 2 “Inteference” – Noise detected by conductivity circuit, valid measurement not possible.
• Line 2 “Over-range” – Measurement is out of range for the circuit, probe may also be shorted
• Line 2 “Probe shorted” – Short circuit detected on temperature sensor in probe
• Line 2 “Probe not detected” – Open circuit detected on temperature sensor in probe (white and un-shielded wire)
• Line 2 “Probe Startup 1” – Internal reference voltage too high to make valid measurement
• Line 2 “Probe Startup 2” – Internal reference voltage too low to make valid measurement
• Line 2 “Probe Startup 3” – Internal excitation voltage too high to make valid measurement
• Line 2 “Probe Startup 4” – Internal excitation voltage too low to make valid measurement

Appendix B. Controller Programming: Programming Interface Overview

The Programming interface is a Windows-based tool for making changes to the ROC software. This screen shows the RO settings available. There are 4 field- selectable sets of settings stored in the CPU-.4

Appendix C. Warranty

iControls Limited Warranty

What the warranty covers:
iControls warrants the ROC 2HE to be free from defects in materials and workmanship during the war-ranty period. If a product proves to be defective during the warranty period, iControls will at is sole option repair or replace the product with a like product.
