NELSEN CHIP RO Controller System Controller Documentation Instruction Manual

Table 1 – Specifications

Inputs

Tank level switch| (1) Normally-Closed. RO Runs on switch closure.
Inlet pressure switch| Normally-Open. Switch opens on low pressure.
Pretreat lockout switch| Normally-Open. Pretreat lockout active with switch closure
NOTE : All switch inputs are dry contacts. Voltage applied to the switch inputs will damage the controller
Controller Power| 120/240 VAC, 60/50Hz (Range: 96-264 VAC)
The switching power supply automatically adjusts to supply voltage. Voltage applied to the input is the same voltage the motor and valves will operate on.
Output Relay Ratings
Feed Solenoid| 12A. Output Voltage is the same as motor/supply voltage.
Flush Solenoid| 12A. Output Voltage is the same as motor/supply voltage.
The solenoid relay ratings above reflect the capacity of the relays only. The current capacity of each circuit is 2A.
Motor| 1.0 HP @ 120V
2.0 HP @ 240V
Circuit Protection
Controller Power Fuse| F1 5x20mm| 1/4 (0.25) Amp| Little Fuse 0218.250MXP
Branch circuit protection, motor and valve protection must be provided externally
Other
Dimensions| 7” tall, 5” wide, 2.375” deep. Nema 4X Polycarbonate Enclosure
Weight| 1.1 lb.
Environment| 0-50°C, 10-90%RH (non-condensing)

Table 2 – Controller Programming: CHIP Program Selections

The controller has 4 separate user-selectable sets of settings for configuring the RO. The factory default 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 select these programs.
See Appendix A for a detailed explanation of the Parameters and their affect on the RO’s operation.
See Appendix B for information on the programming interface for use in modifying these settings.

Parameter| Value| Program 1| Program 2| Program 3| Program 4

Tank Level Switch delay (actuation and de-actuation)| Seconds| 2| 2| 2| 2
Pressure Switch delay (actuation and de-actuation)| Seconds| 2| 2| 2| 2
Pretreat Switch delay (actuation and de-actuation)| Seconds| 2| 2| 2| 2
Pump start delay| Seconds| 10| 10| 10| 10
Inlet Solenid stop delay| Seconds| 1| 1| 1| 1
Pump start retry interval (restart delay after LP fault)| Seconds| 60| 60| 60| 60
Low pressure fault shutdown, # of faults| Faults| 5| 5| 5| 5
Low pressure fault shutdown, time period to count faults| Minutes| 10| 10| 10| 10
Low pressure fault shutdown, reset after shutdown| Minutes| 60| 60| 60| 60
Low pressure time out fault| Seconds| 60| 60| 60| 60
Flush Behavior| –| High Pressure| No Flush| Perm Flush| Low Pres Flush
Startup Flush: Minutes from last flush| Minutes| 0| 0| 0| 0
Startup Flush: Duration| Seconds| 0| 0| 0| 30
Periodic Flush: Interval| Minutes| 60| 0| 0| 0
Periodic Flush: Duration| Seconds| 30| 0| 0| 0
Shutdown Flush: Time from last flush| Minutes| 10| 0| 0| 0
Shutdown Flush: Minumum operation| Minutes| 30| 0| 0| 0
Shutdown Flush: Duration| Seconds| 60| 0| 60| 60
Idle Flush: Interval | Minutes| 0| 0| 0| 0
Idle Flush: Duration | Seconds| 0| 0| 0| 0

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.
