CRYSTAL QUEST C-150 Commercial and Industrial Reverse Osmosis System
Control Panel Installation Guide
CQ150 INTRODUCTION
The Advantage C-150 controller is a state of the art control system for commercial and industrial reverse osmosis systems. The C-150 is a microprocessor-controlled system that can monitor pressure and level switches. A TDS/ Conductivity monitor/controller with programmable Setpoints is an integral part of the C-150. The C-150 displays system status and sensor and switch input status on an easy to read backlit display. User programmable Setpoints are provided that allow fast and easy adjustment of system parameters.
INSTALLATION
-
Mounting Instructions
Mount the C-150 in a convenient location on the RO equipment using the four mounting ears provided with the unit or the optional panel mounting bracket.
Note: All terminals on the board are labeled. -
Terminal Strip, Jumper and Adjustment Locations
Refer to Figure 1 on page 6 for the location of all terminal strips and connectors. Figure 1 also shows all jumper and adjustment locations. Figure 2 on page 7 shows a sample wiring diagram. -
Power Wiring
Refer to Figures 1-2 for terminal strip locations. AC power for the unit is connected to terminal strip P1. Connect the ground wire of the AC power to the terminal labeled GND. For AC power with a neutral and hot wire, the hot wire connects to L1 and the neutral wire connects to L2. For AC power with 2 hot wires, either wire can connect to L1 and L2. On AC power with 2 hot wires, the wire jumper between P6 and P7 should be removed and a fuse (GMA 1/4A) installed in F2. -
Pump and Valve Relay Outputs
The C-150 supplies relay outputs to control the RO pump and solenoid valves.
Note: The relays output the same voltage as the AC power to the board. If the pump and solenoids operate on different voltages, a contactor will need to be supplied to operate the pump. -
Reverse Osmosis Pump Wiring
The RO pump connects to the L1 and L2 RO pump terminals of P1. This output can operate 120/240 VAC motors up to 1HP directly. For motors larger than 1HP or 3 phase motors, this output can be used to operate a contactor. -
Inlet and Flush Valve Wiring
The inlet and flush valves must operate at the same voltage as supplied to the board. These outputs can supply 5A maximum and are not designed to operate pump motors directly. If these outputs are to be used to operate a boost or flush pump, the output should be used to operate a contactor. The inlet valve connects to the L1 and L2 inlet terminals of P1. The flush valve connects to the L1 and L2 flush terminals of P1. -
TDS / Conductivity Cell Wiring
For accurate TDS/Conductivity readings, the cell should be installed in a tee fitting where a continuous flow of water passes over the cell and no air can be trapped around the cell. Refer to Figure 2 on page 7 for example installation. The cell is connected with 5 wires to terminal strip P10. Connect each colored wire to the terminal labeled with the same color.
TDS CONDUCTIVITY SENSOR AND EXPANDER
Screw the sensors into the end of a pipe tee with the fluid flow in the
direction indicated. Position the sensor in a place that will prevent air
being trapped in the area of the sensor. The TDS/Conductivity expander board
allows a second TDS/conductivity to be monitored and displayed by the C-150
controller. The expander board is mounted on the main board to the left of the
connector for the 1st cell. The figure (above right) shows the wiring and
adjustment information for the expander.
SWITCH INPUTS
The connections for these inputs are not polarity sensitive and can be connected to either terminal. The switch inputs should be dry contact closures only.
NOTE: Applying voltage to these terminals will damage the controller. The switches can be either normally open or normally closed in any combination. The switch connected to an input that is configured as normally open must be open for the unit to run. The switch connected to an input that is configured as normally closed must be closed for the unit to run. The Switch Select Setpoint allows each input to be configured as normally open or normally closed. The Switch Select Setpoint is defaulted to 31 which programs all inputs as normally closed. This means that all switch inputs must be closed for the unit to run. The table lists the values used to program the Setpoint to configure the inputs.
PRESSURE FAULT SWITCH
On systems where a low feed pressure shut down is required, a feed pressure
switch can be connected to the pressure fault input of P9. If a high pump
pressure shut down is required, a high pressure switch can be connected to
this input. If both low feed pressure and high pump pressure shut down are
required, both switches can be connected to this input.
Both switches must be either normally open or normally closed to operate
properly.
PRETREAT SWITCH
In systems with pretreatment, a pretreat lockout switch can be connected to
the pretreat input of P9. This switch should operate when the pretreatment
device is out of service.
Note: The output from the pretreatment device must be a dry contact and
must not supply voltage.
TANK FULL SWITCH
In systems with a single tank level switch for controlling the RO pump, the
level switch connects to the tank full high input of P9. If dual level
switches are used for controlling the RO pump, the upper level switch connects
to the tank full high input of P9 and the lower level switch connects to the
tank full low input of P9.
SWITCH | N.O. | N.C. | VALUE |
---|---|---|---|
PRESSURE FAULT | 0 | 1 | |
PRETREAT | 0 | 2 | |
TANK FULL HIGH | 0 | 4 | |
TANK FULL LOW | 0 | 8 | |
CHEM TANK LOW | 0 | 16 | |
TOTAL |
Select the type of switch used for each input and put that number in the value column. Add the values and program the total in the Switch Select Setpoint. For example, if the pressure fault and tank low inputs were normally closed and all others normally open, the value programmed in the Switch Select Setpoint would be 17(1 + 16).
I/O EXPANDER BOARD
If the optional I/O expander board is installed, 2 additional relay outputs
and 1 additional switch input are provided. AC power for the relays is
connected to the L1 and L2 power terminals of P1. Relay 1 is connected to this
power input and will supply the same voltage.
This relay is rated for 120/240VAC at 1HP maximum. Relay 1 can be configured
to supply a dry contact by connecting a jumper wire between the L1 and L2
power terminals of P1.
NOTE: If Relay 1 is configured as a dry contact, Relay 2 must be configured as a dry contact also. If Relay 1 is configured to supply voltage, Relay 2 can be selected to supply voltage, 120/240, 5A maximum, or as a dry contact output. Jumpers J1-J4 are used to select the relay 2 output type. To output voltage, a wire jumper is installed between J1 and J4 and a second wire jumper is installed between J2 and J3. For a contact closure output, a single wire jumper is installed between J3 and J4. The 2 relay outputs are programmed to operate as a divert output and an alarm output.
EXPANDER MODE | RELAY 1 | RELAY 2 |
---|---|---|
0 | AUXILIARY PUMP | DIVERT |
1 | AUXILIARY PUMP | ALARM |
2 | DIVERT | ALARM |
3 | BOOST | DIVERT |
4 | BOOST | ALARM |
AUXILIARY PUMP
If the Expander Mode Setpoint is programmed to 0 or 1, relay 1 operates as an
auxiliary pump output. This output is energized when the tank low input is not
active. This output will supply power or a contact closure determined by the
connections L1 and L2 of the terminal strip P1.
BOOST PUMP
If the Expander Mode Setpoint is programmed to 3 or 4, relay 1 operates as a
boost pump output. This output is energized when the inlet solenoid output is
active. This output will supply power or a contact closure determined by the
connections L1 and L2 of the terminal strip P1.
DIVERT OUTPUT
If the Expander Mode Setpoint is programmed to 0 or 3, relay 2 operates as a
divert relay and will operate whenever the unit is in the divert mode. This
output will supply voltage or provide a contact closure based on the
configuration of relay 1 and on the position of jumpers J1-J4. If the Expander
Mode Setpoint is programmed to 2, relay 1 operates as a divert relay and will
operate whenever the unit is not in the divert mode. This output will supply
power or a contact closure determined by the connections L1 and L2 of the
terminal strip P1.
ALARM OUTPUT
If the Expander Mode Setpoint is programmed to 1, 2 or 4, relay 2 operates as
an alarm relay. When an alarm or warning is active, this relay will supply
voltage or provide a contact closure based on the configuration of relay 1 and
the position of jumpers J1-J4.
CHEMICAL TANK LOW SWITCH
A chemical tank low switch input can be connected to the tank low input of P2
on the expander board. This input will provide a chemical tank low alarm and
will cause the unit to shut down.
TERMINAL STRIPS, JUMPERS AND WIRING DIAGRAM
CAUTION
1.| There are live circuits inside the controller even when the power switch
on the front panel is in the OFF position. Never open the front panel without
first disconnecting power from the outlet. Prewired controllers are supplied
with an 8 foot, 18 AWG power cord with USA style plug. A #1 Phillips driver is
required to open the front panel.
2.| Low voltage signal wires (probes, flow switch, water meter, etc.) should
never be run in conduit with high voltage (like 115VAC) wires.
3.| Never attempt to land connections to the controller without first
disconnecting power from the outlet.
4.| Do not block access to disconnect power during mounting and installation.

TANK FULL OPERATION
The unit can be operated with 1 or 2 level switches. With 1 level switch, the
switch is connected to the tank full high input. When this switch has been
active for 5 seconds, the unit will shut down on tank full. TANK FULL will
show on the display. When the tank full condition clears, the unit will
restart when the tank full restart delay times out.
For 2 level switch operation, the upper switch is connected to the tank full
high input and the lower switch is connected to the tank full low input. When
both switches are clear, the RO unit will run. The RO unit will continue to
run when the water level rises and the lower switch becomes active. When the
upper switch becomes active, after the 5 second delay, the RO unit will shut
down. TANK FULL will show on the display.
When the tank level drops and the upper level switch clears, the RO unit will
remain off. When the lower level switch clears, the RO will restart when the
tank full restart delay times out.
TANK FULL RESTART
The tank full restart is the delay before the RO unit starts when a tank full
condition clears. This delay can be in minutes or in seconds. The TF Restart
Setpoint selects seconds or minutes.
TANK FULL OVERRIDE
A timed tank full override can be initiated when the RO unit is shut down due
to a tank full condition. Pressing the Alarm Silence/Reset key for 3 seconds
during a tank full condition will enable the tank full override. The RO will
start and OVERRIDE 9 will show on the display. The number is the minutes
remaining in the override timer. When the override times out, the unit will
return to the tank full shut down condition.
PRESSURE FAULT
If the pressure fault input becomes active and stays active for the delay
programmed in the PF Delay Setpoint, the unit will shut down for a pressure
fault. The display will show PSI FAULT, the alarm lamp will flash and the
audible alarm will sound. The pressure fault can be cleared by pressing the
Alarm Silence/Reset key twice.
CHEMICAL TANK LOW
When the chemical tank low input has been active for the time programmed in
the Chem Low Delay setpoint, an alarm will be generated and the unit will shut
down. The display will show CHEM LOW, the alarm lamp will flash and the
audible alarm will sound. The fault can be cleared by pressing the Alarm
Silence/Reset key twice.
AUTO RESET/RETRIES
If a pressure fault shut down occurs and the Auto Reset Setpoint is programmed
to 0, the unit will remain shut down until manually reset. If the Auto Reset
Setpoint is programmed to a value greater than 0, the unit will automatically
clear the pressure fault and attempt to restart after this delay times out.
If the Retries Setpoint is programmed to a value other than 0, after the Auto
Reset times out, the retry count will be incremented and the system will
attempt to restart. If the pressure fault is still active, the system will
again shut down. The system will attempt to restart for the number of times
programmed in the Retries Setpoint and will then remain shut down until
manually reset. If the system starts and is able to run continuously for 60
seconds, the retry count will be reset to 0.
HIGH TDS / CONDUCTIVITY WARNING/ALARM
If the permeate TDS / Conductivity reading exceeds the limit programmed the C2
Limit Setpoint for the delay programmed in the C2 Delay Setpoint, the alarm
lamp will light and the HI Cond 2 warning message will show on the display.
This warning will clear when the TDS/ Conductivity drops below the Setpoint.
If the Shutdown Delay Setpoint is programmed to 0, the unit will continue to
operate. Otherwise, once a high TDS/Cond warning occurs, after the time
programmed in this setpoint, the RO unit will shut down and the alarm will
sound. The alarm can be cleared by pressing the Alarm Silence/Reset key twice.
NOTE: the auto reset function is not active for this shut down.
HIGH TEMPERATURE
If the feed water temperature exceeds the value programmed into the High Temp
setpoint for 5 seconds, the unit will shut down for a high temperature alarm.
The display will show HIGH TEMP, the alarm lamp will flash and the audible
alarm will sound. The fault can be cleared by pressing the Alarm Silence/Reset
key twice.
ALARM SILENCE
When a shut down occurs that causes the audible alarm to sound, the alarm can
be silenced by pressing the Alarm Silence/Reset key once. The alarm will
remain silenced if the Alarm Silence Setpoint is programmed to 0. If the Alarm
Silence Setpoint is programmed to a value greater than 0, the alarm will
resound after this delay times out.
Pressing the Alarm Silence/Reset key will silence the alarm and reset this
delay.
PRETREAT
If the pretreat input becomes active and stays active for 2 seconds, the unit
will shut down in a pretreat lockout condition. PRETREAT will show on the
display and the unit will remain shut down as long as the pretreat input is
active.
DIRECT FEED
If the Direct Feed setpoint is programmed to 0, the unit will operate normally
with the tank full inputs controlling the operation of the unit. If the Direct
Feed setpoint is programmed to 1, the unit will ignore the tank full inputs.
The unit operation is controlled with the power key.
FLUSH
When the unit starts, the controller will begin a start up flush. During this
flush, the inlet, flush and divert valves will be open and the RO pump will be
off. The flush will last for the number of seconds programmed in the Flush
Time 1 setpoint. When the flush times out, the controller will go through the
start sequence. When the unit stops, the controller will begin a stop flush.
During this flush, the inlet, flush and divert valves will be open and the RO
pump will be off. The flush will last for the number of seconds programmed in
the Flush Time 1 setpoint. When the flush times out, all outputs will turn
off. When the unit has been shut down continuously for the time programmed in
the Flush Interval setpoint, the unit will begin an off hours flush. During
this flush, the inlet and divert valves will be open and the RO pump will be
on. The flush will last for the number of minutes programmed in the Flush Time
2 setpoint. When the flush times out, the unit will shut down.
HI OPERATING HOURS
If the current hours exceed the limit programmed in the Maximum Hours
Setpoint, the alarm lamp will light and the HI HOURS warning message will be
shown. This warning can be cleared by programming the current hours to 0 or by
increasing the maximum hours limit.
DIVERT OUTPUT
When relay 1 or relay 2 has been programmed to operate as a divert relay, the
relay will de-energize when the TDS/Conductivity exceeds the TDS/Cond Limit
Setpoint. This will occur as soon as the reading exceeds the limit, there is
no delay. When the reading drops below the limit and stays below the limit
continuously for 5 seconds, the divert relay will turn on. If the RO is off,
the divert output will be de-energized.
ALARM OUTPUT
When relay 2 has been programmed to operate as an alarm relay, the relay will
energize whenever a warning or alarm condition occurs. The relay will remain
energized as long as the warning/alarm condition is active.
ALARM LOG
The alarm log screen will show the last 5 alarm conditions. Pressing both the
Power and Alarm Silence/Reset key will display the alarm log screen. Press the
Up arrow key to advance through the logged alarms. Pressing the Enter key will
