Introduction

The PHUCN600 series multi-parameter controller is a microprocessor based controller
capable of measuring one of the following parameters, pH, ORP or conductivity.

When shipped from the factory, the PHUCN600 series is not set to measure any one
parameter. When the PHUCN600 series is powered up for the first time, it will display
the meter selection screen where the meter type must be selected. (refer to section 4.6
Meter Selection)

This meter selection screen will only be displayed when the unit is powered up for the
first time.

After the user selects a meter type the PHUCN600 series will remain set to that meter
type until it is changed with the meter selection menu function in the Utilities menu.

To return the PHUCN600 series to its factory settings, the user must re-select the cur­rent meter type from the meter selection menu function. This will override all set-points
and return all settings back to the factory settings.

The PHUCN600 User’s menu has been divided into five main categories

- Calibration, used to calibrate the PHUCN600 series with the selected sensor

- Utilities, Used to manually control or override the outputs.

- Setup, used to configure the PHUCN600 series’ many options

- Diagnostics, used to troubleshoot any problems with the PHUCN600 series

- Outputs, used to configure the PHUCN600 series’ outputs.

There are two displays on the PHUCN600 series. A bright LED numeric display with bar
graph on the outside front panel, and a 2-line, 16-character LCD display on the inside.
The LED readout on the outside panel can be seen several yards away. The distinc­tive,color-coded bar graph will immediately indicate if you are within the process param­eters that you set (green), if the control relays are on (yellow) and if you are in alarm
condition (red). This makes diagnosing pump and alarm malfunctions easy. All configu­ration and control functions are performed on the LCD menu on the inside front panel.

A universal mounting kit is included for surface,panel and pipe-mount applications. The
1/4 DIN enclosure makes panel-mount cutouts and engineering simple.

PHUCN600 series is packaged in a rugged NEMA 4X polycarbonate enclosure making
it ideally suited for heavy-duty applications such as industrial wastewater neutralization,
municipal water and wastewater, pulp and paper, and process control.

3.1 Conduit Connections

The PHUCN600 series has four 1/2” conduit holes, 2 on each side of the enclosure as shown
on fig. 2.1. The unit is shipped with these holes plugged with liquid tight conduit seals. These
must be left in unused holes to maintain the NEMA 4X integrity. Use approved conduit hubs to
connect the conduit, connect these to the conduit before connecting to the enclosure.

Wire Specification

: Size and fuse wire according to local electrical code. Maximum current not

to exceed 10A when used to power auxillary decvices powered via internal connections.

3.2 A.C. Power Connections

Caution: This instrument uses 120 or 240 50/60 Hz AC power. Opening the enclosure
door exposes you to potentially hazardous line power voltage which might be pres­ent on the terminals of plug P3 and P4. Always remove line power before working in
this area. If the relay contacts on P4 are powered from a seperate source from the
line power on P3, be sure to disconnect that power before proceeding. The
PHUCN600 flip out door contains only low voltage and is safe to handle.

The PHUCN600 series is available in two power models.
The PHUCN610 is designed to operate at 240 VAC.
The PHUCN601 is designed to operate at 120 VAC.
To connect power to the PHUCN600, remove the terminal block plug P3 and connect the
wiring as shown below.

The drawing shows the connections for the 5-wire Differential probes. The cable should be run
in a conduit separate from AC power wires, and via a separate conduit hole.

Note: Leave 4” to 6”
slack for all wires
connected to the
terminals of P6.
Slack required so
that wires do not
interfere with open­ing or closing of the
front door.

If the cable of the
differential probe is
cut, the blue
wire is not used.

CAUTION:

Always remove line
power before
unplugging or
plugging in the P6
connector

Once connected, step through the LCD menus to
select the probe in the order shown. The first two
steps may be skipped if the meter is already con­figured for pH or ORP and a Differential Probe.
When using a pH probe, it is important to ensure
that the PHUCN600 is reading the probe temper­ature correctly for accurate temperature compen­sation. The ORP probe does not require tempera­ture compensation, although the PHUCN600 can
display process temperature measured by the
probe. The factory temperature calibration is usu­ally accurate enough that no adjustments are nec­essary.

3.7 Relay connections

The PHUCN600 series controller has three internal relays. Relays A and B are for control, the
Alarm Relay can be configured for alarm functions or as an additional control relay.

The connections to the relays are shown in the drawing.
Note that the AC power is internally connected to the
relay terminal plug P4. This is used to provide 120V or
240V AC power for the relay contacts.

Wire Specification

: Size and fuse wire accroding to local

electrical code. Wire size not to exceed 14 AWG.

WARNING

The contacts are rated at 10 amp N.O. and 5 amp N.C. Do
not exceed this rating.When switching larger currents, use an
auxillary relay switched by the controller relay to extend the
controller relay life. If the relays are controlling an inductive
load, use appropriate transient suppression at the load.

Section 3 - Electrical Connections and Setup

3.8 RELAY A and B Setup

(LCD MENU SECTIONS - pH: 4.18 & 4.19, ORP: 5.17 & 5.18,
Conductivity: 6.18 & 6.19)

Relay A & Relay B on the PHUCN600 series are
SPDT dry contact relays. They are configurable to
operate in response to rising or falling process val­ues. Each relay has independently adjustable on
and off set-points, cycle times, and fail-safe
options.

The operator would use the control relays if the
device to be controlled is a simple on/off device.
For example a pump, solenoid valve, fan, or an
indicating light.

The control relays have 6 user configurable set­tings:

CYCLE OFF time
amount of time in seconds that the relay will be de­energized, it can be set between 0 and 600 sec­onds. To disable the cycling feature set the cycle
off time to 0.

VERFEED TIMER: The overfeed timer is

O
designed to help safeguard against a process or
instrumentation error causing one of the control
relays to remain energized for extended periods of
time.

When enabled, the overfeed timer will time out if
the control RELAY OFF set point is not reached
inside the overfeed time out. The control relays will
de-energize, the alarm relay will energize and an
LED will flash at the front.

: The CYCLE OFF time is the

DIRECTION

: The relay can be set to control either
a rising or falling process. If for example the relay
is set to control a falling process, the ON set-point
must be set lower than the OFF set-point. If the
relay is set to control a falling process, the
PHUCN600 will not allow the RELAY OFF set
point to be set lower than the RELAY ON set-point.
This rule will also apply to a rising process.

Y ON set-point: This is the process value at

RELA
which the relay will energize.This value can be set
anywhere between 0-100% of the range.

Y OFF set-point: This is the process value at

RELA
which the relay will de-energize.Depending on the
direction for which the relay is configured, the
RELAY OFF set-point will only be setable in a lim­ited range.

CYCLE ON time

: To obtain a tighter process con­trol, and limit over-shoot, the control relay can be
set with the cycling feature. This feature, if
enabled, will cause the control relay to cycle when
the process is between the RELAY ON set-point
and RELAY OFF set-point. The cycle on time is the
amount of time in seconds that the relay will be
energized. It can be set between 0 and 600 sec­onds.

AILSAFE: The FAILSAFE feature is designed to

F
reverse the normal action of the control relay.

When the relay is set to FAILSAFE OFF the relay
will operate as a normal relay. When the relay is
de-energized the NO contacts are open and the
NC contacts are closed. Thus the device connect­ed via the NO contacts will be off. When the relay
becomes energized the device will be on.

When the relay is set to FAILSAFE ON, the normal
action of the relay is reversed. Thus the NO con­tacts act as the NC contact and the NC act as the
NO. The device connected to the NC contacts will
be energized when the RELAY ON set-point is
reached. The relay will be de-energized but
because it is acting in reverse the device will be
energized. When the RELAY OFF set-point is
reached the relay will energize and the device
connected to the NC contact will de-energize.

The purpose of the Fail Safe option is to have the

3.9 ALARM RELAY Setup

(LCD MENU SECTIONS - pH: 4.20, ORP: 5.19, Conductivity: 6.20)

The third relay (Relay C) is used as an alarm relay.
The alarm relay on the PHUCN600 is a SPDT dry
contact relay.

This relay will respond to both a rising and falling
process. The alarm relay will act as a low alarm
(falling process) and a high alarm (rising process).
Both relays will have independently adjustable on
and off set-points. The ALARM ON set-points will
always be set before the ALARM OFF set-points.
The controller will not let the user input a value
below the ALARM ON set-point. The same rule
holds true for the high alarm.

The control relays have 5 user configurable set­tings:

ALARM LO
value that will cause the relay to energize. This
value can be set anywhere between 0-100% of the
range.

ALARM LOW OFF set-point: This is the value that
the process must reach in order to de-energize the
alarm relay after it has dropped below the ALARM
LOW ON set-point.This value must be higher than
the ALARM LOW ON set-point.

ALARM HIGH ON set-point
value that will cause the relay to energize. This
value can be set anywhere between 0-100% of the
range.

ALARM HIGH OFF set-point
the process must reach in order to de-energize the
alarm relay after it has increased over the ALARM
HIGH ON set-point. This value must be lower than
the ALARM HIGH ON set-point.

W ON set-point:This is the low process

: This is the process

: This is the value that

ALARM SET
ON set-point is set higher than the factory default
ALARM LOW OFF set-point, when the user
advances from the ALARM LOW ON set-point to
the ALARM LOW OFF set-point the shark will
adjust the ALARM LOW OFF set-point to be equal
to the ALARM LOW ON set-point. If the user then
tries to decrease the ALARM LOW OFF set-point
the controller will display the ALARM LOW
ALARM setup error screen.

This screen will be displayed for 10 seconds, then
return back to the setup screen that was previous­ly displayed. If the user presses the down key
again the error message will be displayed again
for 10 seconds. The user must accept the LOW
OFF set-point, equal to, or greater than the LOW
ON set-point.

The same conditions apply to the ALARM HIGH
set-points. Except the ALARM HIGH OFF set­point must be lower than the ALARM HIGH ON
set-point. If the user tries to increase the ALARM
HIGH OFF set-point higher than the ALARM HIGH
ON set-point the High Alarm setup error screen
will be displayed.

3.10 MANUAL TEST MODE

(LCD MENU SECTIONS - pH: 4.4, ORP: 5.3, Conductivity: 6.4)

Once the relays are configured, the setup can be
tested using Manual Test Mode to simulate process
changes.

MANUAL TEST MODE is used to simulate a process
reading in order to verify the correct response of the
outputs. When in the MANUAL TEST MODE, the
relays and outputs are no longer placed on hold as
they are when in the rest of the menu. The relays and
outputs will react to the simulated change in process
as if the controller was in RUN MODE.

Note that when the user exits the MANUAL TEST
MODE, the relays and outputs will remain in the
MANUAL TEST MODE state until the user enters
RUN MODE.

3.11 RELAY OVERRIDE

(LCD MENU SECTION - pH: 4.5, ORP: 5.4, Conductivity: 6.5)

Relay Override is used to manually override the state
of the relays. The user is able to set the operating
mode of the relay as AUTO/ON/OFF (the default and
RUN MODE states are AUTO).

This feature can be used to energize or de-energize
the relays to manually correct the process, or to shut
down an ancillary device to perform maintenance.
When in the RELAY OVERRIDE mode, the relays are
no longer placed on hold as they are when in the
other menus.

Note that if the RELAY AUTO RETURN is set to
"ON", the controller will place all the relay settings
back to AUTO 10 minutes after the controller returns
to the run mode..

(LCD MENU SECTIONS - pH: 4.21 & 4.22, ORP: 5.20 & 5.21,
Conductivity: 6.21 & 6.22)

The PHUCN600 Series Controller
has two 4 to 20mA outputs, electri­cally isolated from each other and
ground. Either output can source
current into a maximum of 800
ohms.

Channel 1 (the primary output) is
located on the flip out door, terminal
plug P6. Channel 1 is dedicated to
track the process and has fully inde­pendent and fully adjustable 4 & 20
mA output setpoints.This will enable
the operator to span the output over
the desired range.

Figure 3.7 Connections for the 4-20mA outputs

Channel 2 (the secondary output) is
located in the enclosure terminal
plug P1. Channel 2 can be selected
to track the process value or tem­perature and has fully independent
and adjustable 4 & 20 mA output
setpoints.

Both Channel 1 and 2 can be pre­cisely trimmed through the LCD
menu for precision applications.

The drawing shows the connections
for both outputs.

Wire Specification

: 22 AWG 7/30,

insulation 0.010”

Note: Leave 4” to 6” slack for all
wires connected to the terminals of
P6. Slack required so that wires do
not interfere with opening or closing
of the front door.
