ABOUT THE HYDRORANGER PLUS

Reservoir

Screen Rake

The HydroRanger Plus is to be used only in the

manner outlined in the instruction manual.

The HYDRO+ includes the features of the successful Milltronics "HydroRanger 1"
PLUS a variety of new features, incorporating advances in electronic component,
manufacturing, and software technology.

This multi-purpose microprocessor based level monitor contains numerous features
ideally suited for liquid monitoring and pump control applications.

Wet Well

A HYDRO+ level monitor, utilizing a single ultrasonic transducer (ordered separately),
accurately monitors level without contacting the surface monitored.

The HYDRO+ provides the transmit pulse to the transducer. The transducer emits
ultrasonic pulses in a narrow beam, perpendicular from the transducer face. The
HYDRO+ measures the time between pulse emission and reflection (echo) reception,
to calculate the transducer face to monitored surface distance.

The transducer internal temperature sensor is used to automatically compensate
for sound velocity variations due to air temperature changes within the
measurement range.

PL-507 6

The HYDRO+ monitors levels 0.3 to 15 m (1 to 50 ft) from the transducer face, with

outstanding accuracy, usually within 0.25% of range. (Ensure the transducer selected
suits the material and measurement range monitored).

TM

This versatility is accomplished by Milltronics patented Sonic Intelligence

, providing

high measurement reliability, regardless of operating conditions.

LCD

The HYDRO+ provides the following

(Liquid Crystal Display) Readings:
» Level, space, distance, volume, or remaining capacity in open or closed vessels.
» Differential level across a channel filter or screen (2 transducers required).
» Average level in a large vessel with an uneven material surface (2 transducers).
» Head, flow, or totalized flow in free flowing open channels.
» Pumped volume from wet wells or into reservoirs.

The HYDRO+ relays and/or mA output may be used as preset (or programmed as
desired) to activate alarms, pump controls, chart recorders, or virtually any process
control equipment.

PLC

The HYDRO+ infrared interface permits one programmer to be used for any number
of HYDRO+ level monitors. Upon programming completion, the programmer may be
locked away for programming security. All Operator programming is stored in
non-volatile memory, unaffected by power interruption.

While the HYDRO+ is typically used to monitor liquid level, any process which
requires a distance measurement or object presence/lack of presence (within the
system maximum measurement range) is a candidate for HYDRO+ application.

Refer to APPLICATIONS for detailed descriptions of a small sample of process
measurement requirements to which the HYDRO+ may be applied.

POWER

The HYDRO+ uses 100, 115, 200, or 230 Vac or 9 to 30 Vdc power. If ac and dc
power are supplied, the HYDRO+ draws power from the ac supply. In the event of an
ac power interruption, the dc supply is used until ac power is restored.

IMPORTANT!

Before applying ac power (mains), ensure the correct voltage is selected!

Never operate the HYDRO+ with the enclosure lid open,

or with the ground (earth) wire disconnected!

Before applying power to the HYDRO+ for the first time,

ensure any connected alarm/control equipment is disabled

until satisfactory system operation and performance is verified!

PROGRAMMING

Those not previously familiar with the HYDRO+, may wish to use the step by step
initial start up procedure illustrated in the HYDRORANGER PLUS QUICK START
GUIDE provided. Then, reference to the remainder of this instruction manual is only
necessary if operation modification is required.

All programmable features are identified by a Parameter Number, which has a preset
Parameter Value. Programming is accomplished by altering the Parameter Value of
specific Parameter Numbers to obtain the RUN mode operation desired.

When applicable, the Point Number to be affected, must be identified before the
Parameter Value is altered.

See APPLICATIONS for common HYDRO+ programming requirements. If more

detailed parameter information is required, see PARAMETERS .

To enable the programmer
interface of the HYDRO+
rack or panel mount version,
press the key on the
front panel.

Program enable is confirmed
by the icon appearing in
the display. To disable
programming, press again.
Program disable is confirmed by
absence of the icon in the

internal temperature sensor and a maximum range of 15 m (50 ft) or less, the preset
Transducer (P004) value is suitable for operator orientation with HYDRO+ operation.

If "Error" and the transducer terminal numbers are displayed, the transducer does not
have an internal temperature sensor. See Transducer (P004) options.

APPLICATIONS

WET WELL CONTROL (Pump Down)

Typically, wet wells are used to temporarily hold storm and/or waste water. When the
surface reaches a high level setpoint, the wet well is pumped down. The discharge
goes on to another wet well or directly to the treatment facility.

The HYDRO+ provides wet well control with only minimal application programming.
For the following example, we’ll assume Empty (P006) was set from the transducer
face to the wet well floor. (To monitor wet well overflow, see the note at the end of the
OCM Application example).

(If the transducer cannot be located to avoid acoustic beam interference from the
pumps, set Empty (P006) from the transducer face to the top of the pump(s).

OPERATION

For this example we’ll assume:

P001 Operation is set to "level" (P001 = 1).
P003 Measurement Response is set to "medium" (P003 = 2, preset).
P006 Empty is set for 6.000 metres.
P007 Span is set for 5.000 metres.
P071 Failsafe Material Level is set for "HI".
P100 Relay Set Up is set for Wet Well 1 (P100 = 1).

a) high alarm is to indicate failsafe operation.
b) lead pump starts (as preset) at 70% (3.5 m).
c) high alarm trips on (as preset) at 90% (4.5 m) and off at 85% (4.25 m).
d) normal wet well filling rate is 0.3 m/minute.
e) back up system takes over if level reaches 5.5 m.
f) at 9:15 am, the HYDRO+ transducer cable was accidentally cut.

APPLICATIONS

e.g. 09:15:00 am Echo lost at 2.2 m, pump(s) turn off, countdown begins

09:25:00 am Failsafe activated, reported level advances at 1 m/min (P003).
09:26:00 am backup control takes over, actual level = 5.5 m (and falling).
09:27:18 am HI alarm trips on, reported level = 4.5 m.
09:27:48 am HI alarm still on, reported level = 5 m.

APPLICATION ASSISTANCE

The preceding examples describe only a few ways in which the HYDRO+ can be
applied to process measurement requirements.

The HYDRO+ can be used to monitor and/or activate alarm/control relays for almost
any process (within the temperature, measurement range, and chemical immunity
capabilities of the system) where a distance measurement or determination of
presence vs. lack of presence of an object is desired.

By thoroughly reviewing the PARAMETERS sections, you may identify some
interesting ways of using the HYDRO+ to monitor specific processes.

Milltronics has many years experience applying ultrasonic level measurement to a
variety of processes in the mining, aggregate, lumber, grain, chemical, pulp and
paper, water, and waste water industries.

If you encounter a difficulty applying the HYDRO+ to a process measurement
requirement, or successfully apply the HYDRO+ to a "unique process" we may have
never considered, contact Milltronics or your local distributor.

FAILSAFE PARAMETERS (P070 to P072)

As preset, if Failsafe Operation is activated, the display, alarm relays, and the mA
output are held at their last "known" values, and control relays de-energize, until a
valid measurement is regained.

To automatically operate alarms / controls under these conditions, alter the following
parameters as required.

FAILSAFE OPERATION

If Failsafe Operation is not required, proceed to RELAY PARAMETERS.

If a difficulty occurs, the display, relay status, and mA outputs are held at their last
"known" values and the Failsafe Timer is activated.

When a valid measurement is made before the Failsafe Timer (P070) expires, the
HYDRO+ advances to the "new" material level, per the Max Empty / Fill Rate (P700 /
P701, preset by Measurement Response, P003), and the timer resets.

If the timer expires, the HYDRO+ advances to the Failsafe Material Level (P071), per
Failsafe Advance (P072), operating relays per Relay Failsafe (P129) and the mA
output per mA Failsafe (P219).

When a valid measurement is made after the timer expires, the HYDRO+ advances to
the "new" material level, per Failsafe Advance, and the timer resets.

If Failsafe Operation is activated frequently, see TROUBLESHOOTING .

PUMP SETPOINT MODIFIERS (P121 and P122)

P121 (G) RATE PUMP

Use this feature when more than one relay is set for a "Pump" Relay
Function (P111), to start pumps by rate rather than by level.

During operation, when all pumps are OFF and the level reaches the
Relay A Setpoint, the first pump is turned ON.

If more than one relay (5 max.) is set for a "pump" Relay Function, pumps
will be started in sequence until the level changes at a rate greater than the
corresponding Filling (pump up)/Emptying (pump down) Indicator (P702 /
P703) value, or until all pumps are running (which ever occurs first).

(If the surface is within 5% of Span (P007) from the Relay B Setpoint, and
rate falls below the P702 / P703 value, the pump is held "OFF").

This feature is preset to " on " if Relay Set Up is set for " Wet Well 2 " or

ENERGY SAVING EXAMPLE

( Wet Well, " Pump Down " Application )

Normal Operation

During low energy cost period Relay A / B
Setpoints (P112 / 113) are used to initiate pump
starts and pump stops.

Peak Lead time (P143)

Regardless of the Relay A Setpoint, pump
starts are initiated, and level falls to the
Relay B Setpoint.

Peak Start Time (P141)

Low level for start of high energy cost period. Now
Relay A / B Setpoints are disregarded. Pumping is
initiated only if the Peak A / B Setpoints (P144 /
P145) are reached. *

PARAMETERS

Peak End Time (P142)

With the high energy cost period now over, Peak
A / B Setpoints are disregarded. Pumping is
initiated as the normal A / B Setpoints are reached.

* When the Peak A Setpoint is not reached, no energy is used during the " high

cost " period. If the Peak A Setpoint is reached, the Wet Well is only pumped

down to 60 %, thereby minimizing " high cost " energy usage.

Instrumentation Technicians familiar with Milltronics echo processing techniques.

Use these features to record and save a total of up to 10 Echo profiles, initiated
manually (P330), or automatically (P331 et al). Each record is time and date stamped
as to when the profile was saved. See Scope displays (P810) for echo profile viewing
hardware / software requirements.

If 10 Echo Profiles are already saved, addresses 1 through 10 are filled, the oldest
automatically initiated record is overwritten. Manually initiated records are not
automatically overwritten. All records are automatically deleted in the event of a
power interruption.

When a record is displayed, results are based on current programming (which may
have been altered since the record was saved). This permits the effect on the echo
profile to be observed when changing an echo parameter.

P330 PROFILE RECORD

In addition to serving as a library for profile records, this parameter provides
two functions:

» manually records and saves echo profiles
» displays an echo profile, recorded manually or automatically,
e.g. via an oscilloscope.

To select a record address:

until address index is enabled.

selects the desired address, 1 to 10, and displays the
associated parameter value:

‘- - - -’ = no record

‘ x# ’= record

where: x = A, automatically initiated

# = transducer number
