4.2 Plumbing and Air Connections

To avoid injury, death, ﬁre, explosion, leak, or property damage:

• The ﬂuid waste from the drain connection MUST NEVER

BE reintroduced into the incoming water stream. HF

scientiﬁc recommends that operators review with local

authorities concerning the proper disposal of waste

diluted ﬂuids.

• All plumbing connections MUST BE made through the

provided stainless steel connections. Fittings should not

be modiﬁed or substituted.

• The air line and the water line MUST NOT BE reversed

in connecting the supplies. Connecting the water source

to the air line will damage the electronics and void

the warranty.

• All connections MUST BE properly installed and sealed

to ensure water tightness and preserve the ratings of

the instrument.

• The drain MUST BE open to the atmosphere for proper

operation. Ensure the vent drain remains open and is not

subject to fouling.

All wet and air connections are made with user supplied tubing using

the compression ﬁttings attached to the SSR-Ex. When using the

compression ﬁttings, follow these steps:

Step 1: Unscrew the nut from the applicable connection point.

Step 2: Remove the nut, front sleeve, and back sleeve from the

SSR-Ex.

Step 3: Place the nut, then the back sleeve, and then the front sleeve

onto the applicable tubing.

Step 4: Slide the tubing into the open connection point and

tighten the nut to secure the tubing. Refer to Figure 9.

Fitting Connections for assistance to assemble the tubing

connection. Refer to Figure 10 - Utility Connections for

assistance locating the proper ﬁtting connection on the

enclosure for the sample to be connected.

Figure 9 - Compression Fitting

When making the plumbing connections, be advised that:

• The maximum pressure for proper operation is 3 bar (45 PSI).

• The maximum sample water intake and drainage ﬂow is

150 ml/minute.

• The maximum allowable ﬂuid temperature is 55°C (131°F).

• The sample water supply does not need to be pressurized.

The SSR-Ex incorporates a pressure regulator at the water

supply inlet.

• In order to ensure that the sample measured is representative of

the ballast water, keep sample pipe runs as short as possible.

• A water shut off valve should be located close to the instrument

to allow for periodic maintenance.

• An air shut off valve should be located close to the instrument to

allow for periodic maintenance.

a convenient location near the SSR-Ex between the

compressed air supply and the SSR-Ex.

Step 2: Connect the compressed air supply to the air/ﬁlter dryer

assembly intake.

Step 3: Connect the air supply tubing from the air/ﬁlter dryer

assembly output to the SSR-Ex using the 6 mm OD ﬁtting

on the bottom of the enclosure. Reference Figure 10 - Utility

Connections.

4.3 Electrical Connections

The power must be provided by a safe remote location. All

power must be removed from a safe location while the electrical

compartment access is open. Do not reconnect power until the

electrical compartment access is closed and all captive Philips

screws have been replaced and tightened appropriately.

All electrical connections are located in the upper electrical

compartment. The electrical compartment access at the front

can and should only be opened during installation. No power

should be applied until the electrical compartment access is

closed and sealed.

The SSR-Ex has two types of electrical connections. First, the mains

power connection, which connects to the Air Sentinel II through the

cable gland on the left side of the SSR-Ex. Second, the low voltage

connections, which are made through the cable glands on the right

side of the SSR-Ex.

8

All low voltage connections should be completed before the

main power is connected to system.

All electrical connections must pass through a compression

gland. The glands can accept cabling from 11 to 21 mm in

diameter. After installation, the glands must be tightened to

ensure that the SSR-Ex maintains cabinet air pressure.

Mains power connects only to the Air Sentinel II.

No mains power should be connected directly to the main PCB.

RELAYS

4-20 mA

RMT CONNECTIONS

4.3.1 Low Voltage Connections

All of the low voltage electrical communication connections to the

instrument are made at the termination area located on the right side

of the main PCB. To access the connections, lower the access ﬂap by

loosening the captive Phillips screws. The connections are labeled and

are self-descriptive. Please follow all government recommendations and

requirements for installation of electrical connections to and between

the instrument and other peripheral devices. All terminals are designed

to accept wires in the range of 14 - 28 AWG.

4.3.1.1 Relays

Two relay alarm connections labeled COM1, NC1 & NO1 and COM2,

NC2 & NO2 are provided. The relays are rated 240VAC 2A. Operation

of this alarm is covered in section 4.2.1.5 Alarms Menu.

4.3.1.2 4 - 20 mA Analog Output

These connections are located on the mid right side of the Main PCB.

The 4 - 20 mA output is driven by a 24 VDC power source and can

drive recorder loads up to 1000 ohms. Transformer isolation is provided

on the SSR-Ex. Operation of this output is covered in section 4.2.1.3 -

Analog Output Menu.

Polarities of the connections are labeled beside this termination on the

PC board.

The recommended cable is 22 AWG shielded twisted pair. To prevent

ground loops, connect the shield at its destination. The terminal block

is removable to assist in making connections.

The 4 - 20mA is factory calibrated. An adjustment is available on the

4 - 20mA in section 4.2.1.3 Analog Output Menu. In addition to making

adjustments, these menus output continuous 4 mA or 20 mA and

can be used as a signal test. The conﬁguration mode will timeout

after 15 minutes.

4.3.1.3 Modbus

The RS-485 half-duplex (2-wire) digital interface operates with

differential levels that are not susceptible to electrical interferences.

Therefore, cable lengths up to 3000 ft can be implemented. The last

device on every bus may require a 120-ohm termination resistor to

eliminate the possibilities of signal reﬂection on the line. Do not run RS-

485 cables in the same conduit as power.

Ensure each instrument is not powered when connecting the RS-

485 line. To prevent damage to the instrument, ensure that power is

disconnected prior to making connections. The Modbus connection is

located on the lower right portion the main PCB as seen on Figure 11.

4.3.1.4 RMT

By design the SSR-Ex will only be actuated for measurement by a

remote command. The system can be set up to either be actuated

through MODBUS or by means of a remote actuation provided by the

end user.

These connections are located in the lower right corner of the main

PCB. See Figure 4 - Low Voltage Connections.

The instrument operates on user control software, where an external

control initiates each cycle. The SSR-Ex will indicate the current status

of connections using a relay contact that is closed when busy and

open when in standby mode.

4.3.1.5 Securing the Glands - Low Voltage

Low voltage connections to the instrument are made through electrical

glands located on the right side of the enclosure. Once the appropriate

low voltage wiring is inserted through the electrical gland and wiring

is secured at the terminals on the main circuit board glands on the

right side of the enclosure must be tightened to ensure wiring is

safely installed.

4.3.2 Mains Power Connections

Once all low voltage connections are made, the mains power should be

connected through the Air Sentinel II. Reference Figure 3 – Close-up of

Electrical Compartment.

4.3.2.1 Securing the Glands - Mains Power

Mains power connection to the instrument is made through an electrical

gland located on the left side of the enclosure. Once the mains power

wiring is inserted through the electrical gland and wiring is secured at

the mains power terminals of the Air Sentinel II electrical gland on the

left side of the enclosure must be tightened to ensure mains power

wiring is safely installed.

4.4 Hardware Control

The connections are labeled RMT Stby. The input has + and – polarity

connections and requires an external 24VDC control signal.

The output is simply a relay contact and is not polarized. After the

SSR-Ex completes a cycle of measurement, the unit will return to

standby awaiting another pulsed signal to measure. Alternately, 24VDC

can be continuously applied and the SSR-Ex will take readings until

the 24VDC is removed. When power is removed it will complete the

current cycle. The measured value will remain displayed until the

next measurement.

9

4.5 Modbus Control

In addition to the above mentioned Remote Standby Connections,

control can also be achieved using Modbus control. Two special

Modbus addresses are provided. The reading cycle is initiated using

the Coil Address 00005 with the default at False (0). Setting this

Address to True (1) initiates the reading cycle.

At any time the standby status can be checked at Modbus Coil

Address 00005 or Modbus Input Address 10005. False (0) indicates

standby and True (1) indicates the measurement cycle is taking place.

Control is only available from the Coil Address 00005 for more setting

information refer to Section 4.2.1.4. - Modbus Menu.

The default communication parameters are 8 bits, no parity and 1 stop

bit. Please note that all Modbus communication is via RS-485. The

instruments can support a two wire multidrop network of 255 units. If

the connection is to the master on USB, an RS-485 to USB converter

is required.

5.1 Instrument Commissioning and

Start-up

After all water, air, and electrical connections have been made, the

SSR-Ex can be powered on by turning on the power to the Air Sentinel

II. Once power is supplied to the Air Sentinel II, it will run through an

automatic three-minute purge cycle and then supply power to the

SSR-Ex. If at any time there is a loss of pressurization in the electrical

enclosure, the Air Sentinel II will remove power to the SSR-Ex.

The condition of the Air Sentinel II can be determined based on the

color of the LED lamps on its body as explained by this chart:

Once the SSR-Ex is powered on, air has been purged, and all

conﬁgurations have been completed, it is ready for use.

5.3.1 Flush Water Sample Line

Before sampling any sample water, the water line from the source

water to the enclosure must be ﬂushed to ensure that the sample line

has a representative sample and is not impacted by any debris or other

foulants. Flush the sample line by using the WATER PRIME feature

found under the SERVICE menu. When this feature is selected, the

connect- ed water sample line will automatically ﬂush water to drain.

Reference section 4.2.1.1 main menu.

5.3.2 Prepare Reagents

Prepare and install the reagents according to the instructions provided

on the reagent bottles. In the SERVICE menu, select PRIME to prime

the reagents. You can access the bottom of the enclosure to service

these items, if needed.

5.3.3 Remote Start

Once the line is ﬂushed and the reagents primed, initiate a cycle

remotely through RMT or MODBUS.

The SSR-Ex will only operate using a remote start signal.

5.4 Typical Cycle

During normal operation, the SSR-Ex will run through a timed cycle. A

simpliﬁed cycle will consist of the following sequences:

Flushing – sample ﬂow Purging – PURGE valve opens

Zeroing – no ﬂow with cuvette full

Adding Reagents – one pulse of the reagent pumps

Sample Reaction – reaction of reagents with oxidant sample Reading

resulting sample – no ﬂow with cuvette full

Purging – PURGE valve opens to remove the reacted sample and water

The cycle above is simpliﬁed and does not describe all the actions

and testing that occurs. The CPU continuously diagnoses the entire

system for correct operation and sample water ﬂow. If an error occurs,

a message is posted on the LCD screen and is indicated on a Modbus

address. Alarm contact closure can be user conﬁgured to provide an

alarm in the event of an error message.

5.5 Observe Operation

Observe the process in the optical assembly, you should see a vortex

of water form as the SSR-Ex ﬂushes water through the cuvette, then

the unit will stop water ﬂow and “zero” on the source water, ﬂush again

and then actuate the reagent pumps and take

6.0 Maintenance

Under normal operating conditions, it is recommended that the

main enclosure door is closed. If the electrical or power devices in

the purged (upper) section of the enclosure needs to be accessed

for service, ensure all power has been removed from a safe location

before accessing the electrical or powered devices in the electrical

enclosure.

The SSR-Ex instrument is sectioned such that all the electrical or powered

devices are in the upper, purged section of the enclosure, while the lower

(wetted parts) section contains no power at all and can be operated and

maintained in a safe condition even with the main enclosure door open. In

the interest of safety, if the electrical or power devices in the purged (upper)

section of the enclosure needs to be accessed for service, ensure all power

has been removed from a safe location prior to accessing the electrical or

powered devices in the electrical enclosure. All components in the lower

(wetted parts) section of the enclosure can be accessed for service or routine Figure 13 - Pressure regulator and T-strainer

6.1 Calibration

Calibration kit (Cat. No. 28144S) includes:

125 ml of zero solution (solution #1)

125 ml of calibration solution (solution #2) 1 each replacement cuvette

The SSR-Ex instrument was tested and calibrated prior to leaving the

factory. The instrument operates from a pre-determined calibration

curve for high accuracy of residual oxidant concentration. It is not

necessary to recalibrate to maintain stated accuracy speciﬁcations. If

re-calibration is required by a regulatory authority, calibration can easily

be accomplished in the ﬁeld using the procedure below.

Step 1: Ensure the supply water is shut off. From the control buttons,

enter the calibration screen. Follow the on-screen instructions.

Step 2: Disconnect the black tubing from the pressure regulator to

the pump. Some water may drain from the regulator, this is

normal and it may be appropriate to use a container to catch

the small volume of water.

Step 3: Insert the black tube into solution #1. This is used to set a

zero reference. Follow the instructions on the display.

Step 4: When the SSR-Ex has completed the zero procedure you

will be instructed to move the tube to solution #2. Follow the

instructions on the display.

Step 5: The SSR-Ex will take a reading of the solution. If this reads

from 9-11 mg/l (PPM), the instrument is operating within

the stated speciﬁcations and no further action is required.

If the reading is outside of this range the SSR-Ex will allow

you to make an adjustment to bring it into range. Follow the

instructions displayed on the SSR-Ex.

Step 6: Restore the black tube to the pressure regulator and turn

the water supply back on. Check for leaks before closing the

enclosure door.

maintenance, while the SSR-Ex instrument is powered, air supplied, and

while the main enclosure door is open. Under normal operating conditions,

it is recommended that the main enclosure door is closed. In cases where

the SSR-Ex instrument is in an environment considered to be Zone 0 for a

period of time, power and air to the instrument must be removed.

General Condition Check - Once a month check the general condition

of the instrument in operation by opening the enclosure door and

visually inspecting the instruments wet chemistry section components to

conﬁrm proper operation and to also check for any leaking components

or other concerns. The wet section components can be accessed for

maintenance, reagent replacement and visual inspection during voyages.

Speciﬁc condition of use: Parts of the enclosure are non-conducting

and exceed the maximum permissible resistance according to

the IEC 60079-0. Therefore, to avoid electrostatic charge build-

up, it must not be rubbed or cleaned with solvents or a dry cloth

when installed/used within a potentially explosive atmosphere.

16

6.2 Cuvette Replacement

HF scientiﬁc recommends that the cuvette be replaced annually or if it

appears badly soiled or discolored at any time. It is suggested to place

a covering over a ﬂoor grate if the instrument is installed over a grate.

To replace the cuvette:

Step 1: Press SERVICE to stop the ﬂow of sample water and drain

the cuvette.

Step 2: Ensure the source water is turned off.

Step 3: Turn counterclockwise, but do not completely remove, the

knurled ﬁtting on top of the optics system to loosen the

cuvette. Occasionally it is necessary to very gently rotate the

cuvette on the O-rings to facilitate removal. Once the cuvette

rotates easily on the O-rings carefully remove the cuvette.

There is a spring installed in the optical block to facilitate

removal of the cuvette.

Step 5: Reverse the procedure to install a new or cleaned cuvette.

Step 6: Retain the removed cuvette for future use if it can be cleaned.

Refer to Figure 5 - Wet Chemistry Area of Enclosure

Install the new cuvette by pushing it ﬁrmly but gently to seat it on the

O-rings, carefully turn the knurled top clockwise until the cuvette is held

level and securely against both the top and bottom O-rings, do not

overtighten. Return to normal operation.

6.3 T-Strainer Cleaning

The T-strainer is integral to the instrument and must be checked when

changing the reagent. When necessary the T-strainer screen and bowl

must be cleaned. The T-strainer is clamped to the door and does not

require removal to be cleaned. You may want to place a container

under the instrument to catch the water and debris during cleaning.

Step 1: Press SERVICE to stop the ﬂow of sample water and drain

the cuvette.

Step 2: Ensure the source water is turned off.

Step 3: Disconnect the top (bowl) of the T-strainer by turning

counterclockwise.

Step 4: Remove and clean the screen and the bowl and then

reassemble.

Step 5: Be sure to tighten the bowl of the strainer.

Step 6: Turn source water back on.

Step 7: Return to normal operation.

Step 8: Check for any leaks.

The T-strainer screen (Cat. No. 28625) may require replacement after a

period of time or as needed.

6.4 Adjusting the Pressure Regulator

The pressure regulator is factory set and it should not be necessary to

adjust it in the ﬁeld.

6.5 Installing New Reagent in the SSR-Ex

Use caution when changing the reagents, as they are corrosive. These

reagents may stain clothing. After changing the reagents, operators

should wash their hands.

Step 1: Press SERVICE to stop the ﬂow of sample water and drain

the cuvette.

Step 2: Ensure the source water is turned off.

Step 3: Remove both reagent bottles by unscrewing cap assembly.

Step 4: The buffer is installed on the right and the indicator is installed

on the left.

Step 5: Once bottles are secure in the bracket, wrap the Velcro

around both bottles to ensure they do not move.

Step 6: Screw cap on the bottle and ensure a tight ﬁt. Ensure tubing

is fully submerged at the bottom of the bottle.

Step 7: Follow the PRIME procedure under the SERVICE menu.

This will draw enough of each reagent to completely prime

the tubes and replace any old solution. The system will

automatically return to normal operation after it completes the

prime.

6.6 Replacing the Peristaltic Sample

Pump Head

The pump head assembly can be replaced. Recommended replacement

for the pump head assembly is annually. It is replaced as a complete

assembly, not just the pump tube. The pump is located in the upper

right of the wet enclosure.

Step 1: Press SERVICE to stop the ﬂow of sample water and drain

the cuvette.

Step 2: Ensure the source water is turned off.

Step 3: Squeeze the right side of the pump housing, this will release

the pump head from the bracket and a new pump head can

be installed.

Step 4: Disconnect the inlet and outlet sample tubes from the pump

once it has been removed from the pump base taking care to

note which tube connects to which side of the pump head.

Step 5: Connect the inlet and outlet sample tubing to the new pump.

Step 6: Carefully replace the pump head in the enclosure.

6.7 Instrument Storage

If the SSR-Ex is relocated or will be inactive for long periods of time

(several months).

Step 1: Press SERVICE to stop the ﬂow of sample water and drain

the cuvette.

Step 2: Ensure the source water is turned off.

Step 3: Remove the reagents.

Step 4: Flush the reagent sample lines with distilled water. Flush the

reagent system.

Step 5: Remove power by disconnecting the mains power.

Step 6: It is usually a good idea to disconnect or shut off the source

water for the duration of storage.
