Installation and Startup

Your Circulating Bath with Advanced Digital Temperature Controller is designed to be simple to set-up
and install. The only tools required are a No.1 Phillips-head screwdriver and a container for adding water
or other suitable fluid to the bath reservoir.

General Site Requirements

Locate your Circulator on a level surface free from drafts and direct sunlight. Do not place it where there
are corrosive fumes, excessive moisture, high room temperatures, or in excessively dusty areas.

Refrigerating / Heating Circulators must be 10.2 cm / 4 inches or more away from walls or vertical
surfaces so that airflow is not restricted.

Avoid voltage drops by using properly grounded power outlets wired with 14 gauge or larger diameter
wire and if possible, be close to the power distribution panel. The use of extension cords is not
recommended; this will reduce the potential for problems caused by low line voltage.

Adding Liquid to the Bath Reservoir

WARNING: When using Class III flammable fluids per DIN 12876-1, the user must attach the

following warning labels to the front of the unit so that they are well visible:

WARNING: Always drain all fluid from the reservoir before moving or lifting your Circulator. Be sure
to follow your organization’s procedures and practices regarding the safe lifting and relocation of
heavy objects.

WARNING: To avoid the potential for burns, allow the Circulator to cool completely before cleaning
or performing any maintenance.

Pump Inlet and Outlet Connections

WARNING: When connecting tubing to an external application, it is the user’s responsibility to make

sure that the tubing and fittings connected to the Circulator are suitable for the fluid being used and
the temperature range of operation.

CAUTION: The Circulator’s bypass tubing is secured to the fluid inlet and outlet connections by high
temperature nylon hose clamps, which can be removed by carefully cutting them with diagonal
cutters.

CAUTION: Secure the tubing to the inlet and outlet fittings using hose clamps with a minimum ID of
7/8 inch (22 mm). Do not operate the unit without hose clamps.

WARNING: If the Circulating Bath will not be used for external circulation, the inlet and outlet ports
should remain connected using the Buna N bypass tubing provided with the unit.

The pump inlet and outlet ports are female ¼ inch NPT connections that permit use of barbed tubing
adapters or hard plumbing fittings. ½ inch (13 mm) ID tubing may also be slid over these connections and
held in place with a hose clamp (minimum 7/8 inch / 22 mm ID).

If the pump inlet and outlet are not used for external circulation, the Bypass Tubing provided with the unit
should be left in place in order to optimize fluid mixing within the reservoir.

The nylon barbed tubing adapter fittings supplied with the unit are intended for applications from

-40° to 93°C. For applications above 93°C, brass, stainless steel, or Teflon

®

fittings are recommended. ¼

inch NPT to M16 stainless steel male adapter fittings are provided with all 50Hz models.

NOTE: The use of quick-connect fittings is not recommended as they typically restrict flow rate.

110-513 PSC/EN 16

www.GlobalTestSupply.com

External Closed Loop Circulation

Connect the pump inlet and outlet to the external apparatus. To maintain adequate flow, avoid restrictions
in the tubing. When connecting the Circulator to more than two closed loops, the use of a manifold made
of “Y” adapters to divide the fluid into multiple banks is recommended. After setting up multiple closed
loops, check for adequate flow at the return manifold of each loop and check that the bath fluid is at an
adequate level. A booster pump may be added to closed loops without damaging the Circulator’s pump.

The temperature control stability of a closed loop system is better at the external apparatus than in the
Circulator reservoir (provided the control point of the apparatus represents a constant load and is well
insulated). For example, if you circulate fluid through a viscometer at 50°C, the temperature variation
observed in the Circulator reservoir may be ±0.1°C while the temperature variation in the viscometer may
be only ±0.05°C.

Although temperature stability is generally better at the external apparatus control point, depending on the
length of tubing used and the efficiency of the insulation, the actual temperature reading at the external
apparatus may be slightly different than the temperature reading at the Circulator reservoir.

Open Loop Circulation

The duplex (pressure/suction) pump permits circulation to and from an external open bath. To prevent
siphoning when the Circulating Bath is turned off, position both baths so that the two fluid levels are at the
same elevation.

Connect the pump inlet and outlet to the external bath using tubing of the same diameter and length. The
same size fittings should also be used on both the inlet (suction) and outlet (pressure). This helps ensure
a balanced flow. A restricting valve or pinch clip should be installed in the pressure (outlet) tubing and
adjusted to match the return suction (inlet) flow rate. Cut the external end of the suction tube into a “V”
shape so that the tube will not seal itself against the wall of the external tank. Both the pressure and
suction tubing should be securely fastened to the external tank to prevent movement during use.

When using flexible tubing, the suction tubing must have a wall thickness that will not collapse under
vacuum, particularly when going around bends.

Circulating Bath Height Regulation — Position the ends of the pressure and suction tubes at the desired
maximum fluid level in the external bath and fill the bath to that level. Fill the Circulating Bath to a height
one inch (25mm) below the top of the reservoir. Start the pump and adjust the restricting valve/pinch clip
on the pressure tubing until the liquid height in both baths remains constant. Add fluid to the baths as

Routine Maintenance and Troubleshooting

Drain Valve

Drain Port

WARNING: Always turn your Circulator OFF and disconnect it from the electrical power outlet before
performing any maintenance or service.

WARNING: To avoid the potential for burns, allow the Circulator to cool completely before cleaning
or performing any maintenance.

Maintaining Clear Bath Water

Optimum temperature and moisture conditions for algae growth exist when using water as a bath fluid. To
prevent algae contamination and minimize the frequency of draining the reservoir, an algaecide such as
Polyclean Bath Algaecide (004-300040) should be used.

WARNING: Do not use chlorine bleach.

Draining the Bath Reservoir

WARNING: Bath fluids should be stored and disposed of according to applicable laws and

regulations.

Refrigerated / Heating and Heat only Circulating Baths

Refrigerated / Heating and Heat only Circulating Baths are equipped with a drain valve and port located
either beneath the front access panel or on the right hand side of the unit.

To drain fluid from the bath, attach a short length of suitable 0.45 inch / 11.5 mm ID tubing to the drain
port and secure it using a hose clamp with a minimum ID of 0.7 inch / 18 mm. Open the drain valve using
a flat blade screwdriver. When closing the valve, do not over tighten.

WARNING: Be sure to close the drain valve before refilling the bath reservoir. Do not over tighten.

Safety Set
Thermostat



Your Circulator incorporates over-temperature and low liquid level protection according to IEC 61010-2-

010. For optimum safety, these systems should be checked at least every six months for proper
operation. These checks must be performed with the unit running.

Over-Temperature Protection

1. Press

until the Safety sub-menu is displayed.

2. Using a No.1 Philips head screwdriver, rotate the Safety Set
Thermostat on the rear of the Temperature Controller until the unit
shuts down. The Safety Set temperature at this point should be the
same as the actual bath temperature.

3. Return the Safety Set temperature to the desired over-temperature
value.

4. Press the

Low Liquid-Level Protection

1. Set the temperature set point to ambient and allow the Circulator to stabilize at that temperature.

2. Increase the temperature set point to about 5°C above ambient and slowly drain fluid from the bath.

3. Continue draining fluid until the unit shuts down. The fluid level at this point should be approximately

3.75 in. / 9.5 cm below the underside of the Circulator’s top deck.

WARNING: It is the user’s responsibility to properly decontaminate the unit in the event hazardous
materials are spilled on exterior or interior surfaces. Consult the manufacturer if there is any doubt
regarding the compatibility of decontamination or cleaning agents.

Temperature Controller

Turn the Temperature Controller OFF by pressing

and unplug power cord from the electrical outlet.

Wipe the housing with a clean cloth dampened with a mild detergent and water or mild all-purpose
cleaner.

CAUTION: Do not spray cleaning liquids directly onto the Temperature Controller or allow them to
enter the Controller’s vents. Do not use abrasives as these could scratch the housing or the digital
display.

Bath Reservoir

Bath Reservoir and Wetted Components — A concentrated bath cleaner (polyclean Bath Cleaner, part
number 004-300050) is available to remove mineral deposits from the stainless steel reservoir and the
Temperature Controller’s wetted parts. The cleaner should be added to the bath reservoir at the
prescribed dosage and circulated at 60°C / 140°F until the scale is removed.

CAUTION: Do not use steel wool to clean your Circulator’s bath reservoir.

External Surfaces — Only mild detergents and water or an approved cleaner should be used on the top
deck and other external surfaces of your Circulator. Do not allow cleaning liquids or sprays to enter the
vents on the rear of the Temperature Controller.

Pump Impeller

In the unlikely event that debris becomes lodged in the pump impeller, a soft brush can be used to
remove any lodged particles. If necessary, soak in a solution of distilled water and polyclean Bath Cleaner
to soften before brushing.

warnings for the fluids used as well as those contained in the material safety data sheet.

For optimum temperature stability, the fluid’s viscosity should be 50 centistokes (cSt) or less at its lowest
operating temperature. This permits good fluid circulation and minimizes heating from the pump.

For temperatures from 10°C to 90°C, distilled water is recommended. For temperatures below 10°C, a
mixture of laboratory grade ethylene glycol and water should be used. Do not use deionized water.

The following chart is intended to serve as a guide in selecting a bath fluid for your application. For
optimum temperature stability and low vaporization, be sure to stay within the fluid's normal temperature
range.

You are responsible for proper selection and use of the fluids. Avoid extreme range operation.

Application Notes

At a fluid's low temperature extreme:

• The presence of ice or slush adversely affects temperature stability.

• A viscosity above 10 centistokes adversely affects temperature uniformity.

• A high fluid viscosity and high pump speed adds heat to the fluid being pumped.

At a fluid's temperature above ambient without refrigeration:

• If your set point temperature is less than 15°C above the ambient temperature, the

viscosity of the fluid should be 10 centistokes or less to minimize friction heating of the fluid.

• Heat loss should be encouraged by uncovering the fluid and lowering the pump speed.

At a fluid's high temperature extreme:

• Heat loss from vapor adversely affects temperature stability.

• To prevent the accumulation of vapors inside the room, the reservoir may need to be

placed under a fume hood.

• Use a cover and/or floating hollow balls to help prevent heat and vapor loss.

• Replenish fluid lost from vapor frequently.

Serial Communications Protocol — The Controller uses the following serial communications settings:

Data bits — 8
Parity — None
Stop bits — 1
Flow control — None
Baud rate — Selectable (Controller/PC baud rates must match). 57600 is recommended.

Communications Commands — RS232 commands must be entered using the command only; RS485
commands must be entered using @ and the RS485 address (E.g., @001) followed by the actual
command. All commands must be entered in the exact format shown. Do not send a [LF] (line feed) after
the [CR] (carriage return). Be sure to follow character case exactly.

A response followed by an exclamation point (!) indicates that a command was executed correctly. A
question mark (?) indicates that the Controller could not execute the command (either because it was in
an improper format or the values were outside the allowable range). A response must be received from
the Controller before another command can be sent. All responses are terminated with a single [CR].

IMPORTANT INFORMATION REGARDING SERIAL COMMANDS ENTERED OVER ETHERNET
VIA USER DATAGRAM PROTOCOL (UDP): Only Read commands will be allowed when entering

serial commands over Ethernet unless (1) Ethernet is configured as Unlocked and (2) the proper
password is included as part of the serial command. See Configuring the Ethernet Connection.

Set commands entered over Ethernet must include Pxxx immediately following the serial command.
For example, to change set point, enter the following command: SSiii.iiPxxx [CR] where:

SS = Set set point

iii.ii = set point value

P = password identifier

xxx = password

[CR] = carriage return

time stamp will indicate 0.01 if data logging was enabled after a flash drive or computer was connected
to the USB port. It will show a later time if data logging was enabled before the storage device was
connected. In the example shown above, the flash drive was connected to the USB port 4 minutes after
data logging was enabled.

USB B Setup, Monitoring, and Control

The Advanced Digital Temperature Controller can be monitored and controlled using a personal computer
connected to its USB B port.

Initial Setup

1. Select USB as the COM protocol (see Normal Operation, Selecting a Remote Communication
and Control Protocol).

2. Plug the USB A connector of a USB A to USB B cable into an open USB port on the personal
computer and plug the USB-B connector into the corresponding port on the Temperature
Controller.

3. The computer operating system will automatically detect a new device and ask to install the
drivers for the device. The drivers are located on the Resource Disk that came with your
Temperature Controller.

4. Place the Resource Disk in the computer’s CD drive and install the drivers.

5. Determine the identity of the communications port your computer assigned to the Temperature
Controller.

NOTE: The Advanced Digital Controller’s supports Ethernet communication using User Datagram

Protocol (UDP).

The Advanced Digital Controller may be connected directly to a laptop or desktop computer via its
Ethernet connection or indirectly via your facility’s wired or wireless network. Either type of connection
enables you to control and/or monitor the operation of your circulating bath using User Datagram Protocol
(UDP). The Controller’s active serial communications commands are used to retrieve and/or change
operational information.

Direct Computer to Controller Configuration

NOTE: If your computer is already connected to a wired network, you will not be able to directly

connect it to your circulating bath’s Temperature Controller.

1. Open the utility that displays your computer’s available network connections.

2. Select an available wired connection.

3. Enter the following properties for the selected connection:

A. Internet protocol: TCP/IP
B. IP address: any three sets of identical numbers (e.g., 111.111.111) followed by a single

digit (e.g., 111.111.111.5).

C. Subnet mask: 255.255.255.0

4. Enter the IP address into your Controller as outlined in Fixed IP Addressing, below. Please note

that the first three series of numbers in IP address on the Controller must match those entered in
