2.6 External Control Settings
The easyFLOW-VS has the ability to be controlled by an external device. For example, it can be
connected to a miniCHEM pH controller to control the pH of an industrial process. Using the
correct cable connections and jumper settings, the easyFLOW-VS can be set up to be externally
controlled in the any of the following ways…
1. Simple On and Off switching, operating at the speed setting of Dose Rate control.
2. Variable speed operation, proportional to a 4-20 mA input, where 4mA is stopped and 20mA is
full speed.
3. Variable speed operation, proportional to a 0 – 1V DC input, where 0V is stopped and 1V is
full speed.
4. Either of the variable speed external control settings above can be set up with a manual
override to switch the unit off.
Refer to the following diagram when setting up the External Control connections…
Notes
To access the circuit board’s settings, remove
the four screws at the corners of the front panel
and remove the lid. Please use caution, to avoid
damaging any connecting cables.
In the table below, “Switch” under H4 refers to
an external switch to turn the easyFLOW-VS on
and off. This can be in the form of standard
on/off switch or the relay contacts of a process
control unit.
“Link” under H4 refers to linking the two
terminals with a piece of wire.
When removing jumpers, we recommend that
you fit it to one of the pins. This way, it will not
be lost if the jumper is to be replaced at a later
time.
“n/c” means “No Connection” at that terminal.

2.7 Setting the Pump Speed to 50%
Operators who wish to use the easyFLOW-VS at a low speed may find it difficult to set the desired
speed accurately with the Dose Rate control. A “50%” jumper fitting is provided for these users. To
select “50%” speed operation…
1. Remove the front panel and locate the jumper settings, as per the instructions in section 2.6.
2. Set jumper J3 to On to select 50% speed operation.
3. If the unit is returned to the factory default Off setting at a later time, we recommend that you
fit it to one of the pins. This way, it will not be lost if the jumper is to be replaced at a later time.

Section 3 – Operating Instructions
12
Section 3. – Operating Instructions
3.1 Manual Operation
The easyFLOW-VS is set for manual operation by default.
1. Plug the AC/DC Adaptor into a suitable mains power outlet and switch on.
2. Set the Dose Rate control to the desired pump speed.
3.2 External On / Off Control Operation
1. Connect the External Control cable as detailed in section 2.6. The cable gland should be
finger-tight to ensure a good waterproof seal. Use only round cable, as flat or figure-8 cables
will not seal correctly in the gland.
2. Plug the AC/DC Adaptor into a suitable mains power outlet and switch on. Note that the
External Control LED lights up to indicate that the easyFLOW-VS is under external control.
3. Set the Dose Rate control to the desired pump speed.
3.3 External 4-20 mA or 0-1 V Control Operation
1. Connect the External Control cable as detailed in section 2.6. The cable gland should be
finger-tight to ensure a good waterproof seal. Use only round cable, as flat or figure-8 cables
will not seal correctly in the gland.
2. Plug the AC/DC Adaptor into a suitable mains power outlet and switch on. Note that the
External Control LED lights up to indicate that the easyFLOW-VS is under external control.
3. It is not necessary to set the Dose Rate control as the pump speed is determined by the 4-20
mA or 0–1 V signal.
3.4 External 4-20 mA or 0-1 V Control Operation with Manual OFF Override
1. Connect the External Control cable as detailed in section 2.6. The cable gland should be
finger-tight to ensure a good waterproof seal. A single round 4 core cable should be used to
ensure a waterproof seal at the gland.
2. Plug the AC/DC Adaptor into a suitable mains power outlet and switch on. Note that the
External Control LED lights up to indicate that the easyFLOW-VS is under external control.
3. It is not necessary to set the Dose Rate control as the pump speed is determined by the 4-20
mA or 0 – 1 V signal.
3.5 Adjusting the Zero point when using 4-20 mA External Control
Every pump motor has a different point at which it starts and stops. This zero point also varies with
time. For this reason, a Zero adjustment has been provided when using the 4-20 mA External
Control…
1. Set the device that is producing the 4-20mA signal to 4 mA. For a TPS controller, such as a
miniCHEM or proCHEM this can be done by switching the unit to its Limit setting mode and
adjusting the Limit to Zero. This will cause the unit to output 4 mA.
2. Adjust the RV1 control until the pump is running, then adjust it back until the pump just stops.
The Zero point has now been correctly set.

Section 4. – Peristaltic Dosing Pumps
4.1 Lubricating the Pump Tubing
The easyFLOW-VS is shipped with the correct lubrication on the peristaltic pump tubing. This
lubrication should be re-applied every year. Suitable Silicon lubricant is available from TPS in a
3mL syringe (part no 130103).
To lubricate the pump tubing…
1. Remove the pump tubing, as per the details in section 4.2, below.
2. Smear a small quantity of Silicon grease all around the tube. A thin film is all that is required.
DO NOT use petroleum based oil or lubricants, as these will cause the Santoprene
rubber to perish. Use only Silicon based lubricant.
4.2 Replacing the Pump Tubing
Replace the Pump Tubing if it gets worn, begins to leak, or pumping volume is reduced. The Pump
Tubing may be replaced every year as a precautionary measure.
To remove the old Pump Tube…
1
IMPORTANT
Place the pump suction
tubing into a bucket of
fresh water. Prime the
pump with water by
switching on at full
speed to 3 minutes. This
ensures that there is no
dangerous chemical in
the tube when it is
disconnected.
2 3 4
Switch off the power and
disconnect the power
cord.
Remove the Input and
Output tubing from the
compression fittings.
This is simply a reversal
of the procedure
detailed in section 2.4.
Remove the see-
through protector plate
on the front of the pump.
5
Turn the roller holder so that the rollers are in a horizontal line. Pull the left
hand side compression fitting from its seat. Begin turning the roller holder
clockwise, so that the roller holder acts as a lever which pulls the pump tube
out as it turns. After approximately 3/4 of a turn, the right hand side
compression fitting can be pulled out.
The old pump tube has now been removed.

Section 4 – Peristaltic Dosing Pumps

To fit a new Pump Tube…
1
Turn the roller holder so
that the rollers are in a
horizontal line. Push the
left hand side
compression fitting into
its seat, round side
facing in. Begin turning
the roller holder
clockwise, so that the
roller holder acts as a
lever which pulls the
pump tube in as it turns.
After approximately 3/4
of a turn, the right hand
side compression fitting
can be pushed in, round
facing in.
The new pump tube has
now been fitted.
2 3 4
Replace the see-through
protector plate on the
front of the pump. This
is essential to protect
the rollers and tube from
dirt and moisture.
Re-fit the Input and
Output tubing to the
compression fittings.
See the procedure
detailed in section 2.4.
The power to the
easyFLOW-VS can
now be re-connected
and switched on.
Warning : Use only a genuine replacement Tube supplied by TPS. Use of other tubing materials,
sizes or lengths may place undue stress on the rollers, causing them to wear
prematurely. This type of wear is not covered by warranty.
