Information for returning pumps

Equipment which has been contaminated with, or exposed to, body fluids, toxic chemicals or any other substance hazardous to
health must be decontaminated before it is returned to Watson-Marlow or its distributor.

A certificate included at the rear of these operating instructions, or signed statement, must be attached to the outside of the
shipping carton.

This certificate is required even if the pump is unused. If the pump has been used, the fluids that have been in contact with the
pump and the cleaning procedure must be specified along with a statement that the equipment has been decontaminated.

Safety

In the interests of safety, this pump and the tubing selected should only be used by competent, suitably trained personnel after
they have read and understood this manual, and considered any hazard involved.

Any person who is involved in the installation or maintenance of this equipment should be fully competent to carry out the work. In
the UK this person should also be familiar with the Health and Safety at Work Act 1974.

There are dangerous voltages (at mains potential) inside the pump. If access is required, isolate
the pump from the mains before removing the cover.

Recommended operating procedures

DO keep delivery and suction lines as short as possible using a minimum number of swept bends.
DO use suction and delivery pipelines with a bore equal to or larger than the bore of the tube fitted in the pumphead. When

pumping viscous fluids, the losses caused by increased friction can be overcome by using pipe runs with a cross sectional
area several times greater than the pumping element.

DO run at a slow speed when pumping viscous fluids. When using the 501RL pumphead, a 4.8 or 6.4mm bore tube with a

1.6mm wall will give best results. Tube smaller than this will generate a high-friction pressure loss, so reducing the flow. Tube
2

with a larger bore will not have sufficient strength to restitute. Flooded suction will enhance pumping performance in all cases,
particularly for materials of a viscous nature. Silicone and Marprene tubing is available with a 2.4mm wall thickness for speeds
up to 200rpm. (The rotor will require re-setting to a roller/track gap of 3.8mm.)

DO fit an extra length of pump tube in the system to enable tube transfer. This will extend tube life and minimise the downtime
of the pumping circuit.

DO keep the track and rollers clean.
The self-priming nature of peristaltic pumps means valves are not required. Any valves fitted must cause no restriction to flow in

the pumping circuit.
When using Marprene tubing , after the first 30 minutes of running, re-tension the tube in the pumphead by releasing the tube

clamp on the delivery side a little and pulling the tube tight. This is to counteract the normal stretching that occurs with Marprene
which can go unnoticed and result in poor tube life.

Tube selection The chemical compatibility list published in the Watson-Marlow catalogue is only a guide. If in doubt about the
compatibility of a tube material and the duty fluid, request a tube sample card for immersion trials.

Installation

The 505S/RL is suitable for single phase mains electricity supplies only.
To ensure correct lubrication of the gearbox the pump should be run only while its feet are standing on a horizontal surface. The

pump should be positioned to allow a free flow of air around it.

• Set the voltage selector to either 120V for 100-120V 50/60Hz supplies or 240V for 220-240V 50/60Hz supplies.

A mains cable fitted with a moulded plug is supplied with the pump. The wires are colour coded in accordance with the
following code:

• 220-240V: Live- Brown; Neutral - Blue; Earth - Green/Yellow.

• 100-120V: Live - Black; Neutral - White; Earth - Green.

Reduced voltage operation

In areas where voltage is below that specified above, modifications can be made to the pump unit to allow operation under the
following minimum voltage levels:

• 180V when using the 220-240V setting.

• 90V when using the 100-120V setting.

The modification requires the connector J18 on the Control PCB to be reversed. To locate the terminal, isolate the mains
supply then remove the pump cover. State A shows the standard voltage setting, whilst State B shows the reduced voltage
setting. Any damage caused to the pump in the process of carrying out this modification will not be covered by warranty.

Control PCB State A State B

Refer servicing to qualified personnel only.

Troubleshooting

Should the pump fail to operate, make the following checks to determine whether or not servicing is required.

• Check that the power switch is on.

• Check the mains supply is available at the pump.

• Check the voltage selector switch is in the correct position.

• Check the fuse in the mains socket.

• Check that the pump is not stalled by incorrect fitting of tubing.

3

Manual operation

• Switch power on (drive rear panel).

• Change the set speed by pressing the Ù or Ú key. The 505S speed control ratio is 110:1. This will give a minimum speed of

2rpm for the 220rpm drive and 0.5 rpm for the 55rpm drive.

• Change direction by pressing the CW/CCW key. Check the flashing CW/CCW symbol for actual direction setting. (CW :

clockwise CCW : counterclockwise).

• Select the maximum speed: press the Ù key and the Max key together. Select the minimum speed: press the Ú key and the

Max key together.

• The keypad has a locking facility to avoid resetting or tampering. If the pump is stopped, press Stop until the padlock symbol

illuminates. If the pump is running, press Start until the padlock symbol illuminates. All keys will be disabled except for Start
and Stop. Press these keys until the padlock symbol extinguishes to unlock the keypad.

• The pump can be set to automatically restart in its operating state set prior to interruption, or set so that after power is

reconnected the pump will remain stopped. To invoke the Auto-restart facility switch off power to the pump at the mains
supply. Press the Start key down when the mains supply is switched back on until the ! symbol illuminates. Now press Start
to start the pump. This facility can be cancelled by turning the mains supply off and then pressing the Stop key whilst turning
the mains supply back on. The ! symbol will not be illuminated.

• Press Start to start the pump. Press Stop to stop the pump.

Error messages

If a fault condition is detected in the drive unit it will stop, all keys will be disabled, and the display will flash:

Er1 Tachometer fault
Er2 Over temperature error
Er3 EEPROM error
Er4 EEPROM read error
Er5 EEPROM write error
Er6 EEPROM exhausted error. There is a maximum number of times the EEPROM can be written to. If Er6 is displayed,

however, the EEPROM must be replaced.

Er9 RAM corruption error

Care and maintenance

The only scheduled maintenance of the 505S is to inspect the motor brushes and to replace them before their length is less
than 6mm (1/4"). The life of the brushes will depend on the duty of the pump, which is expected to be at least 10,000 hours at
maximum speed. When the pump needs cleaning, remove the pumphead and use a mild solution of detergent in water. Do not
use strong solvents.

If the gearbox is rebuilt you should use 15 ml of the recommended lubricant, which is RD105, this is a SAE 30 mineral oil loaded
with molybdenum disulphide to form a soft fluid grease.

501RL Pumphead

The 501RL pumphead has two spring-loaded working rollers, which automatically compensate for minor variations in tubing
wall thickness, giving extended tube life. The 501RL is set during manufacture to accept tubing with wall thicknesses of between

1.6mm and 2.0mm, and internal diameters of up to 8.0mm. It is equipped with a "tool lockable" guard for increased safety. This

should be locked shut whilst the pump is in use.

4

The pumphead can be run clockwise for extended tube life, or anti-clockwise to operate against higher pressures.

Flow rates

Flow rates for the 505S were obtained using silicone tubing with the pumphead rotating clockwise, pumping water at 20C with
zero suction and delivery pressures. For critical applications determine flow rates under operating conditions.

Installation

Fit the track in any one of three orientations, over the drive shaft and locating boss. Secure the track with the locating screw.
Ensure the drive shaft is degreased before locating the rotor onto the shaft via the split collet. Tighten the rotor screw to a torque
of 3Nm to prevent the collet slipping during operation.

To reposition the track, swing out the crank handle to expose the rotor retaining screw. Turn the screw anticlockwise one turn to
release the collet, and withdraw the rotor from the shaft. Loosen the track locating screw, and pull the track clear. Rotate the
track to its new position and tighten the track locating screw. Use this method of removal and fitting in case cleaning is required.

Tube loading

Isolate pump from mains supply. Unlock and open the hinged guard and swing out the rotor crank handle until it locks into
position. Select the length of tubing required, noting that approximately 240mm is required for the track systems.

Fit one end of the tubing into one of the spring loaded clamps, and then, whilst rotating the rotor with the crank handle, feed the
tubing between the rollers and the track, aligning it within the rotor tube guides. The tubing must lie naturally against the track
and must not be twisted or stretched.

Fit the other end of the tubing into the second spring loaded clamp, ensuring that the tubing is not slack in the pumphead, since
this can reduce tube life.

Close the crank handle and shut and lock the guard.
After the pump has been started, open the delivery clamp for a short time, so that the tube can find its natural length.
The 501RL pumphead is fitted with four-position tube clamps, to accommodate various tube diameters, which can be adjusted

by pushing in or pulling out the bars at the top of the upper clamp and the bottom of the lower clamp. Set the clamps so that the
minimum necessary pressure is applied to the tubing.

Roller adjustment

The 501RL has a factory set gap of 2.6mm between the rollers and the track and is suitable for tubing having wall thicknesses of
between 1.6 and 2.0mm. Adjustment of the gap will be required if tubing having a wall thickness of less than 1.6mm is required.
There is an adjusting screw on each of the two roller arms, and each of these screws will require adjustment. The correct gap is
twice the wall thickness less twenty percent. Correct adjustment is important: over occlusion will reduce tube life; under
occlusion will reduce pumping efficiency.

To change the gap setting, turn each adjusting screw clockwise to increase the gap, or anticlockwise to decrease the gap. A full
turn changes the gap by 0.8mm.To restore the original settings of 2.6mm, turn the adjusting screws until both rollers are just

5

touching the track, then tighten each screw by three and a quarter turns. The 501RL2 has a factory set gap of 3.8mm between
the wall and the track and is suitable for tubing having wall thickness of between 2.1 and 2.5mm.

Check moving parts of the rotor from time to time for freedom of movement. Lubricate pivot points and rollers occasionally with
Teflon lubricating oil.

Specific drive performance details such as loaded drive speed variation against mains supply voltage fluctuation and drive
stability from a cold start to normal operating temperature are available on request. For further information please contact
