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 ins tallation or maintenance of this equipment should be f ully c ompetent to c arry out
the work. In the UK this person should also be familiar with the Health and Safety at Work Act 1974.

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 fit an ex tra length of pump tube in the s ystem to enable tube tr ansfer. This will extend tube lif e 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.

Tube selection T he chemical compatibility list published in the W atson-Marlow c atalogue is only a guide. If in doubt
about the compatibility of a tube material with the duty fluid, request a tube sample card for immersion trials.

Installation

The 101F/R and 101U/R are 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.

•

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.

•

101F/R operation

Turn power switch to on (I) position to start pump.

•

Turn power switch to off (0) position to stop pump.

•

101U/R Manual operation

Set the front panel Auto/Man switch to Man.

•

Turn power switch to on (I) position to start pump.

•

Turn power switch to off (0) position to stop pump.

•

Change pumping direction using the CW/CCW switch on the front panel, and s et the pum p speed using the digital

•

potentiometer which is calibrated in percentage of maximum speed.

To prime the pump at maximum speed press the Max key.

•

It is not nec essary to dis connect the pr ocess signal f rom the r ear panel 15-pin D connector or adjust the calibration
potentiometers if returning to manual control after the pump has been in automatic operation.

101U/R Automatic operation

Set the Auto/Manual switch to Auto.

•

For all auto and remote control operations, the drive is supplied with a 15 pin D connector.

Never apply mains voltage across any pins on the 15D socket. Up to 30V may be applied across
pins 2 and 10, but no voltage should be applied across other pins except where specified.
Permanent damage not covered by warranty may result in both instances.

The pump is controllable by an analogue pr ocess signal of up to 30V or 32m A. The pump will provide an increasing

flow rate for rising control signal (non-inverted response ) or an inc reasing flow rate for falling control signal (inverted
response ).

•

Signal offset is the process signal level which has to be reached in order for the pump rotor to start rotating.

•

Signal range is the change in process signal level necessary to produce the required change in pump rotor speed.

For example, when using a 4mA to 20mA process signal:

Pump response Signal offset Signal range

Non-Inverted 4mA 16mA
Inverted 20mA 16mA

For voltage m odes, a s table variable DC voltage s ource can be us ed in c onjunction with a DC voltmeter, (maximum
30V DC). Polarity set for a non-inverted response. Reverse polarity for an inverted response.

Voltage signal

Input impedance 220 kohms

Response Range V Offset V Pin 10 Pin 2

Non-inverted 5 to 30 0 to 30 -+
Inverted 5 to 30 0 to 30 +-

For current modes, the s ame DC s ource can be us ed in c onjunction with a DC m illiampere meter, (maximum 32mA).
Polarity set for a non-inverted response. Reverse polarity for an inverted response.

Input impedance 250 ohms

101U/R Calibration procedure

Turn the signal offset potentiometer (20 turn potentiometer) clockwise until the slider traverse limit is reached and is

•

signified by a clicking noise. Now tur n the potentiom eter ten tur ns antic lockwise. Repeat f or the s ignal r ange
potentiometer. This ensures correct potentiometer set-up for calibration.

Set the process signal offset.

•

Turn the signal offset potentiometer clockwise to set the pump shaft speed to the desired minimum.

•

Set the process signal at its upper range limit (not exceeding 30V or 32mA).

•

Turn the s ignal range potentiometer (marked "Range" on bac k panel) clockwise to s et the drive shaft speed to the

•

desired maximum.

If the process signal or pump speed are set above their designated maximums the pum p will be over loaded which is
signified by the signal overload indicator illuminating. This is an indication of the limiting control and speed levels of the
drive. Reset to operate within these levels.

Repeat the procedure until pump response coincides exactly with the process signal.

•

Remote auto manual switch and TTL option

If the front panel s witch is to be us ed for changing between "manual" and "auto", link pins 6 and 13 in the 15- pin Dee
connector. If a remote switch is to be used, ensure that no link is present between pins 6 and 13, and w ire the s witch
between pins 7 and 13 of the 15-pin Dee connector. Close switch for auto-control.

Alternatively, the r emote auto- manual s witch m ay be r eplaced by a 0/5V T TL c ompatible s ignal applied to pin 7
(reference pin 13). 0V = manual (Man), +5V = auto (Auto).

Remote operation

Stop/start

Connect r emote s witch betw een pins 8 and 13 of the 15 pin c onnector. A T TL c ompatible input (low 0V, High 5V)
maybe applied to pin 8. Low input stops the pump, high input runs the pump. With no connection, the pump will default
to running.
