DO keep delivery and suction tubes as short as possible and follow the straightest route. Use bends of large
radius. Any valves in the pipeline must not restrict the flow.
DO use suction and delivery pipes equal to or larger than the bore of the tube in the pumphead. When pumping
viscous fluids use pipe runs with a bore several times larger than the pump tube.
DO fit long lengths of pump tube and move fresh tube through the pumphead at regular times. This will reduce
tube failure.
DO keep the track and rollers clean.

Analogue signals and remote controlAnalogue signals and remote control
Analogue signals and remote controlAnalogue signals and remote control
Analogue signals and remote control
Pump starting and direction may be remotely controlled by switches, and speed by analogue signals, connected to
the 25-way D connector at the rear of the pump. The analogue interface will accept either 0-10 VDC or 4-20 mA
signals.
To select analogue operation press key until “ana” is showing in the display. The AUTO icon will show on the
display.
Pump speed will increase with an increasing analogue signal. The pump will be stopped at 0V or 4mA. This
interface is pre-calibrated at the factory and may not be altered. If the analogue signal is too high the pump will
display an error message “E21”(Over signal).
The remote stop/start and direction switches work with both manual and analogue control modes. But the analogue
signals will work only with analogue control mode.
Never apply mains voltage to the 25-way D socket. Apply the correct signals to the pins
shown below. Limit signals to the maximum values shown. Do not apply voltage across
other pins. Permanent damage, not covered by warranty, may result.
Speed control
Analogue voltage signal pins 4 and 14 Analogue current signal pins 4 and 14 link 3 and 15
Input impedance 200 kohms Input impedance 250 ohms
Maximum voltage signal 10V Maximum current signal 20mA
Stop/Start
A remote stop/start switch may be connected between pins 7 and 17 of the 25 pin socket. Or a TTL compatible
logic signal may be applied to pin 7. (Low 0V High 5V maximum. Ground to pin 17). This is available in
manual and analogue operation.

To invert the stop/start action of the switch or TTL compatible signal:
• Turn off the mains power switch at the rear of the pump.
• Hold down the and keys. Turn on the mains power switch.
• The display will show the present signal setting; RS for factory default response or IRS for inverted signal
response.
• Press the or key to reverse the present setting.
• Press key to set the signal response and return to manual operation.
Signal response Switch TTL compatible signals
Factory Default (RS) Open = start pump High 5V = start pump
Inverted(IRS) Open = stop pump High 5V = stop pump
Manual operation with a remote stop/start switch
If you invert the operation of the remote stop/start switch you must connect a wire link from pin 7 to 17 to be
able to start the pump from the keypad. This diagram shows the combined effects of the remote switch and the
pump keypad.
If is pressed the remote stop/start switch will have no effect.
Direction
Connect remote direction switch between pins 5 and 17. Also link pins 6 and 18 to enable remote direction control.
The and keys on the pump will be disabled. Open switch for clockwise rotation, close switch for counter-
clockwise rotation. With no connection, the pump will default to clockwise rotation. Or a TTL compatible logic
signal may be applied to pin 5. (Ground to pin 17). High (5V maximum) for clockwise rotation. Low (0V) for
counter-clockwise rotation.
You cannot invert the remote direction signal.

Speed
A remote potentiometer may be connected to control the pump speed. Use a potentiometer of between 1K
and 10KOhms, with a minimum power of 0.25W. Connect the potentiometer as shown. Set the pump to
analogue control. Do not apply another voltage or current control signal while using a remote potentiometer.
RS232 serial linkRS232 serial link
RS232 serial linkRS232 serial link
RS232 serial link
The RS232 interface will give basic pump control by serial link to the 9-way D connector at the rear of the
pump. An interface kit is available from Watson-Marlow which includes Pumpnet 2, a DOS compatible
control program, and connection cable.
To select RS232 serial control, repeat key press until “dig” is showing in the display. Any analogue signals,
or remote control inputs, applied to the 25-way D connector will be ignored.
The 323Du version of the serial interface provides a direct link to a single pump. The pump has no unique
address but the software requires a pump identification of 1.
Use only twin shielded RS232 cables for interconnections.
Never apply mains voltage to the 9-way D connector. Only RS232 signals may be applied
to pins 2,3,5 and 8. Do not apply voltage across other pins. Permanent damage, not
covered by warranty, may result.

313D and 314D pumpheads
The 313D pumphead has three rollers and is designed to provide higher flow rates. The 314D pumphead has four
rollers to provide greater pumping precision with less pulsation in the flow. Both designs are available for 1.6mm
and 2.4mm wall tubes.
New tubing can be loaded easily into the flip top design. The top closes with a “clamp and stretch” action to locate
the tube in the correct position and with the correct tension.
Standard and extension pumpheads are bayonet mounted. This ensures easy cleaning and fast set up.
Tube selection
The chemical compatibility list published in the Watson-Marlow catalogue and web site is only a guide. If in doubt
request a tube sample card for immersion trials.

Tube loadingube loading
ube loadingube loading
ube loading
Switch off the pump before tube loading. Lift the “flip top” track until fully open.
Set the tube clamps to the correct tube size. The track must be
fully open. Align the scale on both sides of the pumphead.
If the tube is dirty, or there is a high suction lift, the tube clamps may
need a smaller setting to secure the tube.

• Select enough tube length for the curve of the pump track.
Slide the tube into the open pumphead. The tube must not be twisted or stretched against the rollers.
• Ensure the tubing locates in the centre of the tube clamps. Carefully lower the track. Check that the tube is not
crushed in the clamps or over stretched.
When using Marprene tubing
Re-tension new tube after the first 30 minutes of running. Stop the pump. Release the flip top. Allow the tube to re-
settle naturally across the rollers. Re-clamp the tube. Re-start the pump. This will correct the normal stretching
that occurs with new Marprene tube. The correct tension is essential for good tube life.

Each pumphead offers 5 pumping channels, and the manifold tubing is preloaded in removable cassettes.
The 314MC pumphead has four rollers and is designed to provide higher flow rates. The 318MC pumphead
has eight rollers for higher pumping precision with less pulsation.
Each cassette will accept any one of nineteen tube sizes available. Adjacent cassettes may contain different
types or size of tubing.
New tube loads easily in the cassette design. Cassettes locate quickly with a single cam lever action that also
controls roller pressure against the tube.
Extension pumpheads may be added up to 10 channels. All are bayonet mounted for easy cleaning and fast set up.
Tube selection
The chemical compatibility list published in the Watson-Marlow catalogue or web site is only a guide. If in doubt
request a tube sample card for immersion trials.

The 323 drives require a mounting plate to attach a 314MC or 318MC pumphead.
Engage the pumphead drive slot with the end of the pump drive shaft. Continue to align the pumphead
until the bayonet engages with the mounting plate. Turn the pumphead until it locks into an upright
position.
RemovalRemoval

Removal
Push the locking lever back and turn the pumphead anti-clockwise until it is free from the mounting plate.
314MC and 318MC pumpheads must not run at speeds greater than 110rpm.
