Installation
The 403U and 405U drives are suitable for singl e ph ase main s ele ctr icity supplies only.
The pumps are supplied with a mains cable fitted with a moulded plug. 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 - W hit e; Earth - Green.
403U and 405U drives with product codes ending in "U" (UK mains cable) and "E" (European mains cable) accept
230V, 50/60Hz only, whereas pumps with product codes ending in "A" (American mains cable) accept 110V,
50/60Hz single phase mains voltage.

Troubleshooting
Should the pump fail to operate, make the following checks to determine whether or not servicing is required.
Check that mains supply is available at t he pu mp.
Check the mains supply fuse.
Check that the pump is not stalled by incorrect fitting of tubing.
Manual operation
Change the set speed by pres sing the or key. Pump speed is displayed in percentage of maximum s peed.
The 403U has a speed control ratio of 20:1. This will give a minimum speed of 0.5rpm for the 10rpm 403U drive
and 2.5rpm for the 50rpm 403U. The 405U has a sp eed control ratio of 10:1. This will give a minimum speed of
20rpm for the 200rpm 405U drive.

Remote control
The 403U and 405U dr ives can be controlled remotely via 0-10V or 4-20 mA anal ogue signals. 400AC1, 400AC2,
400AC3 and 400AC4 remote control cables with a 15-pin D-sub connector are available from your local WatsonMarlow dealer. Wiring diagrams for each control cable are shown at the bottom of this section.

The keypad speed control setting sets the range of the remote speed signal, and it can be adjusted during remote
control use. (If the manual speed is set 50 %, only 50% of maximum speed will be achiev a ble at 10V or 20mA). It
is advisable to set the speed to 99.9 % f or fu ll an alogue speed range control.

With a remote direction switch connected and the remote cw/stop/ccw switch set to cw or
ccw, you cannot switch direction manually. However, you can stop the pump manually
using the keypad which is designed to be used as an "emergency stop". The remote
cw/stop/ccw switch needs to be set to stop to release the "emergency stop".

Care and maintenance
The only scheduled maintenance of the pump unit is to replace the motor brushes and to replace them when
necessary, understanding that motor brushes are not covered by the two year warranty. It is recommended that this
work be carried out by a Wats on-Marlo w ser vicing ag ent. Th e life of the b rus hes dep ends on the duty of the pu mp but
is expected to be at least 2500 hours at maximum speed for the 403U and 5000 hours for the 405U.
If the pump requires cleaning use a mild solution of detergent in water after removing the pumphead. Do not use
strong solvents.
