Connecting the Power Cord

Make sure that the ON/OFF switch is in the OFF (down) position. Connect the power cord to the power socket at the rear of the instrument and then to the power supply source. When the ON/OFF switch is put to the ON position, the instrument initializes; the valve motor rotates the spindle and stops with the valve set to the outlet position. The piston motor raises the piston to the upper position.

Connecting the Keypad

Switch off the 402 Dilutor-Dispenser, before con- necting or disconnecting the keypad.

Grip the connector, at the end of the coiled connec- tion cable, so that you squeeze the clip between your thumb and index finger. Then, plug the connector into the socket on the rear panel labeled ‘KEYPAD’ (see figure). You must grip the connector in the same way when disconnecting the keypad.

The coiled connecting cable enables you to use the keypad beside the 402 (as in Chapter 2), or even at some distance away from it. However, you can also install the keypad on top of the 402; to do this you should insert the tab on the rear support of the keypad into the slot on top of the 402 and then gently push the tab in as far as it will go.

Connecting the Probe

Grip the connector, at the end of the black connec- tion cable, between your thumb and index finger. Then plug the connector into the socket on the rear panel labeled ‘PROBE’.
