Electrical Connections
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’.
