2.3 Attaching the accessories
2.3.1 Electrical connection to the 732 IC Detector
In order to allow remote operation of the pump via the 732 IC Detector,
connection 15 15 of the 754 Dialysis Unit must be connected to the
"Remote" connection of the 732 IC Detector by means of the
6.2143.200 cable as per Fig. 4. The switch 22 on the front
of the 754 Dialysis Unit must additionally be set to "ON" to permit re-
mote operation.
If you wish to connect a second, additional unit (e.g. 752, 753, 754) to
the remote interface of the 732 IC Detector, connect the Dialysis Unit
754 using the optionally available 6.2143.220 cable instead of the
6.2143.200 cable.
