When connected to a controlling device, the inputs can be programmed to perform
the following ICS-900 functions:
•
Switch the injection valve position (load/inject)
•
Set the conductivity to zero (autozero)
•
Turn the pump on and off
C.1 Connecting a TTL or Relay
1. Locate the 12-position
connector plug (P/N 923686)
(see
Figure C-2 ) in the ICS-900
Ship Kit (P/N 067768).
2. Obtain a twisted pair of wires
(P/N 043598) from the Ship Kit
of the Dionex instrument that
will be connected to the
ICS-900.
3. Follow these basic steps to
connect the TTL or relays.
a. For each TTL or relay to be used, connect an active wire (red) and a
ground wire (black) to the 12-position connector plug at the appropriate
pin locations. Refer to
Figure C-1 or the label on the ICS-900 rear panel
for the connector pin assignments.
To attach a wire to the plug, strip the end of the wire (if necessary), insert
it into the plug, and use a screwdriver to tighten the locking screw.
Multiple ground wires can be attached to a single TTL input/output
ground pin.
b. Plug the connector into the 12-pin connector on the ICS-900 rear panel.
c. Connect the wires from the ICS-900 connector plug to the TTL or relay
connector pins on the other module(s). Additional connector plugs are
provided with other Dionex modules.
When attaching wires to the connector plug, be careful not to allow
stray strands of wire to short to the adjoining position on the
connector.
