All wiring must conform to local and national codes. Refer to Figure 2-3 and
use the following procedure to connect the first oxygen transmitter. Repeat
the procedure for each remaining oxygen transmitter.
1. Run the line voltage through the bulkhead fitting on the bottom of the
IMPS 4000 marked LINE IN. Connect the line voltage to the J24
terminal. The power supply automatically adjusts to the input voltage.
Tighten the cord grips to provide strain relief.
2. When connecting an Oxymitter O
I/O wires for each oxygen transmitter through a bulkhead fitting on the
bottom of the IMPS 4000 marked SIGNAL IN. Dedicate one fitting for
each oxygen transmitter. Connect the oxygen transmitter logic I/O wires
as shown in Figure 2-3.
3. When connecting an X-STREAM O
signal wires from connector J3 of the Xi I/O board through a bulkhead
fitting on the bottom of the IMPS 4000 marked SIGNAL IN. Dedicate
one fitting for each oxygen transmitter. Connect the oxygen transmitter
handshake signal wires as shown in Figure 2-3.
4. To set up the IMPS 4000 to initiate a calibration from a remote location,
run the remote contact input wires through the SIGNAL IN bulkhead
fitting. Connect the remote contact input wires as shown in Figure 2-3.
5. Status relay connections are available on the IMPS 4000 PC board to
signal when the oxygen transmitter is in or out of calibration and to
indicate calibration gas status. Status relays can be connected to either
indicator lights or a computer interface. Relay contacts are capable of
handling up to 5 to 30 V, 1.5 A per point, 3.0 A total per common
maximum power source. Cabling requirement is 1000 ft (303 m)
maximum. Make the status relay switch connections as shown in
Figure 2-3.
