functions on each terminal block. The output and alarm connections should be installed by a qualified
electrician.
Route the cables to the terminal blocks through the pass-through port, labeled Control, on the left side of the
Analyzer. Remove the pass-through cap. Secure the PVC conduit connector ("strain relief" hub) and washer to
the conduit and the Analyzer in the normal manner. Wire should be 22-18 AWG, rated to 300 Volts. Strip lengths
should be 8-9 mm (0.33 in). Install the ferrite (from the Accessories Kit) on the I/O cable, as shown in
page 87.
To attach the output connections, first remove the terminal block from the I/O board by firmly grasping
the terminal block and pulling it straight out from the board. Make a note of the orientation of the terminal block
before removing. Completely loosen the screw for each pin you are connecting, insert the wire, tighten the
screw, and then gently pull on each connection to make sure the connection is secure. Gently reinsert the
terminal block into the board socket.
Starting from the front of the Analyzer, the terminal blocks are as follows
• TB1 Analog Outputs — The maximum 4-20 mA load is 600 ohms. Analog outputs 1-5 are allocated for
transferring data for streams 1-5. Analog 6 indicates which stream is currently active during the analyses
of multi-streams (or if applicable, a single-stream).
• TB2 Binary Input (Analysis Start/Stop)
• TB3 Alarm Outputs (Alarms 3 and 4, System Fault Alarm, and the Binary Analysis Complete Signal) —
The maximum load for these ports is 30 VDC at 1.0 A or if using double-insulated wiring the maximum
load is 125 VAC at 0.5 A.
• TB4 Alarm Outputs (Alarms 1 and 2) — The maximum load for these ports is 30 VDC at 1.0 A or if using
double-insulated wiring the maximum load is 125 VAC at 0.5 A.
