3.1 Preparing to Operate the
Module
This chapter explains how to operate the Series 356 Micro-Ion Plus Module.
The module can be operated by providing power to the module as
described in the Installation chapter and using the analog output signal, or
the RS-485 interface, or by using the optional display.
Before putting the module into operation, you must perform the following
procedures:
1. Install the module in accordance with the instructions on pages 13–23.
2. Connect Pin 1 (Micro-Ion Gauge ON/OFF) of the User Interface
Connector to ground (Pin 5), or it must be controlled by the user’s
process control.
3. Develop a logic diagram of the process control function.
4. Develop a diagram detailing the Analog Output connections.
5. Develop a diagram of the connections to the RS-485, I/O status, and
control lines of the 15-pin User Interface connector.
6. Develop a circuit schematic that specifies exactly how each piece of
system hardware will connect to the module relays.
7. Attach a copy of the process control circuit diagram to this manual for
future reference and troubleshooting.
8. For units with the RS-485 interface, set the module address, baud rate,
and parity as instructed on pages 41 – 42. All RS-485 command
instructions are listed in the section titled
RS-485 Operation and
Commands beginning on page 40.
