Analog Range Key
The Series 2000 control unit allows you to direct process readings to
either of the two analog output ports on the rear of the control unit. If
you have the combustibles option, you can also have process readings
directed to the two extra analog output ports that are activated if you
have the combustibles option. Analog output parameters are defined
using the
Analog Range Key menu.
See the “Select an Analog Output Port” section in this chapter for help
on how to select an analog output port. All functions in this chapter are
directed to a specific analog output port.
The Analog Range key (Figure 4-5) of this chapter provides help on how
to do the following:
y
Define what information should be sent to the analog output port
during a calibration. Decide whether to hold the output at the last
process reading taken before the start of calibration or track the
calibration readings (Set Track/Hold).
y
Define analog output range as 0-to-20 mA or 4-to-20 mA (Set Current
Mode).
