Display range selection is made using binary numbers to represent the
full scale operating range for the receiver. The RANGE SELECTION table,
below, provides the proper switch settings for the ranges available on each
receiver. Range selection is made using switches C1 to C4. The 4-20mA
output signal is proportional to the selected range.

shown in FACTORY SETTINGS OF RANGE AND SETPOINTS table, above,
and can be changed by using the configuration switches identified
in the DIP SWITCH FUNCTIONS chart. The Warning setpoint is set us-
ing switches A2 to A8 and the Alarm setpoint is set using switches
B2 to B8. A binary number is used to select setpoints as a percent of
operating range.
