Connections
1. The microprocessor board has a se-
lector for voltage or current operations.
Figure 2-10 shows switch orientation.
In voltage mode, output is 0-10 V. In
the current mode, the output can be
configured from the SETUP menu to
be 0-20 mA or 4-20 mA.

2. The analog output and relay outputs
are programmed by the user as
needed. The analog output is typically
sent to recording equipment such as
needed. The analog output is typically
sent to recording equipment such as
chart recorders. Relay outputs are typi-
cally sent to annunciators.

4. All wiring must conform to local and
national codes.
5. Connect the analog output and relay
outputs as shown in Figure 2-12.

HEATER POWER SUPPLY INSTALLATION
a. Mechanical
Installation
The outline drawing of the heater power
supply enclosure in Figure 2-13 shows
mounting centers and clearances. The
NEMA 4X enclosure is designed to be
mounted on a wall or bulkhead. The heater
power supply should be installed no further
than 150 feet (45 m) from the probe. The
heater power supply must be located in a
location free from significant ambient tem-
perature changes and electrical noise. Am-
bient temperature must be between -20°
and 140°F (-30° and 60°C).
