SMU Analog(4-20mA) Model
(See Figure 6)
1) Power Input
- The SMU is designed to accept either 115VAC
or 230VAC (factory set). Verify the intended voltage supply is
compatible with the voltage configuration indicated on the
electronics and the external nameplate. Connect power as
shown to "L1" and "N" being sure to observe polarity. The
connector can be unplugged from the bottom PCB for your
wiring convenience.
2) Sound
- The "sound" input starts the SMU measurement by
an external contact closure (switch). The external switch
must provide voltage to either "Vhi" (98-265VAC/DC) or
"Vlo" (20-55VAC/DC) with respect to the "com" terminal. The
SMU sound circuit is "dry" meaning that voltage must be pro-
vided to the circuit (i.e. just making a switch connection
between "Vhi" and "com" will not start the SMU). It is permis-
sible to start all SMUs with a single switch (parallel wiring to
each SMU). Refer to Specifications section for electrical ratings.
3) Relay Output
- The "Relay Output" is a configurable isolat-
ed SPDT switch. See Figure 12 for description of configurable
functions. The SMU "relay output" circuit is "dry". Direct
connection of voltage from COM & N/O or COM & N/C termi-
nals will damage the output, a voltage with a series load must
be wired to the "relay output". The relay's normal state is
energized, so if power to the SMU is interrupted the relay will
de-energize to provide the same state as an alarm condition.
When the orange LED is on the relay is energized. Refer to
the Specifications section of this manual for electrical rating.

4) 4-20mA
- The "4-20mA" output is an isolated, self-powered
current loop. The term "self-powered" refers to the ability of
the SMU to create the 4-20mA signal without needing an
external power supply. The "self-powered" current loop can
drive up to 500 ohms of loop resistance before degradation of
the current output begins. The 4 and 20mA limits (relating to
material levels) are established through the configuration as
explained in the Setup section of this manual. Each SMU 4-
20mA output signal must be kept independent from each
other. Observe polarity when connecting to the "+" and "-" ter-
minals. Refer to Specifications section for electrical ratings.
5) Lock Out -
The "lockout" input can prohibit the SMU from
making a measurement cycle (i.e. protection against taking
measurement during a filling cycle).
This is not to be used as
a safety lockout!
If a "lockout" signal is provided while a
measurement cycle is already in process, the plumb bob will
immediately return to the start/socket position. The lockout
function is activated when a voltage is provided to either "Vhi"
(98-265VAC/DC) or "Vlo" (20-55VAC/DC) with respect to the
"COM" terminal. The SMU lockout circuit is "dry" meaning
that the voltage must be provided for operation (i.e. just
making a switch connection between "Vhi" and "COM" will not
lockout the SMU operation). Refer to the Specifications
section of this manual for electrical ratings.
