SMU RS-485 Model
(See Figure 5)
1) Power Input
- The SMU is designed to accept either 115VAC or
230VAC (factory set). Verify the intended voltage supply is com-
patible with the voltage configuration indicated on the electron-
ics 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) RS-485 Network
- The SMU interconnection of the network
is made with a 2-conductor shielded cable (such as Belden
9322). All SMUs are interconnected in a daisy-chain, multi-
drop configuration. Order of connection is not important (i.e.
the operator interface can be placed between SMUs if
necessary). A communication network such as this operates
most effectively when the interconnection has only two ends.
"T"s should be avoided whenever possible.
Observe polarity when making the communication intercon-
nection (+D and -D). Attach the cable shield in the terminal
identified as "SHD". Do not run communication cable in the
same conduit as power.
3) Lock-Out
- The "lock-out" 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 lock-out!
If a "lock-out" signal is provided while a
measurement cycle is already in process, the plumb bob will
immediately return to the start/socket position. The lock-out
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 lock-out circuit
is "dry", meaning that the voltage must be provided for opera-
tion (i.e. just making a switch connection between "Vhi" and
"COM" will not lock out the SMU operation). Refer to the
Specifications section for electrical ratings.
4) Relay Output
- The "Relay Output" is a configurable isolat-
ed SPDT switch. See Figure 11 & 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 ratings.
