THE 3000PLUS PANEL METER
Incorporating Daytronic’s 5D Series Signal Condition-
er Modules
, the 3000PLUS Panel Meter is a field-scal-
able indicator featuring operator-programmable signal
processing and PC/PLC communications. With a
durable front panel and secure screw terminals for all
power and I/O connections, this mechanically and elec-
trically rugged instrument is ideal for pump, motor,
hydraulic, and other high-noise monitoring applications.
Accepting the fully conditioned output of any standard
plug-in 5D module*, the 3000PLUS maintains signal
integrity to deliver accurately scaled analog output,
while sampling all data at 16-bit resolution. The data dis-
play provides selectable digital filtering for even greater
readout stability.
The operator can easily select any of three separate
output channels for display, as explained in Section 1.D:
• the meter’s standard ±5-VDC scaled output
(
Channel 1), representing measured engineering
units (after calibration)
• the “auxiliary” DAC output (Channel 2), which
serves to monitor and process Channel 1, and to
generate Channel 3
• the “scaled voltage” output (Channel 3), which is
continuously proportional to the reading of the auxil-
iary output (Channel 2). Channel 3 may be set to a
full scale of either ±5 or ±10 VDC, and is available
from the rear of the 3000PLUS as both voltage and
4-20 mA output (see Section 2.D).**
The auxiliary analog output (Channel 2) is used for
• HI/OK/LO limit monitoring with selectable hystere-
sis windows, front-panel annunciation, and relay out-
puts for local process control (see Section 5.E for
full details)
• high-speed positive or negative peak capture with
TTL-level “have peak” output, selectable “backout”
and “peak defeat” thresholds, and user-adjustable
leak rate (Section 5.B)
• a signal hold to allow captured peaks and other
values to be transferred to computer for processing
(Section 5.C)
• automatic application of a desired tare offset (Sec-
tion 5.D)
Separate logic inputs provide external control of peak
capture, signal hold, tare application, and the release of
latched limit violations.
As explained in Sections 3 and 4 of this manual, you
can quickly set up the 3000PLUS either via the simple
front-panel button menu or via the configuration soft-
ware supplied with the unit. Operator-entered ranges,
filters, calibration points, and other setup parameters
are always specific to the installed 5D Series condition-
er.
A standard RS232 interface operating at a fixed rate of
19.2K baud allows connection of an external PC for
instrument configuration and on-line monitoring. It may
also be used for direct communication of simple ASCII
mnemonic commands both for run-time reconfiguration
and for interrogation of current data and setup values.
Employing the run-time version of Microsoft
®
Access
2000, the
3KP CONFIGURATOR software supplied
with the Model 3000PLUS makes short work of meter
setup. Communicating via the RS232 link, the Configu-
rator lets you define, store, edit, download, upload, and
manage any number of “configurations” for your
3000PLUS. As explained in Section 4, “off-line” configu-
rations can be easily created and downloaded, or you
can use the “Live Output Window” to view and modify
the present configuration of the connected 3000PLUS
instrument on a purely run-time basis.
The Configurator also lets you perform selected run-
time operations, including
• both “absolute” and two-point (deadweight) calibra-
tion
• viewing any of the meter’s three “live” analog out-
puts and adjusting it as desired
• applying a signal hold command
• releasing any and all latched limits
• sending standard mnemonic commands to the
meter
THE MODEL 5D64 DC
VOLTAGE CONDITIONER MODULE
Delivering a high-level filtered analog output of ±5 VDC,
the Model 5D64 is a wide-range general-purpose
instrument for conditioning the signal received from a
DC-to-DC LVDT, potentiometer-type sensor, Hall-Effect
device, photocell, current shunt,
or other external DC
voltage source. The DC input may be either differential
(floating) or grounded (single-ended).
The Model 5D64’s differential inputs and generous
common-mode range eliminate ground-coupling errors
normally associated with off-ground signal sources. A

1.A GENERAL DESCRIPTION AND SPECIFICATIONS
* “V” and “S” models may not be used with the 3000PLUS.
** The ±5-VDC output of the installed 5D64 conditioner (prior to
A/D conversion) is also available from the rear of the meter.
