Comments
This instrument is not unique in its content of ESD (electrostatic discharge) sensitive
components. Most modern electronic designs contain components that utilize metal oxide
technology (NMOS, CMOS, etc.). Experience has proven that even small amounts of static
electricity can damage or destroy these devices. Damaged components, even though they
appear to function properly, may exhibit early failure.

WIRING
WIRING CONNECTIONS
AC / DC CONNECTIONS:
NOTE: Connect power only after other connec-
tions are finished. Do not touch the live AC power
terminals. The unit has been designed with an
isolated AC input, therefore polarity is not a con-
cern for the AC power. The chassis is plastic,
thereforeearthgroundis notused. ForDCopera-
tion, connect +DC to terminal 10 and -DC to
terminal 3.
This Product complies with requirements of the
EuropeanCommunityDirective89/336/EEC[Elec-
tromagnetic Compatibility]. However, electrical
noiseorintenseelectromagneticfieldsinthevicin-
ity of the unit may disturb the microprocessor.
Usersshouldexercisecareandshouldtakeproper
precautions to avoid microprocessor disturbance.
Four common sources of noise are:
1) AC power line noise- The input power lines
should not be common to power lines for motors,
pumps, contactors, etc. If the unit cannot be con-
nected to an electrically clean power source, an
inductive load suppressing device (MOV as
GE#V130LA1 or Resistor Capacitor as Paktron#
.2uf/220ohm @ 400V) can beinstalled. Although
locating the suppressor across the AC supply at
the unit should help, best results are obtained by
connectingthe suppressoracross theleads ofthe
"load" at the device causing the spikes.
2)Inputlinenoise-Thenoiseiscarriedontheinput
and DC ground lines. Make sure the input wires
arenotrunintotheunitinabundlewithpowerinput
lines. Werecommendusingshieldedcable. Con-
necttheshieldtoDCgroundoftheunitand"earth"
at one point in the circuit preferably at the DC
ground terminal of the unit.
3) Output lines- The unit has two open collector
outputs and two optional relay outputs. When
these outputs are used to run external relays or
solenoids, spikes can be generated upon activa-
tion. Thisnoisecanspreadthroughtheinstrument
causingoperatingproblems. IfthesourceisaD.C.
operateddevice,ageneralpurposediode(IN4004)
placed across the solenoid prevents electrical
noise spikes. Connect the cathode (banded side)
to the more positive side of the coil. If the source
isanA.C.operateddevice,useaResistorCapaci-
tor or MOV across the coil.
4)24 VDC outputsupply- Noisecan be generated
on the 24 VDC output supply if it is used to drive
inductive loads or if the current draw exceeds
50mA. Insurethatallinductiveloadshaveadiode
(such as IN4004) across the coil and that the
current does not exceed 50mA.

The open collector and relay outputs trigger when the
total or rate (assignable; see programming step 2)
equals the corresponding Preset (A or B).
Whentheoutputsareassignedtothe"total",theopera-
torcanassignadurationoftime (.01to599.99sec.)that
theoutputwillremainenergized. If0.00isassigned,the
outputwilllatchuntilreset. IfoutputAissetataduration
(other than 0.00), the totalizer will autorecycle when
Preset A is reached. At this time, output B will de-
energize (if it was energized). Preset A is the final
preset and should be set higher than Preset B, when
both outputs are assigned to the total. If output A is set
at a duration other than 0.00 and Preset A is set less
than Preset B, Preset B will be ignored (provided that
theyare bothassignedto total). Thetotalizerwillnever
autorecycle at Preset B.
Whentheoutputsareassignedtothe"rate",theoutputs
can be assigned a hysteresis (alarm range). The
hysteresis is the number of units below the preset that
theoutputwillremainenergized. EXAMPLE:Presetset
@ 100; Hysteresis set @ 10. The output will energize
when the rate equals 100 and de-energize when the
rate falls below 90 (10 below Preset).
NOTE: Iftheinputscalingisinverted,thecontroloutput

This section applies to units which have the
serialcommunicationsinterfaceoption. Upto
99 units can be linked together. Unit status
can be accessed and many menu items can
be entered through the serial port. Data is
transmittedatselectedbaud rates using stan-
dardeight bitASCIIcharactersandone“stop”
bit. Theunitdoesnotcheckortransmitaparity

UNIT I.D. (DEVICE #)
Each unit in the hookup must be assigned a
unitnumberfrom 1 to99. Thiscanbeentered
through the front panel (see step 5 of the
programmingsection). If “00”isassigned,the
unit can not be brought on line through the
serialport. Theunitswillremaininan“off”high
impedance state until addressed by the as-
signedunitnumber. Onceaunitisaddressed,
do not address another unit until the data has
been sent and any data requested has been
transmitted back.
BAUD RATE
The baud rate is the speed at which data is
transmitted, expressed in bits per second.
Baud rates of 300, 1200, 2400 or 9600 are
available. Select the desired baud rate from
the menu. (see step 5 of the programming
section).
PRINT LIST
The serial interface card is equipped with a
strobe line. When the strobe line is activated
a user selectable set of data (print list) is
transmitted. This transmission can be sent to
acomputerorprinter. Theprintlistconsistsof
