3-2 I nstallation
3-1-1.'Wiring Precautions.( I ) Be sure to terminate all cable connections in
solderless crimp-on lugs.
Q) Each status and voltage input must be as per
SLBC specifications. Note the limits on conduc-
tor resistance, voltage drop in conductors, and
voltage (high/low) levels. (Refer to the SLBC
General Specification at the back of ' thismanual.)
(3) The fail and digital outputs are transistor contact
signals (isolated from power suppli'and otherinternal circuitry). When connecting externaldevices, pay attention to the following: (See
Figure 3-l-3.)O Observe correct polarity of status output ter-
minals.O Most status outputs share a common nega-
tive terminal.O When connecting a relay or other such
inductive device, connect a surge absorber(protective diode Figure 3- 1-3., CR circuit,,etc.) in parallel with the load.
O Note that status outputs cannot be connecteddirectly to an AC circuit. Use a relay toswitch an AC circuit.
o Do not connect any load which exceeds the
contact rating. (Max. 30V DC' 200 mA).(4) Use shielded twisted-pair SCCD cable for com-
munication lines (tern.Y 's 17., l8).

41. Alarm Func-tions.
Alarm functions that are peculiar to SLBC are
detection of missing pulse input and detection ofleakage
Figure 4-1-l shows the relationship between the
alarm functions and batch sequence.(l) Detection of loss of pulse input.
If between the time flow should have reached
high limit setting and pre-batch'end the pro-
cess variable flow input signal level remains
below O.7 \Vo of span, the input signal is con-
sidered to be missing: the ALM lamp lights and
the alarm output contact opens.
(2) Detection of leakage.
The leakage during the period between batch
end and resetting is rneasured. If the leakage
equals or exceeds a preset value (auxiliary data
setting)., the ALM lamp lights and the alarm out-
put contact opens.
"Reset" resets the detected leakage value, but
leakage detection continues until "Starl". ,

values of auxiliary data items such as function
specifying data. K factors and other computationaland control constants must be decided and input,
and these values should also be writtbn on the data
label (see note ) .
When preparing the data label, refer to TlI84A3-I IE "YewSeries BCS Explanation of auxili-ary data, and data label/work sheet writing pro-

5-4-3. Automatic Control.The procedure for setting controller integral time
and proportional band is explained below. Ingeneral. if a small change in the controller outputcauses a large fluctuation in the process variable
value, the width of the proportional band must be
increased (the gain must be reduced) to. assure
statility. ln the converse case, the proportional band
must be narrowed.For a process'which responds quickly to a change
in the controller output, the integral time constant
must be srnall. For a process having a long recovery
time, the integral time constant must be large.
Set the integral time and proportional band as
follows:( I ) Set the control mode to M , and tbe integral
time to 9999 sgc. Set the proportional band to asufficiently large value., and then set the controlmode to tr
Q) To obtain the optimum value for the propor-
tional band, perform the following operations:
Decrease the value of proportional band from its
initial large value in steps (for example, from
100'X, to 50'X, to 2A"1,) - Take a sufficiently long
time for each step, so that the state of control
can be observed fully. Continue this operation
un til the control loop begins cycling. (Cycling
means periodic (cyclic) oscillation of the process
variable pointer around the set point, and this
phenomenon is caused by setting the propor-
tional band narrower (setting the gain higher)
than the optintunt value for the process. )
ll'cycling occurs, increuse the width of'the pro-
portional band until the nleter indication stabil-
izes.(3 ) Decrease the integral time in steps. u p to a
point. decreasing the integral time improves the
speed of response of the controller. but if the
integral time is shortened too far. cycling is
caused due to dead tinte in the process. In such
a case. increase the integral time gradually until
the cycling disappears.

The control ntode of the controller can be

Input Processing FunctionsProcess variable and' auxiliary flow inputs may be
either voltage or pulse signals, compensation input may
be either a voltage or RTD signal'
Input Cutoff : Analcg flow input signals less than A.787o
of span, and pulse flow input signals less than A'24H2,
Pulse Output: Output pulse rate may be scaled by a
factor K'. K' (Kl , Ke ) are S-dieit fixed point num-
bers, of maximum value 29999.Pulse Output ON Tkne: Selectable one of 20,33, 50
or 100 ms or duty cycle of Savo (for YewSeries
BCS Instruments: up to ten may be connected in
parallei with outPut).Analog OutPut: I to 5 V DC.
Totalizer FunctionsFive totalizers are built in three 6-digit batch
totalizers and two 8-digit (cumulative) totalizers:o Batch flow totalizer (process variable only).o Batch flow totalizel (process variable, with compensa-
tion computation).o Batch flow totalizer (process variable, with auxiliary
flow signal added to or subtracted from it, and
compensation computation).o Cumulative flow totalizer (process variable, with
auxiliary floy signal added to or subtracted from it).o Cumulative flow totalizer (process variable, with
auxiliary flow signal aclded to or subtracted from it,
and compensation computation)
Batch totalizer is reset after end of each batch by
reset input signal or front panei reset pushbutton.
Cumulative flow totalizer r filEY be reset maqually by
entering other data for totalizer value '
Data Display and Data Setting FunctionsData Display:
upper display is batch loader setting, 6 digits.
Lower display is selectable data, 6 digits.
Selectable data (displayed in lower dispiay) may be
major data itern or auxiliary data item:
Major Data ltem: Displayed data type is indicated by
lamp ne xt to data itegr iabei on froni panel' Value
of batch flow totalizer ( for process variable with
auxiliary flow signal added to or subtractec from
it, and compensation computation), batch loader
set value, instantaneous flow high linrit and instan-
' taneous flow may be disPlaYed'
Auxiliary Data ltem: Displayed data type is indicared
by code displayed in upper display' Auxiliary data
hrcludes the other four totalizer values, pre-batch
alarm settirtg, progrem set parameters and control
parameters. A table of data that may be displayed
is on the instntment side Panel'lnstantaneous Flow Display: 5-segment bar graph'
Data Setting:Displayed Data Seiection: Selected by push buttons-
One switch (on side panel) changes from major data
displaY to auxiliary data disPiaY'
Data setting: uses push button switches. Data setting
may be inhibited (disabied) by an inhibit/enable
switch on the side Panel
point number).Totalizer Scale Factors: Scaler for pulse signal input
(constant K number of pulses for every flow unit
totalized). Totalizer scaie factor for analog signal
input. K (Kr , Kz) are S-rjigit fixed point numbers,
of maximum value 29999 -
Auxiiiary Flow-signal Processing: Auxiliary flow signal
can be added to or subtracted from process variable
signal. Range of analog output ( to PI algorithm,
display and repeater) is bdjustabte'
compensation computation: can compensate the
process variable and auxiliary flow signals for liquid
density changes with temperature. other types of
compensation are also possible (see below).

General Compensation Computations:
computation Format: vo = v(c + 0.5), c ranges from
. 0 to I - its value corresponds to the compensation
input signal; a voltage in the range I to 5 V DC
Flow Signal RePeater FunctionOutputs puirr ancl analog signals corresponding to
the process variable input ( the instrument can also
add or subtract an auxiliary flow signal input in this
case. the span of analog output (to PI algorithm, dispiay
and repeater) is acljustable).

SLBC ModesThe S LBC Batch Controller offers
modes:o Batch loader (combination of batch
PI controller) or
the following
set station and
c PI controller (standalone controller, or master con-troller in a blending control system).
o SPC or DDC modes are also possible.
Batch Loader: One SLBC mode is batch loader (batchset station plus PI controller). (See batch sequencein table, and flow setpoint program in figure below).Program is started by start status inpu t or startpushbutton on front panel.
PI Controller: Another S LBC mode is PI controller(standalone controller, or master controller in a
blending control system demand pulse ogtput,using flow signal repeater, and master pacing inputprovided). -
Emergency Stop/Ristart (see figure): Provided for batchloader or PI con troller modes (see above) usingstopistart status inputs. Ramp change in outputbetween high and low flow limits, step change inoutput between low flow limit and zero.
Master Pacing Input: Changes (ONIOFF or OFF/ON)cause the output to rampl between high and low flowlimits. Useful when SLBC is used as a blending masteror used in a blending batch loader system (the SLBCcan provide a demand pulse signal to a slave con-
' troller such as the SLCC Blending Controller).
