DESCRIPTION & SPECIFICATIONS
DESCRIPTION:
The 913 DRT (Dual Rate Totalizer) is a dual 5 digit Ratemeter 6
digit Totalizer in a 1/8 DIN package. User selects 1 of 6 displays to
show A,B or C rate and A,B or C total. Inputs A and B have
separate scaling to read in engineering units.
A 4-20mA (0-20mA) output of the C rate or total is optional.
The user can press the VIEW button to see 6 separate items
total A, total B, total C, rate A, rate B, rate C. Negative values are
displayed with a negative symbol ( - 12345 ). For the C value, the
user can choose from the following combination of A&B inputs:
TOTAL; with a choice of A+B or A-B; RATIO with choice of
A÷B(x100) to show percent of A to B quantity or A÷[A+B(x100)] to
show percent of A to total quantity.
Two independent presets are standard. User selects whether out-
put A is activated by total or rate value of input A or selected C.
Output B can be activated by total or rate value of input B or
selected C. Outputs activated by A or B total can be set to latch or
autorecycle with an adjustable output duration from 00.1 to 99.9
sec. For rate, ratio, or C total outputs pull in when value is equal or
above the preset and drop out when value is below the preset
minus the selected 0 to 999 hysteresis.

RESET:
Front Panel: Resets displayed value and control output
Remote: 4-30 VDC negative edge resets all counters,
"A" counter or "B" counter (user selectable).
K FACTOR/SCALING
The 913 DRT has two separate K-Factors that are used to convert
the input pulses to engineering units. The 5 digit K-Factor dividers,
with decimal keyed into any position, allow easy direct entry of any
K-Factor from 0.0001 to 99999. Separate factors may be entered
for the 2 separate input channels.
CONTROL OUTPUTS:
Relays:
2 each N.O. Relay; 10 Amps120/240 VAC or 28 VDC.
(N.C. relay contacts and NPN transistor output
available with solder jumpers. Transistor output is
internally pulled up to 10 VDC through relay coil, sinks
from 10 VDC to .5 V @ 100 mA)
Analog Output:
An optional 4-20mA (0-20mA) output is available for
the 913 DRT. The output can be programmed
to track rate or total of the C display. This feature is available
by adding suffix A to the part number. Connections are
via a 2 terminal pluggable screw connector.
Programming is accomplished by using the front panel
in conjunction with rear dip switches.
Accuracy: 50uA worst case.
Compliance Voltage: 3 to 30 VDC non inductive.
RS232/RS422SERIAL INTERFACE
If the serial interface option is supplied, up to 99 units can be linked
together. (The terminal addressing the unit must be capable of
driving all loads in the loop.) Unit status and new set points can be
communicated by serial communication. Mode changes, however,
must always be made on the front panel. Data is transmitted at
selected baud rates using standard seven bit ASCII characters and
parity with two additional bits of “Start” and “Stop” to make up the
standard ten bit character.
Data is received and transmitted over standard EIA RS232 or
RS422 levels. Each 10 bit character is made up of a start bit, 7 bit
ASCII code, parity bit and stop bit. Unit number, baud rate and
parity are entered in the “Program Setting” set up mode and remain
in memory even if power is off.
Note that the input impedance of RS232 is 3K or 7K Ohm worst
case. The terminal addressing the unit must be capable of driving
all loads in the loop. RS422 input impedance is much higher and
there is usually no problem driving 25 units. Unit serial transmit line
remains in a high impedance “OFF” state until addressed.
PRESETS
Two control outputs are provided. To set relay values, press “menu”
button until “Relay” appears on the display, the Aand B outputs can
be assigned to theA,B or C displays. A5 digit value can be entered
for both presets and the decimal point location is the same as the
counter. The outputs can be set to energize from 0.1 to 99.9
seconds or latch (0.0). If a value other than 0.0 is entered, the
counters will auto reset at the preset (for A&B counters).

DECODING PART NUMBER
LOCKOUT
Unauthorized front panel changes can be prevented by entering a
user selected 5 digit code. The front panel can be completely
locked out or the presets can remain accessible.
RATEMETER
Accurate to 4 1/2 digits (±1 display digit). The ratemeter uses 1/tau
with 8 digit math, can sample from 2 to 24 seconds maximum, and
auto-range up to 5 digits of significant information. In the “RPS”
mode, the ratemeter displays in units per second, and in the
“scale” mode, units per hour or per minute. The unit will display the
rate of the A&B Inputs.
COUNTER
The two 6-digit counters can count at 10Khz speed. Each has a
seporate 5-digit dividing scale factor. The counters advance on the
positive edge of each pulse. Besides being able to step through the
total and rate values of A & B inputs, the user can see a selected
combination of total or rate of A+B, A-B, A÷BX100 (percent of A to
B), A÷A+BX100 (percent of A to total). A negative display will be
veiwed as a 5 digit display with a negative symbol ( - 12345 ).

HOW TO MOUNT THE UNIT
The unit is designed to be mounted with a gasket providing a water tight seal. Two mounting brackets are provided to
secure the unit to the panel. A panel less than .1" may distort if the clamps are screwed too tightly.
Slide the body of the unit through the rubber gasket. Insert the unit into the panel. As shown in "FIG. A", slide the brackets
up the groove to press against the back of the panel. Insert screws into rear of brackets and tighten them evenly and
alternately. Do not over tighten! A normal level of torque is required. Maximum torque should be 3" pounds.
This product is designed to be panel mounted and is NEMA 4 rated if proper mounting procedures are followed and the
required and supplied hardware is correctly used.
If the panel in which the unit is mounted is less than .125 of an inch thick, the possibility exists that there will be some
flexing. Should this flexing occur, the resulting deformation of the panel could cause a loss of the water tight seal. In case
this should occur, the use of silicone or other sealant would be recommended.
This product is designed to the NEMA 4 rated. However, the fact that we are unable to control either the location in which
the device is installed or the actual installation itself requires that the company's liability shall extend only to the repair or
replacement of a defective product.
We are prepared to offer additional assistance in those special situations where normal mounting methods do not seem to
satisfy the customers needs. This assistance may be obtained by calling the factory and asking for Application Engineer-
ing.

WIRING THE 913 DRT
The rear terminal contains 12 screw terminals for connecting #14 to #28 gauge wire.
The unit is controlled by a microprocessor and, therefore, an electrically "noisy" environment could cause operating
problems. The input power line should not be common to power lines for motors, pumps, contactors, etc.
The unit is designed to be immune from line or RF voltage interference. In some environments voltage spikes of over 100
volts, even 1000 volts, can occur. When common to a power line driving motors voltage fluctuations can be extreme and
rapid. Lines driving DC or AC solenoids, relays, or actuators can also cause problems.
Four sources of noise can occur:
1) AC power line noise - If the unit cannot be connected to a clean power source, an inductive load suppressing device
(MOV as GE # V130LA1 or Resistor Capacitor as Paktron # .2 uf/220 ohm @ 400V) can be installed. Although locating
the suppressor across the AC supply at the unit should help, best results are obtained by connecting the suppressor
across the leads of the "load" at the device causing the spike.
2) Input line noise -The noise is carried on the input and D.C. ground lines. Make sure the input wires are never run into
the unit in a bundle with power input lines. Also, keep these input lines isolated from inductive lines from devices
drawing heavy loads. If there is a possibility of electrical noise, we recommend using shielded cable, with the shield
being hooked to the D.C. ground terminal on the instrument, and to "earth" at one point in the circuit, preferably at the
D.C. ground terminal of the unit.
3) Output lines - The unit has two relay outputs. When these outputs are used to run external relays or solenoids, spikes
can be generated upon activation. This noise can spread through the instrument causing operating problems. If the
source is a D.C. operated device, a general purpose diode (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 is an A.C. operated
device, use a MOV or Resistor Capacitor across the coil.
4) 12 VDC output supply - Noise can be generated on the 12 VDC output supply if it is used to drive inductive loads or if
the current draw exceeds 50 mA. Insure that all inductive loads have a diode (such as IN4004) across the coil and that
the current does not exceed 50 mA.

CONNECTING AC / DC POWER
NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals! The unit has
been designed with an isolated AC input. Thus, polarity is not a concern for the AC input. The chassis is plastic, therefore
earth ground is not used. For D.C. operation, connect + 12V to pin 7 and - D.C. to pin 8.
CONNECTING SENSOR INPUTS
These diagrams show how to hook typical input sensors to the unit. The unit supplies an unregulated 12 Volt (50mA)
output to power these sensors (Pin 7).
A valid pulse is one which makes a transition from the off-state (0 to 1V) to the on-state (4 to 30V): a positive going edge.
The input impedance is 10K Ohms to ground. The unit can be programmed from the front panel for slow switch closure
inputs up to 40Hz (select "Lo CPS"), or solid state switches (select "hi CPS") up to 9.99KHz. No rear terminal jumpers are
required. Use PNP (sourcing) type pulsers.

CALCULATING SCALE FACTORS
There are two separate dividing scale factors, one for input "A" and one for input "B". The factor to enter is the number of
pulses per the desired unit of measurement. The factor ranges from 0.0001 to 99999. The factor is the same for rate and
count. Because the "units per second", "minute", or "hour" are field programmable from the keypad, scale factor calcula-
tions for the ratemeter are easy. Here are some examples:
SCALING FACTOR EXAMPLES:
UNIT COUNTING: You pick up a notch on a paper roll (1 pulse per shaft revolution). Each revolution equals 3 feet. To
find the number of pulses per foot, simply divide "1 pulse" by "3 feet" (1÷3 = .3333).
Solution - One foot equals 0.3333 pulses, enter this as the scale factor and the display will read in
feet.
RATE: A conveyor carrying bottles must be controlled for bottle speed. For each revolution of the front roller, three bottles
travel by. Thus, one revolution equals 3 bottles. A wheel with seven spokes is mounted on the roller. The user
can't sense bottles because they are traveling through a washer, so a sensor is placed at the roller, sensing seven
pulse per revolution of the shaft, which equals 3 bottles per revolution.
To calculate the scale factor (7 ppr ÷3 bottles) = 2.3333 scale divider. Set rate per second, minute or hour as
desired.
FLOW IN LITERS:
A flow meter is generating 52.6 pulses per gallon. The desired readout is in liters. Since there are 3.785 liters per
gallon, divide 52.6 by 3.785 to find the number of pulses per liter (52.6 ÷3.785 = 13.897).
Enter 13.789 as the scale factor so the display will read in liters.
CUT TO LENGTH:
An aluminum sheeting plant has a cut to length application to customer specification. A 100 pulse per revolution
encoder with a 12" wheel is used to sense. The travel of aluminum sheets is in 0.1 inches. Thus, after 100 pulses,
you want 12.0 to appear on the display. Note that decimal point is for display only. Factor must be calculated to
show all desired units of measure. Thus, 100 ÷120 (total desired units of measure) = 0.8333. Enter 0.8333 as your
scale factor. Set “dummy”decimal point location to 0.0 under Program Count section.
FLOW BOILER OR MOTOR “A-B”:
Fuel usage of a boiler can be monitored using the “A-B”option. Separate factors can be entered for Factors “A”
and “B”, but the time base must be the same for rate.

OUTPUT WIRING
The following diagrams detail the connection of the relay and analog output options. Each relay consist of a form A contact
(Normally Open). NPN transistor or Normally Closed contacts are available with solder jumpers (see Jumper Options).
SOLENOID (Single Stage)
Use Relay A (pins 1 & 2) for single stage preset. When the count or rate (selectable) reaches Preset A, Relay A will
energize. When Relay A closes, current passes through the solenoid for activation. When operating AC solenoids,
we recommend the use of an MOV to reduce inductive kickback (use a diode for DC solenoids).
ANALOG OUTPUT
The analog output can be selected to output 4-20 mA or 0-20 mA and can be selected to track the rate or count of
the C display. Pin 13 supplies 12 to 18V to power the current loop. Pin 14 supplies the current sinking driver.
When connecting a strip chart recorder, make connections as follows:
