INTRODUCTION
The KOBOLD Model MPV pulse input rate/totalizer is a multipurpose, easy-to-use
rate meter and totalizer ideal for flow rate, total, and control applications. It accepts
pulse (40 mVp-p to 8 Vp-p), square wave (0-5 V, 0-12 V, or 0-24 V), open collector,
NPN, PNP, TTL or switch contact signals. Three of the front panel buttons can be
custom-programmed for specific operation.
The basic model includes an isolated 24 VDC transmitter power supply that can be
used to power the input transmitter or other devices. An additional isolated 24 VDC
power supply is included with the 4-20 mA output option.
A fully loaded MPV pulse input rate/totalizer has the following: four SPDT relays,
4-20 mA output, and two 24 VDC power supplies. The MPV’s capabilities may be
enhanced by adding the following external expansion modules: four SPST relays
(creating an eight-relay rate/totalizer), two digital I/O modules with four inputs and four
outputs each, and RS-232, RS-485, and USB communication adapters.
The eight relays can be used for alarm indication or process control applications. The
4-20 mA isolated output, Modbus RTU serial communications, and digital I/O options
make the KOBOLD Model MPV an excellent addition to any system.
A digital input is standard.

INSTALLATION
There is no need to remove the meter from its case to complete
the installation, wiring, and setup of the meter for most
applications. Instructions are provided for setting up a
12/24 VDC powered meter to operate from 12 VDC and for
changing the transmitter power supply to output 5 or 10 VDC
instead of 24 VDC, see page 18.
Unpacking
Remove the meter from box. Inspect the packaging and
contents for damage. Report damages, if any, to the carrier.
If any part is missing or the meter malfunctions, please contact
your supplier or the factory for assistance.
Panel Mounting Instructions
•Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm x
45 mm). Refer to Figure 1 for more details.
• Clearance: allow at least 6.0" (152 mm) behind the panel for wiring.
Recommended minimum panel thickness to maintain Type 4X
rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.
•Remove the two mounting brackets provided with the meter (back-off the two
screws so that there is ¼" (6.4 mm) or less through the bracket. Slide the
bracket toward the front of the case and remove).
• Insert meter into the panel cutout.
• Install mounting brackets and tighten the screws against the panel. To
achieve a proper seal, tighten the mounting bracket screws evenly until
meter is snug to the panel along its short side. DO NOT OVER TIGHTEN, as
the rear of the panel may be damaged.

Serial communications connection is made to an RJ45 connector labeled
M-LINK on Figure 6. For interfacing to the meter, use MPV-Option-B for
RS-485 or MPV-Option-F for USB. The same port is used for interfacing
with all expansion modules (e.g. external relays, digital I/O).
Relay Connections
Relay connections are made to two six-terminal connectors labeled
RELAY1 – RELAY4 in Figure 6. Each relay’s C terminal is common only
to the normally open (NO) and normally closed (NC) contacts of the
corresponding relay. The relays’ C terminals should not be confused with
the COM (common) terminal of the INPUT SIGNAL connector.

Switching Inductive Loads
The use of suppressors (snubbers) is strongly recommended when
switching inductive loads to prevent disrupting the microprocessor’s
operation. The suppressors also prolong the life of the relay contacts.
Suppression can be obtained with resistor-capacitor (RC) networks
assembled by the user or purchased as complete assemblies. Refer to
the following circuits for RC network assembly and installation:
C
C
R
R
Figure 12: AC and DC Loads Protection
Choose R and C as follows:
R: 0.5 to 1 Ω for each volt across the contacts
C: 0.5 to 1 µF for each amp through closed contacts
Notes:
1. Use capacitors rated for 250 VAC.
2. RC networks may affect load release time of solenoid loads. Check
to confirm proper operation.
3.
Install the RC network at the meter's relay screw terminals. An RC
network may also be installed across the load. Experiment for best
results.
Use a diode with a reverse
breakdown voltage two to
three times the circuit
voltage and forward current
at least as large as the load
current.

External Relay & Digital I/O Connections
The relay and digital I/O expansion modules MPV-Option-R & MPVOption-S are connected to the meter using the CAT5 cable provided with
each module. The two RJ45 connectors on the expansion modules are
identical and interchangeable; they are used to connect additional
modules to the system.
Note: The jumper located between the RJ45 connectors of the MPV-
Option-S must be removed on the second digital I/O module in
order for the system to recognize it as module #2.
Do not connect or disconnect the expansion
modules with the power on!
Warning!
More detailed instructions are provided with each
optional expansion module.

Interlock Relay Feature
As the name implies, the interlock relay feature reassigns one, or more,
alarm/control relays for use as interlock relay(s). Interlock contact(s) are
wired to digital input(s) and trigger the interlock relay. This feature is
enabled by configuring the relay, and relative digital input(s) (see page
63). In one example, dry interlock contacts are connected in series to
one digital input which will be used to force on (energize) the assigned
interlock power relay when all interlock contacts are closed (safe). The
interlock relay front panel LED flashes when locked out. The interlock
relay would be wired in-series with the load (N/O contact). See below.

Setting the Decimal Point (dEc pt)
The decimal point may be set with up to five decimal places or with no
decimal point at all. The rate, total, and grand total decimal points are
independent.
Pressing the right arrow moves the decimal point one place to the right
until no decimal point is displayed, then it moves to the leftmost position.
Pressing the up arrow moves the decimal point to the left.
Programming the Rate/Totalizer (prog)
It is very important that one reads the following information before
programming the meter:
•
The meter has been factory calibrated to read input frequency in Hz
(pulses/sec). The calibration equipment is certified to NIST
standards.
• Use the K-Factor menu to match the rate/totalizer with a flowmeter’s
k-factor (pulse/unit of measure).
• Or use the Scale menu to scale the pulse input (pulse/sec) without a
signal source.
• Or use Cal menu to calibrate the rate/totalizer using a signal source.
Program menu contains the following menus:
The
1. K-Factor calibration
2. Scale without a signal source
3. Calibrate with a calibrated signal source
4. Total time base & conversion factor
5. Grand total time base & conversion factor
6. Total reset mode for total & grand total
Note: The Scale, Calibrate, and K-Factor functions are exclusive of each
other. The meter uses the last function programmed. Only one of these
methods can be employed at a time. The Scale and Calibrate functions
can use up to 32 points (default is 2). The number of points should be
set in the Advanced menu under the
Multi-Point Linearization
calibration of the meter, see page 73 for details.
The pulse inputs may be calibrated or scaled to any display value within
the range of the meter.

K-Factor Calibration (Factor)
The meter may be calibrated using the K-Factor function. Most flowmeter
manufacturers provide this information with the device. Enter the
K-Factor (Factor) menu and select the decimal point with highest
resolution possible and program the k-factor value (
i.e. pulses/gal). The
meter will automatically calculate the flow rate using the k-factor and the
time base selected.
Multi-Point Calibration & Scaling
The meter is set up at the factory for 2-point linear calibration. The
number of points for multi-point calibration/scaling is set up in the
Advanced Features menu. Up to 32 linearization points may be selected.
See page 73 for details.
MeterView® Pro Software
The meter can also be programmed using the PC-based MeterView Pro
software available for free download at www.predig.com.
Data logging for one meter at the time is available with MeterView Pro
software. More advanced data acquisition may be accomplished by
using any Modbus RTU compliant software.
In order to program the meter using a computer, the meter must be
connected using a USB, RS-232 or RS-485 serial adapter, see
ORDERING INFORMATION on page 7 for details.
40
KOBOLD Model MPV Pulse Input Rate/Totalizer Operating Instructions
Scaling the Meter (SCALE)
The pulse inputs can be scaled to display the process variable in
engineering units.
A signal source is not needed to scale the meter; simply program the
inputs and corresponding display values.
For instructions on how to program numeric
values see
Setting Numeric
Values, page 35.

KOBOLD Model MPV Pulse Input Rate/Totalizer Operating Instructions
Error Message (Error)
An error message indicates that the calibration or scaling process was not
successful. After the error message is displayed, the meter reverts to
input 2 during calibration or scaling, allowing the appropriate input signal
to be applied or programmed.
The error message might be caused by any of the following conditions:
1. Input signal is not connected to the proper terminals or it is connected
backwards.
2. Minimum input span requirements not maintained.
3. Input 1 signal inadvertently applied to calibrate input 2.
Minimum Input Span
The minimum allowed input span is 1.0 Hz, which is the minimum difference
between input 1 and input 2 signals required to complete the calibration or
scaling of the meter.
Gate Function (Gate)
The gate function is used for displaying slow pulse rates. Using the
programmable gate, the meter is able to display pulse rates as slow as
1 pulse every 999.9 seconds (0.001 Hz). The gate function can also be
used to obtain a steady display reading with a fluctuating input signal.
The gate function (

Hi G).
Gate) is the first option in the Advanced Features
Gate, low gate (Lo G) and high gate
Low Gate (Lo G)
For most applications, low gate setting should be left at 1.0 second.
Increase low gate setting to obtain a steadier rate display. The rate
display will update in accordance with the low gate setting, for example if
low gate is set at 10.0, the display will update every 10 seconds;
changes in rate between updates will not be reflected until next display
update.
High Gate (Hi G)
Set the high gate value to correspond to the highest expected pulse
period (lowest pulse rate). For instance, if the meter must display a rate
when there is 1 pulse coming into the meter every 10 seconds, set the
high gate to 11.0 seconds. When the signal is removed from the meter,
the display will show the last reading for 11 seconds; then it will read
zero.

Time Base, Total Conversion Factor & Total Reset
The time base, total conversion factor, and total reset menus are located
in the
Program menu.
The total and grand total have their own independent settings. This
means that one can be displaying the value in gallons while the other
displays in million gallons, liters, m
3
, etc.
Time Base
The time base is the amount of time over which the rate parameter
should accrue. For example, if the rate was ten and the time base was in
minutes, then the total would increase by ten every one minute.
Total & Grand Total Conversion Factor
The total & grand total conversion factor is the amount by which the rate
is multiplied before it is added to the total or grand total. For Example, if
the rate was ten per second and the total conversion factor was 100, the
total would increase by 1000 every second. This is useful, for instance, if
you want to show rate in gallons and total in thousands of gallons.
Total & Grand Total Reset
The totals can be programmed for manual or automatic reset. In the
automatic reset mode, a programmable time delay is available to reset
the total or grand total after the assigned preset is reached.
Non-Resettable Totalizer
The total and grand total can be password-protected to prevent
unauthorized resets. The grand total can be programmed as a
non-resettable total, see page 66 for details.

Programming Set and Reset Points
High alarm indication: program set point above reset point.
Low alarm indication: program set point below reset point.
The deadband is determined by the difference between set and reset
points. Minimum deadband is one display count. If the set and reset
points are programmed with the same value, the relay will reset one
count below the set point.
Note: Changes are not saved until the reset point has been accepted.
Setting Fail-Safe Operation
In fail-safe mode of operation, the relay coil is energized when the process
variable is within safe limits and the relay coil is de-energized when the
alarm condition exists. The fail-safe operation is set independently for each
relay. Select
on to enable or select off to disable fail-safe operation.
Programming Time Delay
The On and Off time delays may be programmed for each relay between
0 and 999.9 seconds. The relays will transfer only after the condition has
been maintained for the corresponding time delay.
The
On time delay is associated with the set point.
Off time delay is associated with the reset point.

The following graphs show the operation of the time delay function.
When the signal crosses the set point, the On time delay timer starts and
the relay trips when the time delay has elapsed. If the signal drops below
the set point (high alarm) before the time delay has elapsed, the On time

Relay Operation Details
Overview
The relay capabilities of the meter expand its usefulness beyond simple
indication to provide users with alarm and control functions. These
capabilities include front panel alarm status LEDs as well as either 2 or 4
optional internal relays and/or 4 external relays expansion module.
Typical applications include high or low flow alarms and basic batch
control. There are four basic ways the relays can be used:
1. High or Low Alarms with Latching or Non-Latching Relays
2. Simple On/Off Control with 100% Adjustable Deadband
3. Sampling (Based on Time)
4. Alternation Control for up to 8 Relays
Relays Auto Initialization
When power is applied to the meter, the front panel LEDs and alarm
relays will reflect the state of the input to the meter. The following table
indicates how the alarm LEDs and relays will react on power-up based
on the set and reset points:
Alarm #
1 HI 1000 500 499 Off
2 LO 700 900 499 On

Front Panel LEDs
The LEDs on the front panel provide status indication for the following:
The meter is supplied with four alarm points that include front panel
LEDs to indicate alarm conditions. This standard feature is particularly
useful for alarm applications that require visual-only indication. The LEDs
are controlled by the set and reset points programmed by the user.
When the display reaches a set point for a high or low alarm, the
corresponding alarm LED will turn on. When the display returns to the
reset point the LED will go off. The front panel LEDs respond differently
for latching and non-latching relays.
For non-latching relays, the LED is always off during normal condition
and always on during alarm condition, regardless of the state of the relay
(e.g. Relay acknowledged after alarm condition).
For latching relays, the alarm LEDs reflects the status of the relays,
regardless of the alarm condition. The following tables illustrate how the
alarm LEDs function in relation to the relays and the acknowledge button
(Default: F3 key assigned to ACK):
Latching and Non-Latching Relay Operation
The relays can be set up for latching (manual reset) or non-latching
(automatic reset) operation.
Relay terminology for following tables
TerminologyRelay Condition
On Alarm (Tripped)
Off Normal (Reset)

Warning!
In latching relay mode, latched relays will reset
(unlatch) when power is cycled.

In this application, the meter is set up for automatic reset (non-latching

either the LED or the relay. When the alarm finally goes away, the relay
automatically resets and the LED also goes off.

In this application, the meter is set up for automatic and manual reset at
any time (non-latching relay). The LED and the relay automatically reset
when the meter returns to the normal condition.
The next time an alarm occurs, the operator acknowledges the alarm
manually while the alarm condition still exists. This causes the relay to
reset, but the LED stays on until the meter returns to the normal
condition.

In this application, the meter is set up for manual reset only after the
signal passes the reset point (alarm condition has cleared).
Acknowledging the alarm while it is still present has no effect on either
the LED or the relay. When the alarm is acknowledged after it returns to
the normal state, the LED and the relay go off. Notice that the LED
remains on, even after the meter returns to the normal condition. This is
because, for latching relays, the alarm LED reflects the status of the
relay, regardless of the alarm condition.
Acknowledging Relays
There are two ways to acknowledge relays programmed for manual
reset:
1. Via the programmable front panel function keys F1-F3 (Default:
F3 assigned to ACK).
2. Remotely via a normally open pushbutton wired across one of
the digital inputs and the +5 V terminals on the digital I/O
modules, or using the F4 digital input, which is triggered with a
contact closure to COM, or with an active low signal (see page
25).
When the ACK button or the assigned digital input is closed, all relays
programmed for manual reset are acknowledged.

Interlock Relay Operation Example
Relays 1 & 2 are configured to energize (their front panel LEDs are off)
when SW1 & SW2 switches (above) are closed. If the contacts to these
digital inputs are opened, the corresponding front panel LEDs flash
indicating this condition. The processes being controlled by the interlock
relay will stop, and will re-start only after the interlock relay is reactivated by the digital inputs (switches).
Note: If multiple digital inputs are assigned to the same relay, then the
corresponding logic is (AND) – i.e. both switches must be closed to trip
the relay.
Scaling the 4-20 mA Analog Output (Aout)
The 4-20 mA analog output can be scaled to provide a 4-20 mA signal
for any display range selected.
No equipment is needed to scale the analog output; simply program the
display values to the corresponding mA output signal.
