iInstallation, Operations & Maintenance Manual
PRECAUTIONS
The following precautions should be taken when working with metering pumps.
Please read this section carefully prior to installation.
Protective Clothing
ALWAYS wear protective clothing, face shield, safety glasses and gloves when working on or
near your metering pump. Additional precautions should be taken depending on the solution
being pumped. Refer to Safety Data Sheets for the solution being pumped.
Hearing Protection
It is recommended that hearing protection be used if the pump is in an environment where the
time weighted average sound level (TWA) of 85 decibels is exceeded (as measured on the A
scale slow response).
Electrical Safety
• Remove power and ensure that it remains off while maintaining pump.
• DO NOT FORGET TO CONNECT THE PUMP TO EARTH.
• Electric protection of the motor (Thermal protection or by means of fuses) is to correspond
to the rated current indicated on the motor data plate.
Liquid Compatibility
Verify if the materials of construction of the wetted components of your pump are
recommended for the solution (chemical) to be pumped.
Pumps Water “Primed”
All pumps are tested with water at the factory. If your process solution is not compatible with
water, ush the Pump Head Assembly with an appropriate solution before introducing the
process solution.
Plumbing and Electrical Connections
Always adhere to your local plumbing and electrical codes.
Line Depressurization
To reduce the risk of chemical contact during disassembly or maintenance, the suction and
discharge lines should be depressurized before servicing.
Over Pressure Protection
To ensure safe operation of the system it is recommended that some type of safety/pressure -
relief valve be installed to protect the piping and other system components from damage due
to over-pressure.

Installation, Operations & Maintenance Manual
SECTION 1 - GENERAL DESCRIPTION
1.1 GENERAL INFORMATION
In this age of sophisticated process control
concepts, many people are taking advantage of
the latest breakthroughs in technology to upgrade
their own equipment and systems. The Milton
Roy Electronic Capacity Control (ECC) easily
interfaces with computerized process and process
instruments, as the ECC will adjust the output of a
metering pump from 0% to 100% in response to a
4 to 20 mA or 1 to 5 VDC signal from a computer
or other source. This outstanding feature can be
purchased as an integral part of the pump, or it can
be bought separately and eld installed. The ECC
mounts to the housing of the pump and operates
in place of the manual stroke adjustment.
1.2 PRINCIPLE OF OPERATION
The ECC allows remote adjustment of the
volume of liquid delivered by the metering
pump. This is accomplished by utilizing a
4-20 mA command signal from a Milton Roy
Remote Panel Mount (ARPM-100/200) or Remote
Wall Mount (ARWM-100/200) remote controller
(Manual No 53944), or a customer’s control
system. In a closed loop control system, the ECC
accepts the computer or controller 4-20 mA signal
directly and provides immediate and accurate
control of the pump ow under varying process
conditions.
SECTION 1 - GENERAL DESCRIPTION
When the ECC receives the 4-20 mA command
signal, the drive motor responds by moving the
ECC to the required position. As the ECC moves,
it changes the position of the pump’s stroke adjust
shaft, thus altering the pump’s ow rate. Refer to
Table 1 which lists reference manuals containing
information on the stroke adjust shaft and pump
operation.
Table 1. Stroke Adjust Shaft & Pump
Operation Reference Manuals
NOTE:
As supplied, the ECC is direct acting (pump
capacity increases with increasing input signal
to ECC) although it may be converted to reverse
acting by following the procedure outlined in
Section 3, “Operation”.

MAXROY®B, mRoy®, MACROY®and Milroyal®
product family pumps can be ordered with or
without an ECC already attached. If the ECC is
ordered with the pump, it is indicated in the pump
model code by an “E1”, “E2”, “EA” or “EB” in the
capacity adjustment slot. The pump model code
can be found on the pump data plate, mounted to
the pump.
There are four ECC’s customarily supplied with
a pump; these models are shown in the product
model code tables (Table 2 - Table 8). There are
several very similar ECC data plates and some of
these are shown in Figure 1 and Figure 2. Please
note that the Figure 2 data plate documents what
safety and/or hazardous location approvals apply
to the unit.

Installation, Operations & Maintenance Manual
SECTION 2 - INSTALLATION
2.1 GENERAL INFORMATION
The ECC is usually shipped already mounted to
the pump. Installation, therefore, is usually only a
matter of connecting the signal wiring (paragraph
2.6.1) and primary power wires (paragraph 2.6.4).
Model numbers containing (-I) are IECEX/ATEX
approved. Actuators containing (-I) model code
will come with the locking set screw in the base
(see gure 15B). Unlock the set screw for cover
removal. Tighten the set screw to lock the cover
to maintain rating and prevent tampering. Hex key
for set screw adjustment is shipped with actuator.
2.1.1 Field Installation of ECC
Field installation of the ECC to an existing pump
is usually not recommended due to the precise
alignment required.
MACROY®G and MACROY®D pumps cannot be
converted in the eld to ECC operation.
mRoy®A/B pumps manufactured before 1987
cannot be converted in the eld to ECC operation.
The mRoy®A/B pump housing must have
been machined to mount an ECC. Contact the
Milton Roy service department if you wish to convert
a manually adjusted mRoy®pump manufactured
after 1987 to ECC operation.
If the ECC was supplied as a field mounting
kit, refer to eld installation instructions for the
following pumps; MAXROY®B (Appendix A),
Milroyal® B (Appendix B) or Milroyal®C (Appendix C).
Upon completion of the retrofit, proceed with
service connections (paragraph 2.4).
2.1.2 ECC Circuit Board Replacement
As ECC circuit boards fail (ECC(s) built before
January 2000) at field installations, they are
replaced with an ECC circuit board retrofit kit
(see Table 9). The circuit board retrot kit replaces
the old circuit board with a new unit. Match your
Milton Roy pump to the correct circuit board retrot
kit part number using Table 9. Refer to Circuit Board
retrot kit installation (paragraph 2.7).
2.1.3 Circuit Board Replacement For ECC(s)
Built After January 2000 and/or After A
Circuit Board Retrot Kit Is Replaced.
After a conversion kit is installed in the eld and/or
a new ECC circuit board (ECC(s) built after January
2000) fails order replacement board p/n 30300 for
all pumps except Milroyal®C. Order p/n 39320 for
Milroyal®C pumps.
NOTE:
When ordering the replacement board
(p/n 30300/39320) specify what pump the unit
is being installed on to insure the replacement
board is congured for your pump.
This will eliminate problems during installation.
Refer to Printed Circuit Board Replacement
(paragraph 4.4, Section 4).

2.2 UNPACKING
Units are shipped Free on Board (FOB) factory
and the title passes to the customer when the
carrier signs for receipt of the unit. In the event
that damages occur during shipment, it is the
responsibility of the customer to notify the carrier
immediately and to le a damage claim.
Carefully examine the shipping crate/box upon
receipt from carrier to be sure there is no obvious
damage to contents. Open the crate/box carefully
so accessory items fastened to the inside of the
crate/box will not be damaged or lost. Examine
all material inside crate/box and check against
packing list to be sure that all items are accounted
for and intact.
2.3 STORAGE/IDLE SERVICE
Several ECC components are steel and are subject
to corrosive attack during storage/idle time in hot,
humid environments. The ECC covers are not air
tight. In humid environments, the humidity in the
air can condense during cooler evenings, even
to the extent that water can accumulate inside
the housing. Milton Roy does not warrant against
damage caused by corrosion or atmospheric
conditions.
With reasonable care at the site, the products and
packaging methods will effectively protect new,
uninstalled units from corrosion due to water and
water vapor for up to one year.
FAILURE TO PROPERLY STORE
AND PROTECT THE EQUIPMENT
MAY VOID ANY WARRANTY, EXPRESSED OR IMPLIED.
OUTDOOR STORAGE IS NOT RECOMMENDED UNDER ANY
CIRCUMSTANCES UNLESS SPECIFICALLY PREPARED FOR
STORAGE PRIOR TO SHIPMENT FROM THE FACTORY.
The amount of time the ECC can remain in storage
or idle service can be extended. Depleted, factory
installed desiccant can be removed and replaced
with new desiccant. Visit the factory website
(www.miltonroy.com) for instructions to properly
extend ECC storage.
Maximum Estimated Storage
2.4 SAFETY PRECAUTIONS
When installing, operating, and maintaining
the ECC, keep safety considerations foremost.
Use proper tools, protective clothing and eye
protection when working on the equipment and
install the equipment with a view toward ensuring
safe operation. Follow the instructions in this
manual and take additional safety measures
appropriate to the liquid being pumped. Be
extremely careful in the presence of hazardous
substances (e.g. corrosives, toxics, solvents, acids,
caustics and ammables etc.)
2.5 MOUNTING
The Milton Roy ECC is commonly shipped already
mounted on a pump. Because of this, installation
usually requires connecting the power and signal
wires. If the ECC was shipped without a pump,
mounting to your pump and minor calibration
adjustment is required (Full calibration is performed
at the factory and only limited calibration is required
after mounting). ECCs installed on pumps outdoors
should be protected by a shelter. Care should be
taken to keep condensation and moisture from
entering via the electrical conduit.

SECTION 2 - INSTALLATION
2.6 WORKING WITH THE COVER
Explosion proof units have a set screw in the
base to lock the cover after it’s installed. This is
to maintain the explosion proof rating and prevent
tampering. On explosion proof units, to remove
the cover, rst loosen the set screw in the base
using a 5/64” hex key. Then unscrew the cover.
To install the cover, screw it on all the way. The
cover can be torqued to 15 lb.ft (20 N.m). Then
snug the locking set screw in the base using a 5/64”
hex key to prevent the cover from being unscrewed.
2.7 ELECTRICAL CONNECTIONS
The electrical connections for the ECC are input
signal, feedback output signal, and input power.
Terminal blocks, with removable connectors are
located on the bottom of the circuit board under
the ECC cover. Conduit access to the ECC is via
two threaded 1/2-14 inch NPT threaded openings
in the ECC base.
The Milton Roy ECC is commonly shipped with
red ½ - 14 inch NPT plastic plugs in the conduit
access openings. During installation, remove
these shipping plugs and do not use them. Use
appropriate cable glands instead. For IECEx
installations, use an explosion proof conduit seal
applied by the installer or user of the equipment
according to code.
All wiring should conform to National Electrical
codes or local codes as they apply. Conduit
bushings must be chosen to provide NEMA 4,
and explosion proof integrity. In North America,
use NEMA type 4 and/or explosion proof conduit
ttings. In Europe, cable glands with IP66 and/or
Ex d ratings are readily available with 1/2-14 inch
NPT threads.
ALWAYS DISCONNECT PRIMARY
POWER BEFORE REMOVING
THE COVER FROM THE ECC. FAILURE TO FOLLOW THESE
INSTRUCTIONS COULD RESULT IN DEATH OR SERIOUS
INJURY.
AVOID DAMAGE TO SENSITIVE
ELECTRONICS, REMOVE THE
COVER FROM THE ECC CAREFULLY
2.7.1 Installation of Input/Output Command
Signal Wiring
1. To remove the cover: explosion proof units have
a set screw in the base that locks the cover when
it is closed and maintains its explosion proof
rating. To remove the cover, rst loosen the set
screw in the base using a 5/64” hex key.
2. Unscrew the ECC cover by turning it
counterclockwise (as viewed from the top).
Lift the cover straight off and away.
IMPROPER CONNECTION OF
THE COMMAND LINES CAN
CAUSE DAMAGE TO THE ECC. USE ONLY 300 VOLT, 105°C
RATED WIRE, MINIMUM 22 AWG, MAXUMUM 14 AWG.
3. Maintain integrity of safety approvals using
only 300 volt, 105° C (UL 1213 or equiv.) rated
insulation. Maintain CE immunity ratings, using
shielded cable inside of conduit.
4. Feed four (14 to 22 AWG) shielded wires
through appropriately rated conduit bushing
inserted into one of the conduit holes in base
of ECC. Ground shields for four wires to a good
chassis ground at control end.
5. Route wires to ECC keeping electrical
interference to a minimum. Carefully pull
four-position connector J5 from circuit board.
Connect command signal wires to connector
J5 (Figure 4 and 12). Reconnect connector J5
to circuit board.

2.7.2 Input Signal
The input signal, used to control the ECC, can
be either 4-20 mA or 1-5 VDC. A ve-position Dip
switch, SW2 (Figure 11, located on the top of the
circuit board) selects the control signal used by
the operator. The factory sets SW2 for the model
ordered and should not need changed. Position 1
(Table 10) of SW2 sets the input signal. Position 2
sets the movement of the ECC after unintentional
loss of the control signal. Position 3 and 4 sets
the ECC for use with a pump or valve and should
always be set to 3-OFF and 4-ON for the pump
mode. Position 5 is not used.
2.7.3 Feedback Output Signal
A position output, proportional to ECC position,
is used for remote position indication. A current
of 4-20 mA or a voltage of 1-5 VDC is available
between MONITOR (J5-4) and COMMON (J5-3).
Feedback zero and feedback span adjustments
(Figure 11) are provided to ne tune the output
(see calibration instructions). DIP switch SW3
(Figure 11) selects the feedback output signal. Use
of the output signal is optional.
2.7.3.1 Feedback Output Signal 4-20 mA
NOTE
Do not connect the 4-20 mA output to a circuit
with greater than a 500 ohm load.
Set SW3 per Table 11 for a 4-20 mA feedback
signal.
2.7.3.2 Feedback Output Signal 1-5 VDC
NOTE
Do not connect the 1-5 VDC output to a circuit
having less than 250 ohms impedance.
Set SE3 per Table 11 for a 1-5 VDC feedback
signal.
