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
figure
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 field to ECC operation.
mRoy
®
A/B pumps manufactured before 1987
cannot be converted in the field 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 field 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 retrofit kit replaces
the old circuit board with a new unit. Match your
Milton Roy pump to the correct circuit board retrofit
kit part number using Table 9. Refer to Circuit Board
retrofit kit installation (paragraph 2.7).
2.1.3 Circuit Board Replacement For ECC(s)
Built After January 2000 and/or After A
Circuit Board Retrofit Kit Is Replaced.
After a conversion kit is installed in the field 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 configured for your pump.
This will eliminate problems during installation.
Refer to Printed Circuit Board Replacement
(paragraph 4.4, Section 4).
