ATC DIVERSIFIED ELECTRONICS MPA2 User manual

GENERAL DESCRIPTION
MOTOR PERFOMANCE ANALITZER
MPA2 is an electronic Motor Performance Analyzer that constantly monitors motor current and power supply voltage, using a thermal
model algorithm to protect your motor against undercurrent, overload conditions, and voltage failures.

WARNING: Only qualified technicians with knowledge
about overload relays and associated machinery should do
the installation, starting up, and maintenance of the system.
Failure to comply may result in personal injury and/or
equipment damage.
CAUTION: This product may start automatically, the user
must take cautions to avoid hazards to people.
CAUTION: This product has been designed for
CAUTION: An incorrectly applied or installed product
can result in damage to the components or reduction in
product life. Wiring or application errors, or operating/storing
in excessive ambient temperatures may result in malfunction.

industrial environments . Use of this product in residential
enviroment may cause unwanted electromagnetic
disturbances in which case the user may be required to
take adequate mitigation measures.

b) Place over flat surface panel and install it using a screwdriver
suitable for screws 3/16” x 1/2”.
Recommendation for Flat Surface Mounting:
Make two (2) holes ( 5/32”) on panel surface before installing.
See as reference the Guide for Flat Surface Mounting
shown in point 5 (General Dimensions).

WARNING:(Risk of Electric Shock). Disconnect power
supply before installing . Electric Shock will result in serious
injury or death.
Recommendations for Wiring:
· Avoid over tightening the M3 screws upon terminals during wiring
connection.Tightening Torque: 4.4 lbf-in, 5.1 Kgf - cm.
· Wire Strip Length 1/4” (6-7 mm).
· Terminal wiring size: between AWG 10 and AWG 18.
· Current wiring size: AWG 4, Ø: 7/16” (11mm).
· Connect L1L2L3 terminal for Voltage Input in parallel connection before
line starter circuit through Contactor (as shown in Basic Diagram
Installation).
· Use three Current Sensing Holes for passing wires before connection
to 3 phases motor. Using less than three (3) wires shall cause
current unbalance wrong measures.

Refer to point 10 for detail explanation.
MPA2 constantly monitors current and voltage values. When any
harmful condition occurs, the output connection is deactivated until
the fault disappears and power line conditions return to an acceptable level.
Specific
timing such as Start Up Delay and Fault Detection Delay are incorporated
to
prevent nuisance tripping due to rapid power fluctuations.
Provides LCD Display to indicate the output status (voltage, current,
unbalance, frequency and load status). Also provides four (4) push buttons
(On/Off, Up, Down and Select) for electrical parameter adjustment such as
Voltage, Current, Frequency, Fault Detection Delay and others. Besides these
mentioned advantages, a Communication Port with MODBUS RTU protocol
is included.

8.1 Instructions for Mechanical Dismounting (DIN RAIL)
a) Handling a Flat Screwdriver, pull downward the mounting bracket that
you can see at rear and down side as shown in figure.
8.2. Instructions for Mechanical Dismounting
(FLAT SURFACE)
Unscrew both screws fixed on Flat Surface through attachable mounting
ears and then pull out the relay from flat surface as shown in figure.
b) With screwdriver at position (2), pull out from DIN Rail as
shown in figure:
Recommendation for DIN Rail Dismounting:
Pull downward 2 mm with a soft movement when using screwdriver
for dismounting. Strong movement could break the supporting bracket.

1) Model identified as MPA2-240-CT and MPA2-480-CT is exclusively used
with external CTs.This model protects motors with rated current up
to 660 A.The CTs are not included.
2) User must specify motor rated current. With this data select a
Nominal current range accordingly to adjacent table, getting then
/5 relationship required external CTs to install.
3) Then user must program with external CT adding the adjustment
instructions contained in this application.
4) Calibration is kept guaranteed as long as external CTs are
Commercial Class 1 Secondary 5A.
