FLUSH MOUNTING MULTI-FUNCTIONAL PROTECTIVE RELAY
WITH AMMETER
EOCR-FDM
Selectable characteristic : Defirite / Inverse Time
Introduction
BASED ON MCU(Micro Controller Unit) AND ADOPTED
ASIC(Application Specific intergrated Circuit) CHIP
MULTI-FUNCTIONAL PROTECTION : OVERCURRENT,
PHASE REVERSAL, PHASE LOSS, PHASE UNBANCE,
LOCKED ROTOR.
1. The real current of 3 phases are displayed in sequence.
2. Possible setting with potentiometer at outside of panel.
(overcurrent, delay time, operating time, alert)
3. Selectable functions and CT ratios with DIP switches.
(phase reversal, phase loss, time-current characteristic,
alert signal)
4, Bar graph is displayed percentage of actual current
compared with preset current.
Dip switch selection guide
How to set up
1. CURRENT : Definte Time-Set the rated motor
current by "CURR" potentiometer. For pro-tection
of connected machinent is stabilized.
Inverse Time - 100% of rated motor current or actual
2. D-TIME : Set the expected run-up time of motor by "D-TIME" potentiometer.
3. O-TIME : Definte Time - Set the desired trip delay time.
(from over the preset current to internal relay de-energize.)
Inverse Time-Set the trip delay time according to
Time-Cirrent characteristics.
Select the characteristic by DIP switch #3.
4. ALERT : After motor run-up, slowly turn the "ALERT" potentionmeter
CCW,
until the"A" flashes and number displayes
on the screen. Then the number
indicates the load factor of the motor. Refer to "FUNCTION
AND INDICATION OF ALERT"
for output.
