5.9.3 Setting P9L3, Load Shed Delay (LSDL)
P9L3 sets both the pickup and dropout delays in seconds for the load
shed output. That is, it sets the time for which the current must be
above LSPU before the output is activated. It also sets the time for
which the current must be below LSDO before the output is deacti-
vated.
The LSPU and LSDO settings are forced to be coherent:
• If the User sets either to OFF, the other is automatically set
to OFF as well.
• If LSPU is set to any pickup value with LSDO OFF, LSDO is
set to its minimum on-setting, 50 percent of FLA. The User
can set it to a different value if desired.
• If LSDO is set to any dropout value with LSPU OFF, the
LSPU is set to its maximum value, 150 percent of FLA. The
User can set it to a different value if desired.
• LSPU must be greater than LSDO. The setting range of
either may be limited to enforce this.
5.9.4 Settings P9L4 through P9L25, alarm and Trip assignments
to aUX1
If LSPU and LSDO are both set to OFF, all other available functions
for AUX1 become visible and can be individually turned on or off.
AUX1 is activated if any of the designated functions picks up, with an
OR logic function. Other than the three load shed function settings, the
remaining settings are the same as the 22 listed for SP AREL page in
Section 5.8. The AUX1 output operates if any of the selected functions
become true.
5.10 Page 10, SP aUX2, Settings P10L1 to P10L23
This page determines which events activate the output relay AUX2. It
also includes the setting to enable the transition function. The factory
settings configure AUX2 to pick up for the transition function.
NOTE: The operating specifics of the transition function must be
configured on the SP START Page 5, Settings P5L5 to P5L9,
if the transition function is set ON here with P10L1.
5.10.1 Setting P10L1, Enable Transition Control Output
(TRN ON or TRN Off)
P10L1 enables the transition function through output relay AUX2. If
ON, the AUX2 relay is activated when the motor transitions from the
START state to the RUN state, and deactivated when the next motor
STOP is declared. Consider MODE 1 versus MODE 2 activation as set
by P12L4 described in Subsection 5.12.4.
5.10.2 Settings P10L2 through P10L23, alarm and Trip
assignments to aUX2
If the transition function is OFF, all the other functions for AUX2
are visible. The settings are the same 22 selections as those in the
SP AREL page. Refer to Subsection 5.8. The AUX2 output operates if
any of the selected functions become true.
5.11 Page 11, SP a OUT
This page configures the operation of the 4-20 mA analog output.
5.11.1 Setting P11L1, analog Output function (MaX XXXX)
P11L1 selects the internal MP-3000 parameter represented by the
4-20 mA analog output. Select one of these choices:
MP-3000
www.eaton.com
MaX 100–100% of fLa - proportional to the average of the three-
phase current values, with 100% of FLA = 20 mA and 0% = 4 mA.
MaX 125–125% of fLa - proportional to the average of the three-
phase current values, with 125% of FLA = 20 mA and 0% = 4 mA.
MaX %I2T-Percent of I2T Trip Level - proportional to the percent I2T
trip level (thermal-model accumulator bucket), with 100% percent of
the I2T Trip Level = 20 mA and 0% = 4 mA.
MaX WRTD - Winding temperature—proportional to the maximum
winding RTD temperature from the URTD module. The winding RTD
trip level (setting P2L2) = 20 mA and 0°C or 32°F = 4 mA.
5.12 Page 12, SP SyS, Settings P12L1 to P12L18
Page 12 configures overall operation of the MP-3000.
5.12.1 Setting P12L1, Configure Trip Relay Output
(TP MODE1 or TP MODE2)
P12L1 selects Mode 1 or Mode 2.
MODE 1 - the trip relay is normally de-energized. The trip relay ener-
gizes on a trip event.
MODE 2 - the trip relay energizes on power up and de-energizes on a
trip event. Mode 2 is also called the fail-safe (factory set) mode.
Each of the output relays has a form C (SPDT) contact set, so that
combining output modes and contact choices gives four logical com-
binations. Note the key difference in using Mode 2 with the normally-
open contact versus using Mode 1 with the normally-closed contact.
With Mode 2 and a normally-open contact, the external circuit closes
during normal non-trip operation. It opens for a trip, if the MP-3000
power supply is de-energized, or the unit fails. With Mode 1 and a
normally-closed contact, the external circuit opens only for an overt
trip decision, and is maintained when the MP-3000 is de-energized.
The MP-3000 is normally set for Mode 2 operation of the TRIP and
ALARM relays.
5.12.2 Setting P12L2, Configure alarm Relay Output (aL MODE1
or aL MODE2)
Select Mode 1 or Mode 2 operation of the alarm relay. Refer to
Subsection 5.12.1. The factory default is fail-safe MODE 2.
5.12.3 Setting P12L3, Configure aUX1 Relay Output (aX1 MOD1 or
aX1 MOD2)
Select Mode 1 or Mode 2 operation of the AUX1 relay. Refer to
Subsection 5.12.1. The factory default is MODE 1.
5.12.4 Setting P12L4, Configure aUX2 Relay Output (aX2 MOD1 or
aX2 MOD2)
Select Mode 1 or Mode 2 operation of the AUX2 relay (see subsection
5.12.1). The factory default is MODE 1.
5.12.5 Setting P12L5, auto or Manual
(MaN I2T or aUTO I2T)
Select AUTO I2T to set this particular alarm function to automatically
reset when the thermal-model bucket level drops below alarm setting
P4L2 (I2TA XX). Select MAN I2T to perform a reset only after the
thermal-model bucket level drops below the alarm setting P4L2 (I2TA
XX) and a manual reset command is given. The RESET command
can come from the front-panel Reset button, the PowerNet communi-
cations host, or a remote contact. A remote reset contact, if used, is
