5.9.4

Settings P9l4 through P9l25, alarm and Trip assign-

ments 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

Subsection 5.8. The AUX1 output operates if any of the selected func

tions 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

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-4000 parameter represented by the

4-20 mA analog output. Select one of these choices:

MaX 100–100 percent 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 percent 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% 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.

Page 12 configures overall operation of the MP-4000

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-4000

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-4000 is de-energized.

The MP-4000 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 (see 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 (see 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

I2T Reset (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

) an

d 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

connected to one of the digital input channels. That channel must be

programmed for REM RST (remote reset) or RST DBL (reset disable).

5.12.6 Setting P12l6, Enable Programming with a Running Mo-

tor (RUN PGM or STOP PGM)

If RUN PGM is selected, the motor may be started and/or run during

programming of the MP-4000 settings. If STOP PGM is selected, the

motor must be stopped in order to enter the PROGRAM mode, and

starting is blocked while in the Program mode.
