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
.
NOTICE
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-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.
5.12 Page 12, SP SyS, Settings P12l1 to P12l18
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
XX
) 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.
NOTICE
IF ThE USER WaNTS TO TaKE FUll aDVaNTaGE OF ThE
aRMED/DISaRMED CaPaBIlITy OF ThE MP-4000 aS DE-
SCRIBED IN P12l18 BElOW, BE SURE TO SET P12l6 TO RUN
PGM.
