I.L. 17562
PR 0.3 Effective 8/99
5.12.3 Setpoint P12L3, Configure AUX1 Relay Output (AX1 MOD1 or AX1 MOD2) —
Select
Mode 1 or Mode 2 operation of the AUX1 relay - see 5.12.1 above. The factory default is MODE
1.
5.12.4 Setpoint P12L4, Configure AUX2 Relay Output (AX2 MOD1 or AX2 MOD2) —
Select
Mode 1 or Mode 2 operation of the AUX2 relay - see 5.12.1 above. The factory default is MODE
1.
5.12.5 Setpoint P12L5, Auto or Manual I
2
T 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 the alarm setting P4L2 (I2TA XX). Select MAN I
2
T to 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,
from the PowerNet communications host, or from a remote contact . A remote reset contact, if
used, is connected to one of the digital input channels; and that channel must be programmed
for REM RST (remote reset) or RST DBL (reset disable).
5.12.6 Setpoint P12L6, Enable Programming with a Running Motor (RUN PGM or
STOP PGM) —
If RUN PGM is selected, the motor may be started and/or run during
programming of the MP-3000 setpoints. If STOP PGM is selected, the motor must be stopped in
order to enter the PROGRAM mode, and starting is blocked.
NOTE
If you want to take full advantage of the ARMED/DISARMED capability of the MP-3000 as
described in P12L18 below, be sure to set P12L6 to RUN PGM.
With RUN PGM, if the user reprograms the MP-3000 while the motor runs, the relay continues to
protect with the all the old setpoints. All setpoint changes are stored in a scratchpad area and
not immediately used. Finally, when the reprogramming is finished, the user exits the
PROGRAM mode by pushing the
Program
button again - see Section 4. Only at this moment
does the MP-3000 recalculate its internal values and put the new setpoints into effect. Note what
happens when it does so:
•
Thermal-model accumulator bucket is dumped and resets to 40 degrees C.
•
Any active run delay timers are reset and must start timing again.
•
All jogging functions are reset - time between starts, cold starts, and starts per time limits are
all cleared.
•
The MP-3000 remembers that it was in the RUN state when the program mode was exited,
and continues that state. The transition function will not reset, or trigger a reduced-voltage
starter to switch to reduced voltage.
5.12.7 Setpoint P12L7, Emergency Override Enable (EMRG EN or EMRG DIS) —
Select if
the emergency override button is enabled or disabled. If enabled, an emergency override can be
executed by pushing the
Emrg Override
button behind the front-panel security door. In any
case, an emergency override can be performed by a remote contact connected to either of the
discrete inputs DI1 or DI2 programmed as EMG OVR; or via data communications from a
PowerNet host. The as-shipped setting is disabled.
