PR 0.3 Effective 8/99
5.4.3 Setpoint P4L3, Jam Alarm Level (JMA) —
Sets the current limit in percent of FLA at
which the jam alarm picks up. This alarm can be set to OFF. Set to a lower level than the jam
trip level P3L6. The start delay is the same as for the jam trip function; see P3L7. Use with run
delay, next.
5.4.4 Setpoint P4L4, Jam Alarm Run Delay (JMAR) —
Sets the number of seconds that the
jam alarm level must be maintained before the alarm occurs.
5.4.5 Setpoint P4L5, Underload Alarm Level (ULA) —
Specifies the current level in percent of
FLA below which the MP-3000 alarms. The start delay is the same as for underload trip; see
P3L10. Use with the underload run delay, next. Note: ULA must be set to a higher current
value than the underload trip level P3L9.
5.4.6 Setpoint P4L6, Underload Alarm Run Delay (ULAR) —
Sets the number of seconds that
the current must remain below the underload alarm limit before the alarm occurs.
5.4.7 Setpoint P4L7, Phase Unbalance Alarm Level (UBA) —
Sets the percent of phase
current unbalance above which the MP-3000 alarms. This alarm can be set to OFF. The start
delay is the same as for the phase unbalance trip; see P3L13. Use with unbalance alarm run
delay, next. See P3L12 above, unbalance trip level, for more information.
5.4.8 Setpoint P4L8, Phase Unbalance Alarm Run Delay (UBAR) —
Sets the number of
seconds that a phase unbalance alarm must be maintained before the alarm occurs.
5.5 Page 5, SP START, Setpoints P5L1 to P5L12 —
This page contains setpoints that control
motor starting and jogging functions.
5.5.1 Setpoint P5L1, Starts Per Time Allowed (ST/T) —
Sets the maximum number of motor
starts permitted within the time set in P5L2, next. To disable this function, set P5L2 to OFF.
The record of recent start times is kept in a memory stack; the oldest starts in the memory are
deleted as they age beyond the time limit set below in P5L2. If the maximum number of starts is
reached within the set time window, the relay raises an alarm with STEX A on the display. To
observe the per time limiting values, check the
remaining starts RMST
and
time until start
TUS
displays on the
monitor
page.
After the motor stops, the relay trips with the message STEX XXX where XXX is the number of
minutes before the oldest start is deleted from the memory stack, allowing the motor to start.
XXX can be observed to count down as the motor sits idle.
5.5.2 Setpoint P5L2, Time Allowed For Starts Count (T/ST) —
Sets the number of minutes
within which the maximum number of starts cannot be exceeded. This function can be set to
OFF.
5.5.3 Setpoint P5L3, Time Between Starts (TBS) —
Sets the time in minutes that must expire
from one start until the next is permitted. This function can be set to OFF.
