I.L. 17562
PR 0.3 Effective 8/99
5.12.14 Setpoint P12L14, Date Display Format (M D Y or D M Y) —
Select a display of either
MONTH DAY YEAR or DAY MONTH YEAR.
5.12.15 Setpoint P12L15, IMPACC Communications Mode (IQ2 EN or IQ2 DIS) —
To
configure the MP-3000 to communicate in a manner limited to that of the preceding IQ 1000 II
product, choose IQ2 EN. This is the factory default setting - it is needed for operation with older
IMPACC host systems. To take full advantage of MP-3000 capabilities with a newer PowerNet
host, choose IQ2 DIS. See Section 10, Data Communications, for more details. This setpoint
has no influence on performance or protection behavior of the protective relay itself.
NOTE
For the MP-3000 to communicate with an older IMPACC system, there is a subset of its
setpoints which must be set to within limited ranges or selections which that host system
recognized. See Section 10 for information.
5.12.16 Setpoint P12L16, Internal Diagnostic Failure Action (RLYF TRP, RLYF ALM. RLYF
T+A)
- Selects the action to take if any of the MP-3000 internal background self-monitoring
programs detect a problem with the relay. The factory setting is to trip and alarm. However,
users with critical processes may prefer to set for alarm only so that the motor can continue to
run while maintenance personnel attend to the relay.
CAUTION
If the RLYF ALM setting is chosen, be sure to connect an effective alarm to the alarm relay
output, and test it periodically. Otherwise, the motor runs without protection if the relay suffers a
hardware failure.
5.12.17 Setpoint P12L17, INCOM Trip Enabled or Disabled (INCT EN or INCT DIS) -
Selects
whether or not the MP-3000 will accept and execute a motor trip command from a remote
PowerNet or IMPACC operator via data communications. This is dictated by security concerns
and operating procedures of users who connect the MP-3000 to a facility control system.
5.12.18 Setpoint P12L18, Arm or Disarm Trip Relay (ARMED or DISARMED) —
This
maintenance function blocks the MP-3000 trip output, while all the tripping functions continue to
operate internally. If DISARMED is selected, the relay will still display all alarms and trips but
the trip output relay contact will remain in its non-trip state.
For safety purposes, when the unit is DISARMED, the MP-3000 scrolls a warning message
"WARNING MP-3000 WILL BE DISARMED UPON EXIT OF PROGRAM MODE AND WILL
NOT PROTECT THE MOTOR - ENTER ARMED INTO SETPOINT TO PROTECT THE
MOTOR". The default display says DISARMED, and the Protection LED turns off. Any alarm or
trip messages on the display alternate with the word DISARMED.
In the ARMED mode, the MP-3000 works normally.
The DISARMED mode is useful for commissioning a new relay or new setpoints on a running
motor, when a false trip output would disrupt the process. The user can commission the MP-3000
in the DISARMED mode and observe its behavior, noting any trip operations or filling of the I
