SETPOINTS MODE 3 SETUP AND USE

514
This setpoint tells the 269Plus to use the learned motor cooling time values. (see Actual
Vales page 6). When learned values are not used, the user entered values are used.
Range: YES (default cool times); NO (learned cool times from Actual Values page 6)
This setpoint should not be changed unless the 269Plus has learned
reasonable motor cool down times.
Factory Value = YES
515
This setpoint is seen when the learned motor cooling times are not used. It represents the
time for the thermal memory to discharge from 100% to 0% with the motor running in a non-
overload condition:
Range: 1 to 45 minutes in steps of 1 minute (cooling time in minutes)
Factory Value = 15 minutes
516
This setpoint is seen when the learned motor cooling times are not used. This value
represents the time for thermal memory to discharge from 100% to 0% with the motor
stopped. The OVERLOAD TRIP lockout time is 85% of this value (see Section 3.22).
Range: 5 to 213 minutes in steps of 1 minute (cooling time in minutes)
Factory Value = 30 minutes
517
This setpoint is used to select RTD10 as an ambient air temperature sensor; see Section
3.22. This message is not displayed if the ARE THERE ANY RTD CONNECTED? setpoint (page 2,
line 3) is set to NO .
Range: YES, NO
Factory Value = NO
518
This setpoint enables or defeats the Differential Trip function. The 269Plus does not have an
87 element but can accept contact closures from an external differential relay at Terminals 48
& 49 to issue a differential trip. When this value is NO , a contact closure at Terminals 48 & 49
has no effect. Changing this setpoint to NO after a differential trip has the same effect as
when Terminals 48 and 49 are open-circuited and the [RESET] key is pressed, i.e. the
differential trip is automatically reset.
Range: YES (enabled); NO (disabled)
Factory Value = NO
