41, 3 SETUP AND USE 3-2 3.1 Controls and Indicators Once the 269 relay has been wired and control power applied, it is ready to be programmed for the given application. Programming is accomplished using the 12 position keypad and 48 character alphanumeric display shown in Figure 3.1. The function of each key on the keypad and each of the indicators is briefly explained in Table 3-1. Table 3-1 Controls and Indicators No. N…

27, 2 INSTALLATION 2-18 2.12 Emergency Restart Terminals If it is desired to override relay trips or lock-outs and restart the motor, a normally open keyswitch should be installed between terminals 54 and 55. Momentarily shorting these terminals together will cause the thermal memory of the 269 to discharge to 0% (if RTD input to thermal memory is enabled, thermal memory can be reduced to 0% by keeping terminals 54 and 55 shorted together fo…

85, GE MULTILIN 269 MOTOR MANAGEMENT RELAY Series 3 SETUP AND USE 3-46 3.11 Ground Fault (Earth Leakage) Set- points Aging and thermal cycling can eventually cause a low- ering of the dielectric strength of the insulation in the stator winding. This can produce a low impedance path from the supply to ground resulting in ground fault currents which can be quite high in solidly grounded systems. In resistance grounded systems there is a resistance in series with the supply source to limit ground fault current and allow the system to continu…

Where the motor is started unloaded and the field ap- plied later in the start, the power factor may be poor until the motor is loaded and synchronous speed is attained. It may then be necessary to …

If an alarm feature is assigned to no relay, it can still become active (ie. cause the appropriate alarm message to be dis- played if setpoints are exceeded) but no output relay activation will occur.
