3.5 SETPOINTS MODE
In SETPOINTS mode any or all of the motor trip/alarm setpoints may be either viewed or altered. This mode is
divided into seven seperate pages of data each of which contains a different group of relay setpoints.
The [SETPOINTS] key must be pressed to enter SETPOINTS mode. If no key is pressed for more than four
minutes in this mode, the display automatically goes into ACTUAL VALUES mode (see Section 3.4 ACTUAL
VALUES MODE above for details). Press the [SETPOINTS] key to return to SETPOINTS mode. When
pressed, the following flash message will appear on the display,
The display will then show,
which is the first line of Setpoints page 1. The [PAGE s][PAGEt], [LINE s], and [LINE t] keys (see Section
3.2: CONTROLS AND INDICATORS on page 3–2) may then be used to view the setpoints data.
The [VALUE s], [VALUE t], [STORE], and [CLEAR] keys (see Section 3.2: CONTROLS AND INDICATORS
on page 3–2) are used to change setpoints. Before any setpoints can be changed, however, the access termi-
nals must first be shorted together (see Section 2.17: PROGRAMMING ACCESS TERMINALS on page 2–22).
The [PAGE s], [PAGE t], [LINE s], and [LINE t] keys are used to scroll between setpoints. The setpoint
values changed with the [VALUE s]/[VALUEt] keys. The [CLEAR] key returns setpoints to their original val-
ues. When the setpoint value is chosen, press the [STORE] key to save the value into the relay memory. When
the STORE key is pressed, the following flash message is displayed and the new setpoint value implemented,
If an attempt is made to save a new setpoint value without the access terminals shorted together, the new
value is ignored and the flash message is displayed,
To ensure that setpoints are tamperproof, the access terminals should be shorted together only when setpoints
are to be changed. Setpoints may be changed while the motor is running; however, it is recommended that the
motor is stopped before important protection parameters are changed. Setpoints are stored indefinitely in non-
volatile memory even when control power to the unit is removed.
All seven pages of data and the lines in each page are as shown in Table 3–3: 269Plus SETPOINTS on page
3–18. Also shown are the default settings, the ranges and increments for each setpoint. It should be noted that
the 269Plus motor protection parameters are based on the data entered by the user. Thus this data must be
complete and accurate for the given system.
