Multilin 469 Motor Management Relay ... - GE Digital Energy

CHAPTER 5: SETTINGS
There are four (4) user-assignable digital inputs configurable to a number of different
functions (see below), or turned Off. Once a function is chosen, any messages that follow
may be used to set pertinent parameters for operation. Each function may only be chosen
once. Assignable Inputs 1 to 4 are activated by shorting D19 to D22 (respectively) with D23.
The range for the INPUT 1(4) FUNCTION settings is: Off, Remote Alarm, Remote Trip, Speed
Switch Trip, Load Shed Trip, Pressure Sw Alarm, Pressure Switch Trip, Vibration Sw Alarm,
Vibration Sw Trip, Digital Counter, Tachometer, General Sw A, General Sw B, General Sw C,
General Sw D, Capture Trace, Simulate Pre-Fault, Simulate Fault, Simulate Pre Fault... Fault.
Two-speed motor protection is enabled with the S2 SYSTEM SETUP CURRENT SENSING
ENABLE 2-SPEED MOTOR PROTECTION settings. If the two-speed motor feature is enabled,
Assignable Input 4 is dedicated as the two-speed motor monitor and terminals D22 and
D23 are monitored for a contact closure. Closure of the contact signifies that the motor is
in Speed 2 or High Speed. If the input is open, it signifies that the motor is in Speed 1. This
allows the 469 to determine which settings should be active at any given point in time.

These settings apply only if the INPUT 1(4) FUNCTION is “Remote Alarm”.
Once the Remote Alarm function is chosen for one of the assignable digital inputs, the
settings messages shown here will follow the assignment message. An alarm relay may be
selected and the name of the alarm may be altered. A contact closure on the digital input
assigned as Remote Alarm will cause an alarm within 100 ms with the name that has been
chosen. Multiple sources may be used to trigger a remote alarm by paralleling inputs (see
FIGURE 5–4: Remote Alarm/Trip from Multiple Sources on page 5–27).
