Product Description

Boasting the optional Ethernet connection of GE Multilin’s 469 series, the 469-P5-LO-A20-T is a Motor Management Relay which can use its Ethernet capabilities to run on the network rather than a mere RS242 or RS485 connection.

The twelve RTD inputs are each 3 wire: those wires are composed of 100 Ω Platinum (DIN.43760), 100 Ω Nickel, 120 Ω Nickel, 10 Ω Copper. The Resistance Temperature Detectors can monitor variables such as hottest temperature to determine when and where problems are cropping up within the system.

469-P5-LO-A20-T GE 469 series Motor Management Relay

The 469-P5-LO-A20-T is capable of monitoring more than just temperature. It can also use its metering capabilities to record values pertaining to amperes, voltage, watts, frequency, and more. Data can be trended and exported from the EnerVista 469 program for analysis by users and technicians. The resulting conclusions from the data can be implemented through the relay’s setpoint system, creating more effective settings based on your system’s unique needs and operating environment.

This unit also features an enhanced faceplate with a wider LCD and more efficient placement of the keypad and LEDs. The display is 40-character, alphanumeric, and is easily viewed under a variety of lighting conditions. The display can also show different system values when not in active use, providing a quick and efficient reference point for users in the vicinity of the relay. The LED indicators also provide reference points, as they are able to turn green, amber, or red depending on the conditions of the system itself.

Frequently Asked Questions about 469-P5-LO-A20-T

What happens when the Relay has stopped or is running cool at times?
This information is supplied when the motor manufacturer is running cool or constant cool times are not provided in the data sheet as issued with the motor. With the resistance temperature detectors and a wired relay, the thermal model has to be used during these critical cooling times. Cooling times usually range between 15 and 30 minutes with the default values and is for the running and stopping cool times.
What should the settings be set at for an acceleration trip on the GE 469-P5-LO-A20-T Relay?
For the GE 469-P5-LO-A20-T Relay acceleration trip, it is apropriate to have the settings set higher than the max starting time, in doing so, this avoids more tripping with a voltage if it were set lower. If the voltage is lowered to a starting usage (set to the acceleration curves) an 18 second setting should be perfect, but if it is an across the line usage of the starting, a 13 second setting should work for this relay.
What if the motor is already hot and the relay has limited starting?
The enable to start a inhibit function can limit starts, espesically when the relays motor is already hot. A GE 469-P5-LO-A20-T Motor Management Relay learns when the relay is hot and how much thermal capacity is used to start, so if the motor is too hot after using some thermal capacity, the relay will not start, especially if the thermal capacity is lower than that is required for a start.
