Page 71 Obtain the requested information (except the acceleration factor) from the motor specifications. The 825-P thermal element always operates in one of two modes: starting or running. In starting mode, the thermal element trips in Locked Rotor Time at Locked Rotor Current whether the motor is at ambient or at normal operating temperature.

Page 80: Star-Delta (Wye-Delta) Starting
In addition to enabling the Star-Delta, you must assign Star and Delta to Auxiliary output relays (one each). The 825-P issues the command to switch from Star to Delta (Wye to Delta) as soon as the starting current has dropped to the rated value and the motor has reached its normal speed in Star (Wye).
Page 81: Start Inhibit
PH REV. ENABLE Y, N The 825-P uses phase currents or phase voltages (if available) to determine that the phase rotation of signals applied to the relay matches the phase rotation setting. When you set Ph. Rev. Enable equal to Y, the relay trips 0.5 seconds after incorrect phase rotation signals are applied to the relay.

Off, 1.00…1.20 xVnm OV WARN DELAY 0.0…120.0 s When you connect the 825-P voltage inputs to phase-to-phase connected PTs, as in Figure 12, the relay provides two levels of phase-to-phase overvoltage and undervoltage elements. When you connect the 825-P voltage inputs to phase-to-neutral connected PTs, as in Figure 12, the relay provides two levels of phase-to-neutral overvoltage and undervoltage elements.

The setting range for Trip and Warn Levels shown in Table 33 are for Rated Freq. := 60 Hz. The setting ranges are “Off, 45.0–55.0 Hz” when Rated Freq. := 50 Hz. The 825-P provides two warning and two trip overfrequency or underfrequency elements with independent level and time-delay settings. When an element level setting is less than the Nominal Frequency setting, the element operates as an underfrequency element.

Chapter 7 Metering & Monitoring Motor Operating Statistics The 825-P retains useful machine operating statistics information regarding the protected motor. NOTE: While the relay power is off, the elapsed timers do not advance. If relay power is off for a significant amount of time, the elapsed calendar time does not match the elapsed time recorded by the relay.
Page 109: Analyzing Events
• Serialized Events Recording Event Summary Reports Each time the 825-P trips and in response to other selected conditions, it captures motor current and voltage (if included). This collection of data is called an event summary report. This section explains what causes the relay to save an event summary report, and what the event summary data means.

SER Triggering Recording (SER) Report The 825-P relay stores an entry in the SER report for a change of state of any one of the elements listed in Table 112 on page 235 and Table 113 on page 238. The relay saves up to 512 records in nonvolatile memory.

Vbc = 120 ∠+90 Periodic Tests (Routine Maintenance) Due to the 825-P being equipped with extensive self-tests, the most effective maintenance task is monitoring the front panel messages after a self-test failure. In addition, review each relay event report generated by a fault. Such reviews frequently reveal problems with equipment external to the relay, such as instrument transformers and control wiring.
