Commissioning, Startup, Operation, and Shutdown (Continued)Start the pumpCAUTION:• Immediately observe the pressure gauges. If discharge pressure is not quickly attained, stop the driver,reprime, and attempt to restart the pump.• Observe the pump for vibration levels, bearing temperature, and excessive noise. If normal levels areexceeded, shut down the pump and resolve the issue.Before you start the pump, you must perform these tasks:• Open the suction valve.• Open any recirculation or cooling lines.1. Fully close or partially open the discharge valve, depending on system conditions.2. Start the driver.3. Slowly open the discharge valve until the pump reaches the desired flow.4. Immediately check the pressure gauge to ensure that the pump quickly reaches the correct dischargepressure.5. If the pump fails to reach the correct pressure, perform these steps:a) Stop the driver.b) Prime the pump again.c) Restart the driver.6. Monitor the pump while it is operating:a) Check the pump for bearing temperature, excessive vibration, and noise.b) If the pump exceeds normal levels, then shut down the pump immediately and correct theproblem.A pump can exceed normal levels for several reasons. See Troubleshooting for information aboutpossible solutions to this problem.7. Repeat steps 5 and 6 until the pump runs properly.Activate the i-ALERT Condition MonitorWARNING:Never heat the condition monitor to temperatures in excess of 300°F (149°C). Heating to thesetemperatures could result in death or serious injury.CAUTION:Always wear protective gloves. The pump and condition monitor can be hot.NOTICE:Do not use the condition monitor in atmospheres containing acetic acid.The condition monitor is ready for activation when the pump is running and has reached a steady flow,pressure, and temperature. This process only takes a few minutes.Place a small magnet on the condition monitor over the ITT logo and then remove it, as this exampleshows.60 Model 3796 i-FRAME Installation, Operation, and Maintenance Manual
Commissioning, Startup, Operation, and Shutdown (Continued)Magnet761BWhen the condition monitor is activated it:1. Displays a series of red LEDs followed by a solid green LED.2. Collects eight samples that are spaced one second apart.3. Averages these readings to establish the baseline vibration level.4. Flashes a green LED after approximately twelve seconds.For the first ten minutes, the green LED flashes every second for five consecutive flashes and thenpauses to take a vibration reading. More frequent measurements (every six seconds) are taken in thisstartup period so that an alarm can be immediately detected.i-ALERT Condition Monitor routine operationMeasurement intervalThis table shows the measurement intervals for the condition monitor during normal operation and whenthe monitor is in alarm mode.ModeMeasurement intervalAlarm modeNormal operating modeAlarm modeMagnetic device considerationsFive minutesTwo minutesWhen the condition monitor measures a reading beyond the specified temperature and vibration limits, theappropriate red LED flashes. After the process or pump condition that causes the alarm is corrected, thecondition monitor returns to normal mode after one normal-level measurement.When the condition monitor is in alarm mode, you should investigate the cause of the condition and makenecessary corrections in a timely manner.Be careful when you use magnetic devices in close proximity of the condition monitor, such as magneticvibration-monitoring probes or dial indicators. These magnetic devices can accidentally activate ordeactivate the condition monitor resulting in improper alarm levels or loss of monitoring.Model 3796 i-FRAME Installation, Operation, and Maintenance Manual 61
