3 Fundamentals More than 500,000 Emotron monitors installed worldwide Emotron has been manufacturing Load Monitors longer than any other company 62% of Emotron’s Monitors are installed to Pumps The only monitor to measure shaft power (BHP) The only monitor to have automatic setup (AutoSet)

4 What is an M20?

5 To detect abnormal conditions here We measure “shaft power” here “An electronic system that monitors the Shaft HP of a motor and provides protection against abnormal process conditions - using the motor as a sensor” What is an M20?

6 How does the M20 measure Shaft HP? SHAFT POWER = POWER IN – POWER LOSSES MOTOR POWER IN MOTOR POWER LOSSES SHAFT POWER (HP)

7 Motor Losses Where do the losses come from and how big are they? Fan (Windage) Bearing friction Electrical losses Many motors are only 70 to 80% efficient due to these losses. Magnetic losses The M20 continually calculates these losses and subtracts them from the measured motor input power.

8 Benefits of measuring Shaft HP? Manufacturers typically express load data in BHP not Input Power, e.g., Pump Curve The varying losses of the motor are discounted Improved accuracy & reliability Protection parameters are set against the working load only The HP displayed is the ‘actual’ HP required by the application The displayed BHP can be useful when looking at the pump curve

9 Other features – Displayed Data Window 01 – Motor Load Either: HP HP% kW kW% Window 02 – Motor Supply Voltage Window 03 – Motor Operating Amps Window 04 – Locks all settings

10 Other features – Analog Output Can be set for either: 0-20 mA 4-20 mA 20-0 mA 20-4 mA

11 Competing technologies

12 Examples of technologies available to measure Motor Load Integra Motor Minder Unipower HPL 420 Load Controls PMP-25

13 Current Monitoring (Integra) AMPS LOAD 60-70% Pro’s Simple Low Cost Con’s Only Effective if Motor is Loaded at 70-80% Better for Overload than Underload

14 Motor Input Power Monitoring AMPS VOLTS POWER LOAD Pro’s Accurate measurement of load to motor Detects Overload and Underload Works well on lightly loaded motors Con’s Does not consider motor losses Does not determine actual BHP Load Controls is mounted externally and can lead to unintended tampering

15 M20’s key features  Shaft power measurement*  Four levels of protection*  Autoset*  Derives supply from Line Voltage*  Electronic locking of parameters*  Smallest footprint of any power monitor available*  Readout of HP, %HP, kW, %kW, Volts and Amps*  Programmable relay configurations  Just three models cover all motor voltages up to 690 VAC  Medium voltage (up to 6900V) applications with special Transformer*  Programmable analogue signal proportional to the motors shaft power*  Motors up to 800 HP can be monitored  Remote Reset / AutoSet / Pre-Alarm blocking input * * Unique features

16 Reliable and simple protection of a Mag Drive Pump Shaft Power Time 90% 74% Response Delay

17 Examples of abnormal pumping conditions detected by M20 Closed suction valve – Underload Dry running – Underload (or overload)* Dead Heading – Underload (or overload)* Cavitation – Underload & Overload Blocked impeller – Overload Bad Bearings – Overload Worn Impeller – Underload Plugged Filter – Underload (or overload)* * Pump specific

18 Typical pump types that can be monitored Mag Drive Centrifugal Progressive Cavity Gear (Positive Displacement) Centrifugal Mag Drive Lobe

19 How to determine Part Numbers

20 M20 … There are just three M20 models to choose from …… Description / Motor Supply VoltagePart Number M20 / 1 x 100-240 and 3 x 100-240 VAC01-2520-20 M20 / 3 x 380-500 VAC01-2520-40 M20 / 3 x 525-690 VAC01-2520-50

21 Current Transducers … There are just four CT’s to choose from …… Motor FLACTM 010CTM 025CTM 050CTM 100 0.1 – 10 AmpsX 10.1 – 25 AmpsX 25.1 – 50 AmpsX 50.1 – 100 AmpsX For applications that are greater than 100 Amps FLA, please contact H2flow Controls

22 M20 - Mounting options NEMA 4X Enclosure Note: When the M20 is installed in the NEMA 4X enclosure, the Current Transducer cannot be installed more than 6 cable feet from it

23 M20 - Mounting options Panel Mount Kit

24 M20 electrical installation Current Transformer L1 L2 L3 91113 1 2 6 M 3 ~ 34 % 01 35 7 8 5 Control Voltage common START K1 Auxiliary Contact STOP K1 (Motor Starter) Control Voltage R1 (terminal 7) = Main alarm for overload and / or underload R2 (terminal 8) = Pre-Alarm for overload and / or underload Pre-Alarm Remote Reset / AutoSet Analogue output: 4 - 20 mA 20 – 4 mA 0 – 20 mA 20 – 0 mA (Programmable)

25 Setting up a M20 ….

26 M20 - Set up 1.Set the unit of measurement (HP, HP%, kW or kW%) 2.Set the M20’s function 3.Program the motor HP and Full Load amps 4.Set the motor start delay 5.Set the trip response delay 6.Set the M20 for single or 3 phase operation 7.Set up the relay logic 8.Start the pump and apply normal load 9.Press Autoset 10.Adjust trip points manually if required

27 Step 1. - Set the unit of measurement: Options: HP %HP kW %kW Press these two buttons simultaneously until the desired unit of measurement is displayed. HP % Reset + Next Enter AutoS et

28 Step 2. - Set the M20’s function: Options: Overload with Pre-Alarm Underload with Pre-Alarm Overload & Underload with Pre-Alarm Note: For most Centrifugal Pumps, it is best to set the M20 for ‘Underload with Pre-Alarm’ 05 In Window 05, select the monitors function : Overload with Pre-AlarmOverload & Underload With Pre-Alarms Underload with Pre-Alarm

29 Step 3. - Set the Motor’s HP rating: From the motors nameplate, set in Window 41 - the motors HP rating 41 5.0

30 Step 4. - Set the Motor’s Full Load Current: From the motor’s nameplate, set in Window 42 - the motors Full Load Current 42 6.5

31 Step 5. - Set the Motor Start Delay timer: In Window 31, set the motors start delay timer: (adjustable from 1 to 999 seconds) 31 2.0

32 Step 6a. - Set the Min Alarm Response Delay timer: In Window 34, set the Min Alarm Response delay timer: (adjustable from 0.1 to 90 seconds). Once the load drops below the alarm set point, this timer will start. At the end of the delay, the M20’s main alarm relay will trip. For most Mag Drive Centrifugal Pumps, a time of 2 to 3 seconds is reasonable. 34 3.0 Alarm level (Window 14) Min Alarm Response Delay (34) Alarm

33 Step 6b. - Set the Max Alarm Response Delay timer: In Window 32, set the Min Alarm Response delay timer: (adjustable from 0.1 to 90 seconds). Once the load drops below the alarm set point, this timer will start. At the end of the delay, the M20’s main alarm relay will trip. For most Mag Drive Centrifugal Pumps, a time of 2 to 3 seconds is reasonable. 32 3.0 Alarm level (11) Max Alarm Response Delay ( 32) Alarm

34 Step 7. - Set M20 for Single or Three Phase Motor Supply: In Window 43, set the M20 to operate on either a single or 3 phase supply 43 3 PH

35 Step 8a. - Set the R1 to Latched or Unlatched: In Window 61, set R1 to either Latched (ON) unlatched (OFF). For most control wiring configurations, this should be set to (ON). 61 ON

36 Step 8b. - Set the Relay configuration (R1): In Window 63, set R1 to either normally open (NO) or normally closed (NC). 63 NC

37 Step 8c. - Set the Relay configuration (R2): In Window 64, set R2 to either normally open (NO) or normally closed (NC) 64 NC

38 Step 9. - Activate the AutoSet procedure: a) Start the pump b) Run the Pump with all valves open and the in a ‘normal’ condition. Press the AutoSet key for 3-seconds until the word Set appears in the display

39 Step 10. - Manually adjust Alarm set points if necessary: a) Create an “abnormal” condition, e.g., close a suction valve and confirm an underload alarm is activated. b) If necessary, manually adjust the Alarm levels. Window 14 is the Main Underload Alarm level. Window 13 is the Pre-Alarm Underload level.

40 Summary

41 M20 Limitations Application must be driven by an AC Induction Motor Monitoring VFD driven applications must be viewed with care Motors larger than 800 HP cannot be monitored A M20 must be used for each motor M20 must be installed within 6 feet of Current Transducer
