2 Introduction 2.1 Overview The Powell Motor Manager 6 (MM6) is an intelligent relay used to monitor a three-phase motor and provide control, protection and fast communications. The device provides motor data (measured and calculated) in text message format on a colour Liquid Crystal Display (LCD). Several configurations of modules are possible to facilitate a variety of functionalities from entry level (SCM + conventional overload) to a complete control, protection and monitoring package with colour display (SCM+PMM+DCM). The modules are interconnected via CAN bus, which provides a high-speed link for exchanging information between modules. All modules are designed to operate in an ambient air temperature of 5 DegC to +75 DegC, relative humidity 95% non-condensing. The SCM is the data concentrator providing sufficient digital I/O for starter control in addition to an EIA485 Modbus RTU serial port for external communications. Optional ports are available for DeviceNet or Profibus DP in addition to the standard EIA485 Modbus RTU interface. Time synchronization is provided via the Modbus serial interface to a resolution of 1mS. This value is used for event time stamping and storage in the historical log. The SCM provides optional under voltage restart and control for DOL, DOLR, Two-speed, Star Delta, VSD, Soft Starters and pulsed devices such as latched contactors. The OCM and DIM are expansion modules typically used to replace push buttons and relays whilst utilising electronic or conventional protection. The DCM is based around a colour LCD graphical user interface that allows the user to monitor, control and configure the Motor Manager 6. The PMM is a standalone measurement and control module that samples CT/VT inputs and uses thermal modelling techniques to provide accurate motor protection. The SCM, OCM and DCM have inbuilt temperature sensors so the starter and switchroom temperatures can be monitored. The BTM and RTM are expansion modules used for temperature measurement of the system. The module selected depends on the application. Cuckoo mode is a Communication mode that allows data mapping emulation of legacy product (MM5, MM3, MM2, MM1).

3.1.3 Protection and Metering Module (PMM) The PMM is a standalone current and voltage protection module for the MM6. It monitors current and voltage and uses this data to calculate information required to protect the motor. There are 2 PMM types; one for star configuration and one for delta configuration. The star PMM can be connected in either the star or delta configuration and the delta PMM can only be configured in the delta configuration (see section 5.4.2 for details). The relay output can be wired in series with the contactor output on the SCM as a backup trip mechanism in the unlikely event of a CAN bus fault. An optional NTC/PTC Thermistor input is provided.

3.2 CT Modules The interface to the primary conductors is via a 3 phase CT Module, which provides a signal conditioning interface and isolation. This interface can be quickly disconnected from the PMM module so the electronics can be exchanged with minimal disruption to chassis wiring. Two CT Modules are provided:
1. The PT-CTM allows the primary conductors to pass-through three embedded CTs when the FLC is =>0.5A and =<15A.
Ratio: 15 / 0.026 A
Class: 5P8
Note: The peak measurement current of the PT CTM is 176A. If an overload multiplier of x8 is applied the PT CTM could be used on systems with a rated FLC of 22A. Whilst not part of the recommended system design; edge cases might take advantage of this. Please contact Powell UK regarding this type of application.
2. The 1A-CTM provides 3 x 1A inputs for external CTs to be used when the rated FLC of the motor is >15A. Standard encapsulated blocks are available for this purpose (see CT Block below).
Ratio: 1 / 0.0083 A
Class: 10P25
3.2.1 CT Block (3 phase) The 3-phase CT block is fitted to starters with rated Full Load Current greater than 15A and up to 120A. Ratios of 30/1, 60/1 and 120/1 are available and are connected to the 1A-CTM using a pre-made cable. Above 120A FLC standard foot mounted CTs are used. Individual S1 and S2 CT secondary connections per phase are connected, via 2.5mm2 cable, to the 1A CTM Phoenix terminals (see above and Figure 22 on page 55). In addition to the pictured CT, MM5 Euro and Slim-line packages are also available for 60/1 and 120/1 ratios. These were made available for the replacement of legacy product.

5.2 Mounting The MM6 can be mounted in any orientation; however, it is designed to operate in the horizontal position with the SCM RJ12 connector at the top i.e. the orientation obtained when a directly connected, door mounted, DCM has the operator keypad to the right. If any other orientation is required please contact Powell. An unobstructed clearance of at least 25 mm is required at the rear of the SCM for cable connections. This required clearance increases to 65 mm at the rear of the PMM to allow CT modules to be fitted. The Display & Control Module (DCM) or Operator Control Module (OCM) is installed through the compartment door or chassis front. If mounted on a hinged door ensure that cables cannot be trapped in the lip or seal of the door. Where the SCM is to be attached directly to a DCM or OCM through a cut-out in a plate, the plate material thickness must be 2mm (+0.3mm, -0.0mm) for the gasket to seal correctly. Tolerances to be +/-0.5mm except where otherwise stated.
1. The mounting cut-outs are shown below.
87mm
Figure 12 Door cut-out dimension details
2. Ensure that all burrs/sharp edges are removed from the cut-out.
3. Before inserting the DCM or OCM into the cut-out ensure the gasket is correctly fitted to the rear of the DCM / OCM.
4. If the SCM is to be mounted directly on the rear of the DCM or OCM then push this into position
making sure that the internal plug and socket are correctly aligned.
5. Connect the required electrical cables/supplies; refer to 5.4. For further assembly instructions, please refer to Section 5.3 Mechanical Assembly and 5.4 Electrical Connections.
5.2.1 DIN Rail Mounting The SCM, PMM & EXM modules can be fitted to a DIN rail by fitting the DIN rail adaptor to the backplate. The backplate must be carefully removed from the module, ensuring that the circuit boards within the module are not dislodged. Attach the adaptor to the backplate and refit the backplate to the module.

Please note that it is only possible to connect 1 of each type of expansion module to a single MM6. 5.4.10 Earthing The earthing arrangements outlined below should be followed for optimum performance:
1. All earth points in a chassis should be connected to a single stud
2. All earth cables should be as short as possible
3. The metalwork that the MM6 DCM is installed into must be securely earthed. We recommend the use of a braid.
The following is recommended for the communications wiring:
1. The serial link screen should only be earthed at one point in the entire installation. Extra care should be taken to avoid multiple earth points when extension tiers are added to existing installations.
2. The MM6 shield terminal must be connected to the cable screen.
3. The screen must be continuous, even through junction boxes. Care must be taken to ensure it is only earthed at the common point. Bare wires must be kept to a minimum length and screen wire should be sheathed.
Page 62 of 273
5.4.11 CT / VT Correct polarity is essential otherwise the power readings will be incorrect. 5.4.12 Cables Note: All cables must have ferrules fitted and only one cable per terminal is preferred to reduce PCB stress. 5.4.12.1 Mechanical Stress Care must be taken to avoid the circuit board being put under stress due to over tight looms. Although the unit will initially operate, experience has shown the connectors will work loose and the PCB may develop miniature cracks and fail prematurely. The wiring loom should be located above the MM6 so it doesnt strain the PCBs, however, ensure sufficient
space is left so access to the clips is possible. 5.4.12.2 Power and Control cables Power and control cables should be segregated from each other to avoid cross talk and must not run parallel to each other for long distances. Obviously this is not always possible, however, they must not be placed in the same trunking or tie-wrapped together. When routing power cables inside the chassis or cabinet, keep them as short as possible and position them as close to the reference ground (starter walls) as possible to limit air borne noise transmission. Do not allow power cables to touch the MM6 plastic case. Control cables should be minimum 0.5mm sq and maximum 2.5mm sq. 5.4.12.3 Serial link cabling Serial link cabling internal to panel must be Belden 3105A or EIA485 equivalent with characteristic impedance of 120 ohms. Serial link cabling external to panel must be armoured Belden 3105A or EIA485 equivalent with characteristic impedance of 120 ohms. Serial link cabling must not run parallel to any control or power cable and should be earthed outside the starter. The screen for the whole of an individual serial link must be continuous and only earthed in one place (see 5.4.10).
Particular care must be taken to avoid knicking the inner core insulation when stripping the outer insulation and screen from comms cable. This is a common cause of comms reliability problems.
5.4.12.4 Expansion Modules The expansion modules are connected via a pre-made CAN bus cable. Please note that only one expansion module of each type can be used with one MM6 up to a total of 3 modules. 5.4.12.5 Analogue I/O / RTD Always match the cable type inside the MCC with the field cabling to avoid impedance matching problems and do not route close to power or control cables.

6.1 Windows 6.1.1 Main viewing window The main viewing window allows the user to monitor and configure the MM6 and associated ancillary equipment. On power up the system will display the main screen, this allows access to the: DATA; SETTINGS; DIAGNOSTICS menus and the CONTROL window. 6.1.2 Softkey window The softkey window is a multi-function display that informs the user what function will be activated when the associated key is pressed (refer to Softkeys), such as start forward, reverse, reset trip etc. 6.1.3 Control mode & Login level window The upper part of the Control mode window informs the user which point, or points, of control is/are currently available. The lower part of the window shows the current login level (0-3) and the padlock icon. This padlock icon indicates setpoint editing is inhibited (login level 0). When the padlock is replaced by a key (login level 1-3) the setpoints can be edited. If no key is pressed for 5 minutes the user is logged out and the login level reverts to 0. T indicates that the drive is in Test Mode. 6.1.4 Zoom and Default Page If the rotary selector is pressed whilst on a data page item that is displayed in percent, amps, volts or hertz the item is then zoomed in on and occupies the whole of the display area. This zoomed in view can be exited by pressing the ESC or HOME keys. Any DCM that experiences a period of inactivity for ten minutes or more will automatically display a zoomed in item, this is known as the Default Page. Initially this page is configured to display the Motor Load. To set a new Default Page, zoom into the item as detailed above, log into level 1 or greater, and press the rotary selector a Flash message should appear on the display informing the user that a new Default Page has been set.

HOME The HOME key returns the user to the main screen with the DATA index selected.
ESC The ESC key is used to escape from a menu or to abort a setpoint change.
STOP This button is used to stop the drive. Note: This is not latched, but the MM6 can be
configured to trip when this button is pressed
Rotary Selector The rotary selector is used to navigate the menu structure. Counter-
clockwise/Clockwise rotation corresponds to up/down on menus and data forms. When the end of the selector is pressed the currently highlighted option is selected.
6.3 Softkeys The Softkeys are multi-function keys displayed at the right hand side of the screen, as shown in Figure 25. The function of each button will depend upon the currently selected mode and state of the MM6 e.g. if the drive is tripped then the function of the top softkey is Reset. If the trip is lockout trip the function of the
bottom softkey is Lockout Reset. See below for full details of all the options for the softkeys depending on the state of the feeder and the menus being viewed. Please Note: Following operation of the Reset or Lockout Reset keys, the normal function of the softkey is disabled for
1 second. This is to avoid the risk of multiple pushes of the softkey causing both a reset and a start. The wording on the Softkey will be in white if the indicated function is available and in grey if the function is not available e.g. START appears in grey if the drive is tripped because the start cannot be performed until the trip has been reset.

Softkey Name Context Description
The drive is tripped and a Lockout Reset is required
Press to reset a lockout trip condition (Earth Fault, Stalled Rotor or, in extreme circumstances, Overload which has not cooled down yet).
A Lockout Reset is always required after clearing the cause of an Earth Fault or Stalled Rotor trip.
It can also be used to reset an Overload Trip before the motor has cooled, if necessary, but there is then a danger of damaging the motor as the mathematical thermal capacity model will no longer agree with the true condition of the motor. The correct procedure is to wait until the motor has cooled down and the Overload trip will then reset using the normal Reset command.
FINE A numeric setpoint is being adjusted Press to set the Rotary selector increment to 1.
6.3.3 LEDs Four LEDs are incorporated into the lower front section of the DCM and these provide visual indication of MM6/Motor state:
State Description
Running (Red / Green or flashing) Indicates that the motor is running (Set colour in Factory setup).
Stopped (Red or Green) Indicates that the motor is stopped (Set colour in Factory setup).
Alarm (Amber) Indicates the presence of an activated alarm. The cause of the alarm is shown on the DT1: motor status and DG1: diagnostics pages.
Tripped (Amber or Flashing Amber)
Indicates the presence of a Trip action taken by Motor Manager. The
cause of the trip is shown on the DT1: motor status and DG2: diagnostics pages.
Abnormal situations
The running LED will flash if an abnormal running situation is present:
1. The contactor is closed but the Motor State is not Running (i.e. Stopped or Accelerating)
2. The contactor is open but the Motor Load % is greater than the minimum cut off.
The minimum cut-off for the above comparison defaults to 5%, but can be changed in the factory set-up ST5 PMM Acceleration Level. This value is also used by the PMM to decide when to start timing the acceleration period.

6.5 Data Menu The Data menu allows the user to interrogate the MM6. This allows the user to see data such as: current status, active alarms and trips, the state of its digital inputs, the Event History etc. The user can select between a digital and analogue view in order to display the available data. This is a selection that can be made in ST5: Factory by setting Default Page Type to either Digital or Analogue. The following sections detail the information displayed in each view. 6.5.1 Digital The digital view of actual I1 current shown below simply displays the actual current.
Figure 30 Digital Display Example
6.5.2 Analogue The analogue view of actual I1 current displays the actual current in the bottom right hand corner of the screen. In addition to this, information colour coding is used to indicate alarm and trip ranges that relate to setpoint values previously configured by the user. The colour codes are as follows: Yellow = Alarm Range Green = Normal Operating Range Red = Trip Range

6.5.3 Error Messages The following screens indicate that there is a problem with the data being displayed. U/R indicates that the value is Under Range, which means that it is below the minimum value that can be displayed on the simulated analogue display as per the device configuration.
Figure 32 Under Range Indication
O/R indicates that the value is Over Range, which means that it is above the maximum value that can be displayed on the simulated analogue display as per the device configuration.
Figure 33 Over Range Indication
ERR (displayed similarly to the above error messages) indicates that the MM6 has experienced difficulties calculating an accurate figure to be displayed on the analogue display. If this problem is witnessed, please make a note of the error, the page on which occurs and contact Powell.

6.6 Settings Menu The Settings menu allows the user to configure the MM6. The user must enter a password, or energise the Setpoint Input (if configured), before the Motor Manager will allow setpoints to be changed,. Please refer to Sections 6.6.1 and 8.1.2.

6.6.1 Changing Setpoints Some setpoints are only applicable if other setpoints are set to specific values e.g. High Speed FLC only
applies if the Starter Type is set to Two Speed. In these cases the dependent setpoints will not be visible
on the MM6 display until the independent setpoint is set to the appropriate value. It is therefore necessary to set the Starter Type setpoint before making other settings in this section. 6.6.1.1 Logging In The MM6 will not allow the operator to change any setpoint values without first logging i
