8-5 User Screen - Bottom Right

Option: Function:

Mains Frequency The average frequency measured on three

phases.

Motor kW The motor's running power in kilowatts.

Motor HP The motor's running power in horsepower.

Motor Temp The motor's temperature, calculated by the

thermal model.

kWh The number of kilowatt hours the motor has

run via the soft starter.

Hours Run The number of hours the motor has run via the

soft starter.

7.11.2 Performance Graphs

The loggings menu allows the user to view performance

information in real-time graphs.

The newest information is displayed at the right hand edge

of the screen. The graph can be paused to analyse data by

pressing and holding the OK button. To re-start the graph,

press and hold OK.

8-6 Graph Timebase

Option: Function:

Sets the graph time scale. The graph will progres-

sively replace the old data with new data.

8-7 Graph Maximum Adjustment

Range: Function:

400%* [0% - 600%] Adjusts the upper limit of the performance

graph

8-8 Graph Minimum Adjustment

Range: Function:

0%* [0% - 600%] Adjusts the lower limit of the performance

graph.

8-9 Mains Reference Voltage

Range: Function:

400 V* [100 - 690

Sets the nominal voltage for the LCP's

monitoring functions. This is used to

calculate motor kilowatts and kilovolt

amperes (kVA), but does not affect the MCD

500's motor control protection.

Enter the measured mains voltage.

7.12 Restricted Parameters

15-1 Access Code

Range: Function:

0000* [0000 -

9999]

Sets the access code to enter the simulation tools

and counter resets or the restricted section of the

Programming Menu (parameter group 15 and

higher).

Use the B

BACK

and O

buttons to select which

digit to alter and use the

Ⴃ

and

Ⴍ

buttons to

change the value.

NOTE

In the event of a lost access code, contact

your supplier for master access code that

allows you to re-

program a new access

code.

15-2 Adjustment Lock

Option: Function:

Selects whether the LCP will allow parameters to be

changed via the Programming Menu.

Read &

Write

Allows users to alter parameter values in the

Programming Menu

Read Only Prevents users altering parameter values in the

Programming Menu. Parameter values can still be

viewed.

No Access Prevents users adjusting parameters in the

Programming Menu unless an access code is

entered.

NOTE

Changes to the Adjustment Lock setting take

effect only after the Programming Menu has

been closed.

15-3 Emergency Run

Option: Function:

Selects whether the soft starter will permit emergency run

operation. In emergency run, the soft starter will start (if

not already running) and continue to operate until

emergency run ends, ignoring stop commands and trips.

Emergency run is controlled using a programmable input.

When Emergency Run is activated in internally bypassed

models which are not running, the starter will attempt a

normal start while ignoring all trips. If a normal start is not

possible, a DOL start via the internal bypass relays will be

attempted. For non-bypassed models, an external

emergency run bypass contactor may be used.

15-4 Current Calibration

Range: Function:

100%* [85%

115%]

Motor Current Calibration calibrates the soft

starter's current monitoring circuits to match an

external current metering device.

Use the following formula to determine the

necessary adjustment:
