20 ME00070B TMS7 SERIES
7. Current Imbalance Sensitivity
Range: 1 – 10
1 = Highest sensitivity (lowest imbalance)
I
5 = Average sensitivity
I
10 = Lowest sensitivity (highest imbalance)
Default Setting: 5
Description: Sets the sensitivity of the current imbalance
protection.
Adjustment: The factory setting is suitable for most applications
however the sensitivity can be adjusted to accommodate site
specific tolerances
8. Undercurrent Protection
Range: 15% – 100% FLC
Default Setting: 20% FLC
Description: Sets the trip point for the TMS7 undercurrent
protection as a percentage of motor full load current.
Adjustment: Set to a level below the motors normal working
range and above the motor’s magnetising (no load) current.
To disable the undercurrent protection make a setting less than
the magnetising current of the motor, typically 25% - 35% of
rated Full Load Current.
CAUTION
NOTE:
Undercurrent protection is only operative during
‘run’.
9. Stall Protection
Range: 80% – 550% FLC
Default Setting: 400% FLC
Description: Sets the trip point for the TMS7 stall protection as
a percentage of motor full load current.
Adjustment: Set as required.
CAUTION
NOTE:
Stall protection is operative only during ‘run’.
10. Soft Stop Mode
Range: 0 – 1
0 = Standard soft stop
1 = Pump control
Default Setting: 0 (Standard soft stop)
Description: Sets the active soft stop mode.
Adjustment: The standard soft stop mode automatically
monitors motor deceleration and will provide optimum control for
most applications. Pump control may however offer superior
performance in some applications and can be of particular
benefit in some pumping applications.
20. Local/Remote Operation
Range: 0 – 3
0 = TMS7 Local/Remote push button always enabled.
1 = TMS7 Local/Remote push button disabled while motor
running.
2 = Local control only. (TMS7 push buttons enabled, remote
inputs disabled)
3 = Remote control only. (TMS7 push buttons disabled, remote
inputs enabled)
Default Setting: 0 (Local/Remote button enabled)
Description: Enables and disables the local push buttons and
remote control inputs. Also determines when and if the
Local/Remote push button can be used to switch between local
and remote control.
Adjustment: Set as required
21. Relay Output A Functionality
Range: 0 –11
0 = Tripped
1 = Overcurrent trip
2 = Undercurrent trip
3 = Motor thermistor trip
4 = Starter overtemperature trip
5 = Phase imbalance trip
6 = Electronic shearpin trip
7 = Low current alarm
8 = High current alarm
9 = Motor overload alarm
10 = Start/Run
11 = Main contactor.

22. Relay Output B Functionality
Range: 0 - 11
Default Setting: 10 (Start/Run)
Description: Assigns the functionality of programmable relay
output B.
Adjustment: Refer Function 21 Relay Output A Functionality for
adjustment detail.
23. Relay Output C Functionality
Range: 0 - 11
Default Setting: 0 (Tripped)
Description: Assigns the functionality of programmable relay
output C.
