PowerTalk values
This information can be used to analyze the status of the system and the battery.
I System
Available on all systems
Relais
Vmotion status
Vmotion is the power circuit for the drive controller. This circuit can be switched off by a relais on the main controller and by the emergency stop, thus disabling drive functionality. The relais is switched in various situations:
- When the emergency stop is pushed (reversed by pressing on/off)
- When the system switches to energy save mode (reversed by pressing a button or the pushbar)
- When the system is connected to a charger (reverssed by disconnecting the charger)
- When the immoblizer is activated (reversed by de-activation of the immobilizer)
While the system is connected to USB the relais is not switched for energy save mode, immobilizer or charging, thus maintaining functionality for testing and troubleshooting.
Vmotion status 0: circuit switched off (Drive functionality off)
Vmotion status 1: circuit switched on
Power supply
5V
The 5V power circuit is used to power the User Interface and force sensors. Typical value is stable on approx. 5V.
12V
The 12V power circuit is used to power the emergency switch circuit and additional inputs and outputs like LED’s and switches. typical value is stable on approx. 12V.
24V
This value shows the voltage of the 24V power circuit on the main controller. Typical value is approx. 0.5V below Vmotion.
Vmotion
This is the power circuit for the drive controller. See also Vmotion status. The value is highly dependent on battery voltage. On a full esense battery, the value is typically in range of 26V, on a low battery the value is typically slightly below 24V. When the Drivewheel or additional actuators are moving and draw high currents the voltage typically drops by up to 2 – 2.5 Volts.
NOTE: When Vmotion drops below 21V the system becomes unstable and switches to service mode. This is typically logged as ‘BLDC undervoltage’ in the system log file.
Dipswitch
Hardware dipswitch
The hardware dipswitch is a 16-position switch on the main controller that defines the system type. Numbers 1 up to 14 define system types like e.g. first generation esense systems or patient lifts. Switch setting 15 enables the use of software dipswitches (see “Software dipswitch”). This is the standard setting for esense Controller boxes.
Software dipswitch
When the hardware dipswitch is set on 15, the software dipswitch defines the system type. Software dipswitches can be set by Level 3 and 4 licensed users only (via “System > Set system type..”).
I Pushbar
Available on all systems
S1/S2 signal
Status
The number shows the status of the sensor.
0: disabled
1: initializing (calibrating, defining its signal at rest)
2: released
3: pushed
4: error (service mode)
For standard esense systems the status for S1 and S2 is always equal. Therefore, the disabled state is only showed when both sensors are switched off.
Init value
This value shows the sensor value registered at calibration. For standard esense systems this value must be between 400 and 550. In case calibration was unsuccessful this is shown by a “-“.
Raw value
This value represents the real-time sensor value.
Delta
This value represents the difference between the Init and Raw value. Delta is used to calculate the level of drive support; a higher value leads to a higher torque and speed of the drive wheel. This value can only be calculated when an Init value is available (after successful calibration).
STD
This value is a measure for the stability of the sensor signal.
A high STD is an indication of a sensor being pushed manually.
A very low (close to zero) STD is an indication of a sensor being in rest, broken or mechanically clamped.
The value is constantly monitored for safety reasons and plays an important role in detection of sensor offset and cable break faults.
NOTE: For additional information see PowerTalk settings – pushbar.
I Interface (UI 2)
Available on systems with User Interface 2 (esense)
Emergency switch
Status
This value shows the status of the emergency switch.
0: emergency switch inactive
1: emergency switch pushed
The status remains pushed until the system is activated again. The system is unlocked by turning the emergency switch back to its original position and shortly pushing the on/off button.
Foil
Button status
This value shows a 16-digit binary code. Each position represents a button on the interface foil. For standard (5 button) esense systems only the left 5 positions are used. A ‘1’ is displayed when a button is pushed, a ‘0’ is displayed when the button is released.
0: button released
1: button pressed
NOTE: This information can be used for troubleshooting. When none of the digits jump from 0 to 1 if a button is pushed, it most likely concerns a user interface foil fault, requiring foil replacement.
LED status
This value shows a 16-digit binary code. Each position represents a LED on the interface foil. Orange/green 2-colour LED’s have two positions. For standard esense systems only the left 12 positions are used.
0: LED switched off
1: LED intended to be lit
NOTE: This information can be used for troubleshooting by comparing the number of 1 digits in the binary code with the number of LED’s lit. If the number of digits is higher than the number of LED’s actually lit, it most likely concerns a user interface foil fault, requiring foil replacement.
Tilt sensor
Transversal plane angle
This value shows the angle of the tilt sensor in the esense UI 2 controller. In standard esense systems this measurement has no further functionality.
Keylock
Magnet status
The keylock can be triggered by placing a magnet on the lock icon (left to the on/off button on the esense interface). This value shows the status of the magnet sensor.
0: no magnet detected
1: magnet detected
NOTE: When no magnet is detected, this can either be caused by magnet not being strong enough or by the magnet detection sensor inside the interface. For troubleshooting always try to activate the function with a strong and trusted magnet first.
Lock status
This value shows the status of the system lock. The lock can be deactivated with a magnet or by pushing a button on the user interface.
0: lock inactive
1: lock active
NOTE: Lock functionality can be switched on in the lock activation settings.
Immobilizer
Status
The immobilizer is a switch that can be added to the esense Controller Box. Activating the immobilizer switches off all drive functionality.
0: immobilizer switched off
1: immobilizer switched on
NOTE: Activation of the immobilizer can be toggled in the immobilizer polarity settings.
I Interface (PA-S)
Available on systems with stainless steel User Interface (PA-S)
Emergency switch
Status
This value shows the status of the emergency switch. The status remains pushed until the system is activated again by unlocking the emergency switch and shortly pushing the on/off button.
0: emergency switch inactive
1: emergency switch pushed (active)
Activation status
Toggle switch
This value shows the status of the toggle switch for sideways driving on PA-S 360 and E1409-9060 systems. Values have the following meaning:
0: neutral
1: right
2: left
NOTE: This information can be used for troubleshooting by checking the value shown when the switch is pushed in right or left direction. If the number does not change when the switch is pushed, it most likely concerns a user interface panel fault, requiring panel replacement. The panel may be returned to the manufacturer for repair.
Indication LED
This value shows a 16-digit binary code. Each position represents a LED on the interface foil. Orange/green 2-colour LED’s have two positions. For standard esense systems only the left 12 positions are used.
0: LED switched off
1: LED intended to be lit
NOTE: This information can be used for troubleshooting by comparing the number with the number of LED’s actually lit. If there is a deviation from the actual status, it most likely concerns a user interface fault, requiring panel replacement. The panel may be returned to the manufacturer for repair.
Immobilizer
Status
The immobilizer is a switch that can be added to the esense Controller Box. Activating the immobilizer switches off all drive functionality.
0: immobilizer switched off
1: immobilizer switched on
NOTE: Activation of the immobilizer can be toggled in the immobilizer polarity settings.
I Drive
Available on all systems
Torque
Current torque
This value shows the real-time torque of the Drivewheel on a scale of 0 (0 torque) to 4000 (max torque).
NOTE: Torque in forward direction is negative (-), torque in backwards direction is positive.
Speed
Vehicle speed
This value shows the real-time speed of the Drivewheel on a scale of 0 (0 speed) to 6000 (max assisted speed).
NOTE: Speed in forward direction is negative (-), speed in backwards direction is positive.
Example: To calculate the speed in m/h the displayed value shall be multiplied by 1.2. For instance, a speed value of 3000 translates to 3600 m/h (3.6 km/h).
I Side drive
Available on all 360 systems
Rotation status
Status
This value shows the status of the steer mechanism in a number, with following meaning:
0: disabled
1: initializing
2: off
3: standing still
4: rotating to the right
5: rotating to the left
6: mechanism error
Rotation PWM
This value shows the power to the steer motor. It is generally not used for troubleshooting or analysis.
Position
This value shows the real-time direction of the Drivewheel. Both the left and right side 90-degree segment are divided in 63 positions.
NOTE: A positive value indicates a position in the left segment, a negative value indicates a position in the right side segment.
Position switch
The steer mechanism has three magnets that define the forward and both (left and right) 90-degree sideways directions. This value shows when the magnets are detected:
0: magnet not detected
1: magnet detected
NOTE: Both in the 90 degree sideways positions and the forwards direction the value must be “1”.
I Battery
Available on all systems with battery pack
Info
Last 10 cutoff reasons
This value functions as a log for cut-off of the battery. In these situations, power from the battery is temporarily switched off by the battery electronics due to an unusual and potentially harmful event. The log fills from right to left; so the most right number is the latest event. Values have the following meaning:
1: battery voltage too low
2: discharge current too high
3: battery temperature too high
4: charge voltage too high
5: charge current too high
Typically, the battery power remains switched off until the cause of cutoff is solved. For example, this solution may be recharging the battery (cause 1), cooling the battery over time (cause 3) or disconnecting the charger (cause 4 and 5).
Battery current
Battery current
This value shows the current to and from the battery. Due to slow communication between the battery and the esense main controller the value is displayed with delay and is not refreshed in a fast rate.
NOTE: A positive value indicates charging of the battery, a negative value indicates discharging.
Absolute remaining capacity
This value shows the capacity in mAh that is still available in the battery.
Relative remaining capacity
This value shows the capacity that is still available in the battery as a percentage of the full battery capacity.
Battery voltage
Battery voltage
This value shows the voltage of the battery. Due to slow communication between the battery and the esense main controller the value is displayed with delay and is not refreshed in a fast rate. Therefore, for general monitoring the voltage values under System are more relevant.
Battery temperature
Battery temperature
This value shows the real-time battery temperature, measured in degrees Kelvin.
NOTE: The temperature in degrees Celsius is the displayed value minus 273 (300 degrees Kelvin equals 27 degrees Celsius).
