Firmware build date

The time and date that the system software for the main controller was created. This parameter is set by the software engineer at Indes.

Service ID

Identification ID of the esense system. The parameter is set during production at Indes. A removable sticker with this number is available on the esense Controller box.

NOTE: It is advised to place this sticker in a logical place on the outside of the product the esense system is integrated on. This makes linking of PowerTalk reports to products in the field easy.

Product type [L3]

A description of the type of product that the esense system is integrated on (e.g. “Line+ patient lift” or “M3050-R Equipment trolley”).

NOTE: This parameter can be set by the system integrator during installation.

Product serial [L3]

The serial number of the product that the esense system is integrated on. This parameter can be set by the system integrator during installation. Registering this number makes linking of PowerTalk reports to products in the field easier.

Service date [L2]

A date can be set for the next periodic check of the system. Currently there is no functionality added to this setting.

Production date [L3]

The date that the esense system was integrated on a product. This parameter can be set by the system integrator during installation.

Facility [L2]

A description of the facility (client) where the product is placed (e.g. “Southgate Hospital”).

NOTE: This parameter can be set at delivery of the product to make it easier to link a PowerTalk report to a specific system remotely.

Location [L2]

A description of the home location of the product (e.g. “Kitchen 7” or “Emergency Room 9”).

NOTE: This parameter can be set at delivery of the product to make it easier to link a PowerTalk report to a specific system remotely.

Energy save mode [L3]

This parameter defines timing of the energy save mode. After set minutes of inactivity (no driving, no sensors or buttons pushed) the relais on the main controller switches off the Vmotion circuit and deactivates all controllers and actuators connected.

NOTE: It is advised not to change the default setting of 1 minute.

Automatic switch off [L2]

This parameter defines timing of the automatic switch off. After set minutes of inactivity (no driving, no sensors or buttons pushed) the system switches off.

NOTE: The default setting is dependent on system type. For standard esense systems this default is 30 minutes.

Automatic pushbar switch off [L3]

This parameter defines timing of the pushbar switch off. The automatic pushbar switch off is a safety measure that prevents unattended use of the esense system. After set minutes of inactivity of the force sensor(s) the pushbar is switched off. The pushbar can be re-activated by a short push on the on/off button.

NOTE: The functionality is only active when the Automatic pushbar switch off is set on a shorter time than the Automatic switch off. For standard esense systems the default is 60 minutes, which makes the functionality inactive.

Sensor S1 [L2]

This parameter enables (1) or disables (0) force sensor channel S1.

Sensor S2 [L2]

As sensor S1.

NOTE: For a system with only one sensor either S1 or S2 must be disabled.

Sensor S1 [L3]

Changing this setting from “1” to “0” reverses the forwards direction of the sensor.

Sensor S2 [L3]

As sensor S1.

STD threshold [L3]

The pushbar STD is a measure for the stability of the sensor signal. The STD can be monitored real-time on the “Values” tab.

NOTE: A high STD is an indication of a sensor being pushed manually, a very low STD is an indication of a sensor being in rest, broken or mechanically clamped.

In case there is an input on the sensor and the real-time STD is below the STD threshold for set Detection period, the system will switch to service mode and register a “Pushbar offset fault” in the log.

NOTE: The optimal setting is partly dependent on the used sensor type (sensor handle, central force sensor or 360 sensor). Defaults are based on extensive testing and must not be changed unless advised by product specialists at Indes. Change of this setting may lead to increased risk of self-driving or pushbar errors.

Detection period [L3]

See STD threshold.

NOTE: Do not change the Detection period setting unless it is directly advised by product specialists at Indes. Change of this setting may lead to increased risk of self-driving or pushbar errors.

Offset detection torque limit [L3]

Monitoring of the STD threshold is only active when the Drivewheel torque is above this parameter. This prevents the system to switch to service mode when a trolley is held still by hand on a slope.

NOTE: Do not change the Offset detection torque limit setting unless it is directly advised by product specialists at Indes. Change of this setting may lead to increased risk of self-driving or pushbar errors.

Offset detection speed limit [L3]

Monitoring of the STD threshold is active only when Drivewheel speed is above this parameter. This prevents the system to switch to service mode when a trolley is held still by hand.

NOTE: Do not change the Offset detection speed limit setting unless it is directly advised by product specialists at Indes. Change of this setting may lead to increased risk of self-driving or pushbar errors.

Multiply factor [L3]

This setting influences the translation of manual push force to Drivewheel torque.

NOTE: A higher setting translates to a higher Drivewheel torque and less need for additional manual push force.

The optimal setting relies on the type of sensor used and the weight of the product. Advised values for regular products are:

NOTE: Selecting a higher value than advised may lead to less control during driving, increased risk of slipping and instability of the system. The risk of “BLDC undervoltage” faults increases. Changes to levels above the advised setting shall only be made after extensive testing of the product, specifically on its most critical slopes. Please contact a product specialist at Indes for specific advice.

Lock activation [L2]

This setting switches lock activation on (1) and off (0). When the function is activated the drive functionality is locked directly after start-up. It can be unlocked with use of a key-magnet or by pushing the upper hidden button 3 times in a row.

Keylock timer [L2]

The keylock is reactivated after a set period of system inactivity.

NOTE: This setting only has value when the Lock activation setting has the value “1” (active).

Polarity [L2]

The immobilizer is a switch that enables and disables drive functionality. This setting toggles polarity of the switch. Please refer to the installation instructions for further information.

NOTE: By default, no immobilizer switch is connected and the setting is “0”.

Polarity [L2]

The immobilizer is a switch that enables and disables drive functionality. This setting toggles polarity of the switch. Please refer to the installation instructions for further information.

NOTE: By default, no immobilizer switch is connected and the setting is “0”.

Max torque forward [L3]

This setting defines the maximum torque of the Drivewheel in forwards direction on a scale of 0 to -4000 (system maximum).

NOTE: Torque in forwards direction is negative (-). The default torque setting is -4000 (the system maximum).

NOTE: It is advised not to change the standard setting, unless specified by product specialists at Indes.

Max torque backwards [L3]

This setting defines the maximum torque of the Drivewheel in backwards direction on a scale of 0 to 4000 (system maximum).

NOTE: Torque in backwards direction is positive (+). The default torque is 1000. Higher levels increase the power assist in backwards direction, but also increase the risk of slipping of the wheel.

NOTE: It is advised not to change the standard setting, unless specified by product specialists at Indes.

Max assisted speed [L3]

This setting defines the maximum powered speed on a scale of 0 to 6000 (maximum assisted speed).

Example: To calculate the speed in meter/h the value must be multiplied by 1.2. For instance, a speed value of 3000 translates to 3600 m/h aka 3.6 km/h.

Unpowered speed limit [L3]

This setting triggers a safety mechanism for automatic braking. When the pushbar is released while the trolley is still moving, the trolley always brakes to standstill. As soon as the trolley stands still, the automatic brake is released; in case it starts moving again by it selves (which will typically happen when the trolley is on a slope) the automatic brake will trigger again the moment the unpowered speed limit is met.

NOTE: Only when the unpowered speed limit has not been met for 15 seconds, the brake is fully released and the Drivewheel switches to freewheel mode.

This form of braking, when a speed limit is met, is also activated during calibration and in service mode. A low setting limits maneuverability of the trolley in the first 15 seconds after automatic braking. This effect must be evaluated during system integration.

NOTE: The default setting is 6000 (over 7 km/h), which practically switches the functionality off. When a trolley is used in an environment with slopes a setting of 1000 or lower is advised.

As part of the system integration process a risk analysis shall be made by the integrator. Dependent on the conclusions of this analysis a suitable unpowered speed limit must be selected.
For situations in which trolleys are used for patient transport or when heavy trolleys are used in an environment with slopes, it is strongly advised to use an unpowered speed limit setting of 1000 or lower.

Example: To calculate the speed in meter/h the value must be multiplied by 1.2. For instance, a speed value of 1000 translates to 1200 m/h aka 1.2 km/h.

Speed ramp down [L3]

This setting defines the speed of automatic braking; a higher level decreases the braking distance but also makes the braking experience less fluent. The default setting is 22, which creates a smooth braking experience. The braking distance is dependent on speed and product weight.

Example: On a 400 kg trolley at a speed of 2.5 km/h this default setting translates to a stopping distance of approx. 1.6 m.

NOTE: It is advised not to change the speed ramp down setting to a level higher than 50. This may influence stability of the system electronics. Please contact a product specialist at Indes to discuss the best strategy to optimize and validate a setting above this level.

Speed ramp up [L3]

This setting influences the speed of sideways rotation of the Driveunit 360. The default setting is 8.

NOTE: It is advised not to change the default setting, unless specified by a product specialist at Indes.
