Tool LEDs

The tool LEDs have the following features:

  • The front LED illuminates the work area and can be used to indicate the result status for supported tools.

  • The blue LED is part of the tool LEDs or as part of the EHMI or RHMI for supported tools. An output signal can be connected to the blue LED.

  • The status LEDs consist of a red, a yellow, and a green ring or a segmented multicolor ring on specific pistol tools. Output signals can be connected to the status LEDs.

  • A result indicator configures how the tool LEDs are lit to indicate tightening results status and the duration of this indication in supported tools.

An output signal can be of the type event or state.

A state signal is active as long as the output signal is active.

An event signal is active during the configured time range.

Blue LED

The blue LED can be configured with an event or state output signal. The signal status would be displayed with a steady light.

To configure the blue LED

  • Select a signal to connect with the blue LED.

  • Optional: set the duration of an event signal.

The blue LED is replaced by or complemented with a blue indication on the EHMI or RHMI for specific tools types.

Result Indicator

The result indicator configures how the tool LEDs are lit to indicate tightening results status and the duration of this indication.

The configuration affects the front LED and status LED result indication on supported tools. This includes pattern and duration. If pattern is set to Off, the result indication will not be used, even if Front LED is set to On in the Tool Configuration view.

Front LED must be set to On in the Tool Configuration view to use front LED result indication on supported tools.

Front LED supports the green and red color. Patterns that use the color yellow will not display yellow on the front LED.

Result indicator signals

Signal

Description

Off

No LEDs are activated after the tightening, regardless of the result.

Green

The green light always turns on when a tightening operation is OK.

Red:high:yellow:low

If the tightening is terminated incorrectly (NOK); a red LED indicates that the final value is too high, or a yellow LED indicates that the value is too low. Red and yellow can be lit simultaneously (e.g. in case of too high torque, and too low angle).

Red:high(prio):yellow:low

If the tightening is terminated incorrectly (NOK); a red LED indicates that the final value is too high, or a yellow LED indicates that the value is too low. Red and yellow cannot be lit simultaneously. Only red is lit in case of simultaneous high and low values.

Red:NOK:yellow:low

A red LED indicates that the tightening is terminated incorrectly (NOK). An additional yellow LED can indicate if the value is too low.

Red:NOK

A red LED indicates that the tightening is terminated incorrectly (NOK). No additional LEDs are shown.

Status LEDs

The status LEDs consist of LEDs in three colors: red, yellow, and green. Each light can be steady or flashing. This offers a total of six different signals that can be connected to the status LEDs.

To configure the status LEDs

  • For each color and function, steady or flashing, select an output signal from the shortcut menu.

  • Optional: set the duration of an event signal.

Status LED signals and result indications can not simultaneously be displayed on the tool. The following conditions apply:

  • A LED is turned on by a configured signal only when no tightening is ongoing and when the controlling output signal is activated.

  • A LED is turned off when the next tightening is started, even if the configured duration hasn’t been reached for an event type signal or the controlling output signal hasn’t been deactivated for a state type signal.

  • A result indication on the status LEDs will be deactivated if an update, activated or deactivated, is made to a configured signal.

Duration

The duration decides for how long the result indication will be lit after the trigger is released.

Parameter

Description

To next tightening

The blue LED, the status LEDs, and the result indication are on until the next tightening is started.

Time

The blue LED is on for the configured duration after activation.

The status LEDs are on for the configured duration after activation or until the start of the next tightening.

The result indication is on for the configured duration after the trigger is released or until the start of the next tightening.
