POWER-SAVING CONTROL BOX:
- The Control Box automatically powers down into ‘Standby’ mode after 20 seconds of inactivity.
- During ‘Standby’ mode, the Control Box only consumes 0.1 watt of power.
- With the Control Box in ‘Standby’ mode, the Desk or Bench can lose power without affecting the synchronization of the Lifting Columns. However, a power loss still allows the Control Box to power down and ‘Soft Reset.’ (see below)
DUTY CYCLE:
- In order to prevent excessive heat buildup and avoid damage to the system, the Control Box limits the Up-Down function of the Desk or Bench to a maximum of 1 minute of continuous operation in a 10-minute timeframe (10% duty cycle).
- To cool off the desk, wait for 20 minutes before operating the desk again.
- If the 10% duty cycle is exceeded, the Control Box may still allow limited movement, for example 3 seconds of movement after 10 seconds of rest. If further movement is desired, allow the Desk or Bench to cool off before making further adjustments.
- If the Desk or Bench does not function at all after long periods of operation, allow the Desk or Bench to cool off, until the Control Box has been idle for the entire duty cycle period.
- If the Control Box overheats, the display of the Digital / Preset Controller will read ‘HOT.’ Simply wait until the Control Box cools off, and ‘HOT’ is no longer displayed, before attempting further adjustments.
CONTROL BOX SOFT RESET:
- Unplugging the Control Box from the power source, and then plugging it back in, interrupts power to the processor inside the Control Box. This power interruption causes the processor to reset.
- If the Desk experiences unexplained freezing or erratic performance, unplug the Control Box from the power source to cut power to the processor, and reset its routine. Wait a minimum of 5 seconds, and then re-connect the power.
- If this does not restore normal performance, additional troubleshooting steps are required.
CONTROL BOX RE-INITIALIZATION:
- In the event that a ‘Soft Reset’ does not restore normal operation, a ‘Hard Reset’ may be required.
- Currently, it is necessary to use a Digital / Preset Controller to perform this operation.
- To reset the Control Box to its factory settings:
- Press memory positions 1, 2 and the Up button simultaneously for 10 seconds
- Display shows ‘S5’
- Press and hold the Up button until the display reads ‘S0’
- Press ‘ Save’; the unit is reset to factory settings
- The display shows ‘E70’ after factory reset
- Soft reset the control box (unplug and replug the power cord)
- Synchronize the lifting columns
SYNCHRONIZING/INITIALIZING LIFTING COLUMNS:
- Operate the Desk all the way down to the lowest position, and release the Down button.
- Press the Down button again, and hold.
- After a few seconds, the Desk will visibly move up and down, settling to its correct ‘bottom’ position.
- The Lifting Columns are now synchronized via the software in the Control Box.
- Operate the Desk all the way up and down to confirm proper function.
TESTING INDIVIDUAL LIFTING COLUMNS:
- The Control Box is coded to operate only when all Lifting Columns are properly connected. It is not possible to operate Lifting Columns individually for troubleshooting purposes.
- To properly identify faulty Lifting Columns, refer to Step 4 of the Troubleshooting Steps.
Any faulty Lifting Columns must be replaced. There are no field-serviceable parts inside the Lifting Column.
