Instructions
ER1

has occurred
Please check if the load is over weight capacity. If not, please
disconnect the power and reconnect after 10 minutes. If ER1 is
still shown on the panel, contact Zen Space Desks.
ER2
Over-heating in the controller has
occurred and needs to cool.
Your desk is in thermal protection mode. This is normally
nothing to worry about, and usually is an indication that the
system has experienced above-normal operating temperature
due to a number possibilities including environment, desktop
weight, or activity that is above rated specifications. Allow
your desk to cool down and remain idle for approximately 20
minutes and the ER2 continue to be displayed on the control
panel after the allotted time, please contact Zen Space Desks.
ER3
Motor cable connection fault
Disconnect the desk from power and check all cable
connections. Reconnect to power and complete a system
reset. If ER3 is still displayed, please contact Zen Space Desks
ER4
Legs at different heights
Please ensure the sync rod is installed correctly and complete
the reset process. If ER4 is still displayed or the legs will not
sync, please contact Zen Space Desks.
ER5
Voltage overload has occurred
If the control panel is unresponsive and you are unable to
adjust the desk, please disconnect from power and ensure
all cables are connected correctly. Reconnect to power after
10 minutes. If ER5 is still displayed, please contact Zen Space
Desks.
Please Note
1. Thermal protection function
The unit will enter protective mode if the system operate in excess of two minutes with “HDT” on the controller
display. The system will reset and return to normal operation after approximately 20 minutes.
2. Overload protection mode
While operating, if the load on the desk is over weight capacity, the system will enter into an overload protection
mode. This will protect the system from damages caused by exceeding weight. When this happens, the desk will
move downward approximately 30mm and come to a stop with the current height displayed.
3. Please do not disconnect the power in order to reset the unit when it is in a protective
mode or “HOT” state.
