Troubleshooting
Upper Shelf/ Work Surface will not raise or lower
•
Check the battery charge. To do this remove the ESD mat from the upper shelf/
worksurface and press the battery indicator button. If none of the LED light bars light
up then the battery needs to be recharged.
•
If the LED light bars do light up, remove the battery/ controller access panel and check
to verify battery power cable is plugged in.
•
Remove battery/ controller access cover and verify that all motor, power, and controls
cables are connected
Upper shelf/ work surface is at an angle
•
Synchronize linear motors. Remove all items from upper shelf/ work surface and from
middle shelf. Press down
˅
arrow on operator control display upper shelf/ work surface
is fully retracted, hold for 5 seconds.
ESD non-compliant on upper shelf/ work surface
•
Verify that the flooring has a RTT value of 10⁵<10⁹.
•
Verify that the ESD mat has a RTT value of 10⁵<10⁹. If it does not, clean mat and repeat
test. If it still does not pass then the mat will need to be replaced.
•
Verify that that the resistance from the mat to each conductive swivel caster has a RTG
value of 10⁵<10⁹ ohms. If this RTG value fails proceed to the next step.
•
Remove the ESD mat. Check the RTG value of 10⁵<10⁹ from the metal surface to each
conductive swivel caster. If this test passes, replace the ESD mat. If this RTG value fails
proceed to the next step.
•
Check the coiled cable to see if it connected or broken. Replace if damaged. Retest RTG
value.
•
Check ground wire connection to each conductive swivel caster (this is visible
underneath the bottom shelf). Replace if damaged. Retest the RTG value.
