3.) The system is behaving unusually.
Although it is not very common, a power outage or brown-out condition can
cause a motor controller to lose its programmed position. If this happens, the
motor may move in one revolution increments in one or both directions. To
remedy this problem, perform the system reset procedure below.
System Reset Procedure
•
Remove the motor cables from the “
M
” slots on the controller (
M1, M2
, etc.),
keeping the switch (the “
HS
” slot) and power cord plugged into the control box;
for dual drive systems, ensure that motor cables are removed for both control
boxes. After removing the
M1
and
M2
cables, a reset will be triggered
automatically.
•
Re-install the
M1
and
M2
plugs in to their respect ports on the control box.
•
Press and hold the down button on the switch; at this point, the system will slowly
begin moving downwards. Once the cylinders hit the bottom, they will
automatically creep forward a slight distance (to the systems “home” position).
•
After the legs have stopped, remove finger from the down button.
8.9 Limit Alteration Instructions
The system is capable of having its limits of travel changed temporarily. The upper and
lower limit can be changed independently, or in conjunction with one another, and
activated or de-activated as often as desired. It will remain set, until the user manually
unsets it. Using the low-profile switch (or any other switch with a separate up and down
button):
Setting Upper Limit:
•
Raise the system to the desired upper limit of travel. Press and hold the up and
down button simultaneously for 10 seconds, until a ‘double click’ confirmation is
heard from the control box.
Note: the upper limit must exist within the upper 50% of the system’s stroke
Setting Lower Limit:
•
Lower the system to the desired lower limit of travel. Press and hold the up and
down button simultaneously for 10 seconds, until a ‘double click’ confirmation is
heard from the control box.
Note: the lower limit must exist within the lower 50% of the system’s stroke
To unset either limit, move the system to limit, and repeat the procedure above – press
and hold the up/down buttons simultaneously for 10 seconds, until a double click is heard
from the control box. Once heard, the limit has been un-set. Repeat for each limit as
desired.
