SPD (latch speed) pots for the desired closing operation. The door may be manually opened as
many times as necessary to complete these adjustments.
1.4 Opening Adjustments
Physically inspect the open check switch (switch with orange and yellow wires) and its associated
cam.
The arm of the open check switch should remain depressed until the door is
approximately 30° from the full open position, and then it must release . Do not proceed further
until you have verified the adjustment of this cam.
Temporarily set both the
LIMIT pot and the OBST pot fully counterclockwise. Insure that the
on/off/hold switch is in the ON position. Note whether the display is in the upper left corner of the
circuit board as installed in the header (right hand) or is in the lower right corner (left hand). If the
display is in the upper left corner, press
and hold the SET button while plugging the power
connector back into CN9 on the control. If the display is in the lower right corner, press and hold
the UP button while plugging in the power connector. This feature allows the display to read "right
side up" regardless of the control’s orientation in the header.
When power is first applied, the display will wink the current software version in three parts, as in 1
then 02 then 00 (Version 1.02.00). Next, the display should briefly flash
Su (Setup). All factory
settings for speeds, delays, and options will be saved in permanent memory, and the display will
flash
dS (data Saved). Finally, the display should switch to Id (Idle).
HINT : If the door remains closed but the display does not switch to Id , insure that the latch check
cam has been adjusted properly (Section 1.3, Closing Adjustments) and that the rocker switch is in
the
ON position. If the door tries to open, insure that the rocker switch is not in the HOLD position
instead of the ON position.
Cycle the door by pressing and holding the
DOWN button (this button functions as an actuate signal
when the door is in normal operation, allowing easier testing). The door should cycle open. The
display will show
OS (Open Speed) before the open check switch releases. It will switch to OC
(Open Check) in the open check zone. If the DOWN button is held long enough, the display will
switch to HO (Hold Open).
When the
DOWN button is released, the door will begin closing after the d1 time delay expires.
Cycle the door several times using the DOWN button and check for proper operation. If any speeds
or delays need to be changed, follow the instructions in Section 1.2, Adjustment Procedure.
WARNING: The following two paragraphs describe the limit and obstruction sensing features of the
ES500 control. The limit feature must be set properly for low energy applications. It is also highly
recommended that the obstruction -sensing feature be used for maximum pedestrian safety. The
open speed and check speeds should be properly set before attempting to adjust the added safety
features.
The
limit feature, when properly adjusted, allows faster open speed while maintaining safety by
limiting the maximum torque output of the operator. Adjust the LIMIT pot clockwise to reduce the
opening force to the desired maximum. Clockwise adjustment increases the limiting and reduces
the force available.
The
obstruction sensing feature of the ES500 control, when properly adjusted, switches the door
to a much lower hold-open force if an obstruction is encountered during door opening. Adjust the
OBST pot clockwise sufficiently to obtain an obstruction response when an obstruction is
encountered. When an obstruction is sensed, the display will switch from OS to Ob (Obstruction)
