Torque
1. E20 (Door Closing Torque) - Change E20 to adjust the door closing torque to a value that pro-
duces less than 30 lbs. in the center 1/2 of travel. The torque will increase as the E17 value is
increased.
Notes:
• Measure the torque with a kinetic force gauge. See Figure 11 for safe operation of the
kinetic force gauge.
• Do not set the torque low enough to affect the closing speed of the doors.
• If reduced door torque is desired, set E17=1 to enable the reduced torque option.
2. Use a kinetic force gauge to verify that the door kinetic force does not exceed the local code
requirements (typically 7 ft. lbs.). If this is a problem, reduce either the door speed or the
torque (E20).
3. Verify that the doors have enough torque to continue moving if the doors are stalled, and then
released, from all positions of door travel.
Reopen Adjustment
E11 (Smooth Turnaround) - Change E11 to adjust the initial turnaround smoothness of a reopen. A
reopen signal can be given from the safety edge, photo eye, or door open button. Test this with var-
ious door positions and adjust to achieve a fast but smooth reopen. Reopen turnaround is faster if
the E11 value is increased.
High Speed Clamp Adjustment
E19 (High Speed Clamp) - Set E19 to a value that is at least 8 more than the value of E04 (Open
High Speed).
Note:
This adjustment prevents the doors from over-speeding when a door bridge failure occurs.
Avoid setting E19 greater than 50 so that if a card failure does occur, adequate overspeed
protection will be provided. E19 must have a setting at least 8 more than the greater of
E04 or E12.
Save Door Adjustments (WRT)
1. From the startup screen of the OST, press ENTER to display the select CAR/GROUP screen (this
screen allows access to either CAR or GROUP functions).
2. Press the UP or DOWN arrow keys to display either CAR or GROUP on the second line.
3. When CAR or GROUP displays, press ENTER.
4. Use the UP or DOWN arrow keys to scroll to FRONT ELCT DOOR or REAR ELCT DOOR adjust-
ment.
5. Press ENTER to accept the selection.
6. Door adjustments are displayed.
a. To change the current value, press ENTER (an asterisk appears in front of the value).
b. Use the UP or DOWN arrow keys to change values within the allowed range.
7. When the adjustment value is correct, press ENTER. The OST displays "Hit ENTER to WRT."
8. To save the parameter, press ENTER.
