ADVANCED MENU
NOTE: THESE FEATURES SHOULD BE ACCESSED ONLY BY A TRAINED
TECHNICIAN AFTER INITIAL SET UP AND TESTING, ONLY IF REQUIRED.
For access to the ADVANCED MENU options press and hold the
STOP BUTTON
FOR 10 SECONDS
while on the STARTUP MENU screen. Do not release until
ADVANCED MENU appears on the screen.
REVERSING TIMER
Use this to set desired delay time for Door Reversing. If a reversing device or
function is activated when door is closing (i.e. photo-eye, load-sensing, etc.) the
door will pause by the set amount of time indicated.
Select between 0.5, 1.0, 1.5 seconds, or turn OFF. If turned OFF, door will not
reverse, but remain in place until user intervention (This is recommended when
using Closing Timer). Press STOP to Save this Setting and return to the ADVANCED
MENU.
PWM FREQUENCY
This Setting allows the user to change the operating frequency for the motor
between 2.4 kHz, 12kHz and 20kHz. Certain frequencies can interfere with third-
party accessories, and adjustment may be necessary. Factory default is set to
12kHz. Do not alter this setting unless advised by Technical Support.
DYNAMIC BRAKE
For doors that may be heavier than standard or have improperly balanced
springs that cause high closing inertia, this operator has Dynamic Braking
Options. If the door does not noticeably slow down during its intended ‘soft
stop’ (approximately in the last foot of travel), it is likely that the door will require
dynamic braking compensation.
Factory default is for no Dynamic Braking (OFF), and is recommended for
standard operation. Should Dynamic Braking prove necessary, press the OPEN/
CLOSE buttons to toggle between choices (Low, Medium & High).
Note that the addition of Dynamic Braking is intended to assist doors with
high inertia in achievement of a ‘soft stop’. It is recommend that before setting
Dynamic Braking, you first test the door at a lower closing speed. Failing this,
when setting Dynamic Braking you should start with the LOW setting first, and test
the door. If further braking is required, move to the MEDIUM setting and test, and
then the high setting. If you notice that the door makes a ‘jerking’ motion near
the bottom of its travel, the setting is too high, and it should be lowered.
OPENING FORCE
If the door is obstructed from opening (ie. due to ice buildup, the door latch
is engaged, etc.) this current monitoring feature will stop the door to prevent
damage. The sensitivity of this monitoring can be changed in this setting, or the
feature can be turned off entirely.
Opening Force sensitivity can be adjusted from 1-20 (1 being most sensitive to
obstructions/jams/imbalance) or OFF. Factory default is ‘5’.
