The Standard Quick Close modes are selectable in the Installer Menu. Refer to Table 3-2 on page 3-22.
The four selectable modes are described as follows:
Mode 1 (Default)
An input from either the Free Exit, Outside Obstruction Loop, Inside Obstruction Loop or the Center
Loop will hold the gate open, reset the close timer, and block all close inputs.
Mode 2
Same function as Mode 1, except the close timer can count to zero even with the Free Exit, Outside
Obstruction Loop, Inside Obstruction Loop or the Center Loop detector inputs active. If the close timer
has counted to zero, the gate will close when all detector inputs are clear.
Mode 3
Same function as Mode 1. However, the close timer is forced to zero when both the OOLD & IOLD are
tripped simultaneously. Additionally, all other close inputs are memorized and the gate closes immediately
when all open commands and vehicle detector inputs are clear.
Mode 4
Full anti-tailgate logic includes Mode 3 functions. In addition, the gate will stop during the opening cycle
when both OOLD & IOLD are tripped simultaneously. When the OOLD & IOLD loops are cleared, the
gate closes immediately. The OOLD & IOLD can be individually set so that, if tripped while closing, the
gate may pause only or reverse to reopen. The free exit detector input is blocked while the gate is closing.
