MAXIMUM RUN TIMER (MRT)
Feature: The operator can learn the time required to open or close a
door plus an additional 10 seconds.
Benefit: If the operator does not meet the open or close contact
limit switch within the set time, the operator will stop, limiting
potential damage to the door and operator.

manually set the MRT follow the steps below.
1. Close the door.
2. Set the selector dial to PROG.

5. Once the door has reached the open position, programming is
complete.
6. Turn selector dial to desired wiring type.
NOTE: To reset MRT feature, turn selector dial to PROG and press
and hold the MRT button until the MAS LED flashes rapidly.
