the close button is used to close the door. (NOTE: Requires Optional failsafe
photo eyes to operate.)
FSTS Momentary button contact for open, close and stop. Radio controls
allowing open, close and stop. User set midstop. User set timer to close,
functional at open limit. The single button station opens the door and activates the
timer to close, putting the operator in TS mode until the door reaches the down
limit, or is stopped in travel. At which time the operator enters the B2 mode. A
failsafe is required to operate in this mode. (NOTE: Requires Optional failsafe
photo eyes to operate.)
NOTE:
1. External interlocks may be used with all functional modes.
2. Auxiliary devices are any devices that have only one set of contacts. Examples
are: photocell, loop detector, pneumatic or electrical treadles, residential radio
controls, one button stations, pull cords, etc.
3. Open override means that the door may be reversed while closing by activating
an opening device without the need to use the stop button first.
