Battery Handling / Storage
Refer to the battery manufacturer’s Safety Data Sheets
(01-30839 "MSDS Sheets, Battery, Standard"). LiftMaster
®
does not recommend storage of batteries in the field.
Batteries are intended for immediate use.
• The battery connections in the system are tested once
every hour. If the batteries are not connected, the
operator will attempt to close the door after DIP switch
selected Alarm Delay to Close. The alarm within the
operator will sound pattern of one second on, one
second off until the batteries are reconnected or
replaced in the event of a major fault.
• During a power loss, the operator will activate the
warning system and automatically close the door
whenever the battery voltage drops below the minimum
voltage. When this occurs the strobe will flash until the
battery is sufficiently charged.
2.2 UNIT HAS AC POWER & NO ALARM CONDITION:
• The B2/C2 control station is used to operate the door
electrically.
• Activation of the safety edge while door is closing will
cause it to reverse to full open limit.
• Activation of safety edge while the door is opening will
cause it to stop.
• Activating the optional key-test switch for at least 6
seconds will put the operator in alarm active mode
(see ACTIVE ALARM section for detail operation of
alarm active mode).
2.3 UNIT HAS AC POWER & ACTIVE ALARM CONDITION:
• The warning system will activate. The door will
automatically close after the preset time delay. The time
delay is set by means of DIP switches 1 and 2,
(See page 12).
• The door will reverse to full open limit if obstruction is
encountered while closing. The door will automatically
close again after the preset time delay. If the obstruction
is not cleared, upon the 3rd attempt to close, the door
will stop on the obstruction and activate the warning
system then release the brake. Subsequent obstruction
will cause the door to stop for two (2) seconds then
release the brake.
• After the 3rd attempt to close, the integrated braking
system controls the door’s descending speed.
2.4 UNIT HAS NO AC POWER & NO ALARM CONDITION:
• The CLOSE and STOP buttons of the B2/C2 control
station are functional. The door’s descending speed is
controlled by the integrated braking system.
• The door will stop if obstruction is encountered while
closing.
• The OPEN button is NOT functional.
2.5 UNIT HAS NO AC POWER & ACTIVE ALARM CONDITION:
• The warning system (optional) will activate. The door will
automatically close after the preset time delay. The time
delay is set by means of DIP switches 1 and 2, (See
page 12).
• If an obstruction is encountered the door will stop for 2
seconds then release the brake. Subsequent obstruction
will cause the door to stop for 2 seconds then release the
brake.
