WARNING
LOGIC 4 ADDENDUM
N4 AND N4X MODIFICATION
WARNING
To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the
operator MUST NOT be performed until disconnecting the
electrical power and locking-out the power. Upon completion
of maintenance the area MUST be cleared and secured, at that
time the unit may be returned to service.
• Disconnect power at the fuse box BEFORE proceeding.
Operator MUST be properly grounded and connected in
accordance with local electrical codes. The operator should be
on a separate fused line of adequate capacity.
• ALL electrical connections MUST be made by a qualified
individual.
• DO NOT install ANY wiring or attempt to run the operator
without consulting the wiring diagram. We recommend that
you install an optional reversing edge BEFORE proceeding
with the control station installation.
• ALL power wiring should be on a dedicated circuit and well
protected. The location of the power disconnect should be
visible and clearly labeled.
• ALL power and control wiring MUST be run in separate
conduit.
Application
The N4 and N4X modification is for use in environments requiring
a watertight enclosure.
This addendum is to be used in conjunction with the owner’s
manual included with this operator. Refer to the manual for all
mounting, additional programming and field wiring instructions.
The N4 and N4X modification includes a TEFC motor; dynamic
braking, watertight/oiltight control enclosure; watertight/oiltight
3-button control station; LiftMaster Monitored Entrapment
Protection (LMEP) device, model CPS-UN4; and nickel-plated
chain in lieu of all standard components of the operator. For
service or replacement part requirements, use this addendum in
lieu of those included with the manual.
Leave this addendum and the owner’s manual with the owner.
Troubleshooting
FAULT
POSSIBLE CAUSE
FIX
Door coasts
significantly or
fails to stop.
1. Wiring or AUXCARD is not
properly connected.
2. Dynamic Brake is not
enabled for the operator.
3. Door is too heavy for the
operator or is not properly
balanced.
• Verify the AUXCARD is correctly seated in one of the two expansion
slots on the logic board. Verify all wiring using the wiring diagrams.
• Reprogram the operator to enable the dynamic brake. Refer to
Program the Dynamic Brake.
• Inspect the springs and other aspects of the door to make sure it is
properly balanced and can be easily lifted by the operator.
Operator resets every
time the door stops.
1. Short on transformer
secondary.
• Check the wiring. Verify that the bridge rectifier is not shorted. Verify
that all relays, including the relay on the AUXCARD, have not failed.
Program the Dynamic Brake
The Logic Board (L4) is pre-programmed to control the dynamic
brake. If the logic board is replaced the following programming
steps will be required.
1. Set selector dial to OPTN.
2. Press and release MAS.
3. Press and release MID.
4. Turn the selector dial back to the
desired wiring type.
